+## 5.2 Plant Parameter Setting Address Definition (Holding Register)
+
+The registers below can only be accessed by slave address 0 or 247. To modify plant-level registers, send commands to address 0 or 247. When sending commands to address 0, the device will only execute and will not reply. When sending commands to address 247, the device will both execute and respond.
+
+**Note:** Power control related registers not explicitly mentioned in the "Comment" will take effect only when the remote EMS control mode value is 0.

+# Meteo - Go Client for MET Norway Location Forecast API
+
+A Go client library for the [MET Norway Location Forecast API](https://api.met.no/weatherapi/locationforecast/2.0/documentation). This package provides easy access to weather forecast data from the Norwegian Meteorological Institute.
+
+## Features
+
+- Support for all three API endpoints: `compact`, `complete`, and `classic`
+- Full JSON deserialization according to the MET API specification
+- Type-safe weather symbol constants
+- Utility functions for common operations
+- Comprehensive error handling
+- Location validation
+- Time-based weather data filtering
+
+## Installation
+
+```bash
+go get github.com/devskill-org/miners-scheduler/meteo
+```
+
+## Quick Start
+
+```go
+package main
+
+import (
+    "fmt"
+    "log"
+    
+    "github.com/devskill-org/miners-scheduler/meteo"
+)
+
+func main() {
+    // Create client with proper User-Agent (required by MET API)
+    client := meteo.NewClient("MyApp/1.0 (contact@example.com)")
+    
+    // Define location (Oslo, Norway)
+    location := meteo.Location{
+        Latitude:  59.9139,
+        Longitude: 10.7522,
+        Altitude:  meteo.IntPtr(14), // Optional
+    }
+    
+    // Validate location
+    if err := meteo.ValidateLocation(location); err != nil {
+        log.Fatal(err)
+    }
+    
+    // Get forecast
+    params := meteo.QueryParams{Location: location}
+    forecast, err := client.GetCompact(params)
+    if err != nil {
+        log.Fatal(err)
+    }
+    
+    // Get current weather
+    current := forecast.GetCurrentWeather()
+    if current != nil {
+        if temp := current.GetTemperature(); temp != nil {
+            fmt.Printf("Current temperature: %.1f°C\n", *temp)
+        }
+        
+        if symbol := current.GetSymbolCode(); symbol != nil {
+            fmt.Printf("Weather: %s\n", *symbol)
+        }
+    }
+}
+```
+
+## API Endpoints
+
+### GetCompact()
+Returns essential weather parameters in a compact format. This is the most commonly used endpoint.
+
+```go
+forecast, err := client.GetCompact(params)
+```
+
+### GetComplete()
+Returns all available weather parameters. Use this when you need detailed meteorological data.
+
+```go
+forecast, err := client.GetComplete(params)
+```
+
+### GetClassic()
+Returns weather data in the classic format for backward compatibility.
+
+```go
+forecast, err := client.GetClassic(params)
+```
+
+## Data Types
+
+### Core Types
+
+- **`METJSONForecast`** - Root forecast response
+- **`Forecast`** - Main forecast data with metadata and timeseries
+- **`ForecastTimeStep`** - Individual forecast for a specific time
+- **`ForecastTimeInstant`** - Instant weather parameters
+- **`ForecastTimePeriod`** - Period-based forecast data
+- **`WeatherSymbol`** - Type-safe weather condition identifiers
+
+### Location
+
+```go
+type Location struct {
+    Latitude  float64 `json:"lat"`
+    Longitude float64 `json:"lon"`
+    Altitude  *int    `json:"altitude,omitempty"`
+}
+```
+
+## Utility Functions
+
+### Time-based Filtering
+
+```go
+// Get current weather conditions
+current := forecast.GetCurrentWeather()
+
+// Get weather for a specific time
+weather := forecast.GetWeatherAtTime(time.Now().Add(6 * time.Hour))
+
+// Get all forecasts for today
+today := forecast.GetDayForecast(time.Now())
+
+// Get forecasts for a time period
+period := forecast.GetForecastForPeriod(start, end)
+```
+
+### Weather Data Access
+
+```go
+// Check for precipitation
+hasPrecipitation := timeStep.HasPrecipitation()
+
+// Get weather parameters
+temperature := timeStep.GetTemperature()
+windSpeed := timeStep.GetWindSpeed()
+humidity := timeStep.GetHumidity()
+symbolCode := timeStep.GetSymbolCode()
+```
+
+### Weather Symbol Methods
+
+```go
+symbol := meteo.RainShowersDay
+
+isDay := symbol.IsDay()                    // true
+isNight := symbol.IsNight()               // false
+isPolarTwilight := symbol.IsPolarTwilight() // false
+hasThunder := symbol.HasThunder()         // false
+```
+
+## Weather Symbols
+
+The package includes all weather symbols as type-safe constants:
+
+```go
+meteo.ClearSkyDay
+meteo.PartlyCloudyNight
+meteo.RainAndThunder
+meteo.HeavySnow
+meteo.Fog
+// ... and many more
+```
+
+## Error Handling
+
+The package provides specific error types for different failure scenarios:
+
+```go
+forecast, err := client.GetCompact(params)
+if err != nil {
+    switch e := err.(type) {
+    case *meteo.APIError:
+        fmt.Printf("API error %d: %s\n", e.StatusCode, e.Message)
+    case *meteo.ValidationError:
+        fmt.Printf("Validation error: %s\n", e.Message)
+    case *meteo.NetworkError:
+        fmt.Printf("Network error: %v\n", e.Err)
+    default:
+        fmt.Printf("Unknown error: %v\n", err)
+    }
+}
+```
+
+## Configuration
+
+### Custom HTTP Client
+
+```go
+httpClient := &http.Client{
+    Timeout: 10 * time.Second,
+    Transport: &http.Transport{
+        TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
+    },
+}
+
+client := meteo.NewClientWithHTTPClient(httpClient, "MyApp/1.0")
+```
+
+### Custom Base URL
+
+```go
+client := meteo.NewClient("MyApp/1.0")
+client.SetBaseURL("https://custom-api.example.com/weatherapi/locationforecast/2.0")
+```
+
+## Examples
+
+### Check for Rain in the Next 24 Hours
+
+```go
+forecast, err := client.GetCompact(params)
+if err != nil {
+    return err
+}
+
+now := time.Now()
+next24h := forecast.GetForecastForPeriod(now, now.Add(24*time.Hour))
+
+for _, step := range next24h {
+    if step.HasPrecipitation() {
+        fmt.Printf("Rain expected at %s\n", step.Time.Format("15:04"))
+    }
+}
+```
+
+### Get Daily Temperature Summary
+
+```go
+dayForecast := forecast.GetDayForecast(time.Now())
+var temps []float64
+
+for _, step := range dayForecast {
+    if temp := step.GetTemperature(); temp != nil {
+        temps = append(temps, *temp)
+    }
+}
+
+if len(temps) > 0 {
+    min := temps[0]
+    max := temps[0]
+    for _, t := range temps[1:] {
+        if t < min { min = t }
+        if t > max { max = t }
+    }
+    fmt.Printf("Temperature range: %.1f°C to %.1f°C\n", min, max)
+}
+```
+
+## Requirements
+
+- Go 1.16 or later
+- Valid User-Agent string (required by MET API terms of service)
+
+## User-Agent Requirements
+
+The MET Norway API requires a proper User-Agent header that identifies your application. The format should be:
+
+```
+ApplicationName/Version (contact-email@example.com)
+```
+
+Example:
+```go
+client := meteo.NewClient("WeatherBot/2.1 (weather-support@mycompany.com)")
+```
+
+## Rate Limiting
+
+The MET API has rate limiting in place. Be respectful and cache responses when possible. The API returns standard HTTP rate limiting headers.
+
+## License
+
+This package is released under the MIT License. See the LICENSE file for details.
+
+## API Documentation
+
+For complete API documentation, visit:
+https://api.met.no/weatherapi/locationforecast/2.0/documentation
+
+## Contributing
+
+Contributions are welcome! Please feel free to submit a Pull Request.

+// API Endpoints:
+//
+// - GetCompact(): Returns a compact forecast with essential weather parameters
+// - GetComplete(): Returns the complete forecast with all available parameters
+// - GetClassic(): Returns forecast data in the classic format
+//
+// The client automatically handles JSON deserialization according to the MET API
+// specification and includes proper error handling for HTTP and validation errors.

+# Power Consumption Control
+
+This document describes the power consumption control feature for the miners scheduler.
+
+## Overview
+
+The power consumption control feature allows the scheduler to manage miners based on available PV (photovoltaic) power and configurable power limits. This ensures that the total power consumed by all miners does not exceed the available solar power or a configured maximum power limit.
+
+## Configuration
+
+The following configuration options have been added to control power consumption:
+
+### Power Limits
+
+- **`miners_power_limit`** (float64, kW): Maximum total power limit for all miners. Default: `30.0` kW
+  - This is the absolute maximum power that all miners combined can consume
+  - Even if more PV power is available, miners will not exceed this limit
+
+### Miner Power Consumption by Mode
+
+Each miner consumes different amounts of power depending on its operational mode:
+
+- **`miner_power_standby`** (float64, kW): Power consumption in standby mode. Default: `0.05` kW (50 W)
+- **`miner_power_eco`** (float64, kW): Power consumption in eco mode. Default: `0.8` kW (800 W)
+- **`miner_power_standard`** (float64, kW): Power consumption in standard mode. Default: `1.6` kW (1600 W)
+- **`miner_power_super`** (float64, kW): Power consumption in super mode. Default: `1.8` kW (1800 W)
+
+These values should be adjusted based on your specific miner hardware specifications.
+
+### Feature Toggle
+
+- **`use_pv_power_control`** (bool): Enable/disable PV power-based control. Default: `false`
+  - When `true`: The scheduler will actively manage miners based on available PV power
+  - When `false`: The scheduler uses only price-based control (legacy behavior)
+
+## How It Works
+
+### Power-Based Control Logic
+
+When `use_pv_power_control` is enabled, the scheduler implements the following logic:
+
+1. **Effective Power Limit Calculation**
+   - The effective limit is the minimum of:
+     - Available PV power (read from the plant Modbus interface)
+     - Configured `miners_power_limit`
+   - Formula: `effectiveLimit = min(availablePVPower, minersPowerLimit)`
+
+2. **Total Power Monitoring**
+   - The scheduler continuously calculates the total power consumption of all miners
+   - Power consumption is based on each miner's current state (standby/mining) and work mode (eco/standard/super)
+
+3. **Power Limit Enforcement**
+   - If total power consumption exceeds the effective limit, the scheduler will:
+     - Identify the highest power-consuming miners
+     - Progressively decrease their work modes: Super → Standard → Eco → Standby
+     - Continue until total power is within the effective limit
+
+### Integration with Existing Controls
+
+The power control system works alongside existing features:
+
+#### Price-Based Control
+- Price-based control still operates when power limits allow
+- When waking up a miner due to low electricity prices, the scheduler first checks if there's sufficient power budget
+- If waking up would exceed power limits, the miner remains in standby
+
+#### Fan Speed Control (Temperature Management)
+- The existing fan speed-based work mode adjustment continues to operate
+- Before increasing a miner's work mode based on low fan speed, the scheduler checks power limits
+- Work mode increases are blocked if they would exceed available power
+
+### Functions Modified
+
+#### `manageMiners()`
+This function now:
+1. Checks if PV power control is enabled
+2. Reads current available PV power
+3. Calculates total power consumption
+4. If exceeding limits, calls `adjustMinersForPowerLimit()` to reduce consumption
+5. When price allows waking up miners, verifies power budget is available
+6. Proceeds with standard price-based control if power allows
+
+#### `runStateCheck()`
+This function now:
+1. First checks power limits before any adjustments
+2. If exceeding limits, reduces miner modes to comply
+3. Before increasing miner modes based on fan speed, verifies power budget
+4. Continues with fan speed-based adjustments if power allows
+
+#### New Helper Functions
+
+- **`getMinerPowerConsumption(state, workMode)`**: Returns power consumption in kW for a given miner state and mode
+- **`calculateTotalPowerConsumption(minersList)`**: Calculates total power consumption of all miners in kW
+- **`adjustMinersForPowerLimit(minersList, powerLimit)`**: Adjusts miner modes to stay within power limit (power limit in kW)
+- **`GetCurrentPVPower()`**: Retrieves current PV power from the plant Modbus interface in kW
+
+## Example Configuration
+
+```json
+{
+  "use_pv_power_control": true,
+  "miners_power_limit": 30.0,
+  "miner_power_standby": 0.05,
+  "miner_power_eco": 0.8,
+  "miner_power_standard": 1.6,
+  "miner_power_super": 1.8,
+  "plant_modbus_address": "192.168.1.100:502"
+}
+```
+
+## Behavior Examples
+
+### Example 1: Insufficient PV Power
+- Available PV power: 4.0 kW
+- Miners power limit: 30.0 kW
+- Effective limit: 4.0 kW (minimum of the two)
+- Two miners in Standard mode (1.6 kW each) = 3.2 kW total
+- Result: Both miners can operate at Standard mode
+
+### Example 2: Exceeding Power Limit
+- Available PV power: 10.0 kW
+- Miners power limit: 5.0 kW
+- Effective limit: 5.0 kW
+- Three miners in Standard mode (1.6 kW each) = 4.8 kW total
+- Result: All miners can operate at Standard mode within the limit
+
+### Example 3: Cannot Wake Up Due to Power
+- Available PV power: 2.0 kW
+- Current: Two miners in Eco mode (0.8 kW each) = 1.6 kW total
+- Price drops below limit → scheduler wants to wake up a third miner
+- Adding another miner in Eco would require 2.4 kW
+- Result: Third miner remains in standby due to insufficient power
+
+## Monitoring
+
+The scheduler logs provide detailed information about power control decisions:
+
+```
+PV Power Control: Available PV power: 8.00 kW, Miners power limit: 30.00 kW
+Current total power consumption: 6.00 kW, Effective limit: 8.00 kW
+Power consumption exceeds limit, adjusting miners...
+Power limit: setting miner 192.168.1.10:4028 to Eco mode
+Power consumption now within limit: 5.50 kW <= 8.00 kW
+```
+
+## Best Practices
+
+1. **Set Accurate Power Values**: Measure or obtain from manufacturer specifications the actual power consumption of your miners in each mode
+2. **Configure Appropriate Limits**: Set `miners_power_limit` based on your electrical installation capacity
+3. **Monitor PV Power**: Ensure `plant_modbus_address` is correctly configured for accurate PV power readings
+4. **Test in Dry-Run Mode**: Use `dry_run: true` to verify behavior before enabling actual control
+5. **Consider Safety Margin**: Set power limits slightly below maximum capacity to provide safety margin
+
+## Disabling Power Control
+
+To disable power control and revert to price-only based control:
+
+```json
+{
+  "use_pv_power_control": false
+}
+```
+
+The scheduler will then only use price-based control without considering power consumption limits.

+# CI/CD Setup Summary
+
+This document provides a summary of the CI/CD infrastructure set up for the Miners Scheduler project.
+
+## 📋 Overview
+
+The project now includes a complete CI/CD pipeline using GitHub Actions that automatically:
+- ✅ Runs all unit tests on every PR and push
+- ✅ Measures code coverage
+- ✅ Performs code quality checks (linting)
+- ✅ Builds the binary to verify compilation
+- ✅ Publishes coverage badges
+- ✅ Archives test results and artifacts
+
+## 📁 Files Added
+
+### GitHub Actions Workflows
+
+1. **`.github/workflows/test.yml`**
+   - Main CI/CD workflow
+   - Runs on: pushes to main/master/develop, all pull requests
+   - Jobs:
+     - `test`: Runs tests with coverage and race detection
+     - `lint`: Runs golangci-lint for code quality
+     - `build`: Compiles the binary
+   - Uploads coverage to Codecov
+   - Archives coverage reports as artifacts
+
+2. **`.github/workflows/README.md`**
+   - Comprehensive documentation for the workflows
+   - Setup instructions for badges
+   - Troubleshooting guide
+   - Badge configuration options
+
+### Configuration Files
+
+4. **`.golangci.yml`**
+   - Configuration for golangci-lint
+   - Enables multiple linters:
+     - errcheck, gosimple, govet, ineffassign
+     - staticcheck, unused, gofmt, goimports
+     - misspell, revive, gosec, exportloopref, gocritic
+   - Custom rules and settings
+
+### Documentation
+
+5. **`CONTRIBUTING.md`**
+   - Complete contributing guide
+   - Development setup instructions
+   - Testing guidelines
+   - CI/CD pipeline explanation
+   - Pull request process
+   - Code standards and best practices
+
+6. **`.github/SETUP_COVERAGE_BADGE.md`**
+   - Detailed Codecov badge setup instructions
+   - Step-by-step setup guide
+   - Troubleshooting section
+   - Badge customization options
+
+7. **`README.md` (Updated)**
+   - Added badges section at the top:
+     - Tests status badge
+     - Coverage badge
+     - Go Report Card badge
+     - Go version badge
+     - License badge
+
+## 🚀 What Happens Now
+
+### On Every Pull Request:
+1. Tests run automatically with race detection
+2. Code is linted for quality issues
+3. Binary is compiled to ensure no build errors
+4. Coverage report is generated
+5. All checks must pass before merge
+
+### On Push to Main/Master:
+1. All the above checks run
+2. Coverage data is uploaded to Codecov
+3. Artifacts are archived for 30 days
+
+## 🎯 Next Steps
+
+### Immediate (No Configuration Required):
+The workflows will work immediately for:
+- ✅ Running tests on PRs
+- ✅ Linting code
+- ✅ Building the binary
+- ✅ Test status badge
+
+### Optional Setup (2-3 minutes):
+
+#### Codecov Badge Setup
+1. Sign up at https://codecov.io with your GitHub account
+2. Your repository will be automatically detected after the first workflow run
+3. For private repos: Add `CODECOV_TOKEN` to GitHub secrets
+4. Done! Badge updates automatically ✨
+
+**See `.github/SETUP_COVERAGE_BADGE.md` for detailed instructions.**
+
+## 📊 Coverage Goals
+
+Current guidelines:
+- Minimum: 40% (red badge)
+- Good: 60% (yellow badge)
+- Great: 80% (green badge)
+- Target: Maintain or improve with each PR
+
+## 🔧 Running Checks Locally
+
+Before pushing, run these commands to simulate CI:
+
+```bash
+# Format code
+make fmt
+
+# Run linters
+make lint
+
+# Run tests with coverage
+make test
+
+# Build binary
+make build
+
+# Or all at once
+make check test build
+```
+
+## 📈 Monitoring
+
+### View Test Results:
+1. Go to repository → Actions tab
+2. Click on any workflow run
+3. View logs for each job
+4. Download artifacts if needed
+
+### View Coverage:
+- **Locally**: Run `make test-coverage` and open `coverage.html`
+- **GitHub**: Download coverage artifact from Actions
+- **Codecov**: View dashboard at codecov.io (if configured)
+
+### View Lint Results:
+- Check the `lint` job in Actions
+- Run locally: `golangci-lint run`
+
+## 🐛 Troubleshooting
+
+### Tests Failing in CI but Passing Locally
+- Ensure same Go version (1.25.1)
+- Clear test cache: `go clean -testcache`
+- Check for race conditions: `go test -race ./...`
+
+### Lint Failing
+- Run locally: `golangci-lint run`
+- Check `.golangci.yml` for rules
+- Auto-fix some issues: `golangci-lint run --fix`
+
+### Badge Not Showing
+- Verify secrets are set correctly
+- Check workflow ran successfully
+- Clear browser cache
+- See `.github/SETUP_COVERAGE_BADGE.md`
+

+# Setting Up Coverage Badge with Codecov
+
+This guide will help you set up the Codecov coverage badge for your repository.
+
+## Overview
+
+Codecov provides free coverage tracking and badges for open-source projects. It integrates seamlessly with GitHub Actions and provides detailed coverage reports, trends, and PR comments.
+
+## Setup Steps
+
+### 1. Sign Up for Codecov
+
+1. Go to https://codecov.io
+2. Click "Sign up with GitHub"
+3. Authorize Codecov to access your GitHub account
+4. Grant Codecov access to your repositories
+
+### 2. Add Your Repository
+
+For **public repositories**:
+- Codecov will automatically detect your repository after the first workflow run
+- No additional configuration needed!
+- The workflow will upload coverage data automatically
+
+For **private repositories**:
+- You need to add a Codecov token (see step 3)
+
+### 3. Configure Token (Private Repos Only)
+
+If your repository is private:
+
+1. **Get Your Codecov Token**
+   - Navigate to https://codecov.io/gh/devskill-org/miners-scheduler
+   - Click on "Settings" in the left sidebar
+   - Copy the "Repository Upload Token"
+
+2. **Add Token to GitHub Secrets**
+   - Go to your GitHub repository
+   - Navigate to Settings → Secrets and variables → Actions
+   - Click "New repository secret"
+   - Name: `CODECOV_TOKEN`
+   - Value: Paste the token from Codecov
+   - Click "Add secret"
+
+### 4. Verify Setup
+
+1. **Commit and push** your changes (if you haven't already)
+2. **Wait for workflow** to complete (check the Actions tab)
+3. **Visit Codecov** dashboard at https://codecov.io/gh/devskill-org/miners-scheduler
+4. **Check your README** - the badge should now display the coverage percentage
+
+## Badge Configuration
+
+The coverage badge is already configured in your README.md:
+
+```markdown
+[![Coverage](https://codecov.io/gh/devskill-org/miners-scheduler/branch/main/graph/badge.svg)](https://codecov.io/gh/devskill-org/miners-scheduler)
+```
+
+If you use a different default branch (e.g., `master`), update the badge URL:
+
+```markdown
+[![Coverage](https://codecov.io/gh/devskill-org/miners-scheduler/branch/master/graph/badge.svg)](https://codecov.io/gh/devskill-org/miners-scheduler)
+```
+
+## Codecov Features
+
+Once set up, Codecov provides:
+
+### Coverage Dashboard
+- Overall coverage percentage
+- Coverage trends over time
+- File-by-file coverage breakdown
+- Uncovered lines highlighted
+
+### Pull Request Comments
+- Automatic comments on PRs showing coverage changes
+- Coverage diff (increase/decrease)
+- New uncovered lines highlighted
+- Pass/fail status based on coverage thresholds
+
+### Coverage Graphs
+- Coverage history graphs
+- Sunburst and tree visualizations
+- Compare coverage across branches
+
+### Notifications
+- Slack/Email notifications for coverage changes
+- Customizable coverage thresholds
+- CI status checks
+
+## Badge Customization
+
+You can customize your badge appearance:
+
+### Default Badge
+```markdown
+[![Coverage](https://codecov.io/gh/devskill-org/miners-scheduler/branch/main/graph/badge.svg)](https://codecov.io/gh/devskill-org/miners-scheduler)
+```
+
+### Flat Style Badge
+```markdown
+[![Coverage](https://codecov.io/gh/devskill-org/miners-scheduler/branch/main/graph/badge.svg?style=flat)](https://codecov.io/gh/devskill-org/miners-scheduler)
+```
+
+### Flat-Square Style Badge
+```markdown
+[![Coverage](https://codecov.io/gh/devskill-org/miners-scheduler/branch/main/graph/badge.svg?style=flat-square)](https://codecov.io/gh/devskill-org/miners-scheduler)
+```
+
+## Troubleshooting
+
+### Badge Shows "unknown"
+
+**Possible causes:**
+- Workflow hasn't run yet
+- Coverage upload failed
+- Repository not found on Codecov
+
+**Solutions:**
+1. Check that the workflow completed successfully in the Actions tab
+2. Verify the Codecov upload step didn't fail
+3. For private repos, ensure `CODECOV_TOKEN` is set correctly
+4. Visit Codecov dashboard to check for error messages
+
+### Coverage Not Uploading
+
+**Possible causes:**
+- Token is incorrect (private repos)
+- Network issues during upload
+- Coverage file not generated
+
+**Solutions:**
+1. Check the workflow logs for the "Upload coverage to Codecov" step
+2. Verify `coverage.out` file is being generated
+3. For private repos, double-check the `CODECOV_TOKEN` secret
+4. Try re-running the workflow
+
+### Badge Not Updating
+
+**Possible causes:**
+- Browser cache
+- Badge URL pointing to wrong branch
+- Codecov processing delay
+
+**Solutions:**
+1. Clear your browser cache or try incognito mode
+2. Verify the branch name in the badge URL matches your default branch
+3. Wait a few minutes - Codecov may take time to process
+4. Add a version parameter to force refresh: `?v=1`
+
+### Private Repo: "401 Unauthorized"
+
+**Solution:**
+- Ensure `CODECOV_TOKEN` secret is set in GitHub repository settings
+- Verify the token is correct (copy from Codecov settings)
+- Token must have the correct permissions
+
+## Configuration Options
+
+### Codecov YAML Configuration (Optional)
+
+You can add a `codecov.yml` file to your repository root for advanced configuration:
+
+```yaml
+# codecov.yml
+coverage:
+  status:
+    project:
+      default:
+        target: 70%        # Target coverage
+        threshold: 2%      # Allow 2% drop
+    patch:
+      default:
+        target: 80%        # New code should have 80% coverage
+
+comment:
+  layout: "reach, diff, flags, files"
+  behavior: default
+
+ignore:
+  - "test_data/**"
+  - "**/*_test.go"
+```
+
+### Coverage Thresholds
+
+Set minimum coverage requirements:
+
+```yaml
+coverage:
+  status:
+    project:
+      default:
+        target: auto
+        threshold: 1%
+        if_ci_failed: error
+```
+
+## Best Practices
+
+1. **Set Realistic Targets**
+   - Start with current coverage as baseline
+   - Gradually increase target over time
+   - Don't set unrealistic 100% targets
+
+2. **Review Coverage Reports**
+   - Check coverage in PRs before merging
+   - Focus on covering critical paths
+   - Use coverage to find untested code
+
+3. **Monitor Trends**
+   - Watch for coverage decreases
+   - Celebrate coverage improvements
+   - Use graphs to track progress
+
+4. **Ignore Appropriate Files**
+   - Test files don't need coverage
+   - Generated code can be ignored
+   - Vendor directories should be excluded
+
+5. **Educate Team**
+   - Share coverage reports with team
+   - Discuss coverage in code reviews
+   - Make coverage part of your workflow

+# GitHub Actions Workflows
+
+This directory contains GitHub Actions workflows for automated testing, code coverage, and continuous integration.
+
+## Workflows
+
+### Tests and Coverage (`test.yml`)
+
+This workflow runs on every push to main/master/develop branches and on all pull requests.
+
+**Jobs:**
+- **test**: Runs all unit tests with race detection and generates code coverage
+- **lint**: Runs golangci-lint for code quality checks
+- **build**: Builds the binary to ensure compilation succeeds
+
+**Features:**

+- ✅ Race condition detection
+- ✅ Code coverage measurement
+- ✅ Uploads coverage to Codecov
+- ✅ Archives coverage reports as artifacts
+
+## Setup Instructions
+
+### Basic Setup (Works Immediately)
+
+The `test.yml` workflow will work out of the box for:
+- Running tests on PRs and pushes
+- Generating coverage reports
+- Linting code
+- Building the binary
+
+Simply commit the workflow files and they will run automatically.
+
+### Codecov Integration (Optional)

+   - The badge in README.md will automatically update
+
+**Badge:**
+```markdown
+[![Coverage](https://codecov.io/gh/devskill-org/miners-scheduler/branch/main/graph/badge.svg)](https://codecov.io/gh/devskill-org/miners-scheduler)
+```
+
+### Alternative: Simple Test Status Badge
+
+If you don't want to use Codecov, you can use just the test status badge:
+
+```markdown
+[![Tests](https://github.com/devskill-org/miners-scheduler/actions/workflows/test.yml/badge.svg)](https://github.com/devskill-org/miners-scheduler/actions/workflows/test.yml)
+```
+
+## Viewing Coverage Reports
+
+### In Codecov
+1. Visit https://codecov.io/gh/devskill-org/miners-scheduler
+2. View coverage percentage, trends, and file-by-file breakdown
+3. See coverage changes in pull requests
+
+### In GitHub Actions
+1. Go to the Actions tab in your repository
+2. Click on a workflow run
+3. Scroll to "Artifacts" section
+4. Download `code-coverage-report`
+
+### Locally
+Run the coverage report locally:
+
+```bash
+# Generate coverage
+make test-coverage
+
+# Or manually
+go test -coverprofile=coverage.out ./...
+go tool cover -html=coverage.out -o coverage.html
+```
+
+Then open `coverage.html` in your browser.
+
+## Workflow Triggers
+
+### test.yml
+- ✅ Push to `main`, `master`, or `develop` branches
+- ✅ Pull requests targeting `main`, `master`, or `develop`
+
+## Status Badges
+
+Add these badges to your README.md:
+
+```markdown
+[![Tests](https://github.com/devskill-org/miners-scheduler/actions/workflows/test.yml/badge.svg)](https://github.com/devskill-org/miners-scheduler/actions/workflows/test.yml)
+[![Coverage](https://codecov.io/gh/devskill-org/miners-scheduler/branch/main/graph/badge.svg)](https://codecov.io/gh/devskill-org/miners-scheduler)
+[![Go Report Card](https://goreportcard.com/badge/github.com/devskill-org/miners-scheduler)](https://goreportcard.com/report/github.com/devskill-org/miners-scheduler)
+```
+
+## Troubleshooting
+
+### Tests fail locally but pass in CI (or vice versa)
+- Ensure Go version matches between local and CI (currently 1.25.1)
+- Check for race conditions with `go test -race ./...`
+- Clear test cache: `go clean -testcache`
+
+### Coverage not uploading to Codecov
+- Check that workflow ran successfully
+- For private repos, verify `CODECOV_TOKEN` secret is set correctly
+- Check Codecov dashboard for error messages
+- Ensure repository is added to Codecov
+
+### Lint failures
+- Run locally: `golangci-lint run`
+- Install: `brew install golangci-lint` (macOS) or see https://golangci-lint.run/usage/install/
+- Fix issues or adjust `.golangci.yml` configuration

+
+```bash
+# Using Make
+make vet
+
+# Or manually
+go vet ./...
+```
+
+### Run All Checks
+
+```bash
+make check
+```
+
+## CI/CD Pipeline
+
+Our CI/CD pipeline automatically runs on:
+- Every push to `main`, `master`, or `develop` branches
+- Every pull request targeting these branches
+
+### What the CI Pipeline Does
+
+1. **Test Job**:
+   - Runs all unit tests
+   - Enables race detection
+   - Generates code coverage reports
+   - Uploads coverage to Codecov (if configured)
+   - Creates coverage badge
+   - Archives coverage reports
+
+2. **Lint Job**:
+   - Runs golangci-lint with comprehensive checks
+   - Ensures code quality standards
+
+3. **Build Job**:
+   - Compiles the binary
+   - Verifies successful build
+   - Archives build artifacts
+
+### Viewing CI Results
+
+1. Navigate to the "Actions" tab in the GitHub repository
+2. Click on the workflow run you want to inspect
+3. Review job results and logs
+4. Download artifacts if needed
+
+### Local CI Simulation
+
+Before pushing, you can simulate CI checks locally:
+
+```bash
+# Run the same checks as CI
+make check test build
+
+# Or step by step
+make fmt      # Format code
+make vet      # Run go vet
+make lint     # Run golangci-lint
+make test     # Run tests with coverage
+make build    # Build binary
+```
+
+## Pull Request Process
+
+### Before Submitting
+
+1. **Create a feature branch**:
+   ```bash
+   git checkout -b feature/your-feature-name
+   ```
+
+2. **Make your changes** and commit them:
+   ```bash
+   git add .
+   git commit -m "Description of your changes"
+   ```
+
+3. **Run all checks locally**:
+   ```bash
+   make check test
+   ```
+
+4. **Update tests** if you've added functionality
+
+5. **Update documentation** if needed
+
+6. **Sync with upstream**:
+   ```bash
+   git fetch upstream
+   git rebase upstream/main
+   ```
+
+### Submitting the PR
+
+1. Push your branch:
+   ```bash
+   git push origin feature/your-feature-name
+   ```
+
+2. Open a Pull Request on GitHub
+
+3. Fill out the PR template with:
+   - Description of changes
+   - Related issues
+   - Testing performed
+   - Screenshots (if applicable)
+
+4. Wait for CI checks to pass (all three jobs must succeed)
+
+5. Request review from maintainers
+
+### PR Requirements
+
+- ✅ All CI checks must pass
+- ✅ Code coverage should not decrease
+- ✅ All tests must pass
+- ✅ Code must be formatted (`make fmt`)
+- ✅ No linting errors
+- ✅ Documentation updated if needed
+- ✅ At least one approving review
+
+## Code Coverage
+
+We aim to maintain high code coverage (>70%). 
+
+### Coverage Guidelines
+
+- New features should include tests
+- Bug fixes should include regression tests
+- Critical paths should have >90% coverage
+- Coverage should not decrease with new PRs
+
+### Viewing Coverage Locally
+
+```bash
+# Generate and view coverage
+make test-coverage
+
+# Open coverage.html in your browser
+```
+
+### Coverage in CI
+
+- Coverage is automatically calculated on every PR
+- Coverage badge is updated on main branch
+- Coverage reports are archived as artifacts
+
+## Coding Standards
+
+### Go Best Practices
+
+- Follow [Effective Go](https://golang.org/doc/effective_go.html)
+- Use `gofmt` for formatting
+- Write clear, descriptive variable and function names
+- Add comments for exported functions and types
+- Keep functions small and focused
+- Handle errors explicitly
+
+### Code Organization
+
+```
+miners-scheduler/
+├── entsoe/          # ENTSO-E API client
+├── meteo/           # Weather/meteorological data
+├── miners/          # Miner control logic
+├── mpc/             # Model Predictive Control

+├── sun/             # Solar calculations
+├── utils/           # Utility functions
+└── test_data/       # Test fixtures
+```
+
+### Testing Standards
+
+- Write table-driven tests where appropriate
+- Use descriptive test names: `TestFunctionName_Scenario_ExpectedResult`
+- Mock external dependencies
+- Test error paths, not just happy paths
+- Use `t.Run()` for subtests
+
+Example:
+```go
+func TestScheduler_Run_WithHighPrice_StopsMiners(t *testing.T) {
+    // Arrange
+    scheduler := NewScheduler(...)
+    
+    // Act
+    err := scheduler.Run()
+    
+    // Assert
+    if err != nil {
+        t.Errorf("unexpected error: %v", err)
+    }
+}
+```
+
+### Commit Messages
+
+Follow conventional commits format:
+
+```
+type(scope): subject
+
+body
+
+footer
+```
+
+Types:
+- `feat`: New feature
+- `fix`: Bug fix
+- `docs`: Documentation changes
+- `test`: Adding or updating tests
+- `refactor`: Code refactoring
+- `style`: Formatting changes
+- `chore`: Maintenance tasks
+- `ci`: CI/CD changes
+
+Example:
+```
+feat(scheduler): add thermal protection for miners
+
+Implements automatic mode switching when fan speeds exceed 70%
+to prevent overheating. Recovers to standard mode when temps normalize.
+
+Closes #123
+```
+
+## Getting Help
+
+- Open an issue for bugs or feature requests
+- Use discussions for questions
+- Check existing issues and PRs before creating new ones
