README - Pilot Wire Integration for Home Assistant

Overview

This Home Assistant integration simplifies the setup of pilot wire modules for heating systems, providing seamless conversion of multiple entities (select and power) into a unified climate entity. An optional temperature sensor entity can also be added. This integration is ideal for controlling pilot wire heating modules, enabling streamlined control and monitoring of heating states.

Key Features

• Converts select and power entities into a single climate entity.
• Utilizes the select entity to adjust the pilot wire preset modes.
• Uses the power entity to detect whether the heating is on or off.
• Configurable power threshold to determine heating state.
• Configurable default power on preset.
• Optional support for temperature sensor entities.

Compatibility

The integration is compatible with the following devices or any climate manageable with a select entity :

• Equation: SIN-4-FP-21_EQU
• Legrand: 064882
• NodOn: SIN-4-FP-20, SIN-4-FP-21

Installation

Option 1: Using HACS (Home Assistant Community Store)

1. Use the button above or search for "Wire Pilot Climate" in HACS
2. Download the integration and restart Home Assistant

Option 2: Manual Installation

1. Copy the integration files to your Home Assistant custom components directory.
2. Restart Home Assistant.
3. Add the integration through the Home Assistant UI or by modifying the configuration.yaml file.

Configuration

To set up this integration, you can either add it through the Home Assistant UI or configure it manually. Below is a sample configuration.yaml setup.

Important

This integration is implemented as a Helper in Home Assistant and is not a full-fledged custom integration.

To initialize this helper, follow this path in your Home Assistant interface:

1. Settings
2. Devices and Services
3. Helpers
4. Create Helper
5. Pilot Wire Thermostat

Once configured, the climate entity will appear in the Helpers tab. It will be automatically linked to the device of the select entity you chose during setup.

YAML configuration

If you prefer to use yaml, you can, but it's not recommended as more and more integrations are moved to the UI. All the options are available in the UI.

Key	Type	Required	Description
platform	string	yes	pilot_wire_climate
presets	string	yes	Select entity id to adjust the pilot wire preset modes
power	string	no	Power sensor to detect whether the heating is on or off
temperature	string	no	Temperature sensor id (for display)
additional_modes	boolean	no	6-order support (add Comfort -1 and Comfort -2 preset)
power_threshold	integer	no	Power threshold (in watts) above which the heater is considered to be heating
default_preset	string	no	Default 'power on' preset from "frost_protection", "eco", "comfort-2", "comfort-1" "comfort"
name	string	no	Name to use in the frontend
unique_id	string	no	An ID that uniquely identifies this climate. If two climates have the same unique ID, Home Assistant will raise an error

The unique id is recommended to allow icon, entity_id or name changes from the UI.
