Anker Solix Tibber Blueprint for Home Assistant

Smart charge/discharge automation for an Anker Solix Solarbank controlled by Tibber (or compatible) dynamic electricity prices, with automatic fallback to the Anker app's "smart" mode.

What it does

• Charges the battery from the grid during the cheapest part of the day (default: 1.5 hours before through 1.5 hours after the cheapest Tibber slot).
• Discharges to the grid during the most expensive part of the day (default: 1.0 hour before through 1.0 hour after the most expensive Tibber slot).
• Falls back to smart mode the rest of the time — the Anker app keeps doing its normal balancing.
• Overlap-safe: if the charge and discharge windows would overlap, the blueprint does nothing and leaves the Solarbank in smart.
• Idempotent: runs every minute but only issues API calls when something actually needs to change.

Requirements

• Home Assistant (tested on 2026.5.x)
• Anker Solix custom integration installed via HACS
• A dynamic-price sensor whose state attribute contains a list of { start: <ISO timestamp>, price: <float> } objects.
  • Out-of-the-box compatible with Tibber Smart: use sensor.tibber_smart_prices_today and attribute prices_today.
  • Other integrations work if they expose the same shape — set the attribute name in the blueprint inputs.

Installation

1. Import the blueprint

Or manually: Settings → Automations → Blueprints → Import Blueprint and paste:

https://raw.githubusercontent.com/Adcompro/ha-anker-solix-tibber-blueprint/main/blueprints/automation/tibber_charge_discharge.yaml

2. Create an automation from it

Settings → Automations → Create Automation → Use Blueprint → Anker Solix - Tibber slim laden en terugleveren

Fill in:

Input	Example
Prices sensor	sensor.tibber_smart_prices_today
Prices attribute	prices_today
Usage mode select	select.solarbank_3_e2700_pro_usage_mode_2
Smart mode option	smart
Manual mode option	manual
Output preset number	number.solarbank_3_e2700_pro_system_output_preset_2
Backup option switch	switch.solarbank_3_e2700_pro_backup_option_2
Grid export switch	switch.solarbank_3_e2700_pro_allow_grid_export
Hours before cheapest slot	1.5
Hours after cheapest slot	1.5
Hours before most-expensive slot	1.0
Hours after most-expensive slot	1.0
Max discharge power	2400
Enable boolean (optional)	leave empty, or your own input_boolean.* toggle

3. Set the Anker app to smart mode

The Solarbank will only be temporarily flipped to manual during the charge or discharge windows and immediately reset to smart afterwards. So keep the Anker app on smart — Home Assistant takes over only when needed.

How it works

Every minute (and on price updates) the automation:

1. Reads prices_today from the configured sensor.
2. Finds the slot with the lowest and the slot with the highest price.
3. Computes the charge window [cheapest − before, cheapest + after] and the discharge window [expensive − before, expensive + after].
4. Decides the target state — charge, discharge, or smart:
   • charge if now is in the charge window and windows don't overlap.
   • discharge if now is in the discharge window and windows don't overlap.
   • Otherwise smart.
5. Compares against the current Solarbank state (mode + switches + output) and only issues service calls if a change is actually needed.

Target	usage_mode	backup_option	allow_grid_export	output_preset
charge	manual	on	off	0 W
discharge	manual	off	on	configurable max W
smart	smart	off	off	(unchanged)

Alternative: stand-alone package

If you prefer visible state entities (charge window active, discharge window active, windows overlap) and separate start/stop automations instead of one blueprint-driven automation, copy battery_optimizer_package.yaml from this repository into your Home Assistant packages/ directory.

That version exposes:

• sensor.solix_goedkoopste_slot / sensor.solix_duurste_slot
• binary_sensor.solix_laadvenster_actief
• binary_sensor.solix_ontlaadvenster_actief
• binary_sensor.solix_vensters_overlappen

Edit the entity_ids inside the file to match your Solarbank.

Caveats

• Tibber's prices_today attribute is in 15-minute slots. "Cheapest slot" means the cheapest 15-minute interval — the charge window then extends symmetrically around the START of that interval.
• Edge case: when the cheapest/most-expensive slot is near midnight, part of the window may fall on the previous/next day and won't activate as expected. Acceptable for the common case but worth knowing.
• The blueprint sets the Solarbank to manual mode during windows. Make sure you're OK with that — the Anker app will show "manual" briefly.
