How to Control Your Heat Pump with Home Assistant Integrations

This article explains how to control a heat pump from Home Assistant using available APIs and integration methods.

Controlling Your Heat Pump from Home Assistant

Available Integration Methods

  1. Local API: A local API is planned to be launched, which will allow direct control of the heat pump without going through the cloud. This will provide a more stable connection.

  2. Modbus TCP: This method is currently available and can be used to control the heat pump. Users can integrate their heat pump with Home Assistant using Modbus TCP.

  3. MQTT: An MQTT connection will also be available for local control of the heat pump, allowing for efficient communication within a home network.

  4. SG Signals: The heat pump can be controlled using SG signals, which may be compatible with certain setups.

Recommendations for Integration

  • If you are already using Modbus TCP for other devices, it is recommended to continue using this method for the heat pump until the local API is available.
  • For users comfortable with building custom solutions, creating an ESP32 setup with relays is an option for controlling the heat pump.

Documentation and Support

  • Current documentation for the APIs is available on the official API page. However, users have noted a lack of detailed documentation regarding specific functionalities, such as forcing the heat pump to produce hot water on demand.
  • For further assistance and updates on the local API launch, users are encouraged to check the official channels or forums dedicated to heat pump control.

Conclusion

Controlling your heat pump from Home Assistant is feasible through various integration methods, including Modbus TCP and upcoming local API options. Users should stay informed about new developments and utilize existing resources for effective integration.
