It has 236 installs sharing analytics, works locally and was last updated October 8, 2026. Weishaupt WBB monitors and controls compatible Weishaupt heat pumps locally over their built-in Modbus TCP interface. It adds sensors, numbers and selects for values the heat pump exposes, including heating circuits, domestic hot water, heat pump data, statistics and configurable setpoints. Operation modes, pause and party settings, heating curves and temperature limits can be adjusted from Home Assistant. An optional power-mapping file lets the integration calculate heat output from reported power demand, outside temperature and water temperature. The supplied mapping is based on a Weishaupt WBB 12, so other models may need their own mapping. It does not work with heat pumps that only offer the separate Weishaupt Modbus module, and it is set up in the UI with the heat pump host and port.
