About

Dantherm is a local integration that connects Dantherm ventilation units to Home Assistant over Modbus TCP/IP. It adds a fan for ventilation, a bypass damper cover, switches for away, night, fireplace, summer, boost, eco and home modes, plus sensors for temperatures, humidity, air quality and alarms. Numbers, selects and texts cover filter lifetime, humidity setpoints, bypass temperatures and night mode times, and buttons reset the filter and alarms. Adaptive triggers can link boost, eco and home modes to other entities, and a calendar entity handles scheduling. Actions set the unit state and configuration, reset the filter or alarm, and clear the adaptive event stack. Setup runs in the UI with optional automatic discovery, and the interface is available in Danish, Dutch, English, German and French.
