A custom integration for Home Assistant to control and monitor the Maico Powerbox WS 75 ventilation system. The device provides decentralized ventilation with heat and humidity recovery.

With this integration, you can monitor and manage key features of the Maico Powerbox WS 75, including operation mode and ventilation level switching, monitoring of temperature and air humidity values and controlling device parameters directly from Home Assistant.

The integration uses the device's ability to communication via modbus. You have to make sure that the powerbox is connected to your Network (either wired or WiFi) and modbus is activated. This requires to disable the AIR@home feature. You'll probably have to connect to the device via USB using the 'KWL-Inbetriebnahme-Software' in order to set things up.
