Zehnder ComfoAir Q
The comfoconnect
integration lets you control Zehnder ComfoAir Q350/Q450/Q600
ventilation units from Home Assistant. You need a ComfoConnect LAN C
bridge to connect the unit to your local network.
There is an official iPhone and Android app to configure and control your unit. This platform connects with the help of the unofficial pycomfoconnect library.
The integration has a fan platform to view and control the ventilation speed, and a sensors platform to read out the outdoor temperature and humidity, the indoor temperature and humidity, and the extract and supply air flow (in m³ per hour).
To set it up, add the following information to your configuration.yaml
The configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI.[Learn more] file.
