Zehnder ComfoAir Q	Instructions on how to integrate Zehnder ComfoAir Q350/450/600 ventilation systems into Home Assistant.	Fan Sensor	0.48	Local Push	@michaelarnauts	comfoconnect	fan sensor	integration	legacy

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 {% term "configuration.yaml" %} file. {% include integrations/restart_ha_after_config_inclusion.md %}

comfoconnect:
  host: IP_ADDRESS

{% configuration %} host: description: The IP or hostname of the ComfoConnect LAN C bridge. required: true type: string name: description: The name of this device as you want to see it in Home Assistant. required: false default: ComfoAirQ type: string token: description: The token you want to use when registering with the device. This is a random 32 char hexadecimal string. required: false default: "00000000000000000000000000000001" type: string user_agent: description: The name you want to supply when registering with the device. required: false default: "Home Assistant" type: string pin: description: The pin code to use when registering. You only need to change this if you have changed the factory default pin. required: false default: "0000" type: integer {% endconfiguration %}

To register the sensors, add the following to your {% term "configuration.yaml" %} file:

sensor:
  - platform: comfoconnect
    resources:
      - air_flow_exhaust
      - air_flow_supply
      - bypass_state
      - current_humidity
      - current_rmot
      - current_temperature
      - days_to_replace_filter
      - exhaust_fan_duty
      - exhaust_fan_speed
      - exhaust_humidity
      - exhaust_temperature
      - outside_humidity
      - outside_temperature
      - power_total
      - power_usage
      - preheater_power_total
      - preheater_power_usage
      - supply_fan_duty
      - supply_fan_speed
      - supply_humidity
      - supply_temperature

The list above indicates all supported sensors. It is recommended to only include the ones you need.

{% note %} Note that multiple connections to the bridge only work version >= U1.2.6 of the ComfoConnect LAN C bridge. In older versions it's not possible to have multiple connections to the bridge at the same time. This integration will then keep the connection open, and if you open the app, it will ask you to disconnect Home Assistant. If you close the app again, Home Assistant will reconnect automatically. {% endnote %}
