# Zehnder ComfoConnect PRO

> Zehnder ComfoConnect PRO is a Marketplace integration for Home Assistant. It has 117 installs sharing analytics, works locally and was last updated September 22, 2026.

Zehnder ComfoConnect PRO is a custom integration that connects Home Assistant to a Zehnder ComfoConnect PRO ventilation interface. It communicates locally with the interface over Modbus TCP, which has to be enabled in the interface's web page first. It adds a climate entity, sensors for air temperatures, supply fan volume, connection state and error codes, and binary sensors for error, standby, ComfoHood and filter replacement. Controls include switches for boost, auto mode, away function, ComfoCool and acknowledging errors, plus selects for ventilation preset and temperature profile. Numbers cover the external setpoint and boost time. Setup is done in the UI with a name, host, port, host ID and scan interval, and it needs the Marketplace.
