OpenQuatt

OpenQuatt connects Homey Pro directly to the OpenQuatt heat pump controller on your own network. The controller is discovered automatically and all data arrives in real time over a live local connection — no polling and no cloud account needed. Monitor supply, outside and room temperatures, power consumption, the active control mode and the aux relay, and switch manual cooling or the relay straight from Homey. Automate everything with an extensive set of Flow cards for heating, cooling, faults, defrosting, the boiler and silent mode, and feed the dew point from your own room sensors so the controller can cool safely without condensation. A dashboard widget shows live temperatures, power, efficiency and status at a glance. Requires a Quatt heat pump running the OpenQuatt firmware and a Homey Pro (Early 2023 or newer).
