It has 3.9k installs sharing analytics, needs the vendor's cloud and was last updated July 22, 2026. myVAILLANT is an integration that controls Vaillant heating devices such as aroTHERM heat pumps and ecoTEC boilers through the myVAILLANT cloud API. It also works with branded versions of the API, such as the MiGo Link app from Saunier Duval and Bulex, selectable through a brand setting. It adds climate and water heater controls, along with sensors, switches, numbers, calendars, dates and times, and binary sensors. Operating modes, target temperature and presets such as holiday mode or quick veto can be controlled, and custom services set schedules for climate zones, water heaters and circulation pumps. Sensors cover temperature, humidity, energy usage and efficiency, plus diagnostics such as heating curve, flow temperature, firmware versions and water pressure. Options cover update intervals, default durations for quick veto and away mode, and whether temperature controls overwrite the time program; setup is done in the UI with the app account login.
