Viessmann condensing gas wall-hung boilers now integrate with the Mi Home app. Users can manage heating settings remotely, including turning the device on or off and adjusting temperatures, by linking their Viessmann account through the app's third-party platform connection feature.

The integration supports Xiaomi HyperOS Connect and voice control via Xiao Ai. Users can issue voice commands to toggle the boiler or change temperature settings. This functionality follows the standard cloud-to-cloud authorization process used by other brands like LG, Bosch, and Siemens within the Mi Home ecosystem.

Viessmann, a German manufacturer founded in 1917, specializes in heating, cooling, and air conditioning systems. Its boiler lineup includes the 100, 200, and 300 series. In June 2023, Carrier Global Corporation acquired Viessmann's European climate solutions business, incorporating the company into its corporate structure.

Xiaomi introduced its HyperOS Connect technology brand in November 2023 to provide cross-device connectivity for developers. The ecosystem currently includes over 9,000 brand partners. Previously, some users connected Viessmann boilers to Mi Home using third-party Bluetooth Mesh hardware.
