The Vaillant vSMART/eRELAX Action for Google Assistant makes controlling your thermostat even easier: Just use voice commands to adjust the temperature to your liking. Feeling a bit chilly? Say: “Hey Google, raise the temperature by two degrees!” Coming home earlier than usual? Temporarily override your automated settings without even touching your phone. It is that simple to always feel completely comfortable at home. To get started, simply select "Set up device" in the Google Home app, then select "Works with Google" and link the Action to your Vaillant account.
