With the Elgato EVE Thermo V2, you can individually operate each radiator via the app or with your voice. The radio thermostat lets you read the current temperature in the room via the display or app. Whichever way you install the thermostat, you can tilt the display accordingly. Tell Siri that the temperature needs to go up to 21 degrees Celcius and the thermostat will do its job. Install this thermostat in every room. Operate it via the buttons on the thermostat or easily set up a daily schedule via the app. Thanks to the built-in 'open window' detector, the thermostat automatically switches off when a window is left open. The thermostat is only compatible with an iPhone, iPad, or iPod (iOS 8.1 or higher). Do you also want to operate the thermostat outside of your home? In that case, you need an Apple TV that serves as a hub. Inside you home, it works via Bluetooth.
