Compared to traditional WiFi Sockets that only let you switch the heater ON/OFF the Mill WiFi Socket has an integrated temperature sensor that enables you to adjust the temperature of your heater in the Mill app. Mill WiFi Socket is specialized for heaters and works in the same way as a Mill heater with integrated WiFi, as the temperature sensor will tell you the temperature in the room in the Mill App, letting you control the heater from anywhere. And best of all, by using the socket on your old heater you do not have to buy a new one – saving your wallet and the environment!
