Mill WiFi Socket

Mill WiFi Socket makes your old heater “smart” and connects it to WiFi and the Mill app.
What makes Mill WiFi Socket different from other WiFi sockets? Mill WiFi Socket has an integrated temperature sensor that enables you to adjust the temperature of your heater in the Mill app from anywhere, compared to traditional WiFi Sockets that only let you switch the heater ON/OFF. Mill WiFi Socket is in this sense 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. And best of all – you can use it on your old and “dumb” heater, so that you do not have to buy a new one – saving your wallet and the environment!

  • Mill WiFi Socket applies to all heaters with mechanical thermostat and most heaters with electronic thermostats (heaters able to remember the last set temperature after a power cut).

  • The Mill app gives you the freedom to control your heaters from anywhere in the world, at a touch of a button. By using the app you can control different locations (home, cabins etc) and as many heaters as you want. Search for “Mill Norway” in Google Play and App Store.
