Save energy with a wired thermostat. You can connect the smart thermostat via wiring to your heating system, for example your boiler or heat pump. You can connect it to the app on your smartphone via WiFi. You can set the temperature there and keep an eye on your energy consumption. You can also enjoy other smart functions, such as smart schedules. A self-learning wall thermostat learns from your habits and adjusts the temperature itself. This way, you never heat too much.
