With the Tado Wireless Smart Thermostat V3+, you can control the temperature in your home without a fixed connection between your thermostat and your boiler. You place the included bridge on your boiler for this. This bridge is connected to your wireless thermostat. That way, you can add a smart thermostat for heat control to a house without wiring. You can also control the thermostat wherever you are with the Tado app. In the app, you can set a weekly schedule so it's always nice and warm when you come home. Because the thermostat is constantly connected to your smartphone, it knows exactly when you're near your home (geofencing). This means you won't have to heat your home unnecessarily, which saves you a lot of money. The same is true for the open window detector. When you leave a window open, the Tado app will notify you.
