Control multiple rooms in your home the smart way with the Bosch Slimme Radiatorknop 2 Duo Pack. Place the radiator knobs on radiators with a radiator valve that lets you control the temperature, and set a separate temperature and heating schedule for each radiator. This way, you only heat the rooms you actually use. That's useful if you want more control over your heating in each room. You can also connect the radiator knobs to other smart platforms via Matter, so they fit well into your existing smart home. Control the knobs via the Bosch Smart Home app, and automate your heating for each room. For most smart features within the Bosch system, you do need a Bosch Smart Home Controller.
