Control multiple radiators in your home right away with this Bosch starter pack. You place the 5 radiator knobs on radiators with a radiator valve that lets you control the temperature, and connect them to the Bosch Smart Home Controller 2. This lets you set a separate temperature and heating schedule for each radiator or room in the Bosch Smart Home app. Useful if you want to heat different rooms separately. You can also connect the radiator knobs to other smart platforms via Matter. The controller is the central hub of your Bosch smart home and makes extra automations possible. This way, you can easily expand your system later with other Bosch Smart Home devices.
