Even if your home isn’t modern it can still be smart with the Netatmo Valves for Radiators. This compact and sleek device replaces the existing valve on your radiator. Connecting to your smartphone, the Valves can be independently controlled so you can only heat rooms that you’d like. Using the app, you can set each Valve in each room to a different schedule depending on who’s home and when. Additionally, the Valves use the latest technology to sense when a window has been opened and will turn off to save energy. Working with HomeKit, the Valves are also able to sense when people enter the room to adjust the temperature automatically. Complete with an e-ink display on the top for easy viewing, the Valves make heating older homes a breeze.
