Save money with smart radiator knobs.

With the Hombli Smart Radiator Thermostat you’re able to control the temperature per room. As a result, you no longer need to heat your entire house, but only the rooms within which you are present. With the easy weekly schedule, you will always come home to a comfortable house and never heat unnecessarily.

Thanks to all the smart energy-saving features of this radiator knob, you can save up to 30% on your heating costs. For an average European household, this amounts to a payback period of 1 to 3 months, after this period the savings really start!

Smart weekly schedule
Always come home to a comfortably warm house thanks to the handy weekly schedule. With the app you can easily raise or lower the temperature per room. You can also apply these settings for several days at once. Are you going away temporarily? Then set the thermostat knob to ‘away’ mode to keep the temperature down and ignore all schedules.

Easy installation
Replace any thermostatic radiator knob in no time with the Hombli Smart Radiator Thermostat. Simply unscrew the fixing of your current thermostat knob and affix the Hombli smart Radiator knob. Additional adapters for Danfoss, Caleffi, Giacomini valves are included, all compatible with most radiator types. Check if your radiator is suitable via: hombli.com/adapter

Open window and door detection
The radiator knob automatically detects if the temperature suddenly drops rapidly due to an open window or door, and will then temporarily stop heating to avoid wasting energy. You can activate this function for free in the app, and thereby automatically save money on your heating costs.

Insight into your consumption
In the app, you can see the set and actual temperature in your home in a clear graph. This graph also shows how many minutes the heating has been on per hour. This allows you to know exactly when you are heating unnecessarily and how much you could save by turning down the temperature. You can also see per day, week, month how often the heating has been on in total, giving you direct insight into the total consumption of your heating.

"Hey Google, lower the temperature in the living room"
This smart radiator thermostat works seamlessly with Amazon Alexa, Google Assistant and Siri Shortcuts for hands-free voice control. Use your voice to turn off the heating when you go to bed early and effortlessly save energy by heating your home for a shorter period.

Long battery life
Thanks to Bluetooth Low Energy technology, the two included AA batteries last up to one and a half year. Because the radiator buttons are connected to the internet via the Hombli Bluetooth Bridge, you can control them anywhere and anytime via the Hombli app.
