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.  

Ideal for district or block heating 
Does your home or office use district or block heating? With these smart radiator knobs, you can easily set the temperature without having to manually open and close the knobs. The smart radiator knobs are also handy in combination with your own central heating with the (smart) thermostat so you can adjust the temperature per room.  

Open window 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 so as 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, and month how often the heating has been on in total, giving you direct insight into the total consumption of your heating.  

Long battery life 
Thanks to Bluetooth Low Energy technology, the two included AA batteries last up to one and a half years. 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.  

Control everything in one handy app 
All Hombli devices can be added in one handy app, allowing them to work together smartly. For example, automatically turn down the heating, turn off Hombli smart lights, and turn on the Hombli Indoor and Outdoor security camera the moment you leave your home using a Geofencing scenario. Alternatively, place contact sensors on a window or door and set the heating to turn off automatically when they are opened.  

Controlling all radiators simultaneously  
Do you have several radiators in a room? Then you can easily link all the smart radiator thermostats together in the app. After linking, the settings will automatically change on all linked radiator thermostats. So, if you increase the temperature on one radiator knob by turning the knob, the temperature will be adjusted on all linked knobs. 

"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. 

Modern and robust design 
The Hombli Smart Radiator Thermostat has a modern and compact design, so it fits into any interior, even if space is tight. The housing has a metal mounting ring for extra-strong installation. You can control the temperature via the app, or by turning the knob on the radiator thermostat. The clear display shows the temperature after you change it or after you press the button.   

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, and Giacomini valves are included which are compatible with most radiator types. Check if your radiator is suitable via: hombli.com/adapter  

Protect radiators against limescale 
If the radiator is left off for a long time, scale and limescale can build up on the inside of the pipes and inside the radiator. This causes the radiator to become less efficient over time. The Smart Radiator has a built-in function to prevent this. It automatically opens the tap for 30 seconds every two weeks. This ensures that during summer that the radiator is still working to ensure optimal usage once winter arrives.

Goed met app, slecht met Google home

De Hombli app werkt redelijk goed.
De samenwerking met Google Assistant is beroerd.
Je kan de huidige temperatuur en de ingestelde temperatuur wel opvragen maar je kan de thermostaat niet aan/uit zetten.
Dus de kids moeten alsnog aan mij vragen om met de app de verwarming aan te doen..
Beetje jammer.

Drama

Al best een tijd bezig maar na een dag installeren nog steeds geen goede temperatuur en kan buitenshuis nog steeds geen verbinding maken met de Smart Bridge.
En als jullie dan toch een handleiding in het doosje doen doen er dan een wat fatsoenlijke uitgebreide in, dit is drama

Prima!

De producten werden zeer vlot geleverd en hoewel nog niet geïnstalleerd, kan ik zeggen dat ze er zeer fraai uitzien.

Stadsverwarming

Hoe werkt dit systeem i.v.m. stadsverwarming normaal stuurt de thermostaat een klep aan in de aanvoer leiding. Hoe werkt dat als ik dit systeem gebruik? Vervalt mijn oude thermostaat dan?

Hombli

Hallo,

Bedankt voor je vraag over de Hombli Smart Bluetooth Radiator Thermostat Expansion Pack 2 + 1 in combinatie met stadsverwarming.

Bij stadsverwarming is er meestal geen individuele cv-ketel, maar wordt de warmte centraal geleverd. De traditionele thermostaat stuurt dan vaak een klep aan in de aanvoerleiding om de warmte te regelen. De Hombli Smart Radiator Thermostaat werkt echter op de radiatorkranen zelf. Dit betekent dat je per radiator de temperatuur kunt regelen via de Hombli app, zonder dat je de centrale aanvoer hoeft te beïnvloeden.

Wat gebeurt er met je oude thermostaat?
Als je overstapt op de Hombli thermostaatknoppen, dan gebruik je de oude thermostaat niet meer om de temperatuur per ruimte te regelen. In plaats daarvan stel je de gewenste temperatuur per radiator in via de app of handmatig op de knop zelf. De centrale aanvoer van warmte blijft echter actief zolang het verwarmingssysteem aanstaat.

Voor meer informatie kun je ook onze handleiding raadplegen via https://support.hombli.com/kb/257194

Als je hulp nodig hebt bij de installatie of twijfelt over de compatibiliteit met jouw systeem, neem dan gerust contact op via support@hombli.com – we helpen je graag verder!

Ik heb zes radiateurs over twee verdiepingen in mijn huis.
Kan ik dan met een enkele starterskit en 4 losse thermostaatknoppen, dus totaal zes hiermee alle radiateurs aansturen?

Gr.Maarten

Hombli

Hallo Diana,
Bedankt voor je vraag! Ja, dat klopt: met één starterskit (die een Bluetooth-gateway en één thermostaatknop bevat) en vier extra losse thermostaatknoppen (zoals in het 2+1 uitbreidingspakket), kun je in totaal zes radiatoren aansturen — ook als deze verdeeld zijn over twee verdiepingen.

Belangrijk is wel dat de Bluetooth-gateway zich op een centrale plek bevindt, zodat hij binnen bereik is van alle thermostaatknoppen. De maximale afstand tussen de gateway en de knoppen is ongeveer 10 meter (afhankelijk van muren en andere obstakels).

Mocht je hulp willen bij het instellen of positioneren van de gateway, dan helpen we je graag verder via support@hombli.com.

Kind regards,
Hombli-Team

Dear Hombli,
Is it possible to connect these radiator thermostats with all systems?
We have a central Honeywell Home system but are not satisfied with it, it does not want to connect since we have a Heat pump (Cullen motor)
Are your thermostats automatically visible on the Honeywell home central screen, or do we need another hub to buy for your thermostats ??
please hope you can answer this,
Thanks, Ineke Siersema

Hombli

Hallo Ineke,
Thank you for your question!
The Hombli Smart Bluetooth Radiator Thermostat (Expansion Pack 2+1) is designed to work with the Hombli Smart Radiator Thermostat Starter Kit, which includes the required Bluetooth-WiFi Bridge. This bridge is essential for connecting the thermostats to the Hombli app and for remote control via your smartphone.

Unfortunately, our thermostats are not directly compatible with the Honeywell Home system, and they will not automatically appear on the Honeywell central screen. If you wish to use Hombli thermostats, you would need to use the Hombli app and the Hombli Bluetooth-WiFi Bridge. Integration with other systems like Honeywell is currently not supported.

If you're using a heat pump system, it's important to ensure that your radiators have thermostatic radiator valves (TRVs), as the Hombli thermostats are designed to replace those.

You can find more details about the product and compatibility here: 👉 https://www.hombli.com/adapter

If you need help determining compatibility with your specific setup, feel free to contact us at support@hombli.com with more details about your heating system.

Kind regards,
Hombli-Team

Ik ben op zoek naar een slimme radiatorknop die de thermostaat laat aanslaan. Begrijp ik het goed dat de Hombli radiatorknop de temperatuur in een vertrek regelt, maar het alleen doet als de thermostaat aanslaat. Ik lees nergens dat de Hombli radiatorknop de thermostaat aanstuurt.
Ik wil graag een systeem waarbij de verwarming aanslaat als de temp op een radiatorknop te laag wordt.

Klopt mijn redenatie?

Ik hoor graag.

Hombli

Hallo,
Bedankt voor je duidelijke vraag! Je redenatie klopt inderdaad: de Hombli Smart Radiatorknop regelt alleen de radiator in de ruimte waar hij is geïnstalleerd, en stuurt niet de centrale thermostaat aan. Dat betekent dat de verwarming pas aanslaat als de centrale thermostaat dat toestaat — de Hombli knop kan dit niet zelfstandig doen.

Wat je zoekt is een systeem waarbij de verwarming automatisch inschakelt zodra de temperatuur in een specifieke kamer te laag wordt. De Hombli knop kan dit niet direct, tenzij de centrale thermostaat al actief is. Een mogelijke oplossing is om de Hombli knop te combineren met een slimme thermostaat zoals de Google Nest Thermostaat, en beide apparaten te koppelen via Google Home. Zo kun je de temperatuur in verschillende ruimtes beheren via één app. Maar ook dan blijft de Nest thermostaat leidend: als die de verwarming niet inschakelt, zal de Hombli knop geen warmte krijgen.

Laat me weten als je hulp nodig hebt bij het kiezen van een geschikte combinatie of installatie!

Kind regards,
