Smart heating control

Control heating cycles with ease and save energy

You’re heading home in winter after a day at work: You’re looking forward to a cosy evening with a nice cup of tea and a good book in a comfortably warm living room. But when you open the door, you are greeted by icy cold air because you forgot to turn on the heating in the morning. Make it easy for yourself – true to the motto ‘Made simple’. With our smart home heating control, you can set up various heating scenarios; but you can also change the settings spontaneously from anywhere. With these automated heating cycles, you can easily save a lot of energy.

WLAN heating control

always the ideal comfort temperature

Too warm, too cold – if you are constantly adjusting the heating because you can never achieve the right temperature, then it’s time for smart radiator thermostats. You can then set your preferred comfort temperature for every room in your home – the living room, bedroom or the children’s room. And you can set it for specific times: The temperature in the living room should be a cosy 24 degrees when you get home from work.

Smart thermostats

a symbiosis of comfort and energy efficiency

With smart heating, you not only gain a high degree of comfort: By setting heating cycles, you also reduce your heating costs. An energy saving of up to 30 percent is possible when you switch from manual control.

This is achieved through more efficient heating; for example:

  • The temperature is automatically reduced when the window is opened.
  • When a set temperature is reached, the heating switches off.
  • The temperature is automatically lowered when you’re not at home.

This makes a positive contribution to your ecological footprint and to your personal well-being.

Installation with central control unit

the easy way to WLAN-controlled heating

Retrofitting your heating control with WLAN is not complicated. You merely have to replace your existing radiator thermostat with the new smart thermostat. To turn your heating control into a WLAN heating control system that can be used to operate the smart thermostats, a control centre is needed. This control centre establishes the connection to your network. A clever and practical solution: Hama supplies the central control unit with the smart thermostats. In this way, the smart home radiator thermostats can be installed within minutes. To use the individual thermostats, you need the central control unit from the Hama heating control set. Other Smart Home radiator thermostats can be made familiar with the central control unit at the touch of a button. With the included adapters, the radiator controllers will fit all common radiator valves, such as Danfoss RA, RAV, Caleffi and Giacomini.

Can be expanded as required

from smart heating control to the complete smart home

The starter set comprises the central control unit and two heating controllers. It can be expanded to include any number of thermostats – you probably want to integrate more than two radiators into your smart home. All Hama Smart Home products can be operated using the Hama Smart Home app, and can be connected with one another. If you already have smart home products from a different manufacturer and they are compatible with Amazon Alexa and Google Assistant, they too can be combined using the voice assistants.

Intuitive control by app and using your voice

While sitting on the sofa, simply tell your heating to switch on; or tell it to heat up the room by an extra one degree. The heating can be controlled by voice using Amazon Alexa and Google Assistant. In the same way, you can change the settings spontaneously using the app – including remotely. For example, you’re at a Christmas market and are frozen to the bone; you tell your heating to heat the living room to a warm 25°C.

Smart and simple

The smart heating controllers can be operated, as usual, using a knob. The LED display only goes on when you turn the knob. The installation looks stylish; the thermostat blends in harmoniously with the home design.

‘Away’ mode for holidays, etc.

What should you do with the heating when you’re on a skiing holiday and want to prevent the temperature in your home from becoming too low? Simply activate the ‘Away’ mode, and the temperature in your home is kept at a constant 16 degrees. This prevents frozen pipes, for example, and still saves heating costs.

Good news:

All Hama Smart Home products can now be controlled not only with Alexa and the Google Assistant, but also with the voice assistant Siri.

1 Create a scene

The Siri Shortcuts function enables the control of smart scenes that first have to be created. For this purpose, create a scene in the usual way that you want to activate with Siri. The existing process remains unchanged.

2 Open Siri Shortcuts

In the app The overview page displays all set-up scenes. You will find the new ‘Siri Shortcut’ button in the lower right-hand area. Tap the button.

3 Select the scene you want

A page opens, on which you can add your scenes to a Siri Shortcut. To do so, press the plus sign next to the relevant scene.

4 Create a shortcut

You can now create the shortcut. To do so, enter the wording for the command that is to be used to start this scene. If, for example, you have created a scene for a film night and would like to add it to the Siri Shortcuts, a suitable command would be ‘Start the film night’. Once you have tapped ‘Add to Siri’, you can then simply say to Siri, ‘Hey Siri, start the film night’. Siri will then run the ‘Film night’ scene from the Hama Smart Home app.

Additional tip: To control individual devices with Siri, simply create short scenes that are responsible only for switching on, switching off or switching over the individual device, and add them to Siri. ‘Fan on’, ‘Light off’, ‘Hey Siri, see to the light’ – there are no limits to your imagination!

Create scenes and automations

Get maximum convenience out of your smart products by creating scenes and automations.

Our WLAN heating control offers entirely different uses and functions if you connect it with other smart home products or set particular scenes. This is very easy to do with our app. Simple everyday manual actions can be perfectly automated with smart home systems.

Scenes and automations make your everyday life so much more pleasant and convenient:


make life easier

‘Automatically adjust temperature’ scenario: Adjust your heating control to your daily schedule: Have the temperature in your home automatically raised to 23 degrees in the morning, and lowered to 17 degrees at bedtime. Smart heating control makes these automatic heating cycles possible. You can set up your heating scenarios to suit your daily routine, and in this way, save energy and reduce heating costs.


in combination with other products

Combination with a door/window contact: If you have a WLAN window contact on your window, you can connect it to the smart thermostat. As soon as you open the window or patio door, the heating switches off. In this way, energy does not escape out of the window – the environment and your wallet will thank you.


Everyone is focusing on heating costs at the moment. With geofencing, you can control your smart heating in an even smarter and cost-saving way: all you need is the location function of your smartphone to switch the heating on and off if you are within a radius that you define (at least 100 m) of your property when entering or leaving.

  • Set the radiator thermostats to 17°C when you leave so that rooms are not being unnecessarily heated when nobody is home.
  • When you leave work, set the thermostats at home to 21°C so that it's warm when you get home.

Test results


Winner 2021

"The WORLD SMART HOME AWARD goes to the WiFi Heating Control (176593) because it convinced the jury especially with its easy installation and good usability."

Haus & Garten Test

Very good (1.3)

"The Hama thermostat does what it is supposed to do, the operation via the dial is convincing. The temperature accuracy is good and there is also no reason for criticism in the app setup."


Price/Performance: outstanding

"Hama has made a good decision by making their smart home system usable without a hub and using WLAN as the control protocol. For beginners - who really only use a few smart devices or want to slowly get to grips with the topic - a great option. These models are a great example of this. In any case, full points are also awarded for the app. It is clear, intuitive and leaves nothing to be desired. Above all, the fact that there are small sub-apps for each product and that you can combine the functions in many ways through scenes and automations is a delight. I am also convinced of the quality of the individual components. Hama offers really great products at the usual low price that are more than worth a look. It's hard to find a simpler and cheaper way to start your own smart home. So: grab it, test it, enjoy it."
