A WLAN thermostat adapts to our everyday life, learns from usage patterns and slowly heats up to save energy, even before we are at home. For many people, smart heating control is the reason for entering the world of the smart home. We have made a test comparison of the current offer and clarify what the best heating control should offer.

Smart heating control. Do you need that?

As with so many things: if you don't have it, you don't miss it, once you have it, you don't want to give it up. Smart heating control is something like this. A smart heating control system can make you a little happy at the latest when the additional payment for additional costs is significantly lower or you return to a warm apartment after your autumn vacation. Before we take a closer look at the different heating systems, let's take a look at the advantages of smart heating control.

The advantages of smart heating control

Enjoy comfort

Most of those who are interested in smart heating control have the comfort gain in mind. Getting into a preheated apartment in the evening, even if the return times vary, is tempting. Many smart thermostats can now also be controlled using a voice assistant, so that you don't even have to move off the couch when you've just made yourself comfortable. In conjunction with a smart home system, the smart heating control can also be coupled with other devices. Then the apartment welcomes you not only with warmth, but also with the right lighting and music for the end of the day. Many smart heating controls also learn from the behavior of the occupant, so that the WLAN thermostats know exactly when their use is needed.

save money

Point two on the list of benefits: saving money. Smart heating control is primarily a gain in convenience, but the cost savings should not be underestimated either. The app-controlled and automated heating thermostats ensure, for example, that children cannot let the heating run unnoticed until it stops. Suppliers of smart heating systems state that they save about 30 percent of heating costs or energy. Even if it were only half, buying a smart heating control would pay off in the long run. Why do smart radiator thermostats bring so much energy savings? These are the reasons:

  • The WLAN thermostats heat up slowly before we get home - this avoids costly boost heating.
  • "Open window detection" switches the thermostat down when ventilation is in progress.
  • The heating only runs in the rooms that we use, at the times when we live in it.
  • If the sprout turns on the heating generously, the heating thermostat sends us a push message. At the latest when the next automated time switch is planned, the smart heating control will bring the thermostat back down to the set value. Some smart thermostats also offer child lock, making manual switching difficult.
  • When we go on vacation, it cannot happen that we accidentally leave the heating on. Even if we forget to activate vacation mode, the WiFi thermostat can be switched off from anywhere.

Buying advice: The most important criteria for smart heating control

Smart home system or isolated solution

Whoever If you want to bring a smart heating control into your home, the first question is whether the system should be self-contained or connectable to other smart devices. For example, if you want to operate the lighting control, music control and heating control with an app and link them together in scenes, it is worth choosing an open smart home system. Examples: Magenta SmartHome (Telekom) or Bosch Smart Home.

The alternative to this are isolated solutions that are self-contained, such as tado ° or Netatmo. However, these "closed" solutions are often still compatible with linkage platforms such as Amazon Alexa, IFTTT or Apple HomeKit, so that they can also be controlled by voice or connected to compatible WLAN devices.

An isolated solution can therefore allow the construction of a sophisticated home automation system, but for smart home beginners with expansion ambitions, it is still recommended to buy a heating controller that is part of a smart home system. In our Wi-Fi thermostats comparison 2019, we have identified what type of heating control it is.

Note: Both the smart home systems and the island solutions couple the radiator thermostats to the smartphone via a system control center that is connected to the WLAN router. The control centers are usually included in the starter packages. Exception: Eve Thermo uses Bluetooth and uses Apple TV or iPad as the control center.

Window open detection

A window open detection is integrated in almost every smart heating control. Means: If a window opens, the WLAN thermostat detects the drop in temperature and lowers the target temperature so that the heating does not heat up against it like crazy. In many smart home systems, window-open detection is supplemented by a smart window contact. The window sensor then gives the command directly to the heating control that an open window will lead to a drop in temperature, which will then be compensated accordingly.

Geo-fencing

Some smart heating controls have the ability to tell from a smartphone's GPS data whether a family member is moving towards home. If this is the case, the WLAN thermostats heat up slowly and automatically ensure a warm reception. If the last person leaves the house, the radiator thermostats automatically switch to absence mode.

Display ad

If you already have a smart heating control, it is also practical if you can briefly read on the display what set temperature is set or how many degrees Celsius it currently has in the apartment. That is why it is best to pay attention to the legibility and size of the display when buying WLAN thermostats. At best, it is an e-paper display that shows the current temperature continuously. In most cases, manufacturers still work with LCD displays, which usually go into sleep mode after a few seconds. Here you have to press the button briefly to activate the display. The background is the optimization of the energy consumption of the heating thermostat.

Temperature deviation

The radiator thermostat measures the current temperature directly on the heater. The measured temperature is of course not representative of the whole room. To get a better heating result, you can set a temperature deviation in the app in many smart heating controls, the so-called offset value. This temperature deviation is usually set at the factory to two degrees. That means: If the heating control measures the target temperature of 20 degrees Celsius on the thermostat, it heats up to 22 degrees Celsius so that the entire room has an average temperature of 20 degrees Celsius. If you can afford smart heating control via WLAN thermostats, then this function should be included at best.

Voice assistant

In recent years, there has been a clear trend towards voice control. The “hands-free” method for controlling the smart home is of course also perfect for heating. Therefore, almost all manufacturers have upgraded and ensure a connection to the Amazon Alexa, Google Assistant or Apple HomeKit for heating control. The latter two are less common, so you have to pay special attention to whether the selected system is compatible with the desired language assistant.

Retrofitting underfloor heating smart?

Underfloor heating can also be smartly upgraded. Nevertheless, you have to be aware that not all smart home systems provide the appropriate technology. So when it comes to smart floor control, it is particularly important to take a close look at whether there is a possibility of retrofitting. The Controme heating control is particularly interesting for the app-based control of the underfloor heating. With additional sensors on the heating circuit returns, the system receives feedback about the actual floor temperature in each room. According to Controme, the overshoot and undershoot of room temperatures can be almost completely eliminated, which is often a major problem, especially with underfloor heating.

Heating controls 2019 in the test overview

tado ° heating control

tado ° inevitably comes across when you are looking for a smart heating control. The company specialized in heating control via app right from the start of the smart home movement and has been refining its system ever since. Accordingly, there are many tests, and it is not uncommon for them to be very positive. What tado ° puts in the foreground is the automated control of the heating via geofencing: if we leave the house, the heating goes down, we come back, it goes up. tado ° has tinkered around with it in order to develop an energy-saving solution for retrieving the GPS data via the smartphone. Tado ° also includes the current weather conditions in the heating behavior.

The tado ° radiator thermostat is available from Amazon for around 70 euros.

Photo: tado °

Of course, fixed schedules for every day of the week can also be set in the app. The tado ° principle is: have as little as possible to do with the heating control and still enjoy the best possible temperature. Although tado ° is a closed system, it can be connected to other smart devices via Amazon Alexa, Google Assistant and Apple HomeKit. IFTTT applets (if-then automations) are also available for tado °. This enables the heating control to be coupled with Philips Hue or Google Sheets, for example.

Smart Home System: No.

Window open detection: Yes

Geo-fencing: yes

Display: LED

Temperature deviation (offset value): Yes

Underfloor heating compatible: Yes

Voice Assistant: Yes

Compatible with: Google Assistant, Amazon Alexa, Apple HomeKit, IFTTT

Test voices for tado ° heating control:

After the test, ComputerBild says: “The heating thermostat convinced us! The simple installation and operation is exemplary, which is how electronic heating thermostats are really fun.”

Giga also says: "The main advantage of tado ° is the sophisticated" Away "mode, which automatically throttles an algorithm and weather data using GPS data from the smartphone and heats it up again in good time."

Netatmo heating control

Just like the Tado ° thermotates, the Netatmo thermotates impress with a chic look that you are not used to from heating thermostats. The smart Netatmo radiator thermostat can also be "pretted up" with a colored sticker. Unlike Tado °, Netatmo does not offer GPS-based heating. Here you can only switch to different modes manually using the app or voice control or let the heating control run according to fixed plans that can be set in an appealing Netatmo app.

Thanks to the HomeKit connection, the Netatmo thermostat can also be connected in scenes with many different HomeKit-compatible devices. It is somewhat incomprehensible that the other smart home devices from Netatmo, such as the weather station or the presence internal security camera, cannot be controlled with the same Netatmo app. IFTTT applets must be used to interconnect the individual devices. Incidentally, either a smart wall thermostat or a separate gateway serves as the control center.

Smart Home System: No.

Window open detection: Yes

Geo-fencing: No.

Display: LED lights

Temperature deviation: yes

Underfloor heating compatible: Yes

Test voices for Netatmo heating control:

Appgefahren.de says: "The Netatmo radiator thermostats also do their job excellently, especially the design and the app with the great schedules are convincing." (Test score: 8.5 / 10)

Techtest.org says: "Netatmo has put together an excellent smart heating solution that can score with its beautiful design and good app."

Elgato Eve heating control

Since the new version of the Elgato Eve thermostat, which was released in 2017, Elgato Eve has also been a competitive smart heating control. You can now manually adjust the temperature on the thermostat and read the temperature (if you activate the display). Because with all the "smartness" you just want to adjust the temperature when you walk by and not use the app. In contrast to most radiator thermostats, the manual temperature settings for the Eve Thermo are made using a touch control panel (0.5 ° C per tip). Current testers find, however, that this reacts somewhat slowly to inputs. In terms of feel, we like the twist variant, as found, for example, at Netatmo or Tado °, much better.

The control center of the Elgato Eve heating control is an Apple TV or iPad (with app). Anyone who already has one of these in-house does not need to invest in a control center. Another advantage over Netatmo: The available Eve Smart Home devices can be easily linked with each other using the Eve for HomeKit app.

Test votes for Elgato Eve Thermo heating control:

Macwelt.de sums up after the test: "For iPhone owners, Elgato's smart heating thermostat is an exciting convenience option for the home."

Computerbild says to Elgato Eve Thermo: “In the practical test, installation and operation worked right away; the range of functions of the app was also convincing."

Controme heating control

With Controme, a mini server acts as the control center of a comprehensive overall concept for smart heating control. The German company has given its smart thermostats so much intelligence that the heating control adapts itself in a self-learning way to the usage behavior of the owner. Just like tado °, here too - keyword geofencing - an environment can be defined. If we leave the defined zone, the smart thermostat switches down, if we enter it, the thermostat starts up. The synchronization with the weather data is also possible, so that the smart heating control can react quickly to a cold incident. Compatibility with Amazon Echo, Google Home and Apple HomeKit was expanded at the end of 2018, which is why we have already included them in the heating control comparison overview.

Controme is the only system that also integrates a user management system that allows the creation of almost any number of user accesses with freely definable rights. With Controme, the radio range can also be expanded as required by additional mini servers. This makes it possible to fully equip even large buildings with the smart Controme control.

Test voices for Controme heating control:

blogjensihnow.de reports: “Almost exactly a year ago, I reported my decision to convert my underfloor heating to Controme for the first time. So far I have not regretted this step and have participated in pretty much every update / upgrade from Controme. […]. This slogan is used by Controme and certainly applies."

Eurotronics Comet DECT heating control

Eurotronic Comet is only a solution for smart home beginners who have an AVM FRITZ! Box with Dect as an Internet router at home. The router serves as a control center for smart heating control with Eurotronics. The radiator thermostat offers essentially the same functions as the AVM radiator thermostat itself, which is called FRITZ! DECT 301. All automations for the radiator thermostat can be created using the FRITZ! Box web browser under the Smart Home heading. New settings are only transferred every 15 minutes. This should make the radiator thermostat work as energy-saving as possible. A child lock ensures that children and unauthorized persons cannot make any changes.

Intelligent links with other FRITZ! Box-compatible smart home products, such as the WLAN connector FRITZ! DECT 200 or the Magenta motion detector, are also possible. So while Eurotronics does not offer its own smart home system, the heating control can be easily integrated into the FRITZ! Box smart home. The advantage to the AVM thermostats is that Comet DECT is a tick cheaper. The FRITZ! DECT 301 has an ePaper display that can be read at any time.

Tip: If you don't want to control the heating thermostats via the original FRITZ! Box app because they don't specialize in smart homes, you can also look at the fritch, Muzzley or SmartFranz apps. By the way, voice assistants are not supported by AVM, but there is an unofficial skill for Amazon Alexa, so that the Comet DECT thermostat can also be addressed.

Smart Home System: No.

Window open detection: Yes

Geo-Fencing: No (only via IFTTT)

Display: LCD display (turns off when not in use)

Test votes for Eurotronics Comet DECT heating control

Smart-home.one writes in the field report: "Compared to the cheap, automatic heating controllers from the hardware store, the Comet DECT is a high-quality, and above all quiet heating controller."

Einbruchschutz-und-alarmanlagen.de sums up after the practical test: "The heating thermostat convinced us! The simple installation and operation is exemplary, which is how electronic heating thermostats are really fun.”

Magenta SmartHome heating control

Known from various advertising media, the Magenta SmartHome offers a very flexible, expandable smart home system. The comprehensive system offers different starter sets for every taste, each of which contains a control center called "Qivicon Homebase". The Qivicon homebase supports not just one, but four radio standards: Homematic, Homematic IP, ZigBee and DECT ULE. This means that the system can be expanded and connected to many, including external, smart home devices, including various heating thermostats.

Heizkörperthermostat
Heizkörperthermostat

The radiator thermostat from Telekom costs around 50 euros.

The manufacturer's Magenta SmartHome Thermostat can be controlled both by app and by voice assistant. For window open detection, the thermostat is connected to a window contact of, for example, magenta or eQ3. Like all smart thermostats in comparison, you can pre-program various time switches in the app. The Magenta SmartHome heating thermostat is also equipped with a geofencing function, but testers complain that it only works when you return to the house and not when you leave. Updates to the app can of course eradicate such errors at any time, if you decide to buy the Magenta SmartHome heating control, you should test this function first (at least if it is important for your own needs).

Tip: Alternatively, you can also connect the Netatmo thermostat to the Telekom Magenta Qivicon base station or the eQ3 Homematic IP heating thermostat, which we will introduce below in our smart heating control comparison 2019. All you need for the smart home experience is the Qivicon base station and a contract with the Telekom for the associated Smart Home app (as is always the case with Telekom). If these requirements are met, the magenta system can be designed with smart home devices and the best smart heating control. The compatibility list can be found here in the overview.

Magenta SmartHome heating control

Smart Home System: Yes, Qivicon base station

Window open detection: Yes, in conjunction with an additional window contact

Geo-fencing: yes (currently only arrival at home is registered)

Display: LCD display

Temperature deviation (off-set value): Yes

Underfloor heating compatible: No.

Voice Assistant: Yes

Compatible with: Amazon Alexa, Google Assistant, Magenta SmartHome System and all Qivicon-compatible products

Test voices for Magenta SmartHome heating control:

After the test, Housecontrollers says: "The strength of the Magenta Smart Home System lies […] in the other possible applications that a Smart Home system offers."

Techtest.org sums up in the experience report: "A base station that works with HomeMatic modules, Philips, Osram, Netatmo etc. is simply great compared to many other smart home systems that are self-contained […]."

Bosch Smart Home heating control

Similar to the Magenta SmartHome system, the control center of the Bosch Smart Home System is equipped with numerous radio standards in order to be as accessible as possible for many non-manufacturer Smart Home devices. However, one still has to wait for the expansion of the partner network. So far there is not much more product compatibility than we have listed below. However, the components that Bosch offers are mature and of high quality, so that you can accept this loss at least as a smart home beginner. If you install the Bosch Smart Home heating control, it takes a while for the system to really prove itself. The reason for this is that you cannot set an offset value. So you always have to rethink something. If it is to be 20 degrees Celsius in the middle of the room, it is probably necessary to set it to 22 degrees Celsius on the heating thermostat or by app. But once all automations have been defined accordingly, this fact no longer plays a major role.

The display should have been a little bigger. Depending on the viewing angle, you have to twist a little to be able to read the current target temperature. Like the Elgato Eve Thermo Thermostat, the temperature is not adjusted manually by turning, but by pressing a button. The thermostat has three buttons that can be used to quickly control the status without using the app. Google Assistant and Siri fans are still looking into the tube at Bosch. Only the Amazon Echo or Alexa speaks with the smart heating control.

Test votes for Bosch Smart Home heating control:

Blog.notebooksbilliger.de writes: “The system ran stable and inconspicuous during the test period, the setup was quick and easy. Using the app, which is reduced to the bare minimum, is also very easy to use.”

Homematic IP heating control

Homematic IP is a smart home radio standard, but also a smart home system from eQ3, which logically communicates via this radio standard. Various starter sets allow you to quickly get into the smart home: smart light control, burglar protection and of course smart heating control. To use the Homematic IP heating thermostat, you need either the appropriate Homematic IP Access Point or the Magenta SmartHome control center (or another control center, insofar as it also supports Homematic IP). With more than 80 available components, the system can be expanded almost arbitrarily. The Homematic IP Radiator Thermostat cannot score with the optics, but with an easy-to-read display and up to 13 switching times per day, which can be specified in the app. In many systems, the end of eight switching points is already complete, which of course is usually sufficient for everyday use.

After the test, PC-Welt says: "Homematic IP is not a handicraft solution and does not require any special training, but can be operated intuitively."

Techtest.org confirms: "[The Homematic IP Thermostats] fit into my everyday life very well due to their simple controls and the detailed schedule that can be created for them."

Honeywell Evohome heating control

What is particularly striking about the Honeywell Evohome heating thermostat is the LCD display, which can also be fixed upright using the display holder. This could be an advantage for people with restricted mobility, for example, but it is also a general plus in terms of comfort - optically, of course, one can argue about it. The rotary wheel allows the temperature to be adjusted spontaneously, just as with the smartphone app. The Evohome thermostat is self-learning so that it automatically makes the correct settings after a few days of observation. Of course, you can also pre-empt the thermostat and pre-program the desired heating times.

Evohome also offers a smart home system that can be controlled via the central gateway with a touch display. What has succeeded well here is that the control center is at the same time an operating panel via which up to twelve zones can be individually configured with temperature and time settings. So you don't necessarily have to use the app. Evohome also offers water detectors, surveillance cameras and alarm systems.

Nerd-o-mania says: “After 3 months of continuous operation, I can say that the system is maintenance-free and reliable. The thermostats have not lost contact with the base station, and there have been no abnormalities. The battery level displayed is still 100% […]."

Tchgdns.de says after a three-year endurance test: "If you ignore the price, I can only recommend the Evohome." (Note from the Haus.de editorial team: the price is now in the lower average in comparison)

Tip for retrofitting smart radiator thermostats

If you bring a smart heating control into your home that is implemented with WLAN radiator thermostats, you should definitely keep your old thermostats. For one thing, it's always good to have a back-up, should a smart thermostat give up (for example in very damp bathrooms). Otherwise, in the worst case, you can no longer shut down the fully turned on heater. On the other hand, it also applies to tenants that the apartment must be restored to its original condition when moving out. And of course you don't want to leave your smart thermostats to the next tenant, just stow the smart heating control in your backpack and use it in your next apartment. To do this, the old thermostats must then be screwed on again. Incidentally, no craftsman is required to install a smart heating control. Almost all manufacturers offer video instructions for installation.

Conclusion: what is the best smart heating control?

As is so often the case with smart homes: the decision for a system depends on your own needs. If you don't necessarily want to connect your heating control with a smart home system, you can do it well with stand-alone solutions such as tado °, Controme and Netatmo. Both the optics of the thermostats and the functions of the app are right here. The Elgato Eve Smart Home series is particularly interesting for Apple users. In addition to the Elgato Eve Thermo, the system can already be linked to other sensors. However, if you want to achieve a round smart home experience in the long term, you can better opt for a smart heating control that can be linked to a large ecosystem and is often a lot cheaper than the design variants mentioned.

Smart heating control - recommendation for Apple users

As an iPhone / iPad user, you can already set up your smart home system very well using the Apple HomeKit. This means that essentially all smart thermostats with Apple HomeKit compatibility can be used.

Smart heating control - recommendation for users of underfloor heating

Fans of voice control via Google Assistant or Amazon Alexa can of course also use the voice assistant as the linchpin for the smart home and use it to link the smart heating control with other devices.

Smart heating control - recommendation for smart home beginners with expansion ambitions

If you want to build a comprehensive smart home system, you should make sure that the selected system covers all desired areas of application (smart heating control, burglar protection, light control …).

How to save money and energy with smart heating control

Scientists have calculated: A smart heating control can significantly reduce heating costs. Twice as good: If you intelligently network your home, you will even receive government funding.

On average, heating causes almost 70 percent of the total energy consumption of a household - and the costs are slipping: According to a study by Co2Online, private consumers in Germany spend around twelve euros on heating costs per square meter of living space annually. Residents of an apartment with 70 square meters therefore pay around 840 euros a year. In a single-family house with 120 square meters, an average of around 1440 euros a year.

Misconduct can be expensive

A modern, well-maintained boiler and an energy-saving circulation pump help to reduce expenses. "But it is often the behavior of the residents that unnecessarily drive up energy costs, " says Matthias Kersken, a research assistant at the Fraunhofer Institute for Building Physics IBP. After all, some people simply leave the heating on even when they are away or forget to close the roller shutters on cold nights. This is where smart home technology comes in and takes on annoying but meaningful tasks for the residents.

Smart heating control pays off

Studies at the Fraunhofer IBP show that smart home solutions can reduce heating costs for an average household by up to 10-15 percent. However, if you want to save as much as possible, you must also use all options: automatic shutter closing, individual room temperature control and heating shutdown with the window open. "In special cases, for example if the heating bill does not contain domestic hot water, the savings can even be up to 25 percent, " says Kersken. However, the expert advises, you should also pay attention to the power consumption of the smart home systems. This can vary depending on the manufacturer.

State subsidy for smart home upgrade

If you want to network your building services, you can apply for financial help from the state: For example, KfW programs for “age-appropriate renovation” are possible. Measures that remove barriers are funded. This also includes the automatic control of shutters, heating and light. By the way, the state funds also get young people who want to increase their living comfort at an early stage.
