Best HomeKit & Matter Smart Radiator Thermostats for Europe (2026)
Eve, Aqara, tado, Bosch, Netatmo, Meross or SwitchBot? We compare the smart radiator thermostats that really work with Apple Home in Europe, explain which ones need their own bridge, and cover the wall thermostats that switch your boiler.
Most homes in Europe are heated with hot-water radiators, and that makes the smart radiator thermostat the most useful heating upgrade you can buy. It replaces the knob on each radiator, so every room gets its own temperature and schedule, and you stop heating the bedroom all day or the spare room all week. For Apple users, the question isn't whether a thermostat works with Siri, but how it gets into the Home app: directly over Thread and Matter, or through the manufacturer's own bridge. This guide sorts that out and recommends the thermostats we would fit in our own homes this winter.
How we chose
We started from every heating product in our catalog that is sold in European Amazon stores and works with Apple Home, either natively through HomeKit or through Matter. Then we narrowed it down:
- Works in the Apple Home app. Every pick can be controlled in the Home app and by Siri. We say clearly when that needs a manufacturer bridge.
- Local and private where possible. Thread and Matter thermostats keep working on your home network when the internet or the maker's cloud is down. We favoured those.
- Fits European radiators. All the radiator thermostats here fit the common M30 × 1.5 valve thread, and most come with adapters for Danfoss and other valve types.
- Useful heating features. Schedules that run on the device, open-window detection, and support for a separate room sensor.
- Availability. Products you can buy in several EU countries, not one-off imports.
Prices change too often to be useful in an article, so we leave those to the product boxes, which show a current price where one is available.
Our top pick: Eve Thermo (5th generation)
Eve, from Munich, has made radiator thermostats for Apple Home for longer than anyone, and the 5th-generation Eve Thermo is the best one yet. It runs Matter over Thread, so you add it straight to the Home app with no bridge and no Eve account, and it keeps working locally if your internet goes down. The housing is more compact than before, with an LED display and touch controls on the device.
The free Eve app adds what the Home app can't do: schedules for working days and days off that run on the thermostat itself, comfort and eco temperatures per room, and a temperature offset so the reading matches the middle of the room rather than the spot next to the radiator. Open-window detection pauses heating when the temperature drops suddenly. It fits M30 × 1.5 valves and comes with adapters for Danfoss RA, RAV and RAVL, and it runs on two AA batteries.
What it needs: a Thread border router, which in an Apple home means a HomePod mini, a HomePod (2nd generation or later) or an Apple TV 4K with Thread. Because it's Matter, you can also share it with Google Home, Alexa or Home Assistant later.
Best for accurate room temperature: Eve Room Comfort Set
A thermostat on a radiator measures the temperature right next to a hot radiator, which is rarely what the room feels like. The Eve Room Comfort Set fixes that by pairing an Eve Thermo (4th generation, also Matter over Thread) with Eve Thermo Control, a small sensor and controller with buttons that measures the temperature where you actually sit. The thermostat then heats until that spot is warm enough. One Thermo Control can steer several Eve Thermos in the same room.
Keep in mind that linking Thermo Control to the radiator thermostats works in Apple Home only. The requirements are the same as for the Eve Thermo: a HomePod or Apple TV with Thread as your home hub. If you start with this set, you can add more Eve Thermos for the other rooms later.
Best value Matter thermostat: Aqara Radiator Thermostat W600
The W600 is the most affordable way to get a Matter-over-Thread radiator thermostat into Apple Home. It ships in Thread mode, so you scan its Matter code in the Home app and it works without an Aqara hub. It has a dial on the device, runs on two AA batteries and is very quiet.
There's a trade-off. In Matter mode you get the basics in Apple Home: current temperature, target temperature and modes. The more advanced features, such as schedules on the device, external Aqara temperature sensors and automatic window detection with Aqara sensors, only work if you switch it to Zigbee mode with an Aqara hub. You have to pick one mode or the other. For most Apple users who build schedules in the Home app, Thread mode is enough. This model isn't listed in the French Amazon store.
Best complete system: tado Smart Radiator Thermostat Starter Kit V3+
tado is one of Europe's best-known heating brands, and its V3+ system is a good choice if you want polished heating features rather than just a valve. The starter kit includes the tado Internet Bridge, which is how the thermostats get into Apple Home: you add the bridge with its HomeKit code and the thermostats appear in the Home app automatically.
The tado app has detailed heating reports, and with tado's optional paid Auto-Assist subscription it can lower the heating automatically when everyone leaves and when a window is open. Without it, those features remind you instead of acting. One thing to know: tado now also sells tado X, a separate Matter-over-Thread range. tado X and V3+ devices can't be mixed in one home, so stick to one range when you add rooms.
Best for a whole-house system: Bosch Smart Home Heating Starter Set
Bosch Smart Home is a German system that grows from heating into alarms, door and window sensors and lights. Its radiator thermostats connect to the Bosch Smart Home Controller II, which links the whole system to Apple Home. The Controller II can also act as a Matter bridge, so you can share the thermostats with other platforms. Make sure the set you buy includes the Controller II, because the thermostats don't work in Apple Home without it.
Bosch's thermostats have a clear display, open-window detection and work well with Bosch's door and window contacts, which stop heating in a room as soon as a window opens. If you want one dependable system rather than a mix of brands, it's a strong choice, especially in Germany, where it's widely sold.
Best from a French brand: Netatmo Smart Radiator Thermostat Starter Pack
Netatmo's classic radiator thermostats work with Apple Home through native HomeKit: the starter pack's relay is the bridge, and you add it to the Home app with its HomeKit code. Each room gets its own temperature, and the free Home + Control app adds schedules, open-window detection and heating reports. Netatmo's design is also one of the nicest on a radiator.
Netatmo has also launched a new Radiator Valve ORIGINAL range. Those valves need Netatmo's Thermo Hub, which brings them to Apple Home through Matter, and they don't work with the older Netatmo thermostats. If you already have Netatmo heating, stay with the classic range shown here. If you're starting fresh, check which range the listing you buy belongs to.
Budget pick with a bridge: Meross Matter Radiator Thermostat with Hub
Meross's radiator thermostat connects to a Meross hub over 433 MHz radio, not Wi-Fi or Thread, so it doesn't depend on a strong Wi-Fi signal at the radiator. The hub then brings it into Apple Home. With Meross's MSH450 Matter hub it joins as a Matter accessory. The older MSH300 and MSH400 hubs connect through HomeKit instead. Check which hub the bundle includes before you buy.
It has a display, open-window detection that pauses heating for 30 minutes, up to six heating periods per day, and comes with adapters for Danfoss and other common valves. One hub handles up to 16 thermostats, which makes it an affordable way to fit out a whole flat.
Also works with Apple Home: SwitchBot Smart Radiator Thermostat
SwitchBot's radiator thermostat is a Bluetooth device, so it needs a SwitchBot hub with Matter (Hub Mini Matter Enabled, Hub 2, Hub 3 or AI Hub) to show up in Apple Home. Check whether the combo you buy includes one. In the Home app you can switch it on and off and set the temperature. Schedules and the rest of SwitchBot's features stay in the SwitchBot app. It's most useful if you already use SwitchBot hubs, curtains or sensors.
If you have your own boiler: smart wall thermostats
Radiator thermostats only open and close the valve on each radiator. They can't tell a gas boiler to start. In a flat with central heating that's fine. If you have your own boiler, you also want a smart wall thermostat to switch it, otherwise a radiator can call for heat that never comes.
The Netatmo Smart Thermostat (designed by Philippe Starck) is our pick for most individual boilers. It works with Apple Home through native HomeKit, learns how long your home takes to heat up, and works together with Netatmo's classic radiator thermostats as one system. Netatmo has a compatibility check on its website, so check your boiler before you buy.
The Meross Matter Heating Thermostat is a wall thermostat for boilers and underfloor heating that joins Apple Home as a Matter device over Wi-Fi, with schedules and no subscription. It replaces an existing wall thermostat, so it needs wiring. If you aren't sure how your heating is wired, ask an installer.
What to know before you buy
Thread, Matter and bridges
Thread thermostats such as Eve Thermo and the Aqara W600 join Apple Home directly through Matter. They need a Thread border router: a HomePod mini, a HomePod (2nd generation or later) or an Apple TV 4K with Thread. The Wi-Fi-only 64 GB Apple TV 4K (3rd generation) has no Thread radio. Battery thermostats don't strengthen the Thread network themselves, so mains-powered Thread devices like smart plugs help in large homes. Bridge-based systems (tado, Bosch, Netatmo, Meross, SwitchBot) need their own hub plugged into your router or a socket, and that hub brings the thermostats into Apple Home.
Will it fit my radiator?
Most radiator valves in Europe use the M30 × 1.5 thread, and every thermostat here fits it. Danfoss valves are common too, especially in Scandinavia and the Netherlands, and need an adapter, which most kits include. Unscrew the old knob first and check the valve type. Most makers have a compatibility tool on their website.
Schedules in the Home app or the maker's app?
The Home app can set temperatures and run automations based on time, presence or a sensor, which covers most needs. Schedules stored on the thermostat itself, as with Eve, keep running even when your home hub is offline. Features like heating reports and boiler optimisation stay in the maker's app.

Our verdict
If you have a HomePod or Apple TV with Thread, buy the Eve Thermo (5th generation): it joins Apple Home directly, runs schedules on the device and needs no account. Add the Eve Room Comfort Set in the rooms where comfort matters most, and choose the Aqara W600 to fit out more radiators for less. Pick tado, Bosch or Netatmo if you want a complete heating system with its own app and bridge, and Meross for the lowest cost per radiator. If you heat with your own boiler, pair your radiator thermostats with a smart wall thermostat like the Netatmo Smart Thermostat.
Frequently asked questions
Do I need a home hub for a smart radiator thermostat?
For Apple Home, yes in practice. Matter-over-Thread thermostats like Eve Thermo and Aqara W600 need a HomePod mini, HomePod (2nd generation or later) or Apple TV 4K with Thread, which acts as both Thread border router and home hub. Bridge-based systems like tado, Bosch, Netatmo and Meross need their own bridge, and you need an Apple home hub for remote control and automations.
Do smart radiator thermostats fit European radiators?
Almost always. Most radiator valves in Europe use the M30 × 1.5 thread, which every thermostat in this guide fits. Danfoss valves need an adapter, and most kits include adapters for Danfoss RA, RAV and RAVL. Take off the old knob and check the valve before you buy.
Can a radiator thermostat switch on my boiler?
No. A radiator thermostat only opens and closes the valve on its radiator. If you have your own boiler, you also need a smart wall thermostat, such as the Netatmo Smart Thermostat, or a system like tado or Bosch that can control the boiler. In flats with central heating, radiator thermostats alone are enough.
Is Thread better than a bridge for radiator thermostats?
For Apple Home it's usually simpler. Thread thermostats join the Home app directly through Matter, work locally and need no manufacturer account. Bridge-based systems are also reliable and often have richer apps, but you need to keep the bridge plugged in and the thermostats only reach Apple Home through it.
Can I use Eve Thermo with Alexa or Google Home too?
Yes. The Matter versions of Eve Thermo can be shared from Apple Home with Google Home, Alexa, SmartThings or Home Assistant through the accessory's pairing settings. Each platform needs its own Matter controller with Thread. Linking Eve Thermo Control to the thermostats only works in Apple Home.
How much can smart radiator thermostats save?
It depends on your home and habits, so be wary of fixed percentages. The savings come from heating each room only when it's used, lowering the temperature at night and when you're away, and stopping heating while a window is open. Rooms you rarely use, such as a spare bedroom, are where you'll notice the difference most.
