tado and Matter: which devices work, Bridge X and setup
Yes: tado Matter support is limited to the tado X line, not V3+. The Smart Thermostat X, Smart Radiator Thermostat X and Wireless Temperature Sensor X are Matter-certified over Thread with Bluetooth commissioning, and they join Matter apps via a Bridge X or another Thread border router. Domestic hot water control is not currently available over Matter.
This guide is based on the CSA certification ledger and tado help and product pages fetched 2026-10-28, and Apple, Google, Amazon, SmartThings and Home Assistant Matter pages fetched 2026-10-20. Manufacturer claims are tado's own. Product lists and platform support can change, so check the linked pages for current details.
CSA ledger: the three Matter-certified tado X room devices
The CSA Distributed Compliance Ledger lists tado as vendor ID 4942 with three Matter-certified room devices. The CSA model page for tado shows the original part numbers RU04, VA04 and SU04, plus newer SKU variants 106522 for the Smart Thermostat X, 106541 for the Smart Radiator Thermostat X, 106562 for the Wireless Temperature Sensor X and 106912 for a Smart Thermostat X UFH. The vendor model list includes the Smart Thermostat X UFH, but the fetched ledger has no compliance record for that part. Every certified X room device is listed with transport thread,bluetooth.
- Smart Thermostat X (RU04): certificate CSA23C79MAT41789-24, certified software 1.0, certified 2023-10-20; newer SKU 106522 certificate CSA2610ZMAT50739-24, software 1.4.289, certified 2026-02-24.
- Smart Radiator Thermostat X (VA04): certificate CSA23D71MAT41880-24, software 1.0, certified 2023-11-08; newer SKU 106541 certificate CSA26110MAT50740-24, software 1.4.289, certified 2026-02-24.
- Wireless Temperature Sensor X (SU04): certificate CSA23C98MAT41808-24, software 1.0, certified 2023-10-29; newer SKU 106562 certificate CSA26198MAT51036-24, software 1.4.289, certified 2026-03-02, and another SU04 record certificate CSA264EGMAT55112-24, software 1.4.289, certified 2026-08-16.
The 2023 records reference Matter 1.1; the 2026 records reference Matter 1.4.2. This is a certification ledger, so it tells you the device was tested against the standard, not every feature an app exposes. You can check any device against the same ledger using our guide to checking Matter certification, or browse the full SKU list.
Thread and Bluetooth only: the Bridge X is the Thread border router, not Wi-Fi
The CSA records for tado classify the Smart Thermostat X, Smart Radiator Thermostat X and Wireless Temperature Sensor X as transport thread,bluetooth. The room devices join your Matter fabric over Thread, and Bluetooth is only used during commissioning. None of the three room devices are Wi-Fi Matter end devices, so they need a Thread border router to reach other IP networks and Matter controllers.
The Bridge X NAT64 rule: third-party hubs may keep devices out of the tado app
tado's Bridge X article says a tado X setup requires a Bridge X, Heat Pump Optimizer X, or Wireless Receiver X. The Bridge X connects the Thread network to your home network and the internet. You can instead use a non-tado Thread border router: Google Nest Wifi Pro, Apple home hubs such as HomePod (2nd generation), HomePod mini and Apple TV 4K (2nd generation or 3rd generation 128 GB), SmartThings, eero, IKEA Dirigera Hub, GL-iNet S20, Home Assistant Connect ZBT-1 and Home Assistant Yellow.
Not all Apple TV models support Thread. tado's table in the Bridge X article lists the Apple TV 4K 3rd gen 128 GB (A2843) and 2nd gen (A2169) as Thread-compatible; the 3rd gen 64 GB (A2737) and Apple TV HD are not.
The catch is NAT64. A third-party hub must support NAT64 for devices to appear in both the tado app and the third-party app. A hub without NAT64 makes devices appear only in the third-party app; adding a tado Thread border router brings them back into the tado app. tado's Alexa article adds that Amazon's Thread border routers currently don't support NAT64, so devices added only to Alexa won't get tado firmware and security updates; set them up in the tado app first. For background on transports, see our Thread vs Wi-Fi guide, and for hub options see hubs and Thread border routers.
Where the Matter code lives on the Smart Radiator Thermostat X, Smart Thermostat X and Wireless Temperature Sensor X
Each tado X room device has a unique Matter code laser-etched on its body. On the Smart Radiator Thermostat X, you can see registration details by rotating the dial before the device has been commissioned to a Thread network, or remove the battery pack to find the code on the underside. On the Smart Thermostat X and Wireless Temperature Sensor X, the code is on the back of the device; pull the body away from the backplate to see it. The Bridge X, Heat Pump Optimizer X and Wireless Receiver X have no Matter codes and are not added to Matter apps, according to tado's Matter code article.
The printed QR code is only for the first installation. Once the tado app has added the device, the QR code is no longer valid for Matter activation. To link the same device to a second Matter app later, open the tado app, go to Settings > Rooms & Devices, select the device, then choose Matter Connections > Connect another app and use the numeric code shown there. If you have lost the printed code, see our lost setup code guide.
Apple Home needs the right Apple TV 4K model for Thread; iPhone 15 Pro can help only in iOS 18
Set up tado X devices in the tado app first. In the tado app, go to Settings > Rooms & Devices, select the device, then Matter Connections > Connect another app and follow the instructions to share it to Apple Home. Or in the Apple Home app, tap +, choose Add Accessory, scan the Matter QR code for a new device or enter the code shown in the app that already has it. You need an Apple home hub such as HomePod mini, HomePod (2nd generation), or an Apple TV 4K with Thread. tado's Apple Home article uses the same Thread-capable Apple TV model table as the Bridge X article. Apple's Matter page notes that with iOS 18 or later an iPhone can add and control Matter accessories without a home hub, and iPhone 15 Pro or iPhone 15 Pro Max and later can control Thread accessories without a hub, but a home hub is recommended. See tado's Apple Home article and our Apple Home Matter guide.
Google Home requires IPv6 and a copyable code because the printed QR stops working
tado's Google Home setup says you need a Google Home hub and a tado Bridge X, Wireless Receiver X or Heat Pump Optimizer X — or a Google Nest Wifi Pro. In the tado app: Settings > Rooms & Devices, select the device, Matter Connections > Connect another app, copy the Matter setup code. In the Google Home app: Devices > Add > Matter-enabled device, scan the QR code or choose Manual Entry to paste the code. Repeat for each device. Google's Matter page says IPv6 must be enabled on your home network; without it, setup can appear to succeed but control later fails. See tado's Google Home article and our Google Home Matter guide.
Alexa pairing: ignore the tado skill search, because Amazon Thread routers don't do NAT64
Alexa needs a Matter-compatible Alexa controller (certain Echo or eero models) and a Thread border router. tado recommends setting up in the tado app first. On iOS, copy the code from the tado app via Settings > Rooms & Devices > Matter Connections > Connect another app, then in the Alexa app select Devices > + > Add Device > Other > Matter > Try Numeric Code Instead > Enter Code. On Android, after Connect another app, select the Alexa icon and follow the instructions. The device discovery function that appears when you search for tado in the Alexa app won't work for tado X devices. Amazon's general Matter page says to install a Matter device within 30 ft of a compatible Alexa hub. Because Amazon Thread routers currently don't support NAT64, devices added only to Alexa won't get tado firmware and security updates. See tado's Alexa article and our Alexa Matter guide.
SmartThings and Home Assistant: use the platform's Matter flow; tado doesn't document SmartThings or Home Assistant-specific steps
tado's fetched articles don't give tado-specific steps for SmartThings beyond listing SmartThings hubs as possible Thread border routers. SmartThings' Matter page describes the general flow: open the SmartThings app, Add (+) > Add Device, scan the QR code or enter the setup code, then choose the hub and room. For Thread devices you need a Matter controller that includes a Thread border router. See our SmartThings Matter guide.
For Home Assistant, tado's Bridge X article lists Home Assistant Connect ZBT-1 and Home Assistant Yellow as possible Thread border routers. Home Assistant's Matter docs say to install the Matter integration, then use the Home Assistant Companion app on your phone: Settings > Connectivity > Matter, select Add device, and scan the QR code or enter the commission code. For Thread devices you need a Thread border router such as HomePod mini, Apple TV 4K, or Home Assistant with the OpenThread Border Router app. tado's support pages do not describe a tado-specific Home Assistant pairing menu. See our Home Assistant Matter guide.
MatterCheck matrices for tado X device types: Apple Home and Alexa thermostat triggers remain Unknown
MatterCheck tracks 3 tado products out of 393 products. The tables below are per Matter device type and platform, not a test of tado hardware. Hubitat thermostat and temperature / humidity sensor rows are from Hubitat's official List of Compatible Devices and release notes, checked 2026-10-28; no independent dated native hands-on test.

MatterCheck's results for the Matter temperature / humidity sensor device type (Matter temperature / humidity sensor page), per device type and platform, not a test of tado products.
Apple Home and Alexa list thermostats as a supported Matter device type, but neither fetched page states whether a thermostat reading can trigger an automation. Those two cells therefore stay Unknown in MatterCheck's matrix. A temperature sensor has no automation action because it has nothing to switch. These results describe device types in general, not tests of tado products, and tado's own app can offer features that Matter does not expose. For the full thermostat picture across platforms, see our Matter thermostat support guide.
Greyed-out 'Connect another app' after reinstalling the tado app, and the 'Matter could not be activated' checklist
Search phrases like "tado matter device linking is currently unavailable" map to two situations in tado's Matter troubleshooting article.
Connect another app button greyed out after an app reinstall, Android storage clear or phone change
If the Connect another app button is disabled in the tado app, you won't be able to connect the device to another Matter app. tado says this can happen if you reinstalled the tado app, cleared the app's storage on an Android smartphone, had an issue during installation, or are using a different smartphone from the one used for the original installation. The device may still appear connected in the tado app and remain controllable there. To restore the button, factory reset the affected device, add it again in the tado app via Settings > Rooms & Devices > Add Device, then try connecting to the other Matter app again.
Matter could not be activated
If you see a "Matter could not be activated" error, tado suggests checking that your smartphone and tado X devices are on the same Wi-Fi network, checking that your home network supports Matter communication, disconnecting any VPN, moving the Bridge X closer to the router and other tado devices, and restarting your smartphone and Wi-Fi router. If pairing still fails, see our device not pairing guide and our remove and factory reset guide.
Multi-admin with tado X: the last command wins, extra Matter networks cost battery, and hot water is not exposed
Matter's multi-admin feature lets you share tado X devices across multiple ecosystems and voice assistants. The last command given takes precedence across all systems, according to tado's Matter apps article. Adding a tado X device to multiple third-party Matter networks may slightly decrease battery life; managing devices in the tado app plus one other smart home platform shouldn't noticeably affect battery life. Matter integration doesn't currently support domestic hot water control. For more on sharing devices, see our multi-admin guide.
Do you add the Bridge X to Matter apps?
No. tado says you add the room devices one by one, but you don't add tado Thread border routers to Matter apps. The Bridge X, Heat Pump Optimizer X and Wireless Receiver X have no Matter codes, according to tado's Matter code article.
Which Thread border router should you run for Home Assistant?
You don't need a tado Bridge X if you already have a compatible Thread border router. Home Assistant's Matter docs list HomePod mini, Apple TV 4K, or Home Assistant with the OpenThread Border Router app. tado's Bridge X article also lists Home Assistant Connect ZBT-1 and Home Assistant Yellow as supported third-party hubs. tado doesn't publish a tado-specific Home Assistant pairing path, so use the Home Assistant Companion app flow described above.
Do tado X devices use Wi-Fi at all?
No. The CSA ledger entry for tado lists the Smart Thermostat X, Smart Radiator Thermostat X and Wireless Temperature Sensor X as transport thread,bluetooth. The room devices join Matter over Thread; Bluetooth is only used during commissioning. For the practical differences, see our Thread vs Wi-Fi guide.
What about V3+ devices?
tado's Matter articles only cover the X room devices. The V3+ to X article covers uninstalling V3+ devices to install X devices, not adding Matter to V3+ hardware. There is no V3+ Matter certificate in the fetched CSA model list for vendor 4942, and the fetched tado code article points to the X devices only. See tado's Matter code article.
