So, you managed to get it working in the Tado App and Home Assistant? I have a Google Nest Hub 2 and was able to do the initial pairing / adding of the thermostat in the Tado App and the device does show up, but immediately after adding it, it goes offline.
There was no problem adding it to Home Assistant via Matter though and in HA the device functions as expected (can see and adjust the temperature), but the device still shows offline in the Tado App.
Any ideas?
Also when restarting the TRV’s?
Costco order still hasn’t turned up. I gave up waiting and cancelled it.
Ordered from Amazon DE/FR instead. TRVs have arrived, just waiting for X receiver due tomorrow. Cheaper too.
I have the exact issue. I bought the starter kit with the valve and the boarder router, adding the valve to the app worked fine. First I didn’t get the link device option, so I did a factory reset on the valve and then added it back in the app. It showed the link device option. I tried it in 2 ways: with the setup code (didn’t want to add) and via the option in the app to connect it to HA. Nothing worked no matter what I did. I gave up and returned the kit. Maybe in the near future it will work better. We’ll see.
For anybody experiencing similar connection issues; despite what tado says move you’re bridge away from the wifi router… i moved mine a bit further away and havent gotten any issues since!
Anyone can help me out with this mystery?
I successfully linked 2 out of 3 Smart Radiator X’s to Home Assistant as Matter devices, using the ‘device linking’ option in the Tado app for these 2, but the 3rd one simply doesn’t show the ‘device linking’ option in the Tado app!? They’re running the same firmware, but one simply doesn’t show this feature in the app!?
Edit: solved it by removing the radiator thermostat from the Tado app, factory resetting it and re-adding it. After that, the ‘device linking’ option appeared in the Tado app, just like the others.
Can I use it by somehow connecting Home Assistant to the bridge? Reading the discussion it seems you all have USB-connected radio with the border router. But the bridge that comes with the Tado X kit should provide that, so I should be able to use that. It has only port 8050 open. Does it work somehow?
I installed the Tado TBR and 1 valve as a test. First time it didn’t work at all, no pairing option, so I reset the device to default and tried again. Option was there but couldn’t pair it to HA. Checked the logs… Ipv6 not enabled… Stupid me. After that it was easy to pair.
So far it works fine with my already setup system with zwave devices (will be replaced), but I had to move the Tado bridge to another, more centralized place in the house. Haven’t tried if it still works without Internet connection.
What I’m missing:
This, I was appalled at how broken the ChatBot links were for decent information, so you end punching through it all to the human interface kb (which is scarce). I reasoned that you should have all your ducks in a row before launch; that way, if there are issues you can quickly get on top of it not play catch up. I was fairly negative on the Tado Community whilst trying to remain polite. I received answers by their matter compliance SME; threw it into a draft letter with their replies to each statement (refreshingly honest and frank), first apologising to their staff for doubting the Tado X Wireless Receiver (EU) was a matter compliant Thread Border Router, the way it was explained … I have considered it, my thoughts, as an Edge Thread Border Router, as I am not sure what it brings to the party as a TBR. Then I continued by ripping into their ChatBot links. Sent it back for company review that offers them an opportunity to reply, then publish (they have already given me that permission but I don’t want to do them a disservice since Tado V3+ was flawed for a lare house but did its job after a fashion (but ate batteries, the Internet Bridge was a touch lightweight requiring careful positioning); the Tado X has got real potential once they have caught up with everything else the Tado V3+ offered … like pre-heat tied to outside weather conditions.
Bought my stuff from Tado direct (I received the 50% discount offer, which for 20+ units is a good saving). Reference Room Sensors apart from TRVs (I dislike the naming convention on the range), there are 2 … Tado X Wireless Sensor (3 x AAA) & Tado X Smart Thermostat (still 3 x AAA BUT can be wired to boiler in place of room stat). I used the Tado X Wireless Receiver (EU) ‘cos it uses a plug (great if you are away for long periods … I don’t to add anything else to my holiday prep list. However, if need be, we have an 18m buried wire to boiler site. By the by I can see everything on Eve App/Settings/Thread except the Tado X WR (EU), hence get it all onto my HA Green 
Aye, I put together my take on prepping etc for Tado X.
Sorry if I butt in, but for many it is mid-winter so their boiler CH is very important. That is why we all try to help each other.
Here’s my take on what needs to happen:
Installing Tado X system, a users guide (Amendment 2 dated 19/12/2024)
My setup was based on Ubiquiti Unifi UCG-Max router with U7 Pro Wall APs & oil-fired boiler (located 18m from stone house) using StarLink as internet provider.
Preparation
before installing Ensure IPv6 is enabled on your router (most routers have this enabled, but people like to fiddle with settings). Thread Border Routers & Thread require this standard (Reference Google Nest FAQs).
Strongly recommend that you consider a separate IoT network, perhaps thru vLAN or using the Guest side of your Router, that you have selected solely for 2,4Ghz IoT network use.
My preference, delete all of your other networks from your phone for the install of the Tado X system, then you won’t have your errant phone chasing 5Ghz whilst installing your first Tado X component, the Tado Bridge X (I kid you not, it works. Simple enough to restore other networks post-installation). I don’t like the Tado X naming conventions at all.
Look at your current distribution of Thread Border Routers (Apple Spkrs, Apple TV, any EveHome products will be either Thread Border Routers or Thread Endpoints, See Notes below)
When ready, if you have Tado V3+ previously installed then delete that home (there is no Tado X compatibility with V3+ or older, except the air conditioning wireless control), you cannot progress without deleting it using the Tado QR cards. Personally I stripped all reference of Tado from my phone and started with a fresh Tado App using my sign in details.
Installation of Tado X units
Install Tado Bridge(s) X on a clean Tado App using QR code on card attached to lid of box.
Then install Tado X Smart Thermostat (Thread Border Router compliant) or Tado X Wireless Receiver, again using QR on card inserted in lid of box (see Notes below). I found the Tado Pro App particularly helpful to confirm my existing wiring was correct (great app 
)
Install Tado X Radiator Thermostats. Again, back to the QR card on the inside of the box lid. Allocate to a room.
Same with Tado X Wireless Temperature Sensors, QR code then allocate them to a room.
When you have finished building your home, remember to configure each room to your Tado X Wireless Receiver (EU) (TR plus 10 digits) or Tado X Wired Smart Thermostat ( GR plus 10 digits). Look at your settings (Settings/Rooms & Devices) you will note Tado Bridge X & Tado X Wireless Receivers (EU) are not allocated to a room (they sit at the bottom of the Rooms & Devices page under Other Devices).
Set your schedules (remember you can copy them to subsequent days or to another component within the App).
You can check your Thread Border Router & Thread Endpoint distribution using an outside App such as EveHome/Settings/Thread (Tado X do not currently have this facility available)
Commissioning your heating system
Position yourself by your Tado X Wireless Receiver (EU) (or Tado X Smart Thermostat, wired) then open Tado App and the Home page should be displayed with all your rooms, hallways etc. Your schedule may already have started, otherwise select a couple rooms to heat (or, if you like wasting fuel select Boost Heating this opens all room radiator valves). If you have previously pressed “Turn off all rooms” then press Resume Schedule at the top of the page. There may be a delay of several seconds before you hear or see any change at your Tado X Wireless Receiver or Tado X Smart Thermostat (wired), this is perfectly normal.
Look at your Tado X Wireless Receiver (EU), hopefully you will have 3 steady WiFi lights and the Heating Light illuminates with a click from the relay to your boiler. If you have wired your Tado X Smart Thermostat, then you will hear a click from it.
The boiler works after a short delay (hurrah).
Now press Turn Off on the Tado App Home page, the Tado X Wireless Receiver heating light will go out and you may hear a click.
The boiler stops, although your heating pump may continue dependent on your wiring to boiler (OpenTherm, other standards or just a basic On/Off switch).
Back to Resume Schedule on the Tado App Home page, your boiler will then control itself after a short delay, just make sure it controls itself within the temperature output you have set on the boiler faceplate.
If you look at your Tado X Home page, you notice that the temperature cycles slightly either side of your desired room temperature. Perfectly normal.
Go to the Settings page of the App, sort out your personal preferences for geofencing etc.
Pat yourself on your back, celebrate by taking your dog for a short walk, tell your No2 son (Final year studying Computer Management in France, all 6’3” of him, who looks suitably unimpressed but wasn’t here, and he diss’s his replacement phone, my old iPhone X, after he broke his Samsung) and smile with fingers firmly crossed …
If you write about Tado X too often, you may live to sigh at their naming convention.
