Small Question, is it possible to set the device into a force open or force closed state? or only temperature setting? reason i ask is that we use a woodstove that is connected to the heating system, and there must not be a closed system…
and final, is the 25degrees limitation gone in the new system??
How to you share the radiator thermostat X from the app? The support page says to go into the app, Settings, Rooms & Devices, select the device, scroll to the bottom and select “Device linking” - but I find no such option on the device page?!?
You have the NO (normally open) and NC (normally closed) terminals of the thermostat, and you can turn off the thermostat. So depending on your needs, just hook up the right terminal and then turn off the thermostat.
I can set it to 30°C here, so I guess? 
Under Settings → Rooms & Devices → and then select the Thermostat X, at the very bottom I have the link here. If you don’t see that, you sure yours is a Thermostat X?
Are you using the tado iPad or iPhone app? The “Device linking” option seems to be missing on iPad. iPhone is fine for me.
@agners questions:
To answer my own questions.
Yes it has all the functionalities if you add it in the tado app. Via matter is only the temperature and humidity.
Yes you can buy it without bridge
Sounds good. How did you add it to HA though?
Hello, great review. Where in the tado App can you Share the device / Handover to the HA Matter Controller…i cant find this option… Android…?
@luchtgitaar1 @kaihawaii In the tado app go to “settings” → “rooms and devices”. Then tap on the tado x thermostat. On the next screen, at the bottom, tap on “pair device”.
Got it. Thanks a lot
The integration of Tado X devices via Matter over Thread does not seem to work when using an Echo 4 as a Thread Border Router.
When I try to connect the devices to the Tado app first, it tells me that I need a Thread Border Router even though I have an Echo 4. Do I still have to explicitly mark the Echo 4 as a Thread Border Router in the Tado app? If so, how?
When I try to connect the devices to Home Assistant first, Home Assistant tells me that the device needs a Thread Border Router even though I have an Echo 4. My Echo 4 Thread network is also only displayed in Home Assistant as “Other network”, but not as “Preferred network”.
So I first connected the Tado X devices to the Echo 4 Thread network in the Alexa app, then shared the connection with Home Assistant. This worked, but as described by the thread author, I can no longer connect the devices to the Tado app.
Update:
The Tado support page states that currently only Apple devices work as non-Tado Thread Border routers.
However, @agners said that he had integrated the Tado X devices using a SkyConnect stick.
It is also working with nest hub devices as non-Tado Thread Border routers. That’s what I did. I have an android ecosystem.
I have now bought a SkyConnect Stick and after several restarts of the smartphone and factory resets of the Tado X devices, all devices could finally be set up.
By the way, I had to do this too: Pure HA+Thread, "Border Router required" - #16 by WallyR
So maybe it would have worked with the Echo 4 after all. But for me it’s okay that I’ve now bought a SkyConnect stick because I want to gradually get rid of the Echos and Alexa anyway.
As @agners has already mentioned, all the additional functions are missing. For me personally, the window open detection would be enough as a sensor. Everything else can also be built with automations or with Better Thermostat directly in Home Assistant.
Hi a question here. I was interested in changing the heating based on energy tariff. Tado heatpump optimizer X supports this with a subscription (a bit too much and don’t want to depend on the cloud). There is no machine learning yet in Home-assistant to do this task 
but maybe an automation could try to do this, but I guess it would be hard to optimize with an automation. If the temperature drops too much it cost more energy to warm up and other factors and comfort are hard to build into an automation.
My question is the control and sensor information good enough to setup/train a local ML network?
What are al the reading you can get from the Heating Pump?
I was before looking at Ngenic Tune - smart thermostat helps you save energy and money – Ngenic
But this has also depended on the cloud. You can do a onetime payment. But still if the service stops working than you have nothing.
Tado looks a better option now as it has some local support.
Installed the tado X today,
Tado app
Got it working with the openthread border router (sky connect) after some issues and restarts
But can’t share it with matter,
Anyone seen any solution for this?
I have installed it from the native integration. In Home Assistant it does not let me control the temperature,
If it doesn’t even serve me for that.
I’ll return it to Amazon
Is it possible to read the battery level when integrated with Home Assistant over Thread+Matter? That would be the only thing I’m missing, compared to the cloud.
Hi, thanks for the great review.
I always like to be resilient in case if Home Assistant crashes.
If I use de Tado Bridge X with several smart valves, with full control in the tado app, can I then just share those to HA and control them fully (read/edit desired temperature, view all sensors) as well?
I just want to avoid relying 100% on HA and thus, don’t want to only rely on my thread stick connected to my server.
Thank you
It’s quite a reading all this. I have no luck connecting Tado X Bridge or the Thermostat to anthing. Its own app, or HA, just nothing. Nothing works. I got a feedback from Tado technical that in order to add Tado X devices on needs a device that runs on Android 14, they say anything older doesn’t work. It seems to me A) very strange that you have to use a super new phone or tablet and B) there must be another method to add those through Matter but, that doesn’t seem to work for me either.
I follow the guides and instructions but all I get is “Something went wrong”.
I would love someone to illuminate me on the Android 14 thing as well as someone might have an idea what I’m doing wrong.
