Tado integration fails Outh (Tado V2, succesful tado website login) - timeout issue?

[Geekerbyname]

The problem

Tado integration suddenly gives me an Authentication Expire error and prompts me to re-auth. It takes me to the Tado website with the correct auth code, and I am successful in that part. The integration immediately gives me an 'Authentication timed out' error then an 'unknown error'

Subsequent attempts to auth give the same timeout error and I need to reload the Integration before attempting again

I have deleted all Tado cookies and cache in the browser, signed out and logged again

What version of Home Assistant Core has the issue?

core-2025.5.3

What was the last working version of Home Assistant Core?

core-2025.5.3

What type of installation are you running?

Home Assistant Container

Same here since yesterday and i find out that IOBroker has the same problem !!

i tested a little bit more.

The same problem also occurs if you log out once with the manufacturer tado app and try to log in again. It seems that tado has a server problem. or if you try the function ‘let display flash’, an authorisation error also occurs.

[Geekerbyname]

Interesting - it did feel like a server issue initially. But I found no status showing issues anywhere. On the other hand, I've seen some big issues around the net over the last few days - particularly Microsoft's servers/services being very slow. Hopefully just a waiting game ...

[aberkeley]

i ma seeing the same issue - tried reboot of HA. Login/.out of tado site. when i return from the website i get:

even when the authentication on the web is successful

Also seeing this behaviour.

[1967maverick]

I concur - same issue with my Home Assistant / Tado integration. Ive also tried some of the same solutions as previous commenters above to no avail. HA 2025.5.3 with latest Tado integration.

[cracyfloyd]

i was able to fix the error. luckily i had a second assigned account. with this account i deleted my account and created it again and lo and behold everything works again.

The integration checks every 5 seconds for a result at Tado's servers. It will timeout, if within five minutes no results for the login are available. Normally should should be rather instant in terms of user experience. I'll check with Tado if there were any hick-ups on their end or that I should continue the troubleshooting within Home Assistent.

[1967maverick]

I have raised a case with Tado, which has now been escalated. Browser connection is fine (app.tado.com) But the Tado App on both iOS and Android gets an error (attached).

I think the issue we are seeing in HA and the issue I am seeing in the mobile Apps is linked. My guess right now ( no facts to back up this hunch) is that since Tado changed its authentication a couple of months ago, if using the HA Tado integration, you have to re authenticated after every HA restart. Perhaps Tado have been counting the re-authentications, and now our HA installs / Tado accounts have hit a max value and Tado has locked us out when using the authentication method that HA AND the mobile Apps use. @cracyfloyd - if my guess has merit, perhaps your action of delete / recreate your account reset this mystery counter back to zero.

Anyway - Tado engineer is looking into my case. He asked me to confirm my account email - perhaps he will do a reset of the counter for me:-)

[Geekerbyname]

I'm unable to invite another user from either the Tado Web site or the Mobile App. Or delete a user. I'm not sure if this is just awful design or a backend issue. My Guess is it's also some back end Tado Auth issue

[1967maverick]

Same here @Geekerbyname . Cannot add / delete any linked users. I too guess same related issue.

[1967maverick]

UPDATE: reply from Tado engineer:

“ The developers are aware of the issue, and they are working on the solution. Sorry for any inconvenience. We will inform you as soon as we have an update.“

So looks like they are working on a fix!!

[Geekerbyname]

Good news - thanks @1967maverick

[1967maverick]

Further feedback from the Tado engineer: "Yes, they are on it; it seems a global issue. I'll let you know once I know more"

[kapet]

The problem should be fixed, if not please reply here. This was a synchronization issue between the multiple layers and caches that handle authentication. It affected only a very small number of tado users (far below 1%) and only affected homes created a long time ago, so unfortunately this took most of the day to track down.

Thanks to Erwin for escalating this to me this morning!

(edit: removed the statement that this was limited "V3+", this was based on an assumption that did not hold true.)

[1967maverick]

I confirm both App and Home Assistant issues resolved. Yes I replaced my system with V3+ last year but I had my original system / account for 10 years, so the obscured logic applies to me! 😃

[holymountain92]

Works again! thanks :D

[Tuffert]

Unfortunately, still not fixed for me :(

[Geekerbyname]

Working for me now too. I've had the system almost since launch I think.

[kapet]

@Tuffert - dropped you an email, to the address in your tado account.

[JoniSykes]

Still not working for me :(

Do I need to do anything in HA or Tado app to fix this?

[JXGA]

Still not working for me :(

Do I need to do anything in HA or Tado app to fix this?

Have you tried a reboot of HA? Solved it for me.

[Uritec]

Same Problem, still not working for me.

[ITGuruWoo]

I had to reboot my HA yesterday and since then Tado won't connect, keeps timing out. Tried reentering password but just times out. I am on an old version of HA 2024.7.2. Pleqase help

Thanks

Update to the latest Home Assistant version. In the main time Tado has switched it's authentication methods and the latest versions of Home Assistant contain the new methods. :)

[bangboomben]

My issue is similar but different. I get the authentification bug from time to time. Meaning I'm being asked to re-authenticate, which works as expected. But then, after some days, or HA restarts, I'm being asked again, to re-authenticate. Doing so, works again. And that's the process at least 2-3 per month.

[jakubklimek]

I am also having issue with authentiction to Tado. I am running HA 2025.6.3. When I authenticate with Tado, I get a green tick in tado, success message in HA, but in a few seconds, the integration says it needs to authenticate. The logs contain various errors:

[erwindouna]

@jakubklimek the shortSerialNo indicates you're using Tado X. Is my assumption right? If so, then please be noted that the Tado integration does not (yet) support Tado X.

[jakubklimek]

@erwindouna Yes, Tado X. Ahh, ok, I was under the impression that the support for Tado X was already added. My mistake then.

[willsmarthome]

This problem has been going on for a long time. Is there anything more known about a solution and when? I have tried the Homekit integration, but then you miss a number of control options. I do not use the X version of Tado. Thanks in advance
