Tado Integration Stopped Working

kwatt · March 21, 2025, 11:17am

My Tado system stopped being recognised by HAss this morning and I canot work out why.

I got a 403 error but could loging to Tado no problem so I tried to delete and reinstall the Tado integration but I can’t, I get an “unexpected error” even though I know, 100% for sure, that the login credentials are correct.

Then, when I try to login to the API, my.tado.com per the instrucitons I get:

Well that wasn't supposed to happen.
400 invalid_grant : A redirect_uri can only be used by implicit or authorization_code grant types.

Does anyone know if this is a Tado issue or one with the integration and to me, it looks like a Tado thing is broken?

Yup, just reloaded the integration and mine is dead too…

OK, bit more info here:

[Notice] Deprecation/removal of password flow support from auth.tado.com

### The problem Hi, Mike from tado GmbH. We wanted to let you know that we will… be removing support for the password flow on our Oauth server. We will be removing the functionality by **~~15 March 2025~~** **21 March 2025**. The replacement for this is to use the device code flow (for more info see [here](https://oauth.net/2/grant-types/device-code/) or [here](https://datatracker.ietf.org/doc/html/rfc8628)). This flow is more secure and more appropriate for dealing with use cases where there is limited access to a browser and/or there is no possibility to support the redirect in an authorization code flow (e.g. on the command line, in a script). This can be used in tandem with the refresh token flow and **must** be in the case that you want to have long-lived access. Our current analysis finds that users using the password grant flow, including those through Home Assistant, do not, in general, use the refresh flow. This causes significant load on our servers because each password check requires expensive hash calculation. For more information, see also this [post](https://support.tado.com/en/articles/8565472-how-do-i-authenticate-to-access-the-rest-api) on the tado support page. Note, I've posted this also on the tado client currently being used by HA (see [here](https://github.com/wmalgadey/PyTado/issues/155) also with a code snippet). ### What version of Home Assistant Core has the issue? core-* ### What was the last working version of Home Assistant Core? _No response_ ### What type of installation are you running? Home Assistant OS ### Integration causing the issue tado ### Link to integration documentation on our website https://www.home-assistant.io/integrations/tado/ ### Diagnostics information _No response_ ### Example YAML snippet ```yaml ``` ### Anything in the logs that might be useful for us? ```txt ``` ### Additional information _No response_

In short, they’ve deprecated the old auth mechanism as of TODAY and the developer is very kindly rushing through a rewrite to migrate to the new auth flow. Obviously events have overtaken a bit, but I suspect a bit of patience to wait for an update and things will be good again.

I am the maintainer/developer of the Tado integration: apologize to anyone being affected currently. We’re doing our best to get this in as soon as we can to get the new authentication flow in. The library and integration have been upgraded accordingly and now it needs to go through HA’s release cycle. The Core team is aware of this and helps around.

Current best approach
The refresh tokens still work, effectively meaning that all installations should be able to refresh their authentication credentials with Tado. Please do not reload the integration or restart HA. This will automatically reset the credentials. The password flow is disabled by Tado.

I didn’t foresee so many people would require a restart on day one. The refresh token approach would bridge the release cycle gap, in the best estimations.

Hmm, i read this too late, i did a reload of the integration. What to do now? Wait for the fix or do something else?

ajmorr_is · March 21, 2025, 3:50pm

Me too, just restarted HA for a different thing and saw that my Tado integration was not loading. Hopefully a quick fix to push a revised login method will appear.

Restarted homeassistant. Now tado integration down. Innstalled homebridge plugin Tado platform next and got everything back in ho.eassistant.

maurizio53 · March 21, 2025, 5:22pm

What you mean with homebridge plugin? Where you got it and how you installed?

Ton2 · March 21, 2025, 5:48pm

I have a proxmox system with some vm and some lxc containers like homeassistant and homebridge. In homebridge i installed the tado plugin i mentioned above. Then i can integrated this in homeassistant.
Works okay.

maurizio53 · March 21, 2025, 5:50pm

Ok, but that’s not for my system… forced to wait a fix!

kwatt · March 21, 2025, 6:29pm

I can add Tado to Apple Home no problem but not to HAss directly before adding it to Home. All seems fine in Apple Home though, no issues there it’s just HAss that can’t see Tado due to the changes Tado has made.

So I’m in the same boat, have to wait for a fix.

Ton2 · March 21, 2025, 7:54pm

Can t you connect it with homekit integration in homeassistant

krskrab · March 21, 2025, 8:21pm

HomeKit Device:

Rofo · March 21, 2025, 9:13pm

Annoyingly I had a HACs update that required an HA restart, so thats also put tado out of action for me until the next update.

Also, the homekit integration does not expose the hot water entity, which is used by some of my automations, so its not an option for me to switch to it.

Ton2 · March 21, 2025, 9:59pm

Wich homebridge plugin did you use or how did you install this? I cannot see .y tado bridge.

kwatt · March 21, 2025, 10:06pm

No, for Homekit no Tado bridge or devices show up but, I don’t know that I want to do that and potentially blow up a whole bunch of automations.

DariukaB · March 21, 2025, 10:33pm

Homebridge Tado Platform Next

looks like they’ve managed to update the plugin for homebridge to use new oauth method

Ton2 · March 21, 2025, 11:35pm

Yes this works

liviumac · March 22, 2025, 7:35am

Hi, can you explain how to get this working again in homeassistant?

I have the Tado integrated locally via homekit, but I also need the internet integration because homekit does not work from time to time and also it does not show all thd entities that I need.

Thank you!

Alo I have no connection with Tado anymore.
Yesterday there was a long power outage which caused Home Assistant to restart automatically when the power was available again…
