MMM-Tado - Tado API Login no longer working (403 error) — any fix?

[chichi1887]

Hi everyone,

I hope it’s okay to write in English – it’s not my native language, so please excuse any mistakes 😊

I’m currently having issues with the MMM-Tado module. It used to work fine, but now I’m constantly getting the following error:

Error: Request failed with status code 403
“error”: “forbidden”,
“error_description”: “Please migrate: https://support.tado.com/en/articles/8565472-how-do-i-authenticate-to-access-the-rest-api”

After testing my credentials directly via PowerShell and curl, I found out that Tado has disabled the old OAuth/password login flow, which the current MMM-Tado modules seem to rely on.

I tried multiple forks, updated everything, checked my credentials, even tested the API manually – but the result is always the same: 403 Forbidden.

MagicMirror logs show this over and over:

MMM-Tado: Not all data present

So I believe the module is no longer compatible with the latest Tado authentication system.

❓Has anyone already fixed this issue or found a workaround?
Maybe someone already updated the module or uses another approach (like a proxy, Home Assistant, or a newer fork)?

Thanks a lot in advance 🙏
And again – sorry for my English! 😅

@chichi1887 I have seen that the node-tado-client npmjs package has been updated to v1.0.0 to cater for the new OAuth2 flow. I would suggest opening an issue on the module Github page for the module developer to fix.

There is a fix from an user. Maybe give it a try 😁

@mishu28nmv
What exactly do I need to do to get MMM-Tado working again? I searched the logs for the URL that should be generated, but couldn’t find anything.

@JoeFranz did you look at the fork

https://github.com/daydy16/MMM-Tado

[JoeFranz]

@sdetweil I read it, but I can’t find the URL in the logs… :-(

[sdetweil]

@JoeFranz oh, i see

are you sure this new module is installed instead of the one you were trying?

[JoeFranz]

@sdetweil I’ve now reinstalled it from this site. I can’t find the URL in the logs.

[sdetweil]

@JoeFranz how are you displaying the logs?

[JoeFranz]

@sdetweil pm2 logs MagicMirror

[sdetweil]

@JoeFranz probably need more lines

pm2 logs MagicMirror --lines=100

pm2 logs MagicMirror --lines=100

OK, the URL is now displayed :-)
I’ll try it out, thanks!

@det I have the same problem.

[mishu28nmv]

This is my solution. Just install the https://github.com/daydy16/MMM-Tado
In the config file:

{
		module: 'MMM-Tado',
		position: 'bottom_left', // This can be any of the regions.
		config: {
		updateInterval: 900000 // miliseconds-15minutes-96times per day < 100 
			}
		},

After you launch your Mirror with “node --run start”, you receive in the terminal this:

MMM-Tado: Device authentication required. Please visit the following URL: 
https://login.tado.com/oauth2/device?user_code=XXXXXX

You put that URL in your browser and submit the code. That’s it.
Hope it helps!
