Thanks! I was just about to highlight the same problem. My post about the workaround is updated.

I thought I had solved it using A320Peter’s method, but after reading your post I tried to alter the temperature from HA and it failed.
Using the wmalgadey files (changing my.tado.com to auth.tado.com on lines 115 and 140 in interface.py as previously mentioned) everything is now working. 
Thanks, post has already been updated.

I confirm the workaround for Hassio does the job. Moreover, the interface.py file on wmalgadey has been already patched, making even easier to fix the problem. Thanks to everybody.

followed this and worked for me this morning,
Thanks guys as this issue was starting to cause me a headache
you can create your own custom component and just point python-tado to the latest release that was put on pypi 11 hours ago.
It worked to get temperature data and change the heating operation. However, when you select “Off”, you get the following errors:

Same here, I can switch the thermostat on with “manual”, but not off!
I follow the discussion.
Did you try my solution, doesn’t involve editing the container and uses the local dependencies so won’t get overwritten.
More detail here
How did you get it to work on the RPI? I can’t edid any files or something.
Did you just copy a file en put it in the directory?
Well mine is Hassio on intel-nuc but the principle is the same. You load a custom component by placing the files in <config directory>/custom_components/<component name>.
In this directory create a folder tado and copy the official github files from core/homeassistant/components/tado at master · home-assistant/core · GitHub
Now in the __init__.py file change the line that says REQUIREMENTS = ['python-tado==0.2.3'] to be REQUIREMENTS = ['python-tado==0.2.8']. This will force the component to download the required files on restart as the files differ from the built in ones.
Thes files will be in <config directory>/deps/lib/python3.7/site-packages/PyTado/<component files>.
Once these exist after restart you now change original file back to REQUIREMENTS = ['python-tado==0.2.3'] . This downloads the compatable python files to that deps folder. Upon another restart you now have the files in deps where you edit the lines mentioned above. When it is fixed in an official release just remove the tado folder from custom_component to use the normal tado component.
For some reason my Hassio isn’t using the custom tado component but the built in one and therefore isn’t downloading any dependencies…
I copied the __init__.py, climate.py, device_tracker.py and sensor.py from github to /config/custom_components/tado also set persmission to 777 to make sure.
Do I need to call the custom component in the configuration.yaml? I’m just using the normal
tado: username: password:
Did you change the dependency so it forces the download of the deps folder. I assume your custom_components folder as you wrote it is a spelling mistake?
Thanks for your help. It is working perfectly!

Found it! I spelled it _init_.py instead of __init__.py
I shouldn’t attempt these things in the middle of the night…haha
Thanks!

Same problem here, I can access the sensors but cannot seem to control the thermostats, getting an error 422 whenever I try.
Have completed the custom_component method and then edited lines 115 and 140.
Edit: sorry I should say that I can control the thermostats in manual mode, I just can’t seem to over ride the smart schedule.
