Here’s the error I’m getting in the logs:
Can’t lock car (MY VIN). VIN unknown or feature not availabe for this car.
6:45:42 PM – (WARNING) MercedesME 2020 (custom integration)
Please go to the integration option dialog and activate „ Disable capabilities check“.
That did it, thank you so much. Been a while since my original setup so I forgot a bunch of the steps.
Hi.
I note you say that your code uses the Mercedes API. In my Mercedes me app, I can change the interior led colour. It’s called the ambient lighting. Can I also do this through your add-on please.
Dear MB-Integration Users,
slightly Off-Topic (ok, Smart cars are part of the MB Family), but I have published a first version of a “Smart EQ Connect”-integration. The sensor set is limited like the trunk of these cars 
have fun

Hey dear MB hass.io community,
I’m having some issues, and can’t really come along with a proper solution.
I can’t see any entities in home-assistant. What I did was installing via HACS and configuring my account. It seems to work but I don’t get any more data…
What I can see is within “integrations” it shows mbapi2020 and Mercedes ME 2020.
Car is a GLE 2021 / W167.
I’ve attached a screenshot.
Thanks in advance!
Somehow I saw that the remote diagnosis option was deactivated within the app… It’s still activating but maybe that was the reason why?
Hi @P1Rebo ,
do you see the car data in the mobile app already? If yes, just restart HA. If nothing is visible, please enable the debug log and share it here or via a private message.
BR
Rene
Thanks @ReneNulschDE for the fast reply. It still remains in activation within the Mercedes me iOS app. As I saw this is normal and can take some time. In HA I still can’t see any entities yet. I will give an update asap.

After installation this component works well for 3 hours in my HA configuration.
After that period of time for every 5min I get errors and component stops to work because of token error.
Do You know what can I do to solve it?
This component worked in my config for months and yesterday after deinstallation and new installation something has changed. Yesterday after 3 hours from installation it stopped to work. Today I tried and situation is the same. After few hours it stopped to work again.

per me è la stessa cosa da ieri, dopo l’aggiornamento, ha smesso di funzionare
for me it’s the same thing since yesterday, after the update, it stopped working,
is there any solution?

Hi,
I see this error too since Friday. Let me check if there was a change in the MB-Auth-Backend or if I made a mistake.
BR
René
I have published a release “Release 0.5.14 - Bugfix refresh_token error”. This should fix the error:
File “/usr/src/homeassistant/homeassistant/config_entries.py”, line 304, in async_setup
result = await component.async_setup_entry(hass, self) # type: ignore
File “/config/custom_components/mbapi2020/init.py”, line 105, in async_setup_entry
token_info = await mercedes.client.oauth.async_get_cached_token()

token_info = await self.async_refresh_access_token(token_info[“refresh_token”])
KeyError: ‘refresh_token’
A ReAuthentication is required - See the red box on the integration page after restart.
Background:
MB changed something in the OAuth Backend. In the past the refresh_token was always present. Now the refresh_token is missing sometimes… 
@bobofruit , @dolam : May I ask you to recheck?

Good morning Renè,
now it has authenticated and MercedesMe has communicated the code but neither the device nor the entities appear anymore
Did you reauthenticate via the integration page? There is no way without the reauthentication because the component lost the refresh_token.
Other option:
- delete the component via the integration page
- delete the file .Mercedes… in the HA config folder
- restart HA
- add the component again
Hi, @ReneNulschDE
I have uninstalled everything and installed again new version.
I can not see any problems in logs but we have to wait few hours.
Component works in Poland.
Thank You and regards

Hi @ReneNulschDE,
First of all, I’d like to thank you for your amazing work! I’m totally new on HA and your custom component was one of the reason why I’m now using HA.
FYI I’m in France, so you can add ‘FR’ on the list of the countries where your component works
Thanks again and best regards

@ReneNulschDE Great work! one of the easiest integrations I’ve dealt with so far.
My contribution to this thread, I’ve integrated a telegram bot into my system. Reason being - sometimes you’re on a train and want to do things, but not wait for an app to load to with cellular/mobile signal. So, why not ping a command across and it’ll get done when you are out of said tunnel. 
I’ve got it to:
- list car stats (I’ve created some custom sensors to tell me window states & sunroof states- ie, open, closed, partially opened, venting, moving).
- Flash your lights (cause this was amusing - and not something the default app does)
- lock doors
- unlock doors (not sure this is a good idea)
- close windows
- close sunroof
- turn on climate control (pre-heating for winter… assume aircon for summer!?)
Code to get you going if you wanna - and don’t forget to replace sensors with your own. (ps, just worked out the plugged in status indicator - so this is wrong currently in the code below).
