Mercedes Me (Connected Vehicle)

[K0enH]

hi All,

I am a proud owner of a new 2021 C-class
I have setup a developer account and followed all the steps.
however I keep getting errors in my logs of domoticz (have it set to run every minute).
as you can see below the errors are different every minute and I have no clue what is going wrong as the behavior is different every minute.
anybody with a clue?

A 403 code means Access Denied…

Check the log if the module has successfully retrieved an Access Token (which I think it did otherwise also other errors should be visible). To be sure.

If it did get an Access Token, then probably you did not get access to certain information/API’s because either you have not activated them or during sign-in you haven’t requested all corresponding claims.

Make sure all API’s are active and claimed.

Hi thanks for responding,

As I receive data, I assume my access token is working
I used this url to get the correct claims:

https://id.mercedes-benz.com/as/authori ... %20consent

and within the developer portal I have added the following products to my project:

Electric Vehicle Status
Fuel Status
Pay As You Drive Insurance
Vehicle Lock Status
Vehicle Status

all with the OAuth Credentials (Authorization Code Flow) and BYOCAR

looking into my latest logs I still get some errors know and then, however that is not everytime the data is being polled, and sometimes I get a 401, and other times a 502 error message...

2021-11-03 10:02:43.270 Error: Mercedes: Failed to perform GET request (401)!
2021-11-03 10:10:55.696 Error: Mercedes: Failed to perform GET request (502)!
2021-11-03 10:10:55.696 Error: Mercedes: Failed to get resource data odo.

so can anyone explain what is causing this?

[kiddigital]

Hi @K0enH,

Looking at the info provide, it looks you are doing everything correctly

So I took a look at my own logs and see exactly the same messages appearing. I see that some sensors are still frequently updated, but some are not.

Didn't spend the time (yet) to figure out if the sensors that are not update are related to 1 or more specific API's (Vehicle Lock Status, etc.), but it sure looks that way. I guess that some API's are not behaving as they should (unless Mercedes changed things that we are not yet aware of) or maybe the proxies in front are misbehaving or something along those lines.

Hopefully Mercedes does see these errors as well (they are the ones returning these response codes so they could/should, so hopefully @mbdeveloper is reading along ) and will react on it.

The API status does not show any issues at the moment.

[K0enH]

thanks for explaining @ kidigital!

are you also aware if the location status issue is still applicable?
eg the state device in domoticz only shows value (0) Not Home.
and read in this topic earlier that this was due to the fact that Mercedes was not providing the location correctly!?

[kiddigital]

Indeed, currently the API does not provide any location information. The Mercedes module uses the eVehicle framework which has a ‘Home’ location but that is not something that can be populated at the moment.

There is a feature request outstanding at Mercedes to at least provide the ‘area’ information (as one can currently define in the MercedesMe app). But if/when is not defined…

[Gianni]

can someone help me out

I still got this error

error ME.png (54.36 KiB) Viewed 2679 times

steps i did

register a app
Get client id en secret.
Go to the url with the client id
logged in with my account
Get a authentication code
Paste ID:Secret into domotoicz
PAste auth into domoticz

into Me settings remote retrevale is active

I already try 3 different auth codes

[kiddigital]

It seems that somehow the code is not accepted as a valid code.

Make sure you have activated all (5) API’s. Can you show a screenshot of the Mercedes Dev portal with all your licenses? (Like at the top of this post)

[Gianni]

hello

here is a screenshot of the dev console.
I try to remove the spec module but cannot do this because it's still pending.

Try it with postman but also a connection refused

How does the url look like to get the token? Maybe something wrong with the claims?

[Gianni]

https://localhost/

[kiddigital]

That look like a valid response, but I meant the URL to start the login/token procedure.

[Gianni]

heeheh here you go

https://id.mercedes-benz.com/as/authori ... %20consent

[Gianni]

and this is my postman token config

You did not replace the clientid in the URL! This should be the client ID of the new project you just created.

[Gianni]

i replaced <client id> with my client id but i removed it here to post it

Hi
since a while I get these errors in the Domoticz log file
as you see, Battery level and others are working fine, but not all, like "vehiclelockstatus" :
vehiclelockstatus, is there in my mercedes-me console.
other stuff like automatic token refresh is working fine.

Hi,
I started to get these "403, Access has been denied!" messages since Jul 1.
It has continued from there on, I don't get any data to Domoticz.

At Jul1, first, some "Received 500/503, Service not available" for ten minutest, then few timeouts to requests.
After that, "Received 403" for pretty much everything that Domoticz tries to access from Mercedes server.

Then after minute or two, "Received 400/401", and automatic re-authorization happens.
re-authorization seems to be ok, "Login credentials Refresh successful."

But, after that, only "Received 403", it has continued after that.

I did manual re-authorization few times, re-authorization seem to be ok according to log message.
I also upgraded Domoticz to latest stable version, re-authorized again, again re-authorization seems to go ok.
But...."Received 403" continues.

There were message in Mercedes site that some reconfiguration happens 28-29 Jun.

Is Domoticz Mercedes Me Connect plugin still working ok for somebody?

[kiddigital]

Just checked and I still receive data, last data from a few hours ago.
