Good to hear. Thank you.

Hi,

I finally updatet my Domoticz so i was able to test it. It worked Yesterday, but now i get:

2021-01-22 13:49:40.866 Status: Mercedes: Executing command: Get All states

2021-01-22 13:49:42.058 Error: Mercedes: Timeout requesting Get All states. Will retry.

And sometimes:

2021-01-22 13:52:12.908 Status: Received unhandled HTTP returncode 28 !

Any ideas?

403 code means Unauthorized but I would expect that this is detected and the module tries to re-authenticatie.

Code 28 is a Domoticz (actually from the Curl library) internal time-out meaning Domoticz, and in this case the MercedesMe module, did not receive a response to its request to Mercedes.

I have seen those myself as well and looking into ways to deal better with these (too) long response times.

But for the 403; try to disable the module (so the worker stops) and re-enable it. The module will start again by doing the authentication again.

Hm.. typical. The first step confirms that you have a valid user as you are able to login and getting a new token.

But than the following calls fail because you are not authorized.

This could be because you did not receive authorization for all claims.

Which API’s do you have activated in the Mercedes Console? You should have 5 API’s. Also which list of claims did you pass initially to get your token?

I have been looking into your issue and I found the same problem. So it is not you

It seems that at the moment (24 Jan 2021) the 'Electric Vehicle Status' API always gives an 403 - Access Denied although you have valid credentials. I think a problem at API end at Mercedes (@mbdeveloper , is there a problem?)

Currently looking into ways to handle this better if possible, so a PR might follow.

Hope it gets resolved soon...

Posted: **Monday 25 January 2021 13:14**

Created a PR, which has been merged into Development. A prebuild Beta is available, look for build 12888 or higher.

This small update will ensure that in case of a 403 - Access Denied error on one of the API's, even after succesfull Identification and Authorization (meaning you have been granted access to the API as per claim request), the processing of other available data is continued and not aborted anymore.

Posted: **Monday 25 January 2021 21:47**

Thanks!

I use this on Windows and this Beta 12888 also has another problem. When you click on Settings it crashes Domoticz.
See https://github.com/domoticz/domoticz/issues/4593

This is what i get with the lastets Beta in the status log every minute:

Should it be that busy every minute?

Posted: **Monday 25 January 2021 21:54**

Normal interval is every 10 minutes, but you can specify this in the settings (when it works).

But I have the same issues and it seems that there is a problem at Daimler

I have been in contact with them and they said that they are looking into it. (Problem became a little bigger, not only some 403’s on EV but now general gateway time-outs).

Hopefully they fix it soon...

Dear all,
sorry, but again we have trouble with some technical issues on a subsequent backend system. It's a new kind of problem.
The team is working on it. We already test some fast bug fixes and hopefully, we can fix it soon.

Hi I've installed the latest stable release (2021.1) and I've added Mercedes Me as Hardware. I've now several new devices added as well as one can expect. In my log I get the following information:
Status: GLA180: Worker started...

Status: GLA180: Car awake detection: Car awake
Status: GLA180: Executing command: Get All states
Status: GLA180: Received (204) No Content.. likely because of no activity/updates in the last 12 hours!

The last two message Get all states and Received (204) are recurring with the set interval. In my Mercedes app on my phone I have newer data than I have received in the devices in Domoticz. Anyone with the same issues?

Posted: **Friday 23 April 2021 7:05**

The BYOcar API’s only provide data when there is ‘new’ data meaning the data has to have been updated in the last 12 hours.

This is a ‘problem’ when you instantiate the Domoticz module and no new data is available. It will generate a few basic devices (but not all) but no data.

Easiest way to test is to drive around the block for a few minutes and open/close all doors, windows, etc.

Make sure you have ‘enable new hardware/sensors’ as the module will try to add new sensor for each reading it can successfully do (if add custom sensors is turned on in the module settings).

Also good to know that the official MercedesMe app uses a different API than the BYOcar API’s and therefore might have other/newer/different data.

This ‘issue’ is something Mercedes said they are working on to ensure that the BYOcar API’s have the same data.

Hope the above clarifies a few things

Happy driving...

Hi,

Thank you for your response. The data today has been updated. Strange though that my car was used yesterday morning, so the data should have been updated. Nevertheless, even when the information is somewhat outdated it is still nice to have it in my dashboard.

Posted: **Thursday 13 May 2021 17:12**

Hi,

I have installed the last version of Domoticz 2021.1 on a Raspberry PI and tried to have a connection with my Mercedes, following the explanation in this post.
I have created a project on the site of Mercedes Developper and the 5 BYOCAR products.
I have given the authorization.
I have also created a hardware Mercedes Me Connect in Domoticz with as username [client ID]:[client secret] and as password the token I found in the the title bar of the web page opened after the authorization process.

When I try to connect to Mercedes, I have the following log messages:
