That doesn’t look right, it looks like this for me (NL/EU region):
Were you able to log in successfully?
Yes - the log in step was successfully and I was surprised to have zero devices/entities under the integration. And under logs I have this error:
Logger: custom_components.mbapi2020.client

Error with the websocket connection: Received message 257:None is not bytes

Looks like something you should report to the developer
Never mind, I’m seeing the same issue at the moment. Probably a backend issue at Mercedes

Hi @kilters,
thanks for this feedback regarding this problem. The components waits for a full update for all registered cars before creating the sensors. I cant test this scenario and adopt the code. Let me know via a private message if you would like to share some internals so that I can check if I can handle this edge case.

Hi,
the error is expected currently. Normally, the websocket connection is recreated after this error. Do you get updates after the error?
I have to work on the websocket connections, but this takes longer at testing takes hours until the server closes the connection.

Hi,
to be open, I’m not sure it what countries this integration is working. Based the featureflags the app receives from MB it looks like that the app (and therefore this integration) is tested internally in the US.
I do not expect a solution for 2017 US-cars soon. My last integration (GitHub - ReneNulschDE/mbapipy: MercedesME platform as a Custom Component for Home Assistant.) works with US cars starting 2019.
Sorry, looks like that I will not have solution to this.

Hi,
As I wrote, I assume the component does not work for Noram currently. Please check https://github.com/ReneNulschDE/mbapipy if your car is 2019 or newer.

Hi,
looks like this is an older car with a Bluetooth adapter. Right? If so, please do not expect any support with this component. But you can take a look on IOBROKER. This Home-Automation system has an integration to the Bluetooth adapter integration created by https://github.com/TA2k/. (Yes, we worked together behind the scenes and shared our knowledge)
If you would like to build an integration, feel free to send a PR on my github account.

Perhaps it’s possible to use a websocket proxy for testing? Should make it easier to simulate the connection being dropped or closing.
I am so thankfull @ReneNulschDE is working on this!
Based on some inspiration, code and images from this forum I created this picture elements card.
- I used this code, to create sensors out of the attributes from the integration
NOTE: adjust it with your own sensors ofcourse!!
## this yaml file creates seperate sensors in HA for the attributes derrived from the Benz sensors. Credits to Rene Nulsch for creating this awesome MercedesMe integration!
## I am not a programmer, this is all derrived from everywhere around the forum, re-use of images, inspiration and code.
## For me, having a splitted Home Assistant config I created this yaml file, named it mercedessensor.yaml and placed it in my sensors directory within home assistant
## I guess it can be part of your configuration file as well.....

- upload this picture to your www directory of HA. I made it transparant.
download PNG here: https://ibb.co/vYJmQ0j
- next I used the following yaml in the picture elements card.
## This is the card yaml, based on a picture-elements card. just create one in yourlovelace dashboard and copy and past in your card.

Enjoy playing around…moving around the sensors can create sometimes headaches :-). I would love to see more variants on this. I am not happy with the lock status 2, but since my programming skills are limited…it takes some time to figure thinks out hehehehe.

I will try to keep an eye on it.

Im somewhat new to HACS but would it be possible to convert something like this into a hacs frontend component?
Also is that even possible in general?
Im guessing the missing sensors would cause problems, right?
Awesome work @ReneNulschDE, I guess we will have to sign up to Mercedes me and try it!
Happy New Year everyone 
I am from the Netherlands, and this is the app I use:
I can login on the website of Mercedes.me and see my car, and some basic information.
The app is really minimal, not as much information as for the big brother cars… but battery level, how much milage left and total milage is there.
Hi, this app is using a different API set. Sorry, but I can’t help here. However, maybe some other devs in this thread could help.
Working brilliantly, thank you @ReneNulschDE!
I normally log in with phone number, which actually did work (sent me a code), but errored when entering the code into the integration setup.
I logged in with email instead, which of course worked.
This is beautiful, got it up and running! Gunna customise.
Could I ask you upload the transparent image somewhere? It only lets me download as a jpeg and loses the transparency.
Thanks a lot!
Much appreciated!
