Info

This dynamic platform plugin allows control of Mercedes Me capable cars. At the moment it is only possible to get information like vehicle status, lock status, fuel status etc. If in the future the possibility of e.g. locking or unlocking the car becomes possible, this will also be implemented.

Any system capable of running Homebridge can be used to run homebridge-mercedesme. The only need is Mercedes Me capable car.

Installation instructions

After Homebridge has been installed:

sudo npm install -g homebridge-mercedesme@latest

First steps (obtain Client ID and Client Secret)

In order to use this plugin, you must first log in with your Mercedes Me account on Mercedes Developer. After logging in go to Console and press on Add new app if you dont have already an existing app for this plugin.

Enter Application Name (e.g. Homebridge) Business Purposes (e.g. homebridge-mercedesme) and press Create

Now we need to add the API endpoints to our App.

1. Visit Vehicle Status API and press Get access.
2. Choose Bring your own car and press Next
3. Choose Standard and press Next
4. Choose your existing app and press Next
5. On Edit Application leave everything as it is and press Submit

Congratulation. Now you have added the Vehicle Status endpoint to your app. You need also to add Lock Status endpoint, Pay as your drive endpoint, Electric Vehicle Status endpoint and Fuel status endpoint to your app by following the above steps.

Requested endpoints:

• [x] Vehicle Status (added above)
• [ ] Lock Status
• [ ] Fuel Status
• [ ] Electric Vehicle Status
• [ ] Pay as you drive

Once you have added all the API endpoints to your application, visit Console again. You should see your Client ID, Client Secret and Redirect Url.

Important

Add your Config UI X ip address with port as your Redirect Url (eg http://192.168.178.11:8080). If you have multiple ip addresses to your config ui x, please add them all as redirect uri !

Copy your Client ID and Client Secret and put it in your config.json (Config UI > Plugins > Homebridge Mercedesme Settings > Client ID/Client Secret)

First start

The Version 2 is completely new designed. It supports Config UI X Plugin UI Utils and is full integrated in your homebridge system via Config UI X. The custom config will guide you through the process! Generating or refreshing access token was never easier! Below you can see how easy it is to create, edit or delete a new car for the config.json using the custom user interface. To use the custom user interface you need at least homebridge-config-ui-x v4.34.0!

Please setup your config in Config UI X under Plugins > Homebridge Mercedes Me > Settings.
