Which home assistant system are you using?
MG / SAIC - Custom Integration or the SAIC MQTT Gateway (Python) addon?

I'm using the MG/SAIC - Custom Integration .. just now trying to use the Phyton one ...

I found this guide to installation very helpful:

I managed to install the integration. To succeed, you’ve got to do some things Add a user Install the MQTT broker Install the MG integration Fill in your credentials Add a user click your name select advanced mode then click Settings → People → Users Add a user You will need the name and...

Just set up another Home Assistant phone dashboard for my wife to use. Only image I could find isn't really her specific model but it's close enough (same colour).

I copied someone else's idea from a forum somewhere and adapted it. Will need the mushroom cards added to your system.

I just grabbed an overhead image of a car from googling, saved it into the HA files section where your images are kept, and overlayed some data on that.

It sits in a panel/single card dashboard. Looks not so good on a computer screen but works well on a phone screen, which it this dashboard's purpose.

Play round with the top and left position % numbers to move the little info cards about to fit your own example. They operate as coordinates from the top left corner. IOW 0% left + 0% top = top left corner, 100% left + 100% right = bottom right corner.

yaml (replace the "xxxxx" sensors with those for your vehicle):

@wattmatters I just added your gauge to one of my dashboards:

Showed it to my other half, and then showed her the code.

I copied someone else's idea from a forum somewhere and adapted it. Will need the mushroom cards added to your system.

I just grabbed an overhead image of a car from googling, saved it into the HA files section where your images are kept, and overlayed some data on that.

It sits in a panel/single card dashboard. Looks not so good on a computer screen but works well on a phone screen, which it this dashboard's purpose.

Play round with the top and left position % numbers to move the little info cards about to fit your own example. They operate as coordinates from the top left corner. IOW 0% left + 0% top = top left corner, 100% left + 100% right = bottom right corner.

there's something wrong with my account .. it started since last Saturday when I can't connect to the car .. then on Sunday, I can't login to the app using my account.
So I initiate the binding procedure, wait for 72 hours (which was a few minutes ago) and rebind with the car ...

Now I can login to the app, but I can't refresh the status of the car The apps says that the last update was last Sunday ..

also now I need to login using my phone number where before I can use my email address ..

and I still can't login using the HA integration (it says, wrong password) ..

Try setting up the MQTT add on. Follow the guide I suggested to you in an earlier post.

I can see the VIN of the car, so I know it's connected .. although I don't see the stats (batt SOC, etc)

I think it's much more powerful than the custom integration.

time to adjust all of the automation and cards I've made ...

Great!
It's also worth mentioning that the custom integration is no longer being maintained, whereas the MQTT system is. (There have been several updates quite recently.)

yea .. I just read that the original maintainer no longer has the car ...

btw .. if I understand correctly, we can use this to send our data to ABRP right ? are you using it ?

gwatuk · Wednesday at 6:58 PM

Sorry - don't know anything about that. You should ask about that on the home assistant forum.

MG Motor Mg5 Electric Car Integration

Is anyone successfully using the ABRP part of the integration ? I have the abrp_user_token populated but am not seeing battery level updated in the app.

Yes, I have that set up, except I don't use ABRP much.

do you enable "PUBLISH_RAW_ABRP_DATA_ENABLED" what difference does it make ?

Mine is set to false. My ABRP is still updated with my car's actual SOC.

Has Anyone played around with HomeASSISTANT addon for the MG4 ???
