Methods for polling vehicle status, not diagnostics

[natereprogle]

I'm not sure if this is even possible (And if not, I'm not complaining since OnStar doesn't even provide public APIs to begin with), but is there any way to poll vehicle status? I know it's easy to send commands to the vehicle, but I wonder if it's possible to check the status of the vehicle. For example, can you check if it's locked or unlocked? Can you check how many minutes are remaining on the remote start timer? Feel free to answer if/when you get the chance, thanks so much for the work you've done with this!

Great work on this library. I'm using the NodeRed onstar2 integration and it works wonderfully.

I was looking under the diagnostics node but could not find an option to get the door lock state. Like OP, I'm not complaining just second'ing the request for door lock status!

Thanks again.

Commenting to see if any one was able to find way to get door lock status

I ended up abandoning OnStar integration with HA. It was just too cumbersome to work with; I decided to use the MyGMC app which has all the statuses.

You have door status from MyGMC ? Ex. if door is unlocked, etc ?

Temporarily, but Yes. When I issue a lock command, it shows “sent” and then “locked”. The “locked” status only shows after issuing a “Lock” command and then disappears.

You may be able to query the status of the vehicle every 5 minutes and then create a sensor based on the return result. Not sure but I imagine that the MyGMG app is doing something similar. I only say that because it only reports locked after issuing a lock command.

Going back to my earlier comment; it’s just too cumbersome to work with… case in point.

If you really wanted to get clever, you could MITM your device running the MyGMC, MyChevy, etc. then monitor the calls to see what the cloud service is returning.

The MITM is not outside of my expertise but deciphering the return result from the service definitely is…

I tested with MITM, and when OnStar return the "completion status", the button on the application change for few seconds, it only visual.

Since about 2 weeks, I captured all commands (start/startCancel, lock/unlock Door/Trunk, status, etc) sent/receive for about 250 vehicles (Bolt/Equinox EV/Blazer EV) right now and with my analysis, it not something that is "recorded"

The service may just be issuing the command and relying on the vehicle to process the request without any actual status/state output

I’m guessing it just flashes Locked/Unlocked when the vehicle reports that it received the command regardless of whether it actually locks.
