Cant remote start the engine

[lagge78]

What happened?

Hello!
I try to start the engine on a XC60 PHEV MY24 with the remote start button from the integration but I get an error all the time.
I get an popup in the button of Home Assistant that states:
"Couldn't perform the action button/press, unknown error"

I saw this in the debug log (complete below):
aiohttp.client_exceptions.ClientResponseError: 403, message='Forbidden', url='https://api.volvocars.com/connected-vehicle/v2/vehicles/YV1UZH5V3R1793016/commands/engine-start'

I have the latest 1.0.2 release of the integration and Home Assistant is on 25.1.2.

Any ideas? All other entities works, like the climatization start has no problem.

It's a shortcoming of the public Volvo API. We need to use a certain scope, but we're not allowed to use that scope. I mailed to Volvo mid December, but no response so far.

[thomasddn]

Engine buttons will be removed in the next release.

Hi
Is this issue impact also climate star/stop button
I don't have this buttons on my XC60

[thomasddn]

@snp88 Your car probably doesn't support the climate endpoint.

[gacopl]

can you give more details, i could swore volvo2mqtt had ability to start, also developer api docs mention engine start stop

[thomasddn]

The API indeed mentions the start/stop engine, but it requires the use of a certain scope. However, the API user I’m using (the same as volvo2mqtt) is not allowed to use that scope. This means we’re unable to use that endpoint.
