Adding XC40 2019 Diesel fails

[thomasddn]

I am getting a problem adding a second car. My first car (V90 XC 2021) works fine and the level of information is great! When I do 'add entry' for the second car (XC40 2019 Diesel) it fails to initialise. It keeps retrying so I have disabled it. The system log has the following error info (I have removed the VIN and replaced with '*'):

Logger: custom_components.volvo_cars.coordinator

The above exception was the direct cause of the following exception:

I can see both cars in the app and can switch between them etc. I am using the same Volvo ID login details for both entries, I am using the same API key for both vehicles. The VIN is obviously different and the Friendly name is different.

I am doing something wrong?

Can you:

• Remove the faulty entry
• Enable debug logging (how-to)
• Add the XC40 again
• Disable debug logging
• Upload the log (remove VIN from log)

Done, if you need more info - let met know :)

I see what the issue is: "No relationship to UUID".

You probably don't have access to that car with the specified account. Do you see both cars on https://www.volvocars.com/uk/account/my-cars/?

Forgot to say this, and it's not the cause of the problem, but don't use the same API key for both cars, unless you'll set the update interval to a larger value. You can create multiple API keys.

So I restarted HA so that the log would be easier to clean up.

I deleted the previous XC40 entry, disabled the V90 entry and enabled debug logging.

I then added the XC40 entry and it worked!

I then re-enabled the V90 entry and that's working too.

I did not see your comments about UUID before doing this.

So I guess what I should do is delete the XC40 again, set up a new API key and then re-add the XC40 with the new API key?

I have the debug log if you would like it but I guess it will show it going through without any problem?

That is one option.

The second option is to set a higher update interval on both entries. Look for the "Data update interval" entity of both cars. In a next release there will be an option to change the API key without needing to re-configure the entry. Then you could lower the interval again.

I have the debug log

I don't need it for now.
