This one is the reason. Hold on, I’ll fix it right away!

thomas_be · December 8, 2024, 12:43pm

@xti9 I just released v0.2.1 which should fix the issue. Can you try it please?

You might need to explicitly check for an update in HACS. Go to the Volvo Cars repo and click “Update information” in the context menu of the three dots. After that you should see a pending update in Settings.

xti9 · December 8, 2024, 1:35pm

ok that worked.

But now i get an error - same error i was getting when using vovlo2mqtt alone - for some reaosn i cannot get access to my vehicle. Any ideas?

This error originated from a custom integration.

Just a few sanity checks:

Is your car connected to your Volvo account?
Do you use the same account for the Developer portal?
Did it work before?
Is your location mentioned on https://developer.volvocars.com/terms-and-conditions/apis-supported-locations/?
From what year is your Volvo?

Can you enable debug logging while adding your car or reloading the current entry? I’m interested in the log lines with Request []:, Request [] status: and Request [] body:.

Disable debug logging and send these log lines.

jelmer · December 8, 2024, 4:14pm

Works for me, thanks for the update!

xti9 · December 9, 2024, 7:48am

Hi.

Yes car connected to volvo account (and app works well)
Yes same account for developer portal. Also tried with guthub account
Yes worked for a year (volvo2mqtt)
Yes
2024 xc40 recharge

See log:

thomas_be · December 9, 2024, 9:04am

I receive the same error (No relationship to UUID) when I use a random VIN. Can you triple check your VIN number and make sure there is no whitespace before and after the number?

If that is OK, then the link between your car and developer account might be broken somehow. Did you change anything in your account or car around the time volvo2mqtt stopped working?

You could also try to create a new API key.

xti9 · December 9, 2024, 11:08am

Yes somehow link is broken. I have checked VIN number and its correct. Also created new API and get same error. My only change is that a few months ago i re-configures the car to my Volvo ID. Not sure if this may have disturbed something, and the error now popped up only when the system reattempted the OTP.

Other than that i am totally lost.

thomas_be · December 9, 2024, 11:45am

You could try to completely delete your developer account and create a new one.

jelmer · December 9, 2024, 4:39pm

That could be hard because I can’t seem to be able to login to the Volvo Developer Portal for weeks…

thomas_be · December 9, 2024, 7:19pm

Yeah, using email & password does not seem to work. But I can login using my GitHub account, which is using the same email address as my Volvo ID (not sure if this is required).

xti9 · December 9, 2024, 8:25pm

Thank you very much for your continued support. Have also deleted developer account and logged in via github. Exactly same response. Is there any way to see which cars are linked to an account on the developer hub?

thomas_be · December 9, 2024, 9:16pm

You can go to Specification – Energy API | Volvo Cars Developer Portal and locate “try it out”. There you can choose “My Volvo ID”. Click on authorize.

When returning to that page, scroll down and try out the first API call. You’ll need to enter your VIN.

xti9 · December 10, 2024, 9:19am

Yep failure there too. Maybe i need to contact Volvo.

thomas_be · December 10, 2024, 9:48am

Do you see the same e-mail address as your developer account on this page: https://www.volvocars.com/uk/account/?

You should also see your car and the VIN on this page: https://www.volvocars.com/uk/account/my-cars/.

(I’ve taken UK links, but you can use your own country.)

EDIT: If nothing else helps, maybe it is indeed better to contact Volvo.

xti9 · December 10, 2024, 1:40pm

OK finally got it to work! Indeed the car was not showing in the page you mentioned. So i logged out of the app, re logged in and then re paired the car to the app.

Thanks for your help. Integration is great!

thiagobruch · December 10, 2024, 5:22pm

Hi @thomas_be

Thank you for this project.
I have a XC90 (regular gas - not hybrid) and I encountered an issue after configuring that in HA.

It appears that the code fails when trying to get a filed that my car does not have (batteryCapacityKWH)

Is the code for E-vehicles only?

Thank you.

thomas_be · December 10, 2024, 5:37pm

Hi! The exact same issue (for the same model ) has been created on my repo about an hour ago. I’m working on a fix and will push a release shortly!

thomas_be · December 10, 2024, 6:32pm

@thiagobruch Please try v0.2.2. You’ll need to click on “update information” on the Volvo Cars entry in HACS. You can find it in the context menu of the three dots. After that, you should receive an update notification in Settings. You might need to restart HA.
