What was the last working version of Home Assistant Core?

core-2024.5.4

What type of installation are you running?

Home Assistant Supervised

Integration causing the issue

Diagnostics information

No response

Example YAML snippet

No response

Anything in the logs that might be useful for us?

On init, the integration fails with this error message:

An unknown error occurred while connecting to Nissan: <class 'pycarwings2.pycarwings2.CarwingsError'>

Additional information

It is similar to the issue discussed in pycarwings2 Issue #46, suggesting that the bug is inherent to the pycarwings2 library rather than Home Assistant's integration of it.

• API stopped working: "The requested URL /api_v210707_NE/gdc/InitialApp_v2.php was not found on this server." filcole/pycarwings2#46

I'm having the same issue.

[mihaicristianpetrescu]

Same problem over here as well.

[RogMoe]

I think it has something to do with the latest HA update. I performed that update yesterday and only today I noticed that my Leaf was not (smart)charging. It needs the SoC to start charging. That's how I found out...
The app and their website do work as usual (slow but okay).

[josemi73]

Same problem, I updated tonight but I think that it was failing from before updating

[remuslazar]

@RogMoe this issue affects older HA releases as well, not being related to HA itself but to the pycarwings2 library. I was able to fix the root cause by updating the API endpoint address, see filcole/pycarwings2#47.

[RogMoe]

Yes, you're right. Just restored to HA core_2024.5.3 and that didn't solve the issue.

This may sound like a stupid question, but how is it going to be fixed? Do I need to do enything or stay put and wait for as long as it takes?

[remuslazar]

@RogMoe, the fix requires a new release of pycarwings2, which will also need to be integrated into the upcoming patch-level release of Home Assistant.

In the meantime, you can update your existing Home Assistant instance by following the instructions provided in this comment: filcole/pycarwings2#46 (comment).

I tried the fix and it did bring back the Nissan LEAF add-on but it seemed to break my GivTCP Add On. I guess I'll need to await the formal fix.

[Hairsy07]

Ignore my comment - bizarrely, at the same time that I was executing the suggestion, my router decided to change an IP address that it's never changed before.

[mihaicristianpetrescu]

UPDATE:
This is caused by latest HA Core update which reverted the URL back to older API version, updated it again and it's working.
Please push the latest URL to HA Core so that it won't revert itself back on future HA Core updates.

Applied the patch, worked for a while, not its broken yet again.

[epiniguin]

I applied the patch.
There is no a pycarwings2 error, but I still receive "An error occurred parsing response from server" from the Nissan Leaf component.
My car is Leaf 2016, the region is Bulgaria.
