Could you test this out @toraidl?

Sure I can test it @cdnninja

Two issues encountered:

@cdnninja I'm wondering if it's possible to test the hyundai_kia_connect_api locally with kia_uvo custom_componment? By testing locally, I can quickly troubleshoot issues.

[cdnninja]

It's a bit of a pain but can be done. I'll grab the link on instructions when I can.

I suspect the issue is related to line 289 of the api file. All times need a time zone or the comparison will fail to current time. Make sure the value coming from the api has a tz and is being parsed correctly to ensure python recognizes it.

[toraidl]

It seems like correct?

The function get_last_updated_at(self, value) -> dt.datetime on line 210 returns the datetime format: 2023-05-04 14:47:58+08:00
whereas line 294 vehicle.last_updated_at = dt.datetime.now(self.data_timezone) return format like this: 2023-05-05 09:36:55.362564+08:00

[toraidl]

I believe I have identified the problem and have submitted a PR to the API repository.
After testing it locally, it appears the issue has been resolved.

@toraidl Thanks for all the work on this! I will merge this now.
