get_charge_history/VEHICLE_CHARGE_HISTORY has timezone GMT-07

[jankratochvil]

Hello, the charging history shows different values than what the (Android) Tesla app shows me. That is apparently because the app shows bars/days according to my timezone midnight (CEST=GMT+02) but TeslaPy receives data with timestamps of GMT-07 (such as 1661410800) midnight. Do you have some recorded data from the Tesla app? I expect the app sends some extra header / JSON data specifying local timezone.

@jankratochvil Hi, unfortunately I don't know answer to your question, but I'm currently trying to use this endpoint and all I receive from it is an empty response along with a 200OK code:

GET https://owner-api.teslamotors.com/api/1/vehicles/{$id}/charge_history
X-Tesla-User-Agent: TeslaApp/4.12.1
User-Agent: River
Authorization: Bearer {$token}
Host: owner-api.teslamotors.com

{
    "response": "{}\n"
}

Can you explain how did you manage to get results from that endpoint?

[jankratochvil]

You need to replace the {$id} there, in my case: https://owner-api.teslamotors.com/api/1/vehicles/29342XXX0953/charge_history XXX are 3 digits. The {$token} also needs to be replaced.

@jankratochvil Yep, I replace them for real vehicle ID and a valid token, so I guess that's why I get a 200 OK response, but still the charging history remains empty. Well, I have to dig deeper, I guess. Thanks for your answer!

Do you get the graphical output from gui.py? I do. Then I added some debug output to TeslaPy files as I was porting it to: https://github.com/stevieb9/tesla-vehicle

@jankratochvil I have the same problem the gui.py doesn't render any data on charge history screen, only empty diagram. The response code is 200 and json is empty.

I have no output, just "response": "{}\n" because I am leasing my car. I am not the owner, just the driver, so this call doesn't work for me. I also have no recorded data from the Tesla App to see if there are any parameters that can set the time zone for the call. @jankratochvil can you share the output of the call, so I can validate the graphical output?

The Android app shows it correctly as its midnight is at real midnight. But gui.py gets it shifted. gui.py.txt contains for example:

                                                           'timestamp': {'seconds': 1660806000}},

Which is Arizona U.S. timezone.

$ TZ=US/Arizona    perl -MPOSIX -e 'print ctime 1660806000'
Thu Aug 18 00:00:00 2022
$ TZ=GMT           perl -MPOSIX -e 'print ctime 1660806000'
Thu Aug 18 07:00:00 2022
$ TZ=Europe/Prague perl -MPOSIX -e 'print ctime 1660806000'
Thu Aug 18 09:00:00 2022

It looks as it is really split by such U.S. timezone midnight as normally I charge in the morning (before 9am, from 50% to 90%) before driving and in the evening (to restore SoC back to 50%) which Tesla Android app correctly displays as a single big bar. But gui.py does show such day as two charging days.
