Describe the issue

Hi

I noticed that the field "time_to_full_charge" might have changed in the past couple of days. Before, this was showing the expected time by when the charging will be completed in the format of "2025-02-12T20:12:29+00:00". I noticed, that with potentially some recent changes on Teslemetry(?) this is wrong. The API result now is "time_to_full_charge": 9.25 which is probably 9hrs 15 Minutes. I think the integration however treats this as 9mins15 seconds? Do you see the same? Strangely enought, "Time_to_arrival" is still correct. I was trying to find if the API has changed but failed to find an answer.

It's the first time I am raising an issue on Github. Apologies if i missed something.

Reproduction steps

1. Obtain API key from teslemetry
2. install Teslemetry HACS integration
3. Start charging the vehicle
4. Check if "time_to_full_charge" shows the correct result in HA.

In the custom integration there are two entities, time at full charge and time to full charge. One shows the time, the other shows the number of hours.

Do you also have both, and which do you think changed?

[adultano]

Thanks for the quick response - however time AT full charge i dont see. i only have time TO full charge and that's where i think it changed.

maybe to clarfify: Below you see the result on teslemetry:
"time_to_full_charge": 8.25,
"timestamp": 1739396918069,
"trip_charging": false,
"usable_battery_level": 40,

8.25 which matches the 8hrs15minutes which i see in the official tesla app. however in HA i see:

which is in fact 9minutes from now. Maybe I am just being stupid. But something must have changed

[adultano]

So my guess is- but I am completely unqualified to confirm this - maybe this field before was sending minutes only, i.e. 495 minutes, and now instead it reports it as hours, i.e. 8.25. mathematically this would match my findings.

Meanwhile - a huge thanks for all your hard work!

Yes, I believe you are right about the minutes vs hours thing. I thought I had already fixed that but seemly not.

[adultano]

Thank you so much - at least I read the information not entirely wrong then. Take your time to fix it, I've done some workaround in the meantime. And thanks again so much. Let me know if I can "buy you a coffee" in some way.
