Wrong timezone for TOU in charging stats?

[frankvb]

Anyone who has entered a schedule for a time-of-use electricity cost in the Tesla app? I noticed that even though I only charge between midnight and 6AM (super off-peak rate) the app thinks that I start charging the previous day. Apparently the timezone it uses for determining the rate is incorrect.

I'm certain something is wrong as it registers some kWh of charging the day before I charge (I only charge once per week so quite sure about this). It's showing 9 kWh the previous day which would be one hour. Maybe it's confused by daylight savings time.

same here the app shows 32% peak charging (increasing) and I only charge off-peak (9pm-7am)

I just found out my problem is a bug with winter/summer time - I just reduced the peak charging time by 1 hour and now it is 100% off-peak charging as it should be. so it is a bug in the tesla app.

Yes that's exactly what I did as well.

This is probably a DST bug? I'm in Michigan and I have the same issue.

Yes that's exactly what it is. Didn't realise it was not timezone but just daylight savings time when I started this post.

seems to be fixed now

Anyone have this problem pop up again? My TOU shows charging at 37% at peak hours when I only schedule charging for off peak or mid peak.

Yes same issue popped up for me as well since DST change. It moved 9kw of charging to previous day since I bought the car. App used to show 100% super off peak charging now it’s 78%.

Yes, came back like clockwork this year again. My TOU schedule is correct, gateway is on the correct time (based on home use time stamps), but charging stats are logging an hour early and categorizing as mid-peak when it should be off-peak.

I'm a new owner and just noticed this issue a few days ago. I hope this is just a logging error instead of that the car actually starts charging before 12AM.

Issue seems to be resolved now. Peak % for March and last 31 days now showing 0%.

I know SDG&E used to actually be out of sync with DST changes for a couple of years after they changed the dates we change our clocks. The TOU rates would stay on standard time until the old switchover date in the spring and vice versa in the fall. I'd have to actually change the timer in the EVSE to compensate, so I used to just start at 1AM rather than worry about it. However, they finally fixed that.

Not fixed for me. Having to start charging at 1:00a instead of 12:00mn in order to have entire session logged on a single day.

Have you tried checking your Charge Stats and updating your charging plan details in the app? I noticed that even though the pulldown for my electricity provider plan is there and for the most part the details are correct for my TOU rate plan, I noticed the rate was like a cent off and they didnt split my summer months peak/mid peak rates between weekdays and weekends correctly so I had to update that. I think the Tesla keys off of what your have under your power plan set for "off-peak" and "super off-peak" hours when charging so that is why you may have that inconsistencies to ensure it is set to the correct off-peak and super off-peak hours.
