Thanks for the replies and apologies for not following up. It was a busy weekend. Travel with the MY was great and the navigation took me to two easy-to-access and uncrowded superchargers.
Over the weekend I didn't look at this much because I lost access to some app functionality and didn't dare mess with it while travelling. Roughly the sequence was: Lost access to Charge on Solar Settings -> Various levels of clearing app data ending with a full reinstall -> Was told to set up Phone Key -> the process kept telling me I wasn't close enough to the car, even when sitting the the driver's seat. Various reboots, placements of the key card, and changes to Bluetooth settings made no difference at all.
@ATPMSD I now know not to worry about an occasional 8 hours at 100%. Thanks. As for settings, I thought I followed the scheduled departure instructions, but I can't check my settings after all the changes described above. I have had the car set to charge at 2 AM if it is below 60% and then charge to 80% if there is enough solar. The departure setting pushed the charge time back to midnight, which seemed odd. I suppose in the future I'll just shift the charging start time as you suggest, hand-adjust the thresholds, and ignore the scheduled departure feature, which seems to confuse more people than it pleases.
@gtae07 I don't normally leave in the morning. Also, I don't want to "fake" the TOU power information because my home makes use of the correct information. It looks like I could fake it for the car and leave the home tab at correct values, but that seems like a pretty bad hack. Your comment about "finished charging just before the earlier of the off-peak end time or the departure time" sounds like exactly what I wanted, but it's not what happened. It finished charging about 8 hours before departure and 12 hours before the end of off-peak. Maybe I need to try again.
I have now reinstalled the app again and regained the ability to set up the phone key, which means I now have full control over the car again. The 2024.14.9 software update is installing right now. Perhaps some software glitches will be fixed, or I won't make the same mistakes if I try again. Next time I'll take notes.
I have been super impressed with how the app works with my solar panels and power walls. The basic car features looked good at first, but other features seem fragile.
For the record, here's what it took to restore Phone Key capability. I don't know that every step is required, but I had tried most parts of this before without success.
Without testing or using the apps or car between steps:
- Force stop Tesla
- Clear all data
- Uninstall
- Force stop Tessie
- Clear all data
- Uninstall
- Reboot car display using steering wheel buttons
- Reinstall Tesla App
- Set up phone key when prompted. It was quick and painless.
I haven't reinstalled Tessie. It's probably fine, but I wanted to remove as many variables as possible.
