I have a "free nights" (8pm-5am) plan, so I'm trying to get my system to only use the grid to power my house during those hours. For the past few weeks I've been manually switching to "backup only" at 8pm and then manually switching to "Advanced/Balanced" at 5am. That works, but I was hoping to get the system to do it automatically, so I've been leaving it on "Advanced / Cost Saving" for the past few days.
The system has been correctly switching the Powerwalls off at 8pm and drawing from the grid instead, but it's been switching from the grid back to the Powerwalls around 2:30-3:00am, when I still have 2-2.5 hours of free grid power left. Any idea why it's doing this? I've correctly defined the "peak" and "off-peak" hours in the app, and my plan has no "shoulder" times - just "peak" from 5a-8p and "off-peak" from 8p-5a. I've included pictures of the Powerwall usage for yesterday and today.
