My Tesla Energy Gateway is now on version 23.4.2. And I just noticed that it's not executing Time Based Control like it used to.
Previously, my batteries would only discharge from 3pm to midnight every day. This is because those times are the EV2-A shoulder or peak times, where energy costs more from the utility. I don't use "self powered" mode, I have exclusively used "time based control." Since the off-peak pricing was the cheapest, the time based control knew to use the grid as much as possible during off-peak. Solar generation would be prioritized to be stored in the batteries instead of being used in the home.
But now, the Powerwalls will still discharge during that 3pm to midnight window, but then they'll also discharge again after midnight if I'm charging an EV. You can see in the screenshots below, I have two Teslas... one scheduled to charge starting 1:00am and the other at 1:30am. When the EV charging started, the home's total consumption rose to 16 kW (67A @ 240).
Only 10 kW was coming from the grid, and the Powerwalls discharged at 6 kW.
The problem is this battery discharge rapidly dropped the SoC well below the 30% backup/reserve cutoff I had specified. You can see the "dark green" base layer on the Powerwall SOC chart. That dark band is supposed to be the reserve. I don't know what is causing this, but Tesla seems to indicate things are working normally? So what else can I try to do (besides not charging an EV).
