I’ve got a Tesla Powerwall that’s been doing something strange for the last couple of months.
I have a Netzero automation that sets the Powerwall backup reserve to 35% at 12:00am every night. That automation runs successfully.
However, just before 6:00am every morning, the Powerwall starts charging itself back up to 60%, effectively overriding the 35% reserve setting.
Nothing has changed in my Netzero automation, and this behaviour only started around two months ago.
Has anyone else experienced this? Is this due to a recent Tesla software update, an Energy Plan setting, or something else that’s now overriding Netzero?
Any advice on where to look would be greatly appreciated.
