My Power Wall 2 firmware stays in V1.29. From Tesla web site, the latest firmware is V1.31. How can I update to V1.31?
my powerwalls were installed about three weeks ago and i'm on V1.32 per the app.
if it's anything like their cars, they push the update to you and i don't believe you can upgrade on your own.
They push out the software as needed. If your configuration requires the new version it will automatically download and upgrade without you ever knowing. If you call their support line sometimes you can ask the Powerwall tech to push an update however they don't do that very often.
