When working normally, Powerwalls respond to app changes only once an hour. This seems to be intentional on Tesla's part, because if you use the local setup wizard, the Powerwalls will happily change modes immediately. My speculation is that Tesla did this to discourage users from making manual changes because they would like to have more control over the Powerwalls themselves. I think this might make it easier for them to offer grid stabilization services later on.
I'm actually fine with that. They just need to make the Powerwall act consistent. It should go into standby mode during "off peak" when in "cost savings mode." Sometime it does, sometimes it does not. Tesla Level 2 has told me that it should always go into standby mode in that case, but there is a problem with the firmware.
The 1st L2 rep I talked to placed a "fix" into my system and said that should correct things. It made things better, but did not fix the intermittent issue. He also said that there is new firmware coming out that will fix it. However, when I talked to the next support personnel, she did not have any records for what the 1st rep did in my tracking number. Now, I am waiting for the callback.
