We got PTO from our utility late yesterday and turned on our system (solar roof + powerwalls) today, but the "power flow" diagram in the app still looks the same. It shows Grid, Home, and Powerwall, but no roof. I can tell that the roof is producing, because we're getting negative values in our energy usage from the grid, but there's no roof icon in the app. Is this normal? Does it take time for things to show up in the app?
