I haven’t mounted it to the wall yet. But it is plugged into a smart outlet, so that when the iPad reports low battery the outlet turns on, and turns off again after the iPad hits fully charged.
Occasionally the Home Assistant app becomes non-responsive and I have to force-quit and restart it. Other than that it’s a pretty decent kiosk solution. The capacitive touchscreen on the iPad is very responsive and I can fit a fair # of widgets on it. Deciding what should be “above the fold” and what’s below it is the hardest part!
