Wall panel

A screen for a tablet on the wall or a Shelly Wall Display: the clock, the weather, the doors and windows left open, big open and close buttons for each room's blinds with its temperature, and the heat pumps, valves and switches. It keeps the screen on while it's showing, and refreshes every 20 seconds.

Open it from Account, This device, Open the panel. Switch on Open on the panel there to have that device start on it instead of Home; the panel's leave button switches it back.

Sign in on the panel's browser with an account of its own, made for it by an admin, so removing the tablet is just removing that account. Sessions last as long as Admin, Access allows; set it to 30 days for a panel.

On a Shelly Wall Display, open the panel's address in its web browser or dashboard app, depending on its firmware.
