Meeting rooms

A viewport on a meeting-room door shows whether the room is free, until when, and what's next. Another by the lifts shows which rooms are free right now.

The case for Switchboard

No cabling, no drilling. Commercial room panels need power and network run to every door. A viewport goes on the glass with no cable and runs for months on a charge.
Reads from down the corridor. E-ink is clear in daylight and from an angle, and it doesn’t glow in a dark room during a presentation.
Works with the calendars you have. Google Workspace, Microsoft 365, iCloud and most others publish a calendar link. The server reads it, and the sign never sees the link.
No Home Assistant needed. An office with only room signs can run the server on its own.
Set up many at once. Paste the list of rooms from a spreadsheet and the server makes a sign for each. Staff need no training: the sign says Free until 14:00.
Pairs with a remote. A remote on the table runs the blinds and lights for a presentation, in plain words.
