Hotels and B&Bs

A viewport in the lobby gives guests breakfast times, the Wi-Fi and what's on today. One on a room door says Please do not disturb, so housekeeping doesn't have to knock.

A hotel lobby board — The lobby: breakfast, the Wi-Fi to scan, the weather and what's on today

A room door sign — A room door: *Please do not disturb*, only while it's on

The case for Switchboard

Fewer questions at the desk. Breakfast times, the Wi-Fi and today’s events are on the wall, so staff aren’t asked them all day.
No reprinting. The wine tasting moves to 18:00? Change the calendar and every board shows it.
A door sign that can’t fall off. Do not disturb comes from a toggle in Home Assistant, set from a switch in the room or the Home Assistant app, and housekeeping sees it without knocking.
Looks right in a nice building. No glowing screen and no cable in a listed hallway. Months between charges.
One remote per room that guests understand. The lights, heating and TV in plain English, with the Wi-Fi on it too. See Holiday lets and guest rooms.

Setting it up

The lobby: Message, Guest Wi-Fi and another Message on the left; Weather and a Calendar on the right.
The door: a large red Message shown only while input_boolean.dnd is on, and the room number.

Setting Do not disturb with the viewport’s own buttons is planned: today it comes from Home Assistant. See Viewport layouts.
