The classic door panel without the proprietary hardware: a tablet or small screen by the door shows whether the room is free or busy right now, the current booking and what comes next, green when free and red when busy. Paste the iCal link of the room calendar and that is it.
Free plan, no credit card required. Paid plans from €5/month. Plugin version v1.1.

Green when free, red when busy, with the minutes until the next change.
What is happening in the room and what follows.
Google Workspace, Microsoft 365 or Exchange, through the iCal link.
Every door gets its own panel, all managed from one dashboard.
Google Workspace: the room resource's secret iCal address. Microsoft 365: publish the room calendar and copy the ICS link.
The panel shows the room name, the clock and the bookings.
A tablet in a stand or a small screen with a Pi opens the player URL and stays on the panel.
The panel reads the room calendar you paste and shows the booking titles on the door. Give the room calendar a title policy that suits a corridor, or use a calendar that hides details.
TVpilot turns the hardware you have into a managed screen: a Raspberry Pi with one command, a Fire TV Stick or Android TV, or simply the browser of a smart TV. One player URL per screen, managed from the dashboard.
Every plugin is included in every plan. You pay for screens, not for integrations.
Start on the free plan and stay there as long as you like. No credit card, no trial clock.
Any iPad or Android tablet in a stand, opened on the player URL. On an iPad use Guided Access to lock it to the panel.
No. The panel shows the calendar; booking stays in Google or Microsoft. That keeps the panel reliable and cheap.
The feed is refreshed automatically; most calendar providers export changes within a few minutes.
One widget per room, as many as you have screens for.
A door panel that shows whether a room is free or busy right now, the current booking and what is next, straight from the room calendar. Paste the iCal link of Google Workspace, Microsoft 365 or Exchange. Free plan available.
