CalDAV-native room booking for Nextcloud. Rooms appear as bookable resources in any calendar app — no separate booking interface needed.
- CalDAV Resources — Rooms show up in Nextcloud Calendar, Apple Calendar, Outlook, eM Client, Thunderbird

- Conflict detection — Automatic overlap checking, conflicting bookings are declined
- Permission system — Viewer / Booker / Manager roles per room, user and group based
- Room groups — Organize rooms into groups with shared permissions
- Availability rules — Restrict booking hours per room (e.g., weekdays 08:00–18:00)
- Booking horizon — Limit how far in advance rooms can be booked
- Email notifications — Booking confirmations, decline notices, approval requests with iCalendar attachments
- Per-room SMTP — Each room can have its own SMTP config (passwords encrypted via ICrypto)
- Custom room types — Define and manage room types (meeting room, studio, lecture hall, etc.)
- Public REST API — Bearer token API for external integrations (displays, kiosks, digital signage)
- CSV Import/Export — Bulk room management, with MS365/Exchange format support
- Client compatibility — Fixes for iOS (CUTYPE=INDIVIDUAL) and eM Client (LOCATION-only booking)
