**Room grid** provides an overview of up to 9 room resources, by displaying information about the current occupancy state of each room, its location and room name, and the time until the occupancy state changes.

Meeting subject is also displayed by default, but can be hidden if needed. If you wish to learn how, see [How to show/hide the meeting subject and organizer on your Joan devices](/help/joan-devices/how-to-show-hide-the-meeting-subject-and-organizer-on-your-joan-devices).

All of these features make the **Room Grid** a great functionality for a Joan 13 device located in the lobby of your office space.

**Features:**

- Up to 9 room resources
- Room availability and location
- Current meeting subject
- Time until the room status changes
