Plan format

The plan is one JSON object stored in .storage/fns_floorplan. The editor reads and writes it; you can also read it with fns_floorplan/plan/get and replace it with fns_floorplan/plan/save (Websocket API).

• Coordinates are metres, x to the right, z down.
• rev is the revision counter, managed by the integration; do not set it by hand.
• Rooms and items of the first floor carry no level.

Top level

Levels

Key	Type	Description
id	string	Id of the floor
