That’s a real plan, thanks. Ordered trackers that report the strongest BLE transmitter, did the room mapping in the gateway, installed the solution in a test org. Walked into the «switchgear» (my office) with forbiddenZone set and got the Critical alarm in a few seconds. Customer accepted room-level once they saw it on the floor plan. The permit handling we’ll do by changing forbiddenZone through the API when a permit is issued.
