Area Purpose and Decay Behaviour¶
The integration lets you assign an Area Purpose to each instance. The purpose describes how the room is typically used and determines a sensible default for the probability decay speed.
Selecting a purpose automatically sets the Decay Half Life – the time it takes for the occupancy probability to halve when no new activity occurs. You can still override this value in the options flow if required.
| Purpose | Description | Default Half Life (s) |
|---|---|---|
| Passageway | Short transit spaces such as hallways or landings. Evidence fades very quickly. | 60 |
| Utility | Functional rooms like laundries or boot rooms. | 120 |
| Food‑Prep | Kitchen work zones. | 300 |
| Eating | Dining or breakfast areas. | 600 |
| Working / Studying | Offices or desks. | 600 |
| Social | Living rooms or play areas. | 720 |
| Relaxing | Lounges or reading nooks. | 900 |
| Sleeping | Bedrooms and similar spaces. | 1800 |
The chosen purpose does not directly alter the Bayesian calculation beyond this decay timing. A shorter half life causes the probability to drop faster after activity stops; a longer half life keeps the area marked as occupied for longer.
