Occupancy sensors

Sensors tell which berths are physically occupied. Porto compares this state with the expected occupancy and helps you act: resell the berths of boats that are away, catch unregistered arrivals, check transit arrivals.

Devices

Sensori gathers berth states, alerts and proposals, devices, gateways and sources. A device is linked to a berth, a stretch of a dynamic area or a pedestal; on creation you get its key, shown once, to load on the sensor. Porto is not tied to a vendor: any sensor or gateway following the open protocol works.

Physical state

A berth becomes occupied or free only after agreeing readings (by default 2 readings or 5 minutes), so waves are not mistaken for an arrival. A silent sensor becomes “unknown”. Thresholds are changed in the sensor settings. The Sensori lens of the map shows free, occupied, discrepancies and sensors offline or with low battery.

Reconciliation

Situation	What Porto proposes
Berth occupied with no expected occupancy	unexpected occupied berth alert
Transit expected today and the berth becomes occupied	recording the arrival
Annual contract berth free for a long time	presence “away” and, if the contract allows it, releasing the nights
Released and resold berth occupied before the transit arrives	early return alert
Silent sensor or low battery	a maintenance task

Sensors propose, they do not decide: no reading changes contracts or occupancies without an operator’s confirmation. The only automatic effect, if you enable it, is on presence.

History and report

Each sensor’s history shows the physical state night by night compared with the contractual one; the Sensori report summarises discrepancies. Raw readings are kept for 30 days (configurable), then only state changes remain.
