Structure & access

Organisation (tenant) — your whole account, and the hard data-isolation boundary: nothing crosses between organisations. → Projects & access
Project — an operational workspace inside your organisation, with its own assets, rules, dashboards, and reports. → Projects & access
Scope — the level a role grant applies at: organisation, project, or group. A member’s effective permissions are the union of their grants. → Projects & access
Asset group — a node in the region → zone → site tree that organises a project’s assets; status roll-ups and group-scoped rules walk this tree. → Assets & groups
Asset class — one of the four kinds an asset can be (water meter, pump station, reservoir, pressure point); it sets the asset’s icon, its metrics, and how rules can target it. → Assets & groups

Cadence — how often a sensor is expected to report. The staleness window is a multiple of it (roughly 6×). → Metrics & telemetry
Shadow — a sensor’s small live record of its last uplink time and latest signal/battery reading. It starts empty and “comes alive” on the first uplink. → Metrics & telemetry
Staleness / stale — the state of a sensor whose last reading is older than its staleness window. Staleness is what turns a quiet sensor offline. → Metrics & telemetry
Offline — a sensor that has gone stale (no uplink for its window). Raised automatically as an offline alert — the one alert nobody authors. → Alert rules
Primary metric — the headline reading a class of asset leads with: a reservoir → level, a meter → flow. → Metrics & telemetry
Diagnostics — battery and signal (RSSI / SNR): metrics about the sensor’s health, never counted as a reading of the water network. → Metric catalogue

Action Centre — a global right-side sheet that gathers every active alert across your portfolio, groups them by project and kind with prescriptive guidance, and lets you acknowledge or snooze them in place. Open it with ⌘⇧A or the header’s siren mark. → Act on alerts
Debounce — the number of consecutive breaching readings a rule needs before it opens, so a single blip doesn’t page anyone. → Alert rules
Hysteresis / clear value — the level a metric must recover past before an alert resolves; it stops an alert flapping around the threshold, and defaults to the trip value. → Alert rules

NRW (non-revenue water) — treated water put into supply but never billed: leakage, metering error, and unauthorised use. → Dashboards
DMA (district metered area) — a hydraulically discrete zone of the network whose inflow is metered, so its losses can be measured against its consumption. → Dashboards
MNF (minimum night flow) — the lowest flow into a zone overnight, when legitimate use is minimal; a rising MNF is a growing leak. → Dashboards
Water balance — a zone’s metered inflow compared with the summed consumption of its meters; the gap is loss / NRW. → Dashboards
Pressure compliance — how much of the period a pressure point stayed inside its operating band. → Dashboards
