pumpingStation - Example Flows

Node-RED flows demonstrating the Phase-2 pumpingStation node on the canonical topic API (set.mode, set.inflow, set.outflow, set.demand, cmd.calibrate.volume, cmd.calibrate.level). Legacy aliases (changemode, q_in, q_out, Qd, calibratePredictedVolume, calibratePredictedLevel, registerChild) still work but log a one-time deprecation warning; these fresh flows use the canonical names only.

Files

File	Tier	Tabs	Purpose
`01-Basic.json`	1	Process Plant	Single pumpingStation driven by inject nodes - no parent, no dashboard.
`02-Dashboard.json`	2	Process Plant + Dashboard UI	Same command surface as Basic, but driven by FlowFuse Dashboard 2.0 widgets — `ui-button` controls + `ui-text` live status panel.

Prerequisites

Node-RED with the EVOLV package installed (so the pumpingStation, measurement, machineGroupControl, and rotatingMachine node types are registered).
For 02-Dashboard.json: @flowfuse/node-red-dashboard (Dashboard 2.0).

How to load

# Drop a file into a running Node-RED instance using its Admin API.
curl -X POST -H 'Content-Type: application/json' \
  --data @nodes/pumpingStation/examples/01-Basic.json \
  http://localhost:1880/flows

Or in the editor: Menu -> Import -> select file -> Import. The flows import into their own tabs and can be deployed immediately.

01-Basic - what to try

Deploy.
Inject set.mode = manual.
Inject set.inflow = 60 m3/h - the basin starts filling. Watch the formatted Port 0 payload in the debug sidebar.
Inject set.demand = 40 % - in manual mode this would feed any registered children; here there are no pump children so it is logged and shown on Port 0.
Inject cmd.calibrate.volume = 25 m3 to jump the predicted-volume integrator to half-full.

02-Dashboard - what to try

Deploy.
Open the dashboard at http://localhost:1880/dashboard/pumpingstation-basic.
Click Mode: Manual or Mode: Levelbased in the Controls panel.
Click Inflow 60 m³/h to push wastewater into the basin — the Status panel on the right shows level / volume / volume % rising.
In manual mode, click Demand 40 m³/h — the value surfaces as Manual demand in the Status panel and in the node's status badge.
Use Calibrate V = 25 m³ or Calibrate L = 1.5 m to snap the predicted-volume integrator.

All buttons fire the same canonical msg.topic as the Basic flow's inject nodes; the only difference is the trigger. The Live status panel is fed by Port 0 via a small fan-out function that caches last-known values so delta-only updates never blank a row.

Layout conventions

These flows follow the EVOLV layout rule set in .claude/rules/node-red-flow-layout.md:

Tabs split by concern: Process Plant (EVOLV nodes) / Dashboard UI (ui-* widgets) / Setup (once-true injects).
Cross-tab wiring via named link out / link in channels: setup:to-ps-mode, setup:to-ps-inflow, setup:to-mgc-mode, cmd:ps-mode, cmd:ps-demand, evt:flow, evt:level, evt:volpct, evt:state, evt:perc, evt:dir, evt:tempty.
Lane positions L0-L7 = [120, 360, 600, 840, 1080, 1320, 1560, 1800], driven by each node's S88 level (Process Cell on L5, Unit on L4, Equipment on L3, Control Module on L2).
Group boxes wrap each parent + its direct children, coloured by the parent's S88 level.

Regenerating

The current example JSON files are hand-maintained. If you re-introduce a generator, regenerate 01-Basic.json and 02-Dashboard.json from it rather than editing the JSON directly.
