RotatingMachine Example Flows

These flows are import-ready Node-RED examples for the rotatingMachine node. In Node-RED: Import > Examples > EVOLV to find them.

Example Flows

01 - Basic Manual Control

Dependencies: EVOLV only (no dashboard)

Inject-based flow demonstrating all core functionality:

• Mode switching (auto / virtualControl / fysicalControl)
• Startup/shutdown/emergency sequences
• Speed setpoint control (30%, 60%, 100%)
• Pressure simulation (upstream + downstream)
• Maintenance mode enter/leave
• Debug outputs on all 3 ports

02 - Integration with Machine Group

Dependencies: EVOLV only (no dashboard)

Parent-child relationship demo:

• machineGroupControl parent with 2x rotatingMachine children
• Auto-registration via Port 2 on deploy
• Independent pump control with group-level aggregation
• Pressure simulation on individual pumps

03 - Dashboard Visualization

Dependencies: EVOLV + @flowfuse/node-red-dashboard

Interactive FlowFuse dashboard with:

• Mode dropdown, startup/shutdown/emergency buttons
• Speed setpoint input, pressure simulation inputs
• Real-time charts: flow, power, ctrl%, NCog, state code, pressure

Legacy Files

The following files are from the original flow set and will be removed in a future release:

• basic.flow.json → replaced by 01 - Basic Manual Control.json
• integration.flow.json → replaced by 02 - Integration with Machine Group.json
• edge.flow.json → edge-case testing (inject-based)

Import

1. In Node-RED, use Import > Examples > EVOLV (auto-discovered)
2. Or manually: Import > Clipboard and paste the .json file contents
3. Deploy

Notes

• Tier 1 and 2 examples have zero dashboard dependencies — they work on any Node-RED install with EVOLV
• Tier 3 requires @flowfuse/node-red-dashboard (included in EVOLV's package.json dependencies)
• All examples use enableLog: true so you can observe behavior in the Node-RED debug panel
