node-red-contrib-rpo-sequencer

Multi-channel sequencer for boiler/chiller staging with wear leveling. Distributes load across 2–8 channels and activates/deactivates them based on demand percentage, respecting minimum on/off times.

Install

npm install node-red-contrib-rpo-sequencer

Usage

Send demand percentage (0–100%) as msg.payload.

| msg | Effect | |-----|--------| | msg.payload = 60 | 60% demand — activates proportional number of channels | | msg.payload = true/false | Boolean: 100% or 0% demand | | msg.forceChannel = [true, false, true] | Force specific channel states | | msg.reset = true | Reset all channels and runtime counters |

Output

msg.payload = array of boolean channel states, e.g. [true, false].

{
  "sequencer": {
    "demand": 60,
    "activeChannels": 1,
    "channels": [true, false],
    "runtimes": [12.5, 8.2],
    "wearLevel": true
  }
}

With wear leveling enabled, the channel with the least runtime is activated first.
