node-red-contrib-adeunis-codecs

A Node-RED node that uses adeunis-codecs library to decode hexadecimal payloads generated by adeunis devices

Install

Either use the Manage Palette option in the Node-RED Editor menu, or run the following command in your Node-RED user directory - typically ~/.node-red

npm i @adeunis/node-red-contrib-adeunis-codecs

Usage

A simple node that decodes payload from adeunis devices into a human-readable JSON output

Node input content:

• productType:
  • analog => 'Analog device'
  • breath => 'Breath device'
  • comfort => 'Comfort device'
  • comfort2 => 'Comfort 2 device'
  • drycontacts => 'Dry Contacts device'
  • drycontacts2 => 'Dry Contacts 2 device'
  • deltap => 'Delta P device'
  • motion => 'Motion device'
  • pulse => 'Pulse device'
  • pulse3 => 'Pulse 3 device'
  • pulse4 => 'Pulse 4 device'
  • pulse4nbiot => 'Pulse 4 NB-IoT device'
  • repeater => 'Repeater device'
  • temp => 'Temp device'
  • temp3 => 'Temp 3 device'
  • temp4 => 'Temp 4 device'
  • ticCbeLinkyMono => 'TIC CBE/LINKY MONO device'
  • ticCbeLinkyTri => 'TIC CBE/LINKY TRI device'
  • ticPmePmi => 'TIC PME-PMI device'
• payload : hexadecimal string

Typical content that could be written in a node function:

msg.productType="analog";
msg.payload = "42500110000002100000";
return msg;

Node output content:

• productType : product type
• raw : initial payload
• msg.payload : decoded payload

Output example:

{
  "_msgid": "2d511469.028d8c",
  "topic": "",
  "payload": {
    "type": "0x42 Analog data",
    "status": {
      "frameCounter": 2,
      "hardwareError": false,
      "lowBattery": false,
      "configurationDone": false,
      "alarmChannelA": false,
      "alarmChannelB": true
    },
    "channels": [{
      "name": "channel A",
      "unit": "V",
      "value": 1.049
    }, {
      "name": "channel B",
      "unit": "mA",
      "value": 10.486
    }]
  },
  "productType": "analog",
  "raw": "42500110000002100000"
}
