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'
- analog2 => 'Analog v2 device'
- breath => 'Breath device'
- comfort => 'Comfort device'
- comfort2 => 'Comfort 2 device'
- comfortSerenity => 'Comfort Serenity device'
- drycontacts => 'Dry Contacts device'
- drycontacts2 => 'Dry Contacts 2 device'
- deltap => 'Delta P device'
- modbus => 'Modbus 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
