Teleinfo-js

Node module to read teleinformation frames from ErDF / Enedis main circuit breaker (in France).

Wrapped on serialport module to read from a serial / USB port. Tested on RaspberryPi.

Based on Laurent HUET work.

Prerequisites

• A RaspberryPi or equivalent computer to plug adapter and run the module.
• An adapter (see tested hardware below) to plug between main circuit breaker TIC interface and your computer.
• This adapter should be able to connect to serialport module: sending serial data or emulate it from USB port.
• A classical white ErDF circuit breaker, or a Linky.
• For Linky, TIC must be set to Historique mode.

Tested hardware

• RaspberryPi 2 with Raspbian.
• GCE Electronics USB.
• Tested on Linky (TIC History mode), use I1 and I2 outputs (no polarity).

Start with a simple example to try it.

mkdir teleinfo-test && cd teleinfo-test
npm install teleinfo-js
 
ls /dev/tty*
# this will scan serial ports. Plug/unplug your adapter to look after a change. 
# Then for example 'ttyUSB0', type: 
cd node_modules/teleinfo-js && npm run start -- /dev/ttyUSB0

You should receive more than 1 frame per minute. If so, you can start to write your own implementation.

First step to begin

const teleinfo = require('teleinfo')
// use your own port here:
const emitter = teleinfo('/dev/ttyUSB0')
 
emitter.on('rawFrame', function (data) {
  console.log('rawFrame', data)
  // You will receive ALL raw data.
})
 
emitter.on('error', function (error) {
  console.error(error)
  // In case of error from serialport module.
})

For better events and parsed data

emitter.on('connected', function (data) {
  console.log('connected', data)
  // When connection succeed and first data is received.
})
emitter.on('failure', function (data) {
  console.log('failure', data)
  // When connection cannot be established.
})
emitter.on('frame', function (data) {
  console.log('frame', data)
  // You will receive all parsed frames.
})
emitter.on('change', function (data) {
  console.log('change', data.changes)
  // You will receive only changes.
})
 
emitter.on('diff', function (data) {
  console.log('diff', data.diff)
  // You will receive a full structured diff object for convenience.
})

For less events

You can add inhibitors to your teleinfo instance. These will avoid too many change/diff events to be triggered. For example, to trigger events when PAPP value delta is above 30W, or HCHP/HCHC index delta are above 5Wh:

const emitter = teleinfo('/dev/ttyUSB0', { 'PAPP': 30, 'HCHP': 5, 'HCHC': 5 })

By default, inhibitors = { 'PAPP': 20 }.
