MMM-LKY-TIC

MagicMirror2 module to display info about home power supply (previous generation and Linky(tm) devices providing data via 'teleinfo/TIC' serial output).

For now only historical data mode, single-phased settlement, is handled.

Module is currently under development, working for use case above.

Features

Uses latest MMM-React-Canvas-ts bootstrapper:

See here for technical details

Provides quick supply status via icons

-------------
(L)  (S)  (F)
-------------

• L for Link state: a plug symbol indicates link status between counter and the module:
  • With bolt, green => data was received less than 5 seconds ago
  • With exclamation mark, yellow => data was received less than 10 seconds ago
  • With exclamation mark, orange => data was received less than 30 seconds ago
  • With exclamation mark, red, blinking => data was received more than 30 seconds ago
  • With exclamation mark, red => no data received from the start.
• S for Supply state: indicates current electrical consumption:
  • Question mark: unable to determine supply state
  • Green leaf: current intensity is less than third of subscribed intensity
  • Yellow bolt: current is less than two thirds of subscribed
  • Orange bolt: current is less than five sixths of subscribed
  • Red bolt: current is more than five sixths of subscribed
  • Red bolt, blinking: power overflow has been detected over subscribed.
• F for Fare period: displays current fare period, according to chosen fare option and time of the day.

Displays instant data

                637VA~511W
Min (d/m/y/o): 220/210/200/200VA
Max: 650/2500/3000/3554VA

• apparent power in VA, and estimate in Watt (depending on your own power factor). Power factor value can be set via the teleinfo configuration, see corresponding section below
• daily/monthly/yearly/overall statistics:
  • minimum value
  • maximum value

---

                             Intensity: 1A
                               Overuse: 3A

• current intensity in Ampere
• when apparent power exceeds subscribed value, a warning appears with the current intensity overflow in Ampere.

Displays daily, monthly, total electrical furniture and costs

Supplied (d/m/y/t): 475/1000/2500/5000wh
                        BASE: 475/1000/1500/5000wh
---------------------------------------------
Costs (d/m/y/t): ~3/8/25/35€
---------------------------------------------

Per current day/month/year and total:

• Supplied energy is detailed according to the chosen fare option (provided by Teleinfo data: BASE, HC, EJP)
• Estimated costs are computed in respect to current fare option and configured fare details (see configuration section below). Please note they don't include subscription and extra furniture costs.

Exports local data to Opensearch index

More info about Opensearch. This features requires a fully working Opensearch node + Opensearch dashboards stack (using Docker containers is supported and recommended).

When enabled (see Configuration -> Teleinfo section below), collected data is exported to the Opensearch index of your choice. Using this, you'll be able to display data in Opensearch dashboards (see above screenshot).

Examples of index mapping can be found here: data-export/opensearch/mappings.

Notes:

• For now, only per-day data is exported
• Export is processed at following events:
  • Start of current MagicMirror module
  • When MagicMirror and this module are running, and a day change is detected, so at 12 a.m.
• Make sure the Opensearch instance is accessible from you MagicMirror device, and ready to receive data; as no immediate retry is attempted on failure. The next export occurrence will be either the day after, or if you decide to restart MagicMirror
• The index might not exist already, it will be created when necessary.

Install

Prerequisites

1. Is your device able to access/read the serial port at all? Some utilities in dedicated section below may help you
2. Make sure node v18.12.1 or newer is installed

Install note

Since this module relies on serialport npm dependency which uses native modules, the @serialport/bindings-cpp electron bindings have to be added and built from module directory. The postinstall npm script should set everything up for you.

Installing this module

1. Clone repository into location of your choice (may be MagicMirror /modules/ subdirectory)
2. Run npm install inside repository folder
3. Check that MMM-LKY-TIC.js, styles.css and node_helper.js files have been created into current folder
4. (If external location chosen at step 1) Back to MagicMirror folder, create symbolic link from /modules/MMM-LKY-TIC/ subdirectory, to module repository directory: e.g ln -s ~/dev/MMM-LKY-TIC/
5. Add the module to MagicMirror config and customize it according to your needs (see below).

Configuration

Main

{
  "currencySymbol": "€",
  "debug": false,
  "teleinfo": { ... }
}

• currencySymbol: defines the symbol to be used for money (e.g cost)
• debug: enables (true) or disables (false) additional log messages for development or troubleshooting
• teleinfo: see below.

Logs

Module output can be rather verbose, especially when debug mode is enabled. To avoid running out of storage space quickly if you're controlling MagicMiror with tools such as PM2, it is highly recommended to add log file rotation mechanism!

Development

See template documentation for more details.

Utilities

teleinfo-reader

Small CLI program to diagnose reading of teleinfo data on serial input: npm run tool:teleinfo-reader.

Configuration is set via tools/scripts/teleinfo-reader/config/teleinfo-reader.json file; see 'Teleinfo section' above.

Diagnostics with picocom

It's also possible to capture raw data on serial input, using picocom command line tool: https://linux.die.net/man/8/picocom

Make sure it's installed via your distribution's packet manager, then:

sudo picocom -b 1200 -d 7 -p e -f n /dev/ttyAMA0

with (assuming teleinfo data is on historical mode):

• -b = 1200 (bauds rate)
• -d = 7 (databits)
• -p = e (even parity)
• -f = n (no flow control)
• by default, stop bit count is set to 1.

For people looking for alternatives, minicom should also work with equivalent settings.

Troubleshooting

No serial data seems to be received...

...whereas the hardware module LED is blinking!

Sometimes (might happen after a device reboot), the serial device requires reinitialization. To do this:

1. stop MagicMirror
2. use picocom tool command above
3. check raw data is correctly displayed
4. exit picocom (CTRL-A keys by default)
5. finally start MagicMirror.
