This repository contains python software dedicated to Raspberry Pi for Linky TIC decoding.
For this, I used an LCD display shield for Raspberry Pi. My selection was a Nokia-based monochrome shield like the one described here: https://www.tomshardware.com/news/nokia-cell-phone-screen-finds-second-life-as-raspberry-pi-shield but other similar shields would do as well. The current python code is using Pillow as a graphical display library, and the Adafruit_Nokia_LCD library to drive the LCD display via an SPI link.
Also I home-made a Linky serial adapter including optocoupler and transitor-based level shifter. Examples can be found here: https://faire-ca-soi-meme.fr/domotique/2016/09/12/module-teleinformation-tic/
Once the serial adapter is plugged into the Raspberry Pi, a new serial device will be accessible from Linux (like /dev/ttyUSB0), this is how we will get the TIC information from the Linky meter.
We will then use the LCD to display the withdrawn power in real-time, together with a history of the last few minutes of measurements. To get more exhaustive data, I asked my electricity provider to have my Linky meter switched to TIC standard mode instead of TIC historique, this mode is expected by the python code, as it opens the serial port in 9600 bauds mode.
