Create an UDP server able to broadcast TeleInfo read on 'CarteElectronic' device (with 2 counters) The device is TeleInfo 2 compteurs You may have to adapt this script for other products. The script use "Standard" mode and not "Historic" mode: you'll have to ask a modification on linky, by Enedis.
The script does two important things :
- Reading each channel of the device. It's one channel at a time, so, values aren't in continuous (reading all counters took around 7 seconds)
- Broadcasting two JSON object (CPT-1 and CPT-2) on UDP port 65432
That way, any service listening on the same LAN could receive the information. Example with Wireshark:
The project use Python 3 or more to run.
It is a simple Python script, with some import, so you need to use de pip installcommand :
- pylibftdi (this part needs some drivers installed on the system:
apt install...commands) - time
- socket
- json
- logging
Simply launch the script python3 ./teleinfo_socket.py, you will see only one line informing the script is running
In case of error, you'll have to consult teleinfo.log (for example, tail -f teleinfo.log)
This part is simple and easy, but I'm going to give some troubleshooting tips.
- Install the script file in the place you want it to be run
mv ./teleinfo_socket.py <anywhere> - With root permission (sudo), create a new file
teleinfo.servicein/etc/systemd/system/with following information :
[Unit]
Description=TeleInfo broadcast (on UDP port 65432) service
After=multi-user.target
[Service]
ExecStart=/usr/bin/python3 <anywhere>/teleinfo_socket.py
Type=simple
Restart=always
PIDFile=/run/teleinfo.pid
[Install]
WantedBy=multi-user.target
- Check your file is correct for systemd :
sudo systemd-analyze verify teleinfo.service - Restart system control :
sudo systemctl daemon-reload - Enable teleinfo service (it will automaticaly run on startup) :
sudo systemctl enable teleinfo.service - Start manually teleinfo service :
sudo systemctl start
I'm reading values for my Home Automation system, here is what my Node.JS app shows me.
