Export the data from the French electric meter Linky to an MQTT broker, which can then be used in HomeAssistant (or anything else you like).
I haven't done much work on this 😬 90% of the code and 100% of the electronics were designed by :
- "Decodeur TIC Linky" by MicroQuettas
- Module téléinformation TIC by faire-ca-soi-meme.fr
- Affichage déporté pour compteur Linky by ouiaremakers.com
I've just re-packaged it, thanks to all those people !
Plug into pin 12 on the ESP32.
Rename config.h.renameme to config.h and change the values according to your setup, then flash main.ino like you would normally.
Open the front green case of the meter, and plug the circuit into the I1 and I2 diagnostics ports. Be careful not to kill yourself (seriously tho be careful).
Plug-in the ESP.
this assumes you use HomeAssistant and its Mosquitto add-on as an MQTT broker
In your HomeAssistant configuration.yaml, add the following:
sensor:
- platform: mqtt
state_topic: "energy/electricity_consumption_wh"
device_class: energy
state_class: total_increasing
name: Consomation d'Electricite
unit_of_measurement: "Wh"
- platform: mqtt
state_topic: "energy/electricity_instant_intensity_a"
device_class: current
state_class: measurement
name: Courant Instantane
unit_of_measurement: "A"
- platform: mqtt
state_topic: "energy/electricity_apparent_power_va"
device_class: apparent_power
state_class: measurement
name: Puissance Apparente
unit_of_measurement: "VA"
You can then go to /config/energy/dashboard and setup the hass integration. I've personally opted to use an helper to store the electricity price as it makes it easy to update whilst maintaining continuity in the data. Here's the result :
