soldering shema for esp32 not mini

[johnx102]

Hi, I just receive my wemos tele info unit, but before order esp32 mini, I want to use my esp32 normal board . Can you explain please what pin on my esp32 I use with the WeMos ? thanks

there is no magic all depends on what you want to do, what firmware you use and wire according.

If you only want to read teleinfo you need to wire :

• GND of your ESP32 to pin labeled GND on Wemos TIC
• 3.3V of your ESP32 to pin labeled 3V3 on Wemos TIC
• GPIO23 of your ESP32 to pin labeled 13 on Wemos TIC

Hi , thanks for answer ;)
I use tasiota firmware with téléinformatiques, and yes just want read data from my linky .
So only 3 wire is enough for that ? I use esp32 board devkit (bigger than the mini show on you're topic ) https://docs.espressif.com/projects/esp-idf/en/latest/esp32/hw-reference/esp32/get-started-devkitc.html
can you confirm please if for the third is the pin GPIO23 on my device please ?

Correct, but in all case it depends on which pin is configured as TInfo Rx in tasmota, in this case it should be TInfo RX set to GPIO23 in tasmota

Please see some hints on teleinfo with Tasmota
