<![CDATA[WeMos Teleinfo Shield with ESPHome on ESP32-S2 mini - no data being received]]>Re: Wemos Teleinfo et ESP Home

I'm trying to get the Teleinfo data working with the Teleinfo shield on an ESP32-S2 mini using ESPHome for HomeAssistant integration. I've used some of the config in the linked topic and adapted it for my hardware.

My config looks like:

esphome:
  name: bosh
  friendly_name: bosh

esp32:
  board: lolin_s2_mini
  variant: esp32s2
  framework:
    type: esp-idf

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Bosh Fallback Hotspot"
    password: "***"

Here is a picture of the board connected to the Linky:

Everything compiles and installs correctly but it seems like no data is being received from teleinfo:

I've checked that my meter is set to "Historical mode" and the baud rate is correct.

I was not sure of which way round to connect the Linky to the Teleinfo shield, but I tried both ways and neither seems to work.

Any ideas how to debug this? I'm quite new to this kind of thing? @Charles do you have any ideas?

I reconnected to the I1 and I2 pins and the LED on the shield started blinking.

However I'm still not getting data in HomeAssistant.

The logs are now showing lines like the following:

[14:43:44][E][teleinfo:038]: bad crc: got 40 except 53
[14:44:44][E][teleinfo:038]: bad crc: got 66 except 89
[14:45:44][E][teleinfo:038]: bad crc: got 35 except 46

What does this mean ?
