KWH meter S0 config not working

ESPHome
1

Hi guys,

Let me start with that I’m not a coder. So I use tutorials and hope it works the first time :slight_smile:

I have the following set up:
-esphome with the S0tool code from huizebruin.
-Esp32 connected to a KWH meter LEM022SJ. 400 pulses per kWh (2.5Wh/imp)
-KWH meter to read usage of Tesla wallcharger.

The S0tool is reading KW and KWH. But there is actually nu power been drawn. So it reads false pulses I guess. Imgur: The magic of the Internet

What am I doing wrong?

The code is as following:

select:

:arrow_down: imp/kWh rate :arrow_down:

  • platform: template
    name: “Pulse_rate kWh meter”
    id: Select_pulse_rate
    optimistic: true
    options:
    • “2000”
    • “1500”
    • “1000”
    • “500”
    • “400”
    • “100”
      initial_option: “400”
      on_value:
      then:
      • logger.log:
        format: "Chosen option: %s "
        args: [“x.c_str()”]

Hello Delusional112.

i wrote the code for the esp8266 and specially for the wemos d1 mini.

therefore u cannot put it on a esp32 without modify the code.
