Hello, I checked everything again. However, I have now noticed in the LOG that ESPeasy has a memory overflow if there is too much data. That's why everything always hangs up.

Hello, yes I tried everything. RX and TX swapped times. The meter sends (checked with camera and pin entered on meter). Nothing is displayed in the ESPeasy's LOG.

Hello, I did. Unfortunately no change. There is also no data record from the read head in the ESPeasy log. And the connection does not turn green with the ioBroker adapter either. Do you have to adjust something in ESPeasy? Except for the settings you described above?

hello, i have set everything as you wrote. EsSPeasy says "connected", but the Smart Meter adapter shows "not connected". I don't see any status in the ESPeasy log at ser2net either.

What information is present on the red marked points? It looks like a IR LED + photo transistor. I would expect the blue marked point to be easier as it is just flashing once per N Wh. (I assume 1000 imp/kWh, so 1 flash per Wh) in the appendix you can see what the red marked interface delivers. And...

Hallo, ich hätte Interesse. Suche gerade eine Lösung um meinen Zähler mit ESPeasy auszulesen.
Würde gerne über die Rot markierte Schnittstelle alle Daten auslesen und per MQTT weiter reichen.

Ok, I'll try that once in a while. But will there be an official plugin selection in ESP Mega in stable? What is not working on the last two options (http)?

I meant the bus with I2C. That's why I always thought I could search the display on the I2C. But it all seems to be more difficult than expected. Especially if you have no idea how to program an ESP8266 yourself and write programs.

Hi guys, I'm new here in this forum and from Germany. Sorry for my bad English. Can I explain one step by step how to set ESPeasy to recognize the display via I2C?
Unfortunately, this does not work for me. Have the current Espeasy Mega flashed in the trial.
