I use an Arduino sketch simulating a Youless powermeter. The Youless is a standard device in Domoticz, and report is like this:

The sketch runs on a Wemos Mini ESP8266 using just a phototransistor to monitor the time between led-pulses on the powermeter. Timing is then converted to actual Watt usage.
Let me know if you want to see the source of the sketch.

Arduino sketch for ESP8266 attached below, with some instructions on connecting the phototransistor in the sketch (in Dutch).
This sketch has been running for me for more than 6 months without problems.
As an alternative you can have a look at ESPEASY, that is able to measure pulselengths:

Thank you i will try it today.
I have already run espeasy but that can not comunicate the pulse time to domoticz
