electric meter

[h143]

Hello,
i have in my home an old ferrasi electical meter and want read it out with an esp8266 and domoticz,
i have it working based on thim, but i want my instant usage calulate on time between the pulsen is there a tutorial or can someone help me?

[h143]

Is there nobody who have this worki g?

Looking for the exact same solution

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.

That is where i am looking for can you explane how you have did it. In dutch is also good for me

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
