Pulse Counter - Send a message to controller for each pulse?

[TommySharp]

I'm trying to monitor my energy usage and have a meter that has an LED that pulses 1000 times per KwH.

I had something working with an arduino where it would sent an MQTT message every time there was a pulse. Then to calculate the "live" power usage I calculated the time since the last pulse and used that to generate quite an accurate "watts" value.

Is there any way in ESP Easy to do this? Send a message each time there is a pulse?

This is how I do it.

Code: Select all

%value%*3600/<delay interval>

3600 is seconds in an hour.
