Impulse readers / electricity metering

Configuration
3

I just finished that project today :slight_smile:
I think it needs some additional fine tuning with conversion, etc.
If anyone has any suggestions how to make this configuration better, please share :slight_smile:

I copied this project from this guide: Here (polish)

Here is what I did:

Assumptions:

  • MQTT Broker configured
  • ESP Flashing Basics Guide

Hardware:

  • ESP-12E CP2102 NodeMcu Lua V2 Here
  • Photodiode Here
  • Connector Wires
  • Duct tape :wink:

Steps:

  • Connect photodiode to GPIO Pin (my case GPIO-14), Voltage (3.3V) and GND

  • Flash ESP Easy Mega Here

  • Configure ESP to communictae with MQTT Broket in HA

  • Configure device in ESP:

    Note: Values 1/6400 is defined by my electricity couter from provider - it is stated on cover as 6400 impulses / kWh
    Note2: Change “Count” value to: “(%value%*(1/6400)) * 1000 * 60” to get value of Watts every 60 seconds

  • Configure MQTT sensors in HA:

    First one uses Count value and provides power consumption every minute (ESP is set to 60 seconds interval - screen above)
    Second one uses Total value and provides input for utility meter component:

  • Place photodiode directed on electricity meter flashing diode:

    Duct tape is your friend :slight_smile:

Final efect looks like this:

I added cost calculation
