PC-Cop-HomeAssistant

Main goal of that project is to create sensors for home heatpump. Project contains:

• board schematics with:
  • ESP32Dev Kit
  • ILI9341
  • PZEM004-T
  • 2x Dallas DS18b20
• ESPHome yaml file

That project by using sensors gives data about Your heatpump:

• Temperatures
  • supply and return
• Electrical characteristcs
  • power (when heating or cooling)
  • current
  • consumed energy
  • voltage
  • power factor
• Calculates
  • COP - coefficient of performance
    • heating
    • cooling
    • daily
  • heating or cooling power
  • produced heating or cooling energy

Current limitations:

• I assume that water flow through heatpump is 20 litres per second
• pump in your heating system must have constant performance
• project assumes that heatpump is generating power only if electric power is greater than 100Watts
• assumes water density at 994

How to change constants:

in lines: 113,128 there is an equation beginning with 0.02, that means 20 litres/sec
