Counters

Count the power consumption of the inverter in three instances:

• Battery power Increment\Decrement values -+ kWh
  • Can caltulate estimated kWh usage from batteries, how many left, how charged.
• Invertor power Increment\Decrement values -+ kWh
  • Can show power losses during charge cycles, just for info.
• Mains Invertor power Usage - simple kWh per time with 0 values during blackouts.
  • Can show the full power usage by the invertor from the Main grid

Meters

NOTE: Utility meter uses sensor by its name in snake_case, cannot use unique_id, dont know why.

Consists of different meters each:

• Check the battery kWh charged and discharged
  • NET - can be positive\negative
  • reset by automation at battery SoC 100%
• Invertor power usage net, to see power losses
  • NET - can be positive\negative
  • reset by cycle
• Invertor full power usage from main grid
  • can be zero on blackouts
  • montly
  • weekly
  • full

Seems OK:

• https://community.home-assistant.io/t/home-battery-on-energy-dashboard/463059/6

Preprequisits:

1. Make a template sensor to filter out negative float numbers and other cleaning (below)
   1. Based on actual invertor sensor fro, ESP32 module: sensor.easun_easun_battery_average_power
2. Make Invertor counter for Wattage in or out of batteries: see
   1. Based on the step 1. from current module: sensor.easun_battery_in and sensor.easun_battery_out
3. Add in the battery section at energy page

Invertor reports a battery charge\discharge as a counter with pos\negative values. Convert negative value to ABS positive and report as a separate discharge sensor. Report charge sensor for convinience by sorting out any negative float by reporting zero instead.
