ESPHome total meter

Hi, I spent a lot of time playing around with my electricity meter in ESPhome over a year ago and eventually settled on the implementation detailed below which you may be able to adapt for your use case. The two things which I did which resulted in a solid and relabile solution that never seems to reset is the following:

  1. Use the total_daily_energy platform is ESPhome (I originally tried the integration platform but had problems with it spiking to an infinite value every couple of months - I was never able to solve this).

  2. Use the total_daily_energy sensor as the source for utility_meter sensors in HA (note even though the total_daily_energy sensor from ESPhome resets daily, the utility_meter keeps counting up, I don’t know why but it seems to work well).

ESP Home Config:

sensor:
  - platform: pulse_counter
    name: 'Meter Power'
    id: meter_power    
    pin: GPIO4
    unit_of_measurement: 'kW'
    accuracy_decimals: 3
    filters:
      - multiply: 0.06

  - platform: total_daily_energy
    name: "Total Daily Energy"
    accuracy_decimals: 1
    power_id: meter_power

Home Assisistant config:

utility_meter:
  energy_usage_hour:
    source: sensor.total_daily_energy
    cycle: hourly
    tariffs:
      - std
  energy_usage_day:
    source: sensor.total_daily_energy
    cycle: daily
    tariffs:
      - std
  energy_usage_month:
    source: sensor.total_daily_energy
    cycle: monthly
    tariffs:
      - std

You probably do not need my 0.06 multiply filter as these needed to convert 1000 pulses to a kWh.
