Total Daily Energy Sensor

The total_daily_energy sensor is a helper sensor that can use the energy value of other sensors like the HLW8012, CSE7766, ATM90E32, etc and integrate it over time.

So this component allows you to convert readings in W or kW to readings of the total daily energy usage in Wh or kWh.

# Example configuration entry
sensor:
  - platform: total_daily_energy
    name: "Total Daily Energy"
    power_id: my_power

  # The power sensor to convert, can be any power sensor
  - platform: hlw8012
    # ...
    power:
      id: my_power

# Enable time component to reset energy at midnight
time:
  - platform: sntp
    id: my_time

Configuration variables:

  • power_id (Required, ID): The ID of the power sensor to integrate over time.

  • name (Required, string): The name of the sensor.

  • id (Optional, ID): Manually specify the ID used for code generation.

  • restore (Optional, boolean): Whether to store the intermediate result on the device so that the value can be restored upon power cycle or reboot. Defaults to true.

  • min_save_interval (Optional, Time): The minimum time span between saving updated values to storage. This is to keep wearout of memory low. Defaults to 0s.

  • method (Optional, string): The method to use for calculating the total daily energy. One of trapezoid, left or right. Defaults to right.

  • All other options from Sensor.

Converting from W to kW

Some sensors such as the HLW8012 expose their power sensor with a unit of measurement of W. To have your readings in kW, use a filter:

sensor:
  # The power sensor to convert, can be any power sensor
  - platform: hlw8012
    # ...
    power:
      id: my_power
      filters:
        # Multiplication factor from W to kW is 0.001
        - multiply: 0.001
      unit_of_measurement: kW
