Reduce amount of sensor data

Depending on the configured pulse rate, the type of house/apartment and the heating system in use, the sensors that are exposed to Home Assistant may produce a lot of data. For example, with the default pulse rate of 1000, a power consumption of 3600 W means that the sensors produce 2 HA state changes per second (which means 7200 state changes per hour).

If you don't need that kind of granularity, you can use ESPHome sensor filters to reduce the rate of updates written to Home Assistant. This can be done by adding the following YAML code at the bottom of your Home Assistant Glow configuration file:

your_glow_config.yaml
sensor:
  - id: !extend sensor_energy_pulse_meter
    filters:
      # Update the sensor with an average every 10th second. See
      - throttle_average: 10s
      - filter_out: NaN
    total:
      filters:
        # Update the sensor once per 0.1 kWh consumed, or every 5th minute, whichever happens sooner.
        - delta: 0.01
        - heartbeat: 300s

After applying the filters, only 396 state changes will be produced per hour. You can read more about making YAML adjustments on the customizing the firmware page.
