Home Assistant Recorder configuration¶

Power meters and energy sensors are updated every secondes. By default, Home Assistant recorder is saving these informations in its database.
To optimize data storage in Home Assistant, it's essential to configure databases appropriately.

First Identify the Target Sensor to filter out
Power meter provides a sensor named real_power.
Energy counter provides a sensor named theorical_energy_diverted.
In your Home Assistant it should be prefixed with the name of your device and should then be identified with an id like sensor.solarrouter_real_power or sensor.solarrouter_theorical_energy_diverted.
Check your sensors to adapt the configuration.
Then Create a recorder configuration for Home Assistant
Add the following lines in your configuration.yaml to filter out real_power and theorical_energy_diverted data:
```
recorder:
  exclude:
    entities:
      - sensor.solarrouter_real_power
      - sensor.solarrouter_theorical_energy_diverted
```

About recorder

Home Assistant recorder is constantly saves data in database. Refer to recorder configuration for details.
It is strongly advised to have a look to data produced by your solar router and adapt your configuration according to your needs.

If you are using InfluxDB

If you are using InfluxDB, you should pay the same attention about data recording.
Refer to the integration documentation to exclude real_power and theorical_energy_diverted from your database.
