Influxdb: write to db only every

Hi everybody,

I used to have influxdb set up like this

influxdb:
  host: !secret influxdb_host
  port: !secret influxdb_host
  database: !secret influxdb_database
  username: !secret influxdb_username
  password: !secret influxdb_password
  ssl: false
  verify_ssl: false
  max_retries: 3
  default_measurement: state

  include:
    entities: 
    # (...)
    domains:
    # (...)

  tags:
    instance: prod
    source: hass

This does exactly what it should for, let’s say binary_sensor / input_boolean entities. Their status changes, it gets logged. However, when I have something like sensor.temperature_printer (in this case, a DS18B20 on ESPHome), the state might change by the minute (or even 6 times per minute or so), which generates a lot of data.

Is there a way to limit this? I am looking for something in the likes of

# (...)
  include:
    entities:
      - entity: sensor.tempearature_printer
        interval: 2m # / 120s
        only_on_change: true

This is arbitrary yaml, but what I mean is: for entity sensor.temperature_printer log value every 2m; if value has not changed, don’t log it (otherwise do log it).

Prior to ESPHome, I had every single sensor integrated via zigbee2mqtt, so I could just let node-red take care of this; however, I don’t think it is the best solution to generate automations to send changes from the ESPHome entities to mqtt just so that node-red can work with them. There ought to be a better solution. Is there and I just missed it?

Thank you for your ideas
