Influxdb question in the HA configuration - how to exclude/include data

I think that I have a simple question, but I can’t quite figure it out myself.

I use Influxdb2 in the Home assistant configuration so that I can collect data from different sensors.
However, that data accumulates very quickly, so I have to make a choice as to which data can be collected and what not.

I have added my Samsung TV as sensor in the configuration file like this

  api_version: 2
  ssl: false
  host: x.x.x
  port: 8086
  token: x.x.x
  organization: x.x.x
  bucket: home_assistant
  max_retries: 3
    - friendly_name
      - media_player.samsung_7_series_43

In Influx I see a lot of data there:

But Iam only interested in the State of the device…

Can I somehow ONLY include the _field “state” for this particular sensor?
Any ideas?

so to summarize I’m only interested in the state and time (ofcourse), so:

thanks in advance!
