Entity missing in history

Configuration
1

I have an entity device_tracker.saradesktop and it works ok.
It is a desktop PC and I use nmap to check it:

  - platform: nmap_tracker
    consider_home: 180
    interval_seconds: 30
    hosts:
      - 192.168.188.65

but I don’t see it in the history page.
My history config file, right now, is:

  include:
    domains:
      - device_tracker

I can see all other device trackers but not that.
What I am missing?

EDIT:
My bad!
I had the entry

recorder:
  - exclude
      - device_tracker.saradesktop
