Device tracker confusion

Configuration
1

As i’m receiveing a lot of sock errors in the logs decided to finally simplify my setup

So let’s say we have the following setup in configuration yaml for a single android phone

device_tracker:
  - platform: nmap_tracker
    home_interval: 3
    hosts:
      - 192.168.1.1
    interval_seconds: 120
    track_new_devices: yes
  - platform: ping
    interval_seconds: 120
    consider_home: 300
    hosts:
      ping_myself: 192.168.1.1
  - platform: gpslogger

This will give us 3 entries in known_hosts

#nmap entry
mymobiledevice:
  hide_if_away: false
  mac: xx:xx:xx:xx:xx:xx
  name: NMAP DEVICE
  picture:
  track: true
#ping entry
ping_myself:
  hide_if_away: false
  mac:
  name: ping device
  picture:
  track: true
  vendor:
#gpslogger entry
serial_number:
  hide_if_away: false
  mac:
  name: gpslogger_device
  picture:
  track: true
  vendor:

So now two question.

  1. Is it possible to combine all of these into one?
  2. Let’s say in nmap we first commented out the hosts: so it scanned the whole of network entering a lot of entries into known_hosts. Than we comment out the whole of nmap section… What will be the behaviour of HA considering that in known_hosts we set the directive “track: true” but as nmap is commented out there will be no means to track?

No ideas on this one?
