Owntracks waypoint_whitelist is ignored by HA

Dear all:

exactly how to write waypoint_whitelist?

This is what I’ve written in my configuration.yaml file and it is being completely ignored by HA:

device_tracker:
  - platform: owntracks
    max_gps_accuracy: 100
    mqtt_topic: owntracks/#
    waypoints: true
    geocode: true
    waypoint_whitelist:
      - user1
      - user2
      - user3
      - user4

where user1 user2 user3 user4 are part of my topic:

owntracks/user1/phone
owntracks/user2/phone
owntracks/user3/phone
owntracks/user4/phone

Unfortunately, this waypoint_whitelist option has no effect what so ever. Am I doing this right?

I am running my owntracks server on amazon cloud and I use mosquito as my mqtt server.

Thanks in advance

Harv
