Iphondetect configuration

[open mirage]

I've configured Iphonedetect succesfully. My consider_home parameter seems to not have any effect.
config:

  - platform: iphonedetect
    consider_home: 2000
    scan_interval: 60
    new_device_defaults:
      track_new_devices: true
    hosts:
      michel: 192.168.178.32 
      teresa: 192.168.178.187
      till: 192.168.178.31
      eliah: 192.168.178.136

The Iphones of my roommates are going to sleep for under 2000 seconds. To my understanding of consider_home they should have been not flagged away.
