Asuswrt seems slow to mark device as 'away'

I have finally got Home Assistant set up with a pretty simple configuration. I am just controlling 2 switches and turning them on/off based on if device(s) are home. I am using Asuswrt for device tracking and it seems to be very fast to recognize when a device connects and marks it home within seconds. But marking a device as not_home seems to take around 3 minutes+. I have tried a config section for device_tracking using asuswrt as the platform so I could use interval_seconds and consider_home but the settings don’t seem to have any effect. Here is the section of YAML:

  username: *****
  password: ****

  - platform: asuswrt
    interval_seconds: 10
    consider_home: 60

Is there any way to speed up detection of devices when they drop off the network? Most people seem to have pretty good results using Asuswrt from what I have read.
