ASUSWRT Automation trigger

Hoping someone can help and this is the right section for this question

I have just set up ASUSWRT integration and all devices are now shown and toggle correctly as “Home” or Away.

However I am trying to set a simple automation trigger based on a device coming home but I am unable to get it to trigger so have clearly missed something, interestingly even if I change the device tracker state via developer tools the automation still does not trigger, i have tried the following:

Think this is correct trigger to use:

    trigger:
      - platform: state
        entity_id: device_tracker.asus_picoiphone
        to: home

I have tried setting the from option also using “away” and or “Away”

What really stupid thing am I missing here?

Thanks in advance
