What is a good trigger for inactivity?

[Alex]

I would like a certain action to be triggered by inactivity, eg, if phone is idle for 60 seconds (eg, no user input), then ➜ action. What is a good trigger for this?

One way would be detecting when screen goes off:
Flow 1: Trigger display state off
Action sleep 60s-time before screen turns off

Flow 2: Trigger display state on
Action stop flow 1
