When I want an automation to trigger when an entity’s state remains constant for, say, 10 seconds, I’d like to be able to write this:
automation:
trigger:
platform: state
entity_id: device_tracker.donka_phone
for: "00:00:10"
#...
In my mind, this should trigger when the device is set to “Away” or “Home” (or anything else) for 10 seconds.
Currently, however, Home Assistant throws an error if you try to specify a for: duration without a “From” or a “To”.
You can add multiple triggers with every From/To permutation, but it’s annoying. Particularly if you ever need to change the duration to something else.
