Automation with timestamp condition

Configuration
1

I am trying to build an automation where within a certain timeframe, I want the bathroom fan turned on with the bathroom light turning on and depending on how long the bathroom light stays on, I want two paths:

  • Path1: more than 10 seconds, turn the fan off 15 minutes after the light goes off.
  • Path2: (default): less than 10 seconds, turn the fan off when the light goes off.

I’ve tried building this automation using the GUI editor but I’m not getting desired behavior as automation always goes the default route, turning fan off immediately after light is off, regardless of the time the light was on. As shown in the screenshot below, time on was >10s but still went default route.

The value_template: "{{as_timestamp(now()) | int - as_timestamp(states.light.baie_light.last_changed) | int}} reports true when tested under developer tools so it doesn’t make sense to me. Is this a limitation of the visual editor?

My automation has an additional option which works fine but concerning failing option starts at line 32:

The issue is that by the time you are checking the conditions the state has already changed to “off”. And that means that the “last_changed” is always going to be to the “off” state and will always be less than 10 seconds so those actions will never happen.

the only way I can think to do it would be to capture the date/time that the switch went to “on” in an input_datetime and then use the current time difference to that input_datetime to determine your choose actions.

Based on your initial requirements could you not do something like the following:

Turn fan on
Wait for trigger of light turning off with a wait of 10 secs but continue on time out
Then have a choose with option 1 being state of light off = turn off fan And option 2 being state of light on with a wait for trigger of light turning off and then delay 15 mins then turn off fan.

Sorry for garbled message, I would type out an example but on iPhone.

That does the job nicely! Thank you!
