I'm looking for a similar thing.
I'd like to see a checkbox on the schedule entries that states "triggers timer", so we can have on and off events in the schedule that don't trigger an auto on or auto off event.
As an example, my immersion heater I want to run on the schedule, but when I ask Alexa to turn on the immersion heater I'd like the auto off timer to fire after 90 minutes.
Hope that's a good use case for the separation of the timer from an individual on/off schedule event?
regards
Steve
