I had a need to set a timer with the "once" setting. I had assumed that the timer settings would disappear after they ran. Nope. They’re still in the list. However, I don’t see any way to tell if the timer is "armed" to run, or has already run.
For instance, I set an on/off sequence for Monday. On Wednesday, I see the timers, but can't tell if the sequence ran two days ago, or is armed for next Monday.
Am I missing something?
