That might be a smarter way to do it! Right now I have this thing where if we don't unload the dryer it does a sort of warming cycle every 20 minutes or so. And that triggers another alert. We don't mind because that just means we _should_ unload the dryer to stop it from consuming more power.
But I suppose the countdown approach would still trigger the same thing. I suppose if I didn't really want the extra alerts I should be monitoring the duration of power consumption and exclude the ones that are of a shorter duration.
I might try the countdown approach for something different and see what results I get. Thanks for the idea!
