Is there a way to turn off switch when there is motion ? Or is there already an app for this?

No, I’m an all Apple household. Ha Ha.

Maybe they should have mentioned that in some kind of warning before I bought this smarthings toy.

I don’t think Android vs. Apple has much to do with it, frankly. There are quirks with the Android mobile app. But the guts of ST doesn’t depend on either, nor is there any advantage to either that I know of.
