oh I’m sorry. I think i confused this with a plug topic I just spoke to someone about. my apologies.
as for the case you laid out, using a wall switch, turning it ( the wall switch) off for a second and then back on will turn the light on. the only slight issue I would see he is that unless you use the app to turn it back off you would have to use the physical switch again and that would remove the ability to control it from the app as it would have no power to it.
sorry again for the confusion on my part.
