From your descriptions, I have the same Kasa switch set up (with bulbs that are three stories high thanks to a walkout basement). I have them set to go off 15 min after turning on so as to 1) not waste the bulb and 2) not cause issues for neighbors. So the dog can go outside and all is good without me having to worry.
This is a 30 second solution.
Under no circumstances would I give access to my smart devices to a neighbor.
Good idea - I’ve definitely forgotten!!
