By far my best experience with any sort of smart home device was for my apartment in Boston. My overhead light did not have a switch, and the previous homeowner used a pull cord. I replaced it with a Phillips smart LED that connected wirelessly to a physical switch that I pasted onto the wall. No electrician, and now my light has a switch. $30 well spent. I never did get around to connecting it to an app or anything like that. Oh, I also had a WiFi enabled outlet! That was a gift from my sister in law. I used it on an air conditioner -- if I remembered, I could turn on the AC an hour before I got home. I also have a WiFi enabled AC in my new home and can set each room's temperature individually by app. These things are useful and convenient but I'm not really going out of my way to set them up.
