The problem is that lots of little wifi devices on your network will slow down everything where latency and throughput is relevant. I guess WiFi 6 will "fix" this, so maybe I'll be wrong when light switches are all WiFi 6, but I'm right for now. Also, latency is very relevant for IoT stuff. Lights turning off 2 seconds after you push a button is a crappy experience.
