Those are WiFi though, no? Not exactly the same thing. Personally, I prefer a hub/bridge and then a mesh network for Home Automation. I’ve got Hue, Z-Wave, and WeMo. I much prefer the experience with the first two now.
Wifi, Bluetooth, cellular, bespoke solutions, etc. are all "just radio waves" yet entail a vast spectrum of engineering and business requirements including cost, power usage, implementation complexity, reliability, interoperability, and range.
Frequency matters for interference, also mesh versus access point makes a big difference in the real world.
