If we had more smart people, we'd have less need for smart IoT that actually aren't.
Smart TV's with RF remotes that work anywhere in the neighborhood? No key pad on the TV remote? WTF! You have to bring up a screen on the TV, so you can hunt and peck on the on screen keyboard to change channels. But the TV is defaulted to be programed ahead of time for what you want to watch? Works great when the football game runs long. How is this "smart"?
Smart light bulbs and plug in switches for lights, fans, heaters, etc., that need a remote server and your WiFi password and an apt to work?
You are normally right there anyway to experience the effects of whatever said device. Deal with it directly using the switch on, or near the device. Why let a server, who knows where, know about it. Especially if you are paying someone for this server to know.
I am not really a Luddite, but I prefer to control my own stuff I bought and paid for myself, without any input from any unnecessary third party.
