Another thing about IoT gadgets and "smart"stuff in general, is the guaranteed obsolescence. It's not literally planned obsolescense, but when you install that wi-fi smartlock in your door, you know that it 5 years the company will stop updating the app that goes with it, and it won't work anymore under iOS 16, and so you'll have to throw it out and get a new lock, a new dimmer, a new garage door opener, new audio system, you name it.
