That always begs the question why everything is connected to the Internet. I think some things would be just fine on an isolated network.
“I think some things would be just fine on an isolated network.”
So do I. These wifi outlets and switches all work by logging into a central server, somewhere probably in China. You have to log in with your app and tell the server to tell your outlet to turn on or off. I do not like that arrangement. Fortunately, it is possible to reprogram many of these devices to just connect to your wifi and put up a simple web page with an on/off button that you can control with a web browser. You give up the ability to control the lights from Timbuktu, but I am fine with that.
