These "smart" devices are all controlled through the internet... which is insane. I don't want my home to become unusable when wi-fi is down. I want local switches that can be controlled... locally, offline. The local government here pushes "smart thermostats" which I've had fail twice because the app on the phone couldn't reach the server that day. If I must have digital controls, connect them to a physical network that's isolated from the internet, and a local panel to interact. I don't need an app on my phone. We can't use the broil feature of our oven, because it is an on-line feature only and we won't connect it to wi-fi... bastards.
