100% you don’t want WiFi smart home devices.

WiFi is really handy because it’s easy and accessible, but as you add devices, you wind up with WiFi network issues.
Because these devices can just talk to the internet, they can talk to their manufacturer’s websites and tell them everything they learn about you from your network, such as all the other devices on your network, any open file sharing protocols (and the files on those devices), any other devices that are willing to talk to the WiFi device. So - literally - everything on your network becomes exposed to the manufacturer of the device. It’s unlikely the manufacturer would be nefarious, but they would extract all your data.
And if the device has poor security, opens a port to the outside world, or - as I discovered this weekend on my soundbar - just has a root ssh shell with no password requirement, it could pose a security risk to you and your devices.

…. And I just remembered outbound federation is currently broken on my instance and maybe one person will actually see this comment. Fuck.
