Oh, I just remembered a huge reason why I choose anything but Wi-Fi for as many smart home devices I can:
Having Internet-connected devices that don’t receive constant, timely security updates is a Bad Idea™ that’s bitten a lot of people.

And many IP connected IoT manufactures don’t commit to providing security updates.
So, the more IoT-y stuff I can keep off of IP the better. Unfortunately, this probably means I’m going to steer clear of Matter, too.
