Yeah as I’ve researched smart home stuff I’ve become more and more impressed with HomeKit. The HomeKit devices talk to iOS devices over the LAN and then an Apple TV acts as the “bridge” that lets you control your house over the internet. It sucks you have to buy an Apple TV to do it but I’m more comfortable having my thermostats, light switches, etc. all connect to the internet through a single (and reliably updated) device vs. relying on individual manufactures to secure their devices.
