When I started at Ars in the summer of 2022, the next generation of smart home standards was on the way. Matter, an interoperable device setup and management system, and Thread, a radio network that would provide secure, far-reaching connectivity optimized for tiny batteries. Together, they would offer a home that, while well-connected, could also work entirely inside a home network and switch between controlling ecosystems with ease. I knew this tech wouldn't show up immediately, but I thought it was a good time to start looking to the future, to leave behind the old standards and coalesce into something new.
Instead, Matter and Thread are a big mess, and I am now writing to tell you that I was wrong, or at least ignorant, to have ignored the good things that already existed: Zigbee and Z-Wave. I've put in my time with Wi-Fi, Bluetooth, and various brittle combinations of the two. They're useful for data-rich devices and for things that can stay plugged in. Zigbee and Z-Wave have been around, but they always seemed fidgety, obscure, and vaguely European at a glance. But here, in the year 2024, I am now an admirer of both, and I think they still have a place in our homes.
The internet and cloud points are my favorite. Specifically the fact that those things are out of the picture.
No VLAN configuration necessary. The hub is "the VLAN". They literally can't phone home because they have no route to the internet, with no extra setup necessary. For WiFi devices, I have to make sure they're connecting to the right VLAN and controlled properly, and if I misconfigure something, they are phoning home or joining a botnet.
(This stops being as applicable if you have a sketchy hub you don't trust, but I trust deconz and ZHA fine enough in this context).
