From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

IOT devices shouldn't connect to wifi. ZWave or zigbee is much better suited to IOT stuff, but it seems to mostly get adopted in very limited, locked down proprietary shit like Hue Lights.
Isn't Matter supposed to solve this issue?
There's only one case I've found where Wi-Fi use seems acceptable in IoT: ESPHome. It's open-source firmware for microcontrollers that makes DIY IoT sensors and controls accessible over LAN without phoning home to whatever remote server, without trying to make anything accessible over the Internet, and without breaking in any way if the device has no route to the Internet.
I still wouldn't call Wi-Fi use ideal even there; mesh can help in larger homes and Z-Wave/Zigbee radios tend to be more power efficient, though ESP32 isn't exactly suited for a battery-powered device that's expected to run 24/7 regardless.
Yes but at least Hue (and IKEA and LIDL and many other brands') lights work well with open Zigbee coordinators, like deconz and ZHA in Home Assistant.
I wish there were more Zigbee and Zwave and less WiFi IoT devices too. I don't even have a Zwave coordinator because I never found anything I wanted with Zwave support.
