I can understand your indignation when people berate the "Wi-Fi" devices. It is, in part, for lack of understanding that not all Wi-Fi devices require cloud. Generally when people think of Wi-Fi, they automatically link the device to a cloud server somewhere in the world. Our engineers have tested plenty of local network devices that communicate with the router via Wi-Fi, then connect to the hub via local network (Lifx, Hue, and more, just to name a few).
I am sorry you feel that the title of the list of devices that our engineers confirmed to have worked as expected, is injust. We greatly appreciate the efforts that our community is making to enhance users' experience, and we so highlight that fact, by stating that the list of "Compatible Devices" is not all inclusive. The last paragraph even says:
"While this list includes devices known by Hubitat to work, there are countless other devices users have been running on their hubs. Visit our Community Devices Page to see other devices users have running on their hubs. Some of these devices use custom drivers, for which support comes from the custom driver author, not from Hubitat."
