alt Hacker NewsWhat I don’t like about Zigbee though is that it is on the Wifi band so every device with wifi antenna can snoop on it. Even assuming the protocol is secure, anyone can infer patterns and devices based on traffic shape. For example, a motion sensor that sends data whenever someone walks by. In the end, nothing beats physical wires in terms of privacy and reliability if I understand correctly.

Deployed wiring is indeed best. I will say wireless devices are often deployed while their wired counterparts sit there on the to-do list.

The other fun thing about them is because they talk Wi-Fi frequencies, if you break into them they can also be reprogrammed to act like a hotspot, or start commanding _other_ devices.
So if you send a drone up the side of an office building to the executives floor, and can break into one lightbulb wirelessly, you can then make that lightbulb break into all the other lightbulbs, until you reach the secluded inner rooms, and you can make that lightbulb listen for Wi-Fi traffic and can pretend to be a hotspot for the targetted executive's laptop. Like in the movies!
