What is the difference between Zigbee and Wi-Fi smart-home sensors?

Zigbee sensors use a low-power mesh that needs a hub or USB coordinator but sips battery and keeps data local; Wi-Fi sensors connect straight to your router but use more power and often depend on a cloud app.

What is a mmWave presence sensor?

A mmWave radar sensor detects tiny movements such as breathing, so it can tell a room is occupied even when someone sits perfectly still — something ordinary PIR motion sensors cannot do.
