What is a “hub” and do I need one?
A “hub” is a central device or mobile app that connects different smart home devices. Hubs can communicate to connected devices using WiFi, Zigbee, Z-Wave, and/or Bluetooth.
If there will only be a few WiFi devices being controlled in the home, a hub may not be required, although it is still recommended. If a large number of connected devices are to be controlled in a smart home, a hub is a necessity.
