Bluetooth/Bluetooth LE 
Bluetooth is a wireless radio frequency technology that devices use to connect and/or communicate 
with other devices over short distances. 
Bluetooth LE is the new-and-improved Bluetooth. It’s popular in smart devices due to its low 
energy consumption allowing devices to run for years on a single battery. 
Geofencing 
Geofencing is a feature used to trigger a function as soon as you (and your phone/tablet) enter or 
leave an area – like your smart lights turning on as you walk to your front door. 
This is done by using the GPS, Wi-Fi or Bluetooth in your smartphone/tablet to create a virtual 
boundary around a real-world location. 
Hub 
A central device that lets you control all your smart devices through one interface, and enables them 
to speak to each other and perform sequential, coordinated functions – like having the kettle boil 
after the kitchen lights turn on. 
Most smart devices come with their own app to control them, so you don’t need a hub. But having 
one is useful if you’d like everything hooked up to one “master control”, and want to avoid 
switching apps all the time. Learn more about smart home hubs.
