Why Bluetooth?

"Bluetooth has become one of the best methods for connecting smart devices. Internet of Things standards like Zigbee and Z-Wave still have plenty of issues, and WiFi, while popular, draws too much power to be effective for managing several smart devices. Meanwhile, most devices support Bluetooth by this point, and it can also maintain connections without using too much battery life."
