Operation
The Hue Bridge is the central controller of the lighting system which allows the bulbs to "communicate" with Apple HomeKit and the app. In 2016, Philips released a new square shaped v2 bridge with increased memory and processor speed which replaced the round v1 bridge. The first-generation bridge received a final software update in April 2020 and disabled support from the Philips web servers. Functionality like grouping lights into rooms and scheduling scenes that depended on Philips servers to pack the instructions into a form the bridge executed could no longer be created. Early adopters were forced to buy a V2 bridge in order to use their light bulbs other than as configured before the server cutoff, a limitation not typically amenable to the technologically adventurous tinkerers who best typify the early adopters of new home automation products.
The Hue system was released in October 2012 as an Apple Store exclusive and was marketed as the first iOS controlled lighting appliance. Products released prior to 2019 use the Zigbee Light Link protocol, a compatible subset of Zigbee 3.0, to communicate, while lighting products released after 2019 use either Bluetooth, or Zigbee 3.0. Smart switches, motion detectors, and other accessory devices e.g. Hue HDMI sync, used the Zigbee Home Automation protocol but now also use Zigbee 3.0. Hue system components can be controlled via any internet device, but most typically  smartphone apps over cellular or WiFi networks, or a Home automation voice command interface. Commands are delivered to the bridge via a wired Ethernet connection which transmits the commands to the devices over the Zigbee mesh network. The initial system had bulbs capable of producing up to 600 lumens while the newer systems have bulbs that produce up to 1600 lumens.
