Yes. A hub is required for use of the Zigbee connecting devices.
This is because Zigbee communication protocol does not come standard in smart phones or routers, therefore there is no Zigbee signal for the LED's and accessories to connect with. The hub provides the connecting signal for your LED's and accessories to keep them connected and online.
The Sengled Smart Hub is compatible with all of the smart accessories from the Zigbee Smart LED and accessories line.
Additionally, the Sengled Zigbee Smart LED's and accessories are compatible with these smart home hubs:
- SmartThings Hub
- Amazon Echo devices with a built-in hub (Echo Plus, Echo Plus 2, Echo Show 2, Echo Studio)
