Mesh Gateway Hub is required to be synchronised with mesh related lighting products i.e. Yeelight Downlight, Spotlight & B39/A60 light bulb.
This is how the Mesh Gateway Hub works: Each Mesh Gateway Hub has Wi-Fi / Bluetooth range of up to 10m, without any wall as obstruction.
The connection works in this manner: The Spotlight is connected (best to pair on phone Yeelight APP by standing below the Spotlight) to the Gateway via Bluetooth BLE.
The Gateway is connected to the 2.4g internet bandwidth via Wi-Fi / lan cable. Subsequently, the Mesh Gateway Hub which is connected via Wi-Fi / lan cable can be connected with AI Voice Control Ready Devices such as Google Assistant, Amazon Echo (Alexa).When sync to Apple HomeKit, the lights can be switched on within 0.3 seconds.
Much faster than any other APPs!
