xiaomi E27 Yeelight Smart LED Bulb

Introduction

Yeelight sunflower is a wireless, smart, scene lighting system. It can be installed into your home Wi-Fi network, and all the bulbs form a system with control box automatically. You may control the bulb to change their color and brightness with smart device such as smart phone or pad, also you may save the setting to a scene and recall it at next time. Now the app supports iOS version 5.0+ and Android 2.3.3+.

  1. Starter pack
    For the starter pack, there are 3 yeelight bulbs and 1 control box; it is the base lighting system.
    1. The bulb
      The yeelight sunflower bulb is a LED lighting bulb, in which there is a wireless sending/receiving component working via Zigbee signals. The bulb receives signals from control box and changes color and brightness to what you want.
    2. Control box
      The control box is a LAN (local area network) to the Zigbee bridge, which transforms the smartphone control commands (Wi-Fi signals) to Zigbee signals. The Control box has one LAN socket, with which it can be connected to your home Wi-Fi AP. When it boots up, an IP address will be assigned and your smartphone can search and connect to it via Wi-Fi. The following figure shows the interfaces on the control box.
  2. Single pack
    For the single pack, there is only one yeelight bulb in the package. The single pack cannot be used independently, and it should be used to extend the bulb numbers for a starter pack. Please refer to Extra bulb via single pack in the Installation section on how to extend.
