Here are some detailed instructions to connect Zigbee lights to Echo Plus:
For compatible Zigbee certified lights (like Philips Hue), set up is easy! First install your Smart Home device within 30 feet of your Echo plus, or another device connected to Echo Plus & power off any Bluetooth connected devices. Next, say, "Alexa, Discover my devices," and then put the smart home device into pairing mode by powering it on. You can also refer to the device's instructions for information on how to place your device in pairing mode.
To connect a smart home device to Echo Plus in the Alexa app:
From the Menu, select Smart Home
2. Select Devices, and then select Add Device.
Place your device in pairing mode.
Q: Do I need more than one Echo Plus to control smart home products in my home?
A: No, if you want voice control in multiple rooms you can set up supported smart home devices by connecting them to an Echo Plus and then use Dots or other Echo products in additional rooms to control these devices by voice.
