Installation Instructions:
The following instructions are applicable to adding your 
Smart LED bulb to an Alexa Device that supports BLE 
Mesh bulb.
Note: Please ensure your Amazon Alexa 
device is setup before adding the Smart bulb. 
It needs to have the latest software upgrade. 
You can try “Alexa, is my software up to date?” 
to trigger software update, then add the smart bulb.
• Sengled Smart Bluetooth Mesh LED bulbs are created 
for Frustration Free Setup. If you have purchased the 
bulb from Amazon using the same Amazon shop 
account as your Alexa App account, and had selected 
“Link to my Amazon account to simplify setup” before 
paying for them on Amazon shop, you can install the 
bulb close to your compatible Alexa device and power it 
on. The bulb can join the Bluetooth network automatically. 
• You can also try the traditional way to set up bulb by 
asking “Alexa, discover devices.”
After the bulbs get discovered and connected with the 
Echo device, you will receive a notification from Alexa app. 
You may also receive a voice prompt from your Echo 
device if you have a single Echo device at home. 
Mesh Network Setup
If you want to have multiple bulbs setup for dierent rooms, 
especially rooms out of the range of the Alexa device’s 
Bluetooth signal range, you can utilize Mesh Network setup 
to extend the range.
1. First, Setup the smart bulbs close to the Alexa device. 
2. Switch o the bulb and move it 
further away from the Alexa device 
and make sure it’s within Bluetooth 
range of another active Bluetooth 
bulb, which is connected on the 
network as a node. This will form 
a Bluetooth Mesh network. Each 
connected bulb will connect with
other bulbs (nodes) within the range. 
Congratulations on successfully set up your smart bulbs!
