If you are having difficulty adding a Sengled Smart LED (ZigBee) bulb to a compatible hub or if the bulb has gone offline, please try the following comprehensive troubleshooting to get the bulb added back:
1) Confirm the Model Number (M/N):
First, we must determine if the bulb is a Sengled Smart LED (ZigBee) bulb.
If the model number (M/N) of the bulb starts with an E or a Z, see if it is one of the following bulbs:
If it is, then the bulb is a ZigBee bulb and would require a compatible hub in order to be used.
2) Compatible Hubs:
A hub is the device that speaks the same ZigBee language as the bulbs; the hub is the device that is connected to the router—and thus the internet.
For example, the Sengled Smart hub, SmartThings hub and Echo Plus with built-in hub, are all compatible hubs.
The Echo Dot, Echo, and the Google Home Assistants are not hubs.
The method of adding the bulb to a hub would depend on the hub, one must use the app that corresponds to the hub.
3) Use Conditions:
Next, our Smart LED bulbs—like most LED bulbs—are not meant to be used in the following conditions:
Wall dimmers—with the sole exception of the Tunable White bulbs (Z01-A19NAE26) which can be used on some dimmers; for more information, please see the following article: List of compatible dimmers for the Tunable White Smart LED
Ceiling fan fixtures
Lamp with multiple power settings (i.e. a low/high power lamp, a low/medium/high power lamp—a 3-way lamp—or a dimmer lamp)
Outdoors—with the sole exception of the Sengled Smart LED with Motion Sensor PAR38 Bulb (E13-N11).
4) Resetting & Re-adding:
Once you have confirmed you have a Smart LED (ZigBee) bulb—and if it is not being used in a condition it is not meant to be used in—proceed with the following to add it to your hub:
1) Reset the bulb, like so: https://support.sengled.com/hc/en-us/articles/219648347-How-do-I-reset-a-Sengled-Smart-LED-bulb-
2) Add it to your hub. This will depend on the hub you have. One must use the hub that corresponds to their app.
So, if you have a Sengled hub, then you would use the Sengled Home app—depicted below—to add the bulb, like so: Adding Sengled Smart LED (ZigBee) bulbs to your Sengled Hub
