1) Confirm the Model Number (M/N):
First, we must determine if the bulb is a Sengled Smart Wi-Fi LED bulb.
Below is an example photo of where the bulb's model number (M/N) information can be found:
If the model number (M/N) of the bulb starts with a W, see if it is one of the following bulbs:
If it is, then the bulb is a Wi-Fi bulb and can be setup using the Sengled Home app.
2) Use Conditions:
Next, our Smart LED bulbs—like most LED bulbs—are not meant to be used in the following conditions:
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)
Note: Before getting started, do not power the bulb on first. This may cause it to fall out of its three-minute pairing mode.
Make sure your phone is connected to your home’s 2.4 GHz Wi-Fi—i.e. the Wi-Fi to which your wish to setup the Sengled Wi-Fi bulb.
Open the Sengled Home app to add the Sengled Wi-Fi bulb.
From here, press the three dots in the circle in the top right corner. Then, press “Add Device”.
Tap on “Wi-Fi LEDs and Accessories”.
Once you are sure you have a Sengled Smart Wi-Fi product, press "Confirm".
Power the Smart Wi-Fi bulb on. The bulb will blink, or flash, to indicate it is in pairing mode. Once that is done, press "Next".
If the bulb does not blink upon power up, reset it—like so: How do I reset the Sengled Smart Wi-Fi LED bulb?
Note: The Sengled Smart Wi-Fi LED bulbs cannot be used on dimmer switches. This would include wall dimmers, ceiling fan fixtures and 3-way lamps (lamps with low, medium and high power settings built-in).
Furthermore, the Sengled Smart Wi-Fi LED bulbs are not meant to be used in fully-enclosed fixtures.
Additionally, the Sengled Smart Wi-Fi LED bulbs are not meant to be used outdoors or in restrooms due to concerns of humidity damage.
Now, tap the "Go to Wi-Fi Settings" button to go to the Wi-Fi settings page of your iOS device.
Connect to the Wi-Fi made by the Wi-Fi bulb; then, only when there is a checkmark next to that Wi-Fi, go back to the Sengled Home app.
Now, go back into the Sengled Home app. The app should automatically take you to the "Select a Wi-Fi network to connect" page; if it does not, press the "Connected to "Wi-Fi Device" option at the bottom of the page when you go back into the Sengled Home app.
When on the "Select a Wi-Fi network to connect" page, select your router's 2.4 GHz Wi-Fi network.
Type the password in for your Wi-Fi network.
Press the "Show" icon to see the password you have typed as one of the most common reasons for a Wi-Fi device failing to setup is that the password that was entered was incorrect (the wrong password was used, a character or symbol was omitted, capitalization, etc).
Once you are certain you have typed in the correct password, press "Next".
Note: Your iOS device may let you know that the Sengled Home app wants to join the Wi-Fi network created by the Sengled Wi-Fi bulb—if so, tap "Join".
From here, the app will attempt to setup the bulb; if things are going as planned, you should see the bulb flash a few times within the first 30 seconds of the app trying to connect the bulb to your Wi-Fi.
Once the bulb is added, you will be on a page that says “Congratulations”. Feel free to move the bulb to the desired location of use; keep in mind that the range of the bulb from the router is based in 2.4 GHz Wi-Fi so it can only be used in an area where your 2.4 GHz Wi-Fi signal reaches.
From the “Congratulations” page, we can assign the bulb to a room in the Sengled Home app. In this example, the bulb is physically in the dining room, so we will assign the bulb to the “Dining Room” in the Sengled Home app. To do this, since that room has not been created yet, press the “Add Room” button.
In the “Add a New Room” pop-up, we tapped on “Dining Room”; then, we tapped on “Ok”.
After that, the bulb will be renamed based upon the room it is in. The automatically generated names make it much easier to identify and organize the bulbs if you wish to connect them to your Echo/Alexa or Google Assistant.
If the location and name of the bulb is to your liking, press “Done”.
