Step 2: Connect your Smart Battery

Add a Smart Battery

After you’ve created your account, you are ready to set up your Smart Battery and connect it to Wi-Fi. Before you start, make sure that your smartphone is connected to your home Wi-Fi (note, you need to be connected to the 2.4 GHz band of your Wi-Fi network. Need more info? Click here).

Follow the instructions in your app for the most up-to-date 

To get started, pull the clear tab out of your Smart Battery. You will hear an single beep indicating that your Smart Battery has powered on. If you have a Second Generation Roost Smart Battery you will also see an LED on side of the bottom Smart Module blinking red.

Then select “Add a new device” in the Roost app. If you already have devices in your Roost account, tap the + in the upper right hand corner of the app.

NOTE: You can have multiple physical address locations in one Roost app. Please be sure to add batteries to the correct address. In the example below, the device would be added to the address "My Home." Swiping left or right on your screen will take you to additional address if you have them set up.

Choose which type of device you want to add

To add a Smart Battery, tap on the Smart Battery icon.

Choose a location for this device

Next, indicate the location of the alarm where your Smart Battery will be placed. You can add a custom name for a location if desired. You can always change this later.



"Connect to your Roost Device" screen

If you have a Second Generation Roost Smart Battery, and an LED on the side of the battery is blinking red, your device is broadcasting a Wi-Fi signal. Please follow the instructions in the app to connect to the Roost-device network. For more information on whether you have an original or a Second Generation Roost Smart Battery, please click here. 

  • Solid blue bottom: If your battery has a solid blue color bottom (opposite the power terminals), you have an original Roost battery. This device does not broadcast a "Roost-device" Wi-Fi signal. Simply tap, "Could not find" and follow the instructions in the app.
  • Blue bottom with white Roost logo: If your battery has a blue color bottom with a white Roost logo (opposite the power terminals), you have a Second Generation Roost Battery. If you see an LED blinking red after you remove and reattach the Smart Module, you have a Second Generation Battery with the silent setup firmware. Your battery can broadcast the Roost-device-xxxx Wi-Fi signal.





Enter your Wi-Fi password

During setup the Roost app will send via an encoded audio signal your Wi-Fi network (SSID) name to the Roost battery. Please make sure that your Wi-Fi network is working and that you enter in the correct password for your Wi-Fi network. Please note: The password you need to enter in the screen below is for your Wi-Fi, not your Roost Account password.

IMPORTANT: During setup, you must be connected to a 2.4 GHz Wi-Fi network that is in physical proximity to where the alarm with the Smart Battery will reside.




Before you continue, does your Roost package look like this inside?

If you have foam packaging with a speaker, please click here to continue your Step 2 Setup instructions. If you do not have this packaging, please continue with the "Set up Connection" step immediately below this image.


Set up Connection

When you’ve entered the location and Wi-Fi information for your Smart Battery, it's now time to start the important audio connection process that will link your Smart Battery to your Roost account.

As part of setup, the Smart Battery will play a 10-second audio tone. We recommend that you are in a quiet area and get ready to connect by taking the following steps:

Roost App Step 1: If you have not done so yet, please remove the pull tab from the battery. Please be sure you do not dislodge the Smart Module (the small rectangular piece at the bottom of the battery). You should hear a single beep when you remove the pull tab.


Roost App Step 2: Locate your phone's speaker.

  • On the iPhone, the speakers are located on the bottom of the phone
  • The speaker location on Android phones varies by model. The speakers are usually on the front or back of the phone. If you are unsure where your speaker is located, you can refer to our Help Center article: How do I find the external speaker on my Android phone?

You'll be asked to turn up the speaker volume on your phone so that the Roost battery can hear the encoded audio signal from your phone.


 Roost App Step 3: Place the Roost battery so that its sound hole is near the speaker on your phone, about 1/4" to 1/2" (1 cm) away.


Begin the audio pairing process by tapping "Connect." The Roost app will transfer encoded data with your Wi-Fi network name and password to the battery. The connection process may take up to 60 seconds. After the process completes, you'll see the success screen.



If you do not have success with connecting and instead see the screen below, please count the beeps that you hear and tap Troubleshooting tips in your app.
