Step 2: Connect your Leak Detector

If you purchased your leak detector from Roost after November 1, 2017, you have a Second Generation Roost device. The model number on the Roost package sleeve and the Quick Start Guide is RSW-200A. Please follow the instructions for Roost Second Generation leak detectors. 

Connecting Second Generation Roost leak detectors

Roost Second Generation leak detectors connect to your Wi-Fi network using a silent connection method where the Roost device becomes a temporary Wi-Fi hotspot. If you have an Original Roost detector, your leak detector can only connect via audio provisioning (see below)

After you’ve created your account, you are ready to set up your Smart Leak Detector and connect it to Wi-Fi. Before you start, make sure that your smartphone is connected to your home Wi-Fi.

Follow the instructions in the Roost app, taking careful note of the step where you leave the app to connect to the (temporary) Wi-Fi network "Roost-device-xxxx" After you connect to this network, return to your Roost app and follow directions to continue the setup.

For additional help, please see our setup video for Second Generation Roost leak detectors.

Connecting Original Roost leak detectors

After you’ve created your account, you are ready to set up your Smart Leak Detector and connect it to Wi-Fi. Before you start, make sure that your smartphone is connected to your home Wi-Fi.

To get started, pull the red tab out of your Smart Leak Detector. You will hear an audio single beep indicating that your leak detector has powered on, and you will see a green LED next to the Roost logo on the top of the detector blinking green. Your device is ready to set up when this green light is blinking.

Then select '+' at the bottom of the Roost app to add a new device.

NOTE: You can have multiple physical address locations in one Roost app. Please be sure to add devices to the correct address. In the example below, the device would be added to the address "Vacation 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

  • Please be aware that the first time you add a device at this point, the Roost app will ask you to “Allow Roost to access this device's location.” We recommend you allow the application to see your location. Allowing Roost to know your location will let others know if you’re near the device when it sounds.

Tap on the Smart leak detector icon.


Choose a location for this device

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

Note: If you select a Custom Location, you will need to name your location and your device. For example: Location "Attic" and device name "Water heater."

Choose a Name for this device

If you select the location of Kitchen, Bathroom, or Master Bedroom, you'll be given some optional device names, such as Sink, Dishwasher, Refrigerator, or Toilet. You can also choose a custom name such as "David's sink" or "Master bath Toilet". 

If you select a location of Hallway, Hallway-Upstairs, Basement, or Garage, you will need to name your Leak Detector, for example, "Hot Water Heater" or "Laundry Sink." 

 Connect to Wi-Fi

The app will then attempt to connect to the Wi-Fi network (SSID name) on which your smartphone is connected. 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 Wi-Fi network that is in physical proximity to where you will place your leak detector.


Follow the set up steps in the Roost app

Follow each step in the Roost app, taking note of the screen images and instructions on each app page.

Take note of where your speakers are located and make sure the leak detector is positioned with its sound holes near your phone 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? 

If you do not have success with connecting and instead see the following screen,check your Wi-Fi connection and make sure you have entered the correct Wi-Fi password in the Roost app. 


Tap "Try Again." If you are still not getting a Success screen, note the number of beeps (0, 2, 4, 6 beeps are error codes) and refer to the Help Center article: My Smart Leak Detector is beeping during set-up, what does this mean?
