New sensors can be added to your All New SimpliSafe system in one of two ways.
If you are adding a single sensor, open the Menu on your keypad (using your Master PIN) and select “Devices”, then “Add device” and follow the instructions.
If you are adding multiple sensors, open the Menu on your keypad (using your Master PIN) and select “Setup and Naming”. Use the right rocker to move forward until the Keypad says “Press a button on a device to test and name”. Press the test button on the device (see the manual for details on where to find them), and name the device, then repeat for each sensor.
In the mobile apps select the ☰ icon and select device settings in the top right corner select the + button and follow the instructions.
