When it is first plugged into power, the Sleep will be discoverable via Bluetooth for 30 minutes so that it can be set up. After the setup, data is transmitted via Wi-Fi and the device is no longer discoverable via Bluetooth.

The Sleep does not maintain a continuous Wi-Fi connection with your router. A Wi-Fi connection is used during the setup, and to transfer data as needed. The Sleep may emit short-burst Wi-Fi signals (less than 2 seconds long) while you sleep to transmit data such as changes in your sleep state or to trigger IFTTT events by getting in and out of the bed.
