Does Sleep / Sleep Analyzer emit Bluetooth or Wi-Fi signals while I sleep?
When it is first plugged into power, Sleep / Sleep Analyzer 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.
Sleep / Sleep Analyzer 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. Sleep / Sleep Analyzer doesn't emit Wi-Fi signals while you sleep. However, it emits short-burst Wi-Fi signals to trigger IFTTT events when you get in and out of the bed.
