The proximity wake-up feature is built in as part of Bluetooth® Smart technology.
When the smart device that is paired with your iGrill 2 goes in or out of range, the thermometer will automatically sleep or wake to conserve power. The Bluetooth® indicator LED will blink while not paired and will stay solid while paired, but its status will not change depending on whether the thermometer is asleep or awake. You will continue to receive temperature data and alerts on your connected smart device whether or not the iGrill 2 is utilizing the proximity wake-up feature.
