The iGrill mini is a great Bluetooth grill thermometer with a meat temperature probe that operates with a smartphone (Apple OS or Android). Therefore, the iGrill mini grill thermometer does not have a display; everything is controlled centrally through the iGrill app. It offers a range of 45.8 meters outdoors, a temperature range of -50 °C to 380 °C, and a battery life of 150 hours.
