Remote control for your Big Green Egg! Remotely manage and monitor cooking temperatures, monitor the temperature of your food, view graphs of your cooks and receive alerts when your cook is finished or when the EGG temperature is too high or low. The EGG Genius app works with an EGG Genius WiFi Temperature Controller to: • Control the device through your smartphone, tablet or computer to remotely manage and monitor the internal temperature of the EGG • Monitor the temperature of your food; view graphs of your cooks • Receive alerts when your cook is finished or when the EGG temperature is too high or low • Quickly reach your desired cooking temperature as the blower ramps up to fan the lighted charcoal; once the desired temp is reached, the variable speed blower automatically adjusts the blower speed to optimize the set temperature. • Automatically lowers the pit temperature to keep your food warm when the cook is complete. • Detects the sudden temperature drop from opening the dome and turns the fan off temporarily to avoid over-stoking the fire. • In the case of a power outage, the unit continues running at the saved set temperature and reconnects to the WiFi network automatically when power returns. • Use up to 3 meat probes at once – additional meat probes with Y-cable can be purchased separately. • Powered by Flame Boss® Big Green Egg® and EGG® are Registered Trademarks of Big Green Egg Inc.

The Combustion App includes the latest firmware updates for Predictive Thermometers and other Combustion Accessories including Boosters, Displays, Giant Grill Gauges and other forthcoming products. Firmware updates improve core functions including time-to-cook predictions, longer battery life, and can add new features. MeatNet™ Cloud – for functionally unlimited range!

Advanced graphing on the Combustion App helps you visualize exactly how heat moves through your food. You will understand the relationship between ambient cook temps and surface temps. And how surface temps really control how long things take – and how evenly food cooks. It may shock you to find out the oven temp (or grill temp) you set is not the same as the food is actually experiencing! The Combustion Inc app puts all that knowledge in front of you – with instant feedback, so you’re not just cooking better, you’re also learning as you go. And learning has never been so delicious.
