Setup
1. Physical Installation
- Attach the Blower: Select the appropriate grill adapter for your Kamado-style grill (e.g., Big Green Egg, Kamado Joe, Primo, Grill Dome, Akorn Kamado, Vision Classic). Insert the WiFi controller's blower unit into the grill's bottom vent opening. Ensure a secure fit to prevent air leaks.
- Connect Probes: Plug the high temperature pit probe into the designated 'Pit' port on the controller. Secure the pit probe inside your grill, typically clipped to the cooking grate, ensuring it does not touch the food. Plug the high temperature meat probe into the 'Meat' port and insert it into the thickest part of your food, avoiding bone.
- Power On: Connect the power supply to the controller and plug it into an electrical outlet. The device will power on automatically.

Operation
- Set Target Temperatures: Use the Flame Boss app to set your desired pit temperature for your cook. You can also set a target internal temperature for your meat.
- Monitor Progress: The app allows you to view real-time graphs of your cooking sessions, showing both pit and food temperatures.
- Adjust Pit Temperature: You can adjust the pit temperature remotely from your smartphone or connected device.
- Meat Alarms & Alerts: Set a meat alarm to automatically adjust the pit temperature when your desired meat temperature is reached. Receive text message alerts when your meat is done cooking or if the cook temperature is too high or low.
- Voice Command: The device is compatible with most voice assistants for convenient voice command control.
- Lid Open Detection: The patented software and variable speed blower automatically detect when the grill lid is opened, pausing the fan to prevent temperature spikes and resuming once the lid is closed and temperature stabilizes.
Maintenance
- Clean Probes: After each use, allow probes to cool completely. Wipe them clean with a damp cloth. Do not immerse the probe cables or the main controller unit in water.
- Store Properly: Store the controller and probes in a dry place when not in use. The included carrying case is ideal for this.
- Check Connections: Periodically inspect all cable connections for wear or damage.
Troubleshooting
- Connectivity Issues: If the device fails to connect to WiFi or Bluetooth, ensure your router is broadcasting on a 2.4 GHz frequency (802.11B, G, or N). Try restarting your router and the Flame Boss unit. Ensure the device is within range of your WiFi signal.
- Inaccurate Temperature Readings: Verify probes are correctly inserted and not touching bone or the grill grates. Ensure probes are clean and undamaged.
- Fan Not Operating: Check power connection. Ensure the lid is closed and the pit temperature is below the target temperature. The fan will pause if the lid is open.
- Temperature Fluctuations: Ensure the grill adapter is securely fitted to the vent to prevent air leaks. Check that the grill lid is properly sealed.
