- Wireless Probe: Features dual sensors for internal food temperature (14°F to 212°F / -10°C to 100°C) and ambient temperature (14°F to 572°F / -10°C to 300°C). Constructed from surgical-grade 316 stainless steel with a ceramic handle. It is IP67 waterproof and dishwasher safe.
- Host Unit: A multi-functional display base showing real-time food and ambient temperatures, as well as battery levels for both the probe and host. It allows for direct temperature setting and provides audible alerts. The host unit is magnetically attachable.
- CHEFBBQ App: A companion application for iOS and Android devices that provides remote monitoring, customizable temperature settings, USDA meat presets, intelligent alerts, and data graphing.
Setup
1. Charging the Device
Before first use, fully charge both the probe and the host unit.
- Probe: Insert the probe into the host unit. A 10-minute charge provides approximately 24 hours of continuous use.
- Host Unit: Connect the host unit to a USB power source using the provided USB-A to USB-C charging cable. A full charge takes approximately 3 hours and provides over 120 hours of runtime.

Operating Instructions
1. Probe Insertion Guidelines
Proper probe insertion is crucial for accurate temperature readings.
- Insert the probe into the thickest part of the meat, avoiding bones or gristle.
- Ensure the probe is inserted past the 'insertion line' (the notch on the probe shaft) so that both the internal and ambient temperature sensors are correctly positioned.

2. Using the Host Unit
The host unit provides standalone operation without the need for the app.
- The display shows real-time internal food temperature, ambient temperature, and battery levels.
- Use the buttons on the host to set your desired target temperature.
- The host will provide audible alerts when the target temperature is reached.
- Press the '°F' button to switch between Celsius and Fahrenheit.
3. Using the CHEFBBQ App
The app offers enhanced control and monitoring features.
- Select Meat Type: Choose from various USDA-recommended presets for different types of meat (e.g., Beef, Chicken, Pork, Lamb, Fish).
- Set Doneness: For each meat type, select your desired doneness level (e.g., Rare, Medium, Well Done). The app will automatically set the corresponding target temperature.
- Custom Temperature: You can also set a custom target temperature if desired.
- Monitor Progress: The app displays real-time internal and ambient temperatures, cooking graphs, and estimated cooking times.
- Alerts: Receive alerts on your phone when the target temperature is reached. Both the host unit and your phone will notify you.
