Meatender Rectangle WiFi PID Controller replacement for Pit Boss grills — Dual-probe, 4 PID modes, Winter Mode

This Meatender Rectangle Upgrade WiFi Controller is a drop-in replacement for Pit Boss horizontal rectangle controllers, adding four-mode PID temperature control, WiFi app access, dual probes and improved cold-weather performance.

If your Pit Boss grill uses a rectangular control board (MPNs like AC03P9, 80014, 80109, 80100, 80117, 80126, 80107, or 80111), this Meatender replacement is built to fit and modernize that same form factor. It supports a wide range of Pit Boss models — including Lexington, Classic, Austin XL, Savannah, Legacy Connected, Navigator, Sportsman, Pro, Competition and Onyx series — and swaps in for both older analog dial controllers and the newer digital rotary PID panels with the same shape.

How does the new controller improve temperature consistency?

The Meatender controller uses four PID programs tailored for grills with cooking areas from about 440 to 1600 sq. in., which helps reduce temperature swings and keeps heat steadier for long cooks. You can fine-tune the setpoint in 1°F increments across a wide 180°F–550°F range to better hold target temperatures for smoking, roasting or searing.

• Four PID modes optimized by grill size and cooking style
• 1°F adjustment resolution for precise control
• 180°F–550°F working range for most pellet cooking needs
• Improved pellet efficiency during long low-and-slow sessions

Can I control the grill remotely and get alerts?

Yes — connect the controller to your WiFi network and use the GrillirG app to change temperature, adjust smoke output, set timers and monitor real-time diagnostics. The app shows error icons for auger motors, fans, RTD probes or hot rods so you can quickly identify and resolve hardware faults.

• WiFi connectivity and app-based control via GrillirG
• Live diagnostic icons for auger, fan, probe and hot rod issues
• Timers, smoke level adjustments and remote setpoint changes
• Compatibility with Android and iOS devices

What meat monitoring and cold-weather features are included?

The board accepts two meat probe inputs and lets you set target temperatures and alarms in the app for accurate doneness tracking. A Winter Mode speeds heat-up and improves stability when ambient temperatures are low, helping maintain reliable performance in colder climates.

• Two probe inputs for dual-zone meat monitoring
• App-based target temps and audible/visual alarms
• Winter Mode for faster warm-up and steadier cold-weather control
• Better temperature hold for long smokes in subfreezing conditions

Does it support multi-user sharing and smartwatch control?

The GrillirG app supports family device sharing so multiple people can monitor temperatures and adjust settings during gatherings. With the app’s Plus Membership, you can expand control to Apple Watch or Android smartwatches for quick, hands-free checks and adjustments from your wrist.

• Family sharing for collaborative cooking and monitoring
• Smartwatch control via optional app membership
• Convenient hands-free adjustments while entertaining
• Useful for teams or shared backyard setups

Who is this for? This Meatender replacement controller is aimed at Pit Boss owners who need a like-for-like rectangular controller swap but want modern PID accuracy, app-based remote control, probe tracking and better cold-weather reliability. It fits hobbyist pitmasters who upgrade older analog panels, families who share grill access, and anyone who wants smarter diagnostics and precise temperature management without changing the grill’s original control opening.
