HunGrill Smart WiFi Replacement Kit for Masterbuilt Gravity Series 560/800/1050 — WiFi Controller, Extended RTD Probe, Splashproof

HunGrill's Smart WiFi Control Panel Replacement Kit restores full smart control to Masterbuilt Gravity Series 560/800/1050 grills with a WiFi-enabled controller, longer RTD probe, and a splashproof 12V power adapter.

If your Masterbuilt Gravity Series grill lost connectivity or its temperature probe stopped working, this kit gives you a direct, compatible swap for the OEM electronics — without buying a new grill. Designed to fit the listed MB model numbers and replace the original part numbers, the HunGrill pack reinstates app-based remote monitoring, precise food temperature sensing, and weather-ready power for reliable backyard smoking and grilling.

Will this replace my existing Masterbuilt controller and sensor?

Yes — the HunGrill kit is engineered for direct compatibility with Masterbuilt Gravity Series 560, 800, and 1050. It replaces the OEM controller, RTD probe, and power adapter part numbers specified for those models so installation is straightforward for most users familiar with basic grill maintenance.

• Fits models: 560 / 800 / 1050 (MB20041220, MB20041320, MB20040220, MB20041020, MB20040221, MB20040122).
• Replaces OEM controllers: 9904190036, 9904200043, 9904200004.
• Replaces RTD probe: 9904190024 and power adapter: 9004190216.

How do I control the grill after installing this kit?

Once the HunGrill controller is installed and connected to your home WiFi, you can operate the grill from the onboard digital panel or through the app on your smartphone. The app sends remote set points and alerts, so you can monitor grill and food temperatures without staying near the unit.

• WiFi control for remote temp changes and alerts.
• Onboard digital panel for local programming and monitoring.
• Push notifications for cook completion or temperature deviations.

What performance features help me get consistent results?

The kit includes precision features that help maintain stable temperatures and more accurate cook control. Dual temperature monitoring (grill and food), a programmable timer, and Boost Mode (for 800 & 1050) give you more predictable outcomes across long smokes or fast sears.

• Extended RTD probe for accurate in-chamber food readings.
• Boost Mode increases airflow/fuel burn for fast temperature recovery (800 & 1050 only).
• Programmable timer and dual temp display for consistent doneness.

Will this work in cold or damp conditions?

The HunGrill controller supports a Winter Mode that increases pellet burn to reduce temperature swings in cold weather, and the included power adapter has an IP44 splashproof rating for outdoor use. For full functionality, ensure the controller firmware and app are updated to their latest versions.

• Winter Mode available via the controller Settings menu.
• IP44-rated 12V 1.5A power adapter with 16ft cord for safer outdoor placement.
• Firmware/app updates recommended for best reliability and features.

Who is this for? This replacement kit is ideal for owners of Masterbuilt Gravity Series 560, 800, or 1050 who need a reliable, smart electronics refresh. It suits backyard grillers who want app-based control restored, pitmasters who need accurate in-food temperature readings, and anyone replacing a failed controller, probe, or power adapter with a directly compatible, weather-ready solution. The package gives a practical, cost-effective path back to full digital grilling capability without changing your smoker or cook style.
