Traeger Pellet Sensor BAC523 for Ironwood 650/885 & Pro 575/780 — WiFIRE Monitoring, LED Hopper Light

The Traeger BAC523 Pellet Sensor is a smart hopper sensor that monitors pellet levels and sends low-pellet alerts through the Traeger App so you can cook without unexpected interruptions.

Designed for D2 WiFIRE®-enabled Traeger grills, this compact accessory installs directly into the hopper to track pellet supply and integrate seamlessly with your grill’s WiFi control. Once fitted, the sensor communicates pellet status to the Traeger App, lighting the hopper for easier viewing at night and giving you peace of mind during long smokes or busy backyard gatherings.

How does the pellet sensor keep me from running out mid-cook?

When installed, the BAC523 continuously senses how much pellet fuel remains and relays that information to the grill’s WiFIRE system. If levels dip below your set threshold, the Traeger App sends push notifications so you can top up before it affects temperature or cook time.

• Real-time pellet level monitoring via WiFIRE integration
• Automated low-pellet alerts delivered to your phone
• LED illumination inside the hopper for quick visual checks

Will it work with my Traeger grill models?

The BAC523 is engineered specifically for Traeger D2 WiFIRE-enabled grills and fits the Pro 575, Pro 780, Ironwood 650, and Ironwood 885 models. Installation mounts into the hopper using the included hardware and once connected the sensor pairs automatically with the grill’s existing WiFi system.

• Compatible with Pro 575 and Pro 780 models
• Compatible with Ironwood 650 and Ironwood 885 models
• Mounting hardware included for straightforward installation

How hard is installation and setup?

Installation is designed to be user-friendly and requires no special tools beyond what’s provided. The sensor mounts in the hopper, connects to the D2 system, and shows up in the Traeger App so you can set notifications and check levels from anywhere.

• Mounts directly into the hopper—no cutting or wiring modifications
• Includes all mounting hardware for a quick DIY install
• Auto-integrates with WiFIRE once installed

What practical features help during long cooks or at night?

A built-in LED gives you a clear view of pellet depth in low light, and the app alerts remove the need for constant manual checks. Together these features reduce the chance of fuel-related interruptions on overnight smokes or extended grilling sessions.

• LED light illuminates hopper contents for late-night checks
• App alerts help you plan pellet refills ahead of time
• Continuous monitoring supports uninterrupted temperature control

Who is this for? The Traeger BAC523 Pellet Sensor is ideal for anyone who runs D2 WiFIRE-enabled Traeger grills—especially those who do long smokes, overnight cooks, or frequently manage multiple grills. It’s a practical upgrade for weekend pitmasters and busy hosts who want fewer surprises and smoother, more reliable cooks.
