Troubleshooting Firmware Updates for Combustion Devices

This article provides helpful guidance for updating Combustion Predictive Thermometers, boosters, and displays. We understand that firmware updates can sometimes be challenging, and we're here to help you through the process. You may notice that firm

Prediction missing or slow-to-predict

Prediction will usually resolve about 10% through the cook and get more accurate as it gets closer to being done. With very long cooks (e.g. smoked brisket), the core temperature will tend to "stall" at a certain temp for a long time. Predictions wil

Not seeing surface temp

Surface temp is activated when a target (predict) temp is set (cooking mode). Set a target temp using either the app or the Display.

Not seeing graph

In cooking mode, tap any temp to show the graph. OR. Tap the 3-dot action button to show/hide the graph:.

Poor range (smoker, grill, or sous vide)

Move the first range extender (Booster or Display) as close as possible to the cooking apparatus. If possible, establish a clear line-of-sight between MeatNet™ tools. Common radio obstructions include metal, water, brick, reflective glass, and human

Display/app stopped showing temp (while cooking)

Disconnected - move closer or reposition to avoid radio obstacles.

Booster misbehaving

Not boosting?. Remove CPT from Booster to activate range-extending mode. Not blinking?. Press the button (light) to wake. Booster not communicating with Display?. Follow the directions in "Booster set-up" to link multiple tools:. Start by updating th

App not connecting/intermittent disconnects

Restart your phone to clear the Bluetooth cache (yeah, it’s annoying). Some phones (iOS) have a habit of holding stale Bluetooth connections and all the "parking spots" may be full. You may need to do a hard reset.

CPT not connecting to Display and/or App

"Not connecting" is a general symptom that can have a few different causes. Remove CPT from charger/booster. It could mean the thermometer's battery is dead - that's usually because there's something interfering with charging. Hey, it happens. If the

Firmware update stuck on "Updating: starting"?

If the firmware update "hangs", it may go a long time without completing the update (or seeming to). This is usually an issue with the device (phone) itself. Search the exact instructions for your device (hard restart + phone model in your search bar

Mid-update error?

First, let's make sure only one Combustion tool is active - just the thermometer. Could you please turn off your other tools? To do this:. Next, let's ensure the Combustion app isn't running anywhere else, like on an iPad. Now, restart the app on you

Display flashing red + screeching

Using the thermometer above these temps may damage your thermometer and will void the warranty. The "red alert" is a warning that your thermometer is in the danger zone. TEMPERATURE LIMITS:. If the lower sensors have exceeded safe operating temp, the

Turning off probe

We've made some exciting improvements to your probe. A few months back, we updated the firmware to work even better with moist cooking methods like sous vide. Pretty cool, right?. Also, we've tweaked how the thermometer behaves when you're not using

CPT not charging?

A helpful tip that might get your thermometer charging again: A little TLC for that metal contact on the bottom. Don't worry if it looks clean – sometimes there's an invisible layer of cooking oil that builds up over time. Here's what you can do:. Wi

Do I need to calibrate my Predictive Thermometer?

Great question! Let's dive into this:. Good news! Our sensors are designed with a zero-calibration circuit. This means they don't typically need calibration. We do thoroughly check each thermometer during manufacturing.
