Signals is a Wi-Fi–connected, four-channel BBQ control center engineered for long, low-and-slow cooks. Use it as a standalone monitor at the grill or connect to the ThermoWorks App for real-time graphing, cloud logging, and remote alerts from anywhere. BBQ professionals rely on Signals as their operational hub, managing multiple proteins and pit temperature with full visibility across every channel.

Monitor up to four probes simultaneously with ±1.8°F accuracy and independent alarms for each channel. Built-in Wi-Fi and Bluetooth® stream live temperature data to the app, while physical buttons and a large backlit display maintain full control without a phone. Commercial-grade Pro-Series® probes deliver fast, accurate readings, and the rugged splash-resistant housing withstands demanding outdoor environments. Pair with a Billows® fan to automate pit temperature control and maintain steady heat during extended cooks.

  • Monitor Multiple Temps at Once: Track up to four channels — meat, pit, or both — on one clear display.
  • Powerful App Control and Tracking: The ThermoWorks App lets you monitor, graph, and manage all four probes remotely with customizable alerts.
  • Stay Connected Anywhere: Wi-Fi and Bluetooth® send live temperature data and alerts to your phone or tablet.
  • Get Alerts When It Matters: Set high and low alarms for each probe and step away knowing you’ll be notified instantly if things drift.
  • Works With or Without the App: Use Signals as a standalone alarm thermometer or control everything through the ThermoWorks App.
  • Built for Outdoor Cooking: IP66 splash-resistant housing, strong magnets, and a stable base keep Signals secure near the grill or smoker.
  • Use Professional Grade Probes: Includes Pro-Series High Temp Cooking Probes and an Air Probe for pit monitoring.
  • Expand With Billows: Add a temperature control fan to automatically regulate pit temps during long cooks.
  • Rechargeable for Long Cooks: Built-in battery delivers up to 16 hours of wireless use; included adapter provides continuous power when needed.

Reviews

Very short usage life

"I love this product, but. . . I don't think it's made very well. I've had it for several years but I'm only a home user that maybe smokes pork shoulders 1-4 times per year. That means, at most, I've used this product 20 times. Today, it lost wifi connectivity and the screen was showing garbage so I rebooted it. It reconnected to wifi but one of the temp probes began malfunctioning. About an hour later, wifi dropped again so I rebooted again. This time, wifi never came back and two sensors were providing inaccurate data. About an hour later, the unit completely failed and will not turn on and will not reset. For $250, it should be a robust and reliable product which it is not."

"Great product keeps my WSM within 2f of my target temperature. Wish I would have started with this!"

— Scott N. (5/5)

Depend on it!!

"I've had a Signals for a while. It stopped working, this is the replacement. I own a BBQ food truck and Signals allows me to sleep while cooking."

— Jefferson F. (5/5)

Signals + Billows + Kamado Joe = Cheating

"For years I was a purist - I took a lot of pride manually controlling the airflow from the top and bottom vents of my Kamado. Finally bought the Signals + Billows and this is just cheating! 1) The Kamado was up to temperature (225) in under 10 minutes - unreal. 2) I have never been able to maintain a consistent 225 temperate for hours - I mean so consistent 3) It is fun to hear the Billows "pulsing" air in to the Kamado to maintain temperature Buy once, cry once have been smokes the rest of your life! I just regret waiting this long to purchase it!"

— Robert S. (5/5)

As promised!

"The Signals console is accurate and weighty. It has the capacity to activate the Billows Fan, the fan needs another power source to power up. The setup is fast. Connectivity with the APP enhances the users pleasure and temperature adjustments easier on the APP. I am using a drum smoker and it performed flawlessly. 1st was mac n cheese @ 325°, 2nd was meatloaf @375°, Finally a London Broil @225°. The Signals brain followed the temperatures in-putted. It is Everything that a meathead, like me, wants. Thanks to ThermoWorks, I have achieved new status"

— Garritt D. (5/5)

Great product! I really appreciate

"Great product! I really appreciate the graph feature. It really helped me get better with my fire box management."

— Zach A. (5/5)

So far so good

"I’ve used it one time with the billows to keep the big green egg at a low temp that I couldn’t do prior. Had a roast on for 6 hours & it kept the temperature right where I wanted it."

— Michael C. (5/5)

"Many things that i like about this Signals Alarm are the 4 chanells and WiFi connection also how it’s built and look amaze!!"

— Tong (5/5)

Signal thermometer very dissatisfied!!!!!

"Extremely weak Bluetooth connection and will not connect to the wi-fi network! Highly disappointed. I have the smoke thermometer and love it!"

— Andy W. (1/5)

Upgrade

"This is an upgrade from my Flame Boss. Not even comparable."

— Matthew L. (5/5)

Q&A

What dose HHH mean
HHH could mean a couple of different things. Either the temperature you're reading is above 572°F, or the probe or cable is damaged. You can give our Tech Support a call if you have any questions. 801-756-7705
