Designed for competition BBQ teams, commercial smokehouses, professional chefs, and those who want to cook like them, Signals with built-in Wi-Fi and Bluetooth wireless technology boasts 4 channels of continuous temperature monitoring with all the powerful features and convenience you've come to expect from ThermoWorks.

Finally, a 4-channel alarm thermometer that works with your smart device AND as a stand-alone unit with physical buttons (so you don't have to soil your smartphone). Signals comes with both Wi-Fi and Bluetooth wireless technology onboard so you get a continuous signal and real-time alerts whether you're in a field or across town. Setup is quick and easy without ever needing to read the instruction manual. Signals stands apart from the competition, from its huge, backlit dashboard display and sturdy, self-standing weather-resistant case to its programmable channel names and new high temperature silicone color bands so you know at a glance which channel goes with which probe. Signals uses commercial-grade Pro-Series temperature probes exclusive to ThermoWorks to deliver better accuracy, faster response, wider temperature ranges and longer useful life. Cook more at once and worry less about the results with Signals.

Signals is designed to track temperatures over an extended period of time with moderate-heat cooking methods such as smoking, oven-roasting, deep-frying, homebrewing, and Sous Vide and to be used while grilling. Signals is not meant to be used in place of a digital instant-read thermometer, such as a Thermapen MK4 or a ThermoPop, or used with broiling.

Wi-Fi and Bluetooth Wireless Technology Built In
With the flexibility of Wi-Fi and Bluetooth wireless technology built right in, you'll always stay connected to your smart device. Easy-as-pie setup unlike the other guys.

Free ThermWorks BBQ App
Receive real-time alerts on the go with the ThermoWorks BBQ App on your phone or tablet. Customize channel names, set alarms, view and download graphs. Monitor multiple Signals or your ThermoWorks devices simultaneously using the same app.

Cloud Functions
Signals uses Wi-Fi to store your 10 most recent cooks in the cloud. Access your graphs, Max/Min readings, and alert history at any time in the app, or download them to your phone for archival storage. The cloud keeps a live record during your cooks allowing you to track your temperatures from any phone or tablet at the same time.

Four Channels
Accepts four probes. Comes with three Pro-Series High Temp Cooking Probes and one Pro-Series High Temp Air Probe for monitoring your pit temperature.

Pro-Series Probes
Signals works with all of our Pro-Series probes. ThermoWorks' Pro-Series Probes are the best in the business for accuracy, durability, and heat resistance. Get the confidence that comes with ThermoWorks probes and meters.

Easily identify Each Probe
Input a different four-character name for each channel display (i.e Beef, Pork, Lamb). Plus, Signals comes with 8 High Temp Silicone Color Bands that roll onto each end of each probe, so you can see at a glance which input matches with which probe.

Also Works as a Stand-Alone Unit
Control all functions on Signals from your phone or with the physical buttons on the device. The big, bold dashboard-like display shows the channel name identifier, current temperature, high and low alarm settings, and alarm state for each channel, plus volume level, battery state, and wireless status. Control all functions on the unit with physical buttons or from your phone.

Water Resistant
Molded-in seals for splash-proof protection rated to IP66, safe for outdoor use. NO additional waterproof bags or cases needed.

Includes Battery and Power Adapter
Rechargeable battery delivers up to 16 hours of continuous use. Includes 12V USB power adapter and cord for plug-and-play or recharging the battery.

ThermoWorks Signals 4-Channel Thermometer Review

In my opinion, Signals is very competitively priced and you get a lot of product and a lot of capability for the $229 you spend on this unit. Being able to get more sleep, more work done, etc. without having to sit right there and babysit the smoker alone is worth the cost of the product.
