The Signals is a new four-channel Wi-Fi and Bluetooth remote read thermometer from ThermoWorks. Four channels meaning it can monitor up to four temperatures at once, but it also can be used as a stand-alone thermometer. It easily connects to your smart device using the ThermoWorks BBQ App. From there you quickly set up an account with ThermoWorks to connect the Signals to their cloud-based service. You also have the option with this app to connect via Bluetooth if no internet is available. I think this is the first ThermoWorks remote read thermometer that gives you all three options without the need for additional hardware. This is exciting indeed!

Here’s what you get in the package

The Brains:

The main unit of the Signals is robust. All four channels read on the splash-proof display at the same time. It is equipped with magnets on the back of the unit to accommodate storage. I stick mine right on the fridge in the garage. Simple as this sounds, I think this is a fantastic feature. Please keep in mind these magnets are not intended to mount your Signals on a hot grill.

The main unit operates at a temperature range of 32°-122°F. The display backlight button is easy to access and stays on for 20 seconds.

The unit has a built-in rechargeable battery that should give you 16 hours of operating time. The charging port is USB C. The charging cable and 12 V power supply is included, which can also be used to run the Signals from a 110 V outlet while in use.

It’s important to note that this power supply is 12 volts, as most USB power supplies are not. You need to be sure to use the Signals power supply when charging. It is clearly marked.

High Temp Cooking Probe with Grate Clip. 

The Probe:

The Signals comes with four total Pro-Series cooking probes: three High Temp Cooking Probes and one High Temp Air Probe with Grate Clip.

The high temp probes in the Pro-Series are thermistor type, good general-purpose probes. The transition area of these Pro-Series probes is well built. This is the area where the probe connects the cable. The length of the cooking probes reaches the center of large roasts and turkeys. Here are the rest of the probe stats:

Cable Max Temp: 700°F (370°C)

Transition Max Temp: 644°F (340°C)
Transition Dimensions: 1.4 L x 0.35 inches dia. (35.6 L x 8.9 mm dia.)
Probe Range: -58 to 572°F (-50 to 300°C)

Cable Length: 47 inches (1.2m); Warranty: 6 months

High-Temperature Probe Rings:

     High Temp Probe Rings.

Included with Signals are eight colored silicone probe rings. These probe rings are rated to 600°F (315°C). Put one on each end of a probe to help identify which probe is connected to which channel on the Signals when using multiple probes. The set includes two blue, two red, two green and two yellow probe rings, one for each end of up to four probes. As a word of caution, be sure to wipe down these probe rings after each use. If not, the ring of the probe end of the cable will darken with a heavy layer of smoke and become difficult to clean.

A few things to note

While the Signals is slated to be able to store up to 10 cook graphs on the cloud-based service, that feature is not available to me at the time of this article; I’m not sure if this is across the board or just with my Signals. I contacted ThermoWorks customer service and was advised that my issue was forwarded to the app developers for review and to check back for app updates.

Bottom line

For me, ThermoWorks Signals is a strong player. It lists for $229.00 (as of mid-January 2019). This price point is competitive and the Signals gives you stand alone usability, Bluetooth, Wi-Fi, overall high quality and ease of use all in one ThermoWorks package. This remote read is moving to the front of the line as my go-to! Thank you ThermoWorks for giving me the opportunity to put this to the test.  Be sure to check out all the great products over at
