The Full Review
The Signals is designed for long cooks where you need to monitor multiple pieces of meat simultaneously. I run it on every brisket, pork butt, and turkey cook — one probe in the meat, one on the grate, and two more tracking whatever else is in the smoker.
WiFi connectivity means unlimited range. I get alerts on my phone from anywhere — the grocery store, the gym, bed at 3 AM during an overnight brisket. Bluetooth serves as a backup when WiFi is spotty.
The rechargeable battery lasts 16+ hours, which covers even the longest overnight cooks. The base unit has a clear, readable display showing all four channels simultaneously. Alarm thresholds are set per channel, so you can target 203°F on brisket while alerting at 165°F on chicken.
At $229, it's the most expensive consumer thermometer I've tested. But for anyone doing regular long smokes, it pays for itself in saved meat and sleep.
Who Is It For?
Serious smoker enthusiasts running multi-hour cooks. Competition BBQ teams. Anyone who wants set-it-and-forget-it temperature monitoring with bulletproof connectivity.
Final Verdict
The ThermoWorks Signals is the best multi-channel thermometer available. The $229 price is justified by WiFi connectivity, 4 channels, and ThermoWorks' unmatched accuracy and build quality.
