Know before you buy
Yes, Signals functions perfectly as a standalone device. You can monitor all four channels directly on the large, backlit display without needing to pair it with a smartphone or network.
Signals features a built-in rechargeable battery that provides approximately 16 hours of use. For longer cooks, you can also power the unit using the included AC adapter or a USB power source.
Signals uses both Wi-Fi and Bluetooth. When you are within range, Bluetooth provides a direct connection to your device, while Wi-Fi allows you to monitor your cook from anywhere via the cloud-based app or web dashboard.
Signals is IP66 splash-proof, meaning it is designed to withstand light rain and accidental spills. However, it is not fully waterproof, so it should not be submerged or left out in heavy, sustained downpours.
Absolutely. Because the Thermapen ONE is an instant-read thermometer with a one-second response time and high accuracy, it is excellent for checking the doneness of any food, from baked goods to candy or chilled beverages.
