No wires, no hassles, no guesswork. Bring accuracy and consistency to grilling and rotisserie cooking with the Smart Wireless Probe Plus with Booster and Charger. Simply link the Wi-Fi® booster with the Weber Connect® App on your smartphone to set up your cook, monitor temperatures, get flip and serve alerts, and doneness notifications from anywhere. This thin probe inserts cleanly, leaving only a small hole to help keep juices inside. Four strategically placed sensors inside the probe track the lowest temperature from the outer edge to the center of your food for delicious results. Plus, an ambient sensor at the end of the probe tracks the temperature near your food, so you know when to adjust the heat. Expand your system with the Smart Wireless Probe and Charger (sold separately), available in several colors to make it easy to track multiple items at once.
