Serve up delicious food by knowing when to raise or lower the temperature of your grill with the Grate and Grill Sensor. Since temperatures inside your grill can vary by several degrees, this ambient sensor lets you monitor the temperature closest to your food with fast, accurate results. Simply clip the sensor onto the grates and plug it into your Weber smart grill or smart hub. Pair with your smartphone and the Weber Connect app to set your desired minimum and maximum temperatures to receive alerts when you need to adjust the heat or add more fuel.
