It is a cloud connected thermometer that can track data via WiFi and Bluetooth. It also works with Amazon Alexa and Google Home. It has a LCD screen to show data from all probe ports at once.
The FireBoard 2 is compatible with thermistor or RTD probes. It can monitor up to 6 probe channels at once. The pro version offers even more precise temperature tracking for food and commercial applications. The kit ships with an ambient probe, 2 food probes, grill clip, and everything you need to get started.[where to find it]
