I assume there is a battery or two in it that have to be replaced periodically.
Pricey for one probe, but to be expected with WIFI in it.
Do they say how accurate they are?
I just took the flat of a brisket off the grill, point is is still in the grill.
I use the ThermoWorks Smoke.
Had probes of one unit in the point and flat, and a probe from another to monitor grill overnight.
