Been an iGrill user for years, decided it was time for an upgrade and moved to the Grilling hub.  Love the WiFi connection and range.  Disappointed in the battery storage.  Plugged it in, full charged it, unplugged from the power, and placed it in a cabinet for the next grilling.  About 2 weeks later took it out, plugged in the probes, nothing!  Plugged it back in charged it up, put it away again.  About a week later, took it out to use, again no battery,  I guess I will need to leave it plugged in all the time.  One of the probes stopped recording, no obvious breaks in the wires or damage.  Time to buy a replacement,
