For that money I would expect at least a computer interface or a little
screen, and some software to set temperature profiles. Added GPS
capability to compensate for height above sea level might be left as an
option.

Not a bad idea though, but not if I had to pay money for it. Making one
up from a salvaged PLC and an old temperature sensor is definitely an
option for when the next shipment of round tuits arrives.
