I had a brainstorn! Get a wireless security camera and point it at the smoker on the sending unit of a ET-7. Now you have computer access of your temps. This is about as geekey as I get.
if you really want to do this, ditch the oven probes and go with a thermocouple. Go to www.phidgets.com. Buy their USB to thermocouple controller. Go to www.thermoworks.com and buy the best thermocouple you can afford. If you do both of these things, I know a good programmer who would write you a program for free.
