I am working on a solution for logging more roast details with Artisan, and once I have the solution worked out with physical inputs via USB, I will make it wireless with Raspberry Pi and build everything into a box mounted to my control panel. So far I have thermocouples for BT and ET, and differential pressure transmitters on my gas and air pressure. Currently I am working with the author of Artisan to get the DAQ1400 supported. fz
Unfortunately, I cannot speak to Roastmaster. Having roast monitoring on an iPad sound great, but I find that I really don't need anything that encourages me to walk away from the roaster.
