No, but I'm going to reach back out to them.
The coming version of Roastmaster (due in November) is completely retooled, and will feature an open source protocol for Ethernet communication. This will allow a lot things to be done with lots of different hardware (DIY and other types).
I'm interested in 1) letting manufacturers know this exists, and 2) keeping up with new crops of smarter roasters.
I'll post back here if they bite this time.
