We just added support for Graupner HoTT SUMD protocol. Also, the JETI UDI protocol is the exact same thing as the JR DMSS XBUS Mode B.
So, the X10+ now supports the following protocols:
XPS Xtreme Fast and Slow, Futaba SBUS and SBUS2, JR DMSS Mode A and Mode B, JETI UDI, Graupner HoTT SUMD, and Spektrum satellite (10 bit and 11 bit).
