I was able to get MRV activated in unsupported mode on day one. I had always planned to go DECA, but I didn't want to lose MRV. Last night I finished up installing what turned out to be a SWM16 and 6 DECA adapters. Now that I am running the approved config, is there any way to get back on the supported side of the aisle. Now before anyone wonders why I just didn't let D* do it in the first place, it took me almost 2 hours figuring which lines went to which receiver (all DVR's had 2 lines), another 1.5 hours installing a DECA on a receiver in a custom cabinet, and another misc hour or so for other stuff. And as a DIY'er, I am pretty good at this. So any installer who showed up at my house, was going to have a job on his hands. And since they get paid per job, he may have been below MW after he left here. Plus, I like doing it myself.
