I *finally* got a response from UDI on that thread. And the entirety of it was " If you are not happy with ISY, UDI, or how we run our business no one is forcing you to use either. "
If I have to go back to SmartThings replicating to VRCOP I may very well throw up in my mouth. I hate how Leviton has treated zWave controllers.
I was all set to move functionality from CQC to Elk & ISY in 2015, and only use CQC for optional or non-native control bits. I now find myself going the other way, and centralizing into CQC. Esp since low power Windows Embedded units are <$200 (I have one running W10 for an RDP viewer plus a Cryptocurrency proof-of-stake, works remarkably well).
This is a crappy situation. I really wanted ISY to win but that required a 2015 release of 5.x, then upgrading that awful java-based GUI which is now all but unreadable on modern laptops. Font size is tiny, even when you up it to 20 point.
If I hadn't spent $500 on an ISY plus Elk module plus portal, this wouldn't be so difficult.
