Understand this is only for Vera 2. Not Vera 1. I just updated the wiki to be sure this is clear:
When you say "only for Vera2", do you mean "only for Vera2 when using its internal Z-Wave chip"? Recall that some of us are using a Vera2 with an external USB Z-Wave dongle*, and it isn't at all clear whether this configuration is upgradeable to 3.20 yet or not.
(This is largely academic; Z-Wave devices are far too expensive here for me to own more than a few of them, and my puny 5-device network has no issues, so I'm not going to deliberately break things.)
Upgrade to 1.1.1245 was seamless, to get this post back on topic.
* Not by choice, I might add. This configuration is the only one that is available in markets that use the 919.82 MHz and 921.42 MHz frequencies.
