True value is added based on some background checks factors as well. As I'm continuously updating this list based on direct interactions we have at customer care team as well. So I'm not relying only on forum input, for an extra layer of confirmation.
UI7 firmware has only one head build and will be exactly the same on all Vera hardware. So if there's an incompatibility with one unit, it will be for all.
Latest available official release is the norm, and Known to work is based on this firmware.
If a new firmware release will break compatibility with a certain device in this list I will surely update it accordingly until this is fixed.
In regards to the "Secure/Unsecure mode" I don't really want to argue about this as I'm not R&D to decide if it's s good feature or not and in what aspect it affects and how many users.
However, I remember, from the training sessions we had with Sigma, that according to Z-wave certification guide lines, the z-wave chip, and gateway software, will detect if the device you want to pair is a security enabled or not and will pair it in accordingly.
The end user ability to choose this would be more useful for legacy users that have old hardware, I believe.
Z-Wave S2 framework will most likely remove this ability all together, leaving this decision in the hands of the Z-wave chip itself.http://www.soundandvision.com/content/z-wave-alliance-fortifies-smart-home-security#l41pmBvKiDWbite0.97
Thank your for the exact models.
