The OT7 is a slick product. For maybe 80% of users, it's pretty and it does the basic stuff well while looking good doing so. The trouble is, for the remaining 20% who want what it's really capable of, or at the least want the OT7 to not REMOVE functionality that existed in the 5.7, it's very frustrating.
The 1.6 release addressed the obvious "broken" stuff - namely that the security interface now works (critical for a system that is security at heart, and to not have to explain to homeowners why they can't use their slick touchscreens to control their security system), and that the basic functionality of lighting and audio control.
To me, now that the basic functions work, I feel better about the OT7 but it's still annoying to not have the things that the 5.7 had. Nobody wants a new product that is a DOWNGRADE from their old product in feature set.
I have to agree that @rhombixt hit the heart of the issue though - lack of passion. I was excited to learn of Leviton's acquisition at first because I thought it added a great capital and distribution base to build the HAI product line. Whether that is happening or not is unfortunately obfuscated by the corporate opacity that is all-too-common with larger enterprises. I miss the days when you could call HAI and they were passionate about their product and could address your concerns. Now when you call, it's either that you talk to a corporate drone who doesn't know anything, or doesn't give a hoot to share it if they did. The former is an organizational problem; the latter is tricky because while I understand the need to keep some secrets to maintain pace in a competitive market, the cone of silence just makes the dealers and users mad.
Give us a development timeline. You knew you went to market with a decontented product that didn't do half of the predecessor product it "replaces" - surely you have a plan to give those features back... Don't you?? Share some information so we can continue to promote and support your product in the field, or else we'll sell and install a product that doesn't leave us exposed in front of our customers!
The lack of passion concerns me greatly. My biggest fear is that Leviton bought HAI to bury it.
