Well known to people that look into the IDE and follow the developer conference calls. I just found a discussion where this was actually addressed in early September as you said, but there is no actual reply from anyone in the ST team.
I did found this post by ST CEO from September 5, 2015. Still waiting on that growing list.
As a user coming from the Wink hub, another big reason to get the V2 hub was because it actually supported the devices I already had on the WInk hub. So, changing all those devices to official ST device types is not feasible for now. I do not want to spend the money on every single contact, motion sensor and some of my wall switches just now.
Don’t get me wrong, Mike. I like the community and appreciate all the help I get from it and I try to give back whenever I can, but I always go to an official product FAQ first than to a community because it is easier to get the information I’m looking for.
