You got the corporate response. Everything I have stated above is true and accurate. If you do not want to try it, get a SAI remote and do it that way.
As to Incompatibility between manufacturers of UPB products; it is interesting that it is often the case that when a problem or concern is posted on one of these forums, that many people post "that's happened to me" or "I have had a similar problem." This happens a lot with a certain other "New" protocol; you see it by the large number of threads.
I noticed that no one else has posted on this thread any incompatibility problems with cross utilization of manufacturers of UPB products. I'm sure there must be some out there?????
I have used PCS and SAI products mixed with no problems. I have heard similar statements from others that have used HAI with SAI. It is nice to install a switch (any manufacturer) and have Upstart see it, program it, and "It just works." I know that a lot of work goes into keeping Upstart current with the new products and new features that each of the manufacturers require.
We all should be thanking ourselves for sellecting this protocol instead of Ins.....
and that our problems have been tiny compaired to those poor folks over there.
