Of course, an ISY-99u would solve many of these problems, but I believe it was on the UDI web-site that I saw that they are no longer planning on making a UPB version, Anybody know why they made that decision
I can't say with 100% certainty why plans for a UPB ISY were shelved, but I believe it was primarily a ROI decision.
That's unfortunate. I can understand that UDI has a lot of time and money invested via Insteon, so I hope the decision wasn't based on a fear that they would be cannibalizing their own product. I could see a use for having both products. Insteon and UPB each have unique and appealing properties as well as frustrating limitations. Many of the limitations of Insteon are mitigated by the ISY99. Having an ISY for each (or even better a hybrid ISY that could control both) would allow a person to mix and match UPB and Insteon instead of having to choose one or the other.
In my situation, a couple years ago, to test each system I installed UPB in the North half of the house and Insteon in the South half. I like them both and am frustrated with both. I really don't want to have to choose one or the other.
