I'm not sure I got the quoting correct here but:
This is the very nature of insteon and X-10. The ISY does not solve that problem, though it can trigger X-10 commands from insteon.
Yes. Nothing is lost.
No. Being in scenes is not necessary for this to happen. But...yes, ISY can handle that.
I am unsure. I suppose it depends on how the palm pad remote interfaces with your system. If IR, then almost certainly this would be no problem. If X-10 RF, then no problem. If something else, .... probably, but would have to confirm.
It is not needed, but I find it useful. It adds no functional capability. Rather, it makes managing your X-10 devices more intuitive by allowing one to give them names and add them to the device listing.
So, where do I see a description of it and how would I get it?
Thank you for the fast response!
