Olive Branch...
123 you have done outstanding things with Premise and brought new life and vigor to a platform that at the time was and still is in some respects light years ahead of its time; my comment was not intended as a slam nor a redirect in any way shape or form on the product. I have a great deal of respect for the vision of that development team, it was a master stroke of software architectural genius. Mater of fact I've owned and used Premise for years and years, I started with it back in the day when you had to pay top $$$ for the license. I purchased just after the Motorola acquisition. Sadly Motorola bought Premise for the intellectual property and the people talent not the product itself, hence today's situation, we now have a beautiful orphan.
I never did get the DSC interface working with Premise, not Premise's failure, ultimately it was a time/value choice that I made. Just discovered CQC, bought into the solution it provides. CQC does not support DSC alarm systems either, in their forums they have clearly stated they will not as a developer, that's fine, there are a million and one devices out there to support, the DSC Alarm happens to be what I have on my home, too expensive to replace, it works reliably.
My story, not yours, not Graham's. It looks like he is interested in making his DSC alarm work with Premise because it is what he has and that is what he wants to do, that's cool. Since it appears that his DSC hardware is already in place the relevance of the comments is in sharing alternative solutions that are already developed and working or a potential future state option (me for my new platform choice which I am just stupidly giddy about at the moment - really it's to change everything so that it drives my wife and kids crazy, nah.)
Bottom line Premise is a great software tool deserving of attention, as are each of the other options out there; at the end of the day I believe we are all interested in celebrating the accomplishment of making the technologies we love (old and new, I still use X-10 extensively with success, now that's old) dance to our form of music the way we want to. Taking really complex things, putting even more complex wrappers around them so that when it is all said and done it's highly reliable and easy to use. And we have fun, mostly, making it so, yes?
