MrWorf Posted July 8, 2013 Posted July 8, 2013 I don't know if this has already been solved, but today I installed a bunch of dimmers and my goal was to make the bedroom light somewhat smarter. My setup consists of 3 dimmers all linked together as a scene on the ISY994. This works fine. But now I wanted to spice things up by having the ISY change the dim level from 100% to 10% after 10pm. Easy, just "Adjust Scene" and set the load for the scene... Erhm, right. After digging around and tearing at my hair, I finally solved it by setting the "scene" on-load for the load dimmer to 10% and then every individual dimmer would also be tweaked to 10% for both itself and the load dimmer it was controlling (at least, that's what I had to do, let me know if there is an easier way). But this only half the solution. By setting the dimmer to 10% I get the benefit of having the second "on" tap to go 100%. But this is where it got tricky. This second "on" tap didn't work on any other dimmer than the one controlling the actual load. The other ones just sat there. The solution is to have an additional program (actually, one for each un-loaded dimmer) which monitors for change and then fakes it. Basically it issues a 100% level change to the load dimmer while simultaneously applying 100% locally AND to any other un-loaded dimmer (that's important, don't miss it). Now, any dimmer will go to the initial 10% and a second tap, on any of them will go to 100% and finally the third tap (again, on any) will bring it back down to 10%. Off works as expected. I've attached screenshots from the ISY Admin of the programs. Hope this helps someone in the same situ as me
bsobel Posted July 27, 2013 Posted July 27, 2013 "This second "on" tap didn't work on any other dimmer than the one controlling the actual load. The other ones just sat there." Are all of the dimmers controllers for the scene? This should just work, I'm not why you had to glue it together with a program to monitor them.
MrWorf Posted September 25, 2013 Author Posted September 25, 2013 Sorry for my late reply. Didn't get a notification for some reason. Anyhow, yes, all three dimmers are controller/responders for my bedroom scene. The code is to make sure the others are able to make the loaded dimmer go to 100% or 10% (as the case may be). I have seen issues that the indicator light on the dimmers sometimes show the wrong state (indicating 10% when it's actuall 100%) but the functionality as such has always worked. I don't know how I would make it do the 10/100 setting without programming it. If anyone knows, please enlighten us
