Where do you get the 12 v pwm's from? How much do they cost approximately?
Rule #1 - Be Patient - Rule #2 - Don't ask when, if you don't contribute - Rule #3 - You have coding skills - LinuxMCE's small brother is available: http://www.agocontrol.com

If it is too much work for you to properly quote your replies, it is too much work for me to answer them.
Because one is wasting energy and other resources using a gazillion little transformers. At least I do not know of any LED that works at 230V without a transformer.
I use them to turn on/off lights in hallways (and soon guest toilet). I am also using them in a dual purpose room, which is both hallway and play room for the kids. Unfortunately, even PIRs are not detecting non-movable people. I planned on using them in other rooms as well, but won't due to them only working when motion is detected, and not presence.Some manufacturers suggest that their PIR's will act on a person typing on a computer. I haven't seen it myself, but you mean
QuoteThe MDT stuff should work. Get one, with return guarantee, and test it. I personally don't like 230V LED stuff.How come you don't like 230v LED stuff?
Same here. I have MDT and like them. You can control several blinds with one output, but you need a relais in between. In the end, I decided to control every blind individually, but group them with LinuxMCE. However, I would not try to control a motorized projector screen with a blind actuator, as the blind actuator is not exact enough.QuoteI have KNX PIRs as you are able to get more than motion, but also light intensity setup automatically. Apart from that, if you really want 1/0 only, binary inputs are neat. Some binary inputs only have problems with accepting higher frequency inputs. So if you have stuff that changes rapidly, and you want to count that, make sure your binary input supports it.How do you use your PIR's? For motion detection to light up all different kinds of rooms. Or just toilets, attic, closets?
Do you believe fully automated motion detected lighting control when entering and leaving a room is something worth trying. I've been advised not to use it that way before. Only for closets and toilets and use push-buttons for other spaces.QuoteApart from that, one word of advise, IF you have a significant other: Make sure your install works without LinuxMCE. It is okay, that timed events don't fire without LinuxMCE, but not being able to turn lights on/off, or opening/closing blinds without LinuxMCE running, is a recipe for trouble in the relationship.Good advise! Thank you! Does that apply for network running automation too? Telldus have their Tellstick NET that runs directly from the network without need of server. Would you consider that too much of a functionality risk too?
MDT has 8-fold sensors http://www.eibhandel.de/MDT-BE-TA550801-Taster-8-fach for 80EUR (as a special it seems)
or the http://www.eibhandel.de/MDT-BE-0400101-Tasterinterface-4-fach for 60EUR
I think you have to provide your own roms.
