LED PWM dimmer automation hookup

[activemind]

I installed LED undercabinet lighting in the kitchen and used an off the shelf PWM dimmer. Everything is working fine. Now I want to somehow connect this to my automation setup (when I have one...ELK with ISY)...
 
What are my options?
 
Google doesnt return much. I have looked at CAI webcontrol with a relay but what about dimmer?
 
I plan to put proximity sensors in the kitchen in future and would like to tie it with the dimmer. Basically, the lights are dim when its dark and no one is in proximity and glow to 100% brightness when they detect someone.
 
I want a generic solution so that I can replicate this at a lot of places (deck, walk-in-closet etc)...
 
Suggestion? What have people done for this!
 
Thanks

LED driver with 0-10V input for dimming control or DMX or other newer digital control network interface.
 
That should give you a lead to something - I am not in the US so recomending something is pointless - best I can do is guide you.

Just the DMX controller is like a grand in cost h34r:
 
DMX Controller
 
Wouldnt an Aurdino with a PWM shield be a cheaper solution! I havent put together all the pieces but I am guessing it could work!

0-10V is older and should be cheaper - just not sure on how you would drive it (Audrino analog output).
 
No idea on the Audrino

Use arduino or raspberry pi to generate the DMX control signal.

or use an IR controlled dimmer and something to generate the IR signals.

Did some more research and I think I will go with arduino solution rather than DMX (proprietary). I found a LED shield that will do PWM support but havent found anything yet that would do close to 2A current at 12V, this one does a max of 1A. Also network connection would be an issue. I am not sure if ethernet shield is stackable  or not.
 
Anyways, I placed an order of Arduino, network shield, LED shield, PIR sensor. I will breadboard everything and see if I can make it work.
 
The best solution would be a 2-4 channel 2A shield with network on it...if such a shield exists!

DMX is not really proprietary. There is an Arduino DMX shield. The advantage is that you can hook up a ton of DMX dimmers to just one arduino.
