You just need a 12v or 24v dc PSU (Depentant upon LED voltage - I use 12vdc)
This powers both the Fibaro and the LEDs
On the output of the Fibaro you have connections for the four colours and the return.
really easy to connect and there are a couple of DTH to control the Fibaro.
I use an couple of apps I wrote to change colours on the LEDs
The Fibaro also has a couple of pre-programmed sequences which you can trigger - quite cool.
