Fibaro RGBW controller and those sensor contacts

I just pulled the trigger on one of these Fibaro RGBWs, which is supported by Indigo and all, which is great.

But I notice this in the description:

Fibaro RGBW Controller has four analog inputs supporting any sensors, e.g. lightsensors, wind sensors, pressure sensors and potentiometers operating within 0-10V range.

Can someone who knows point me at the proper kinds of sensors that I might want to connect to this?

As simple as things like this? Or this?

Also:
Four output channels allow for connecting and independently controlling each of connected light sources.

Does that mean I could theoretically control four separate LED strips with this controller?

Four single colours, potentially yes. It's designed for red green blue and white or any combination.

I have mine controlling four separate rgbw sets of leds. Just check the spec and don't exceed the limits of the device.

Is there really no one who has tried to use the sensor contacts on these?
