Does anyone know what this piece of kit is? 

I am going to buy a Beovsion 9 and already have a Lutron lighting control and would like to use the Cinema function to dim the lights and maybe illuminate my Beolab 5's like Beoliving!

Is the "Home Automation Sytem" made by B&O or is it a third party product.

Any pointers would be welcome.

are you talking about the Beoliving concept? as far as I know, it includes B&O products as well as non-B&O products. you can control stores via the remote, dim the lights, even if you have another light controller than LC2... I'm sure your dealer can help you...
