The Beo4 does not control any non-Beo products.
Your TV might control non-Beo product with a PUC or a STB-C.
The list of devices is available in the menus.
The Beo5 will control non-Beo products, but it seems more targetted to non-AV products, like curtains, etc...
The official solution for controlling non Beo AV products is the PUC or STB-C in your TV.
When people have received their Beo5 we may know more. I wouldn't order one before being sure it can do what you want.
