There is a dimmer from Lutron. It's called Rania, and it's easy to install. But it only can be controlled with the Beo5, not with the Beo4, and it can't be labeled with a number, so, if you have 2 in the same range, both will respond to a Beo5 command.
Keith explained it some time ago.
Well, I have two Rania dimmers on my bathroom outside the door as below and have created an XML file to control them

These
Rania dimmers have a remote control BUT are NOT B&O compatible.
With the created XML file you can set 4 different scenes, raise and
lower the light level and switch on and off. The display is below

You can download the XML configuration file HERE
It
is in a zip file and extract it to C:\ if your Beo5 Configuration tool
is in C:\Program Files as the default for installing version 1.30 was
C:\ unlike the previous versions.
