How do I control FGRGBW-442 RGBW Controller 2

Add-ons Bindings
131

Is there a chance to add the same feature to FGRGBW-441 (the first version of Fibaro RGBW Controller)?
I believe it’s all about database, but probably I’m not the one who can do anything there.

Edit:
I just did it in a stupid way:

  1. got the org.openhab.binding.zwave-4.0.0.jar out of repository
  2. using 7-zip browse to *OH-INF\thing\fibaro* and edit file fgrgbw_0_0.xml adding:
<channel id="color_raw1" typeId="color_raw">
    <label>Color Raw</label>
    <properties>
        <property name="binding:*:StringType">COMMAND_CLASS_SWITCH_COLOR</property>
    </properties>
</channel>
  1. upload changed .jar file to /usr/share/openhab/addons directory
  2. remove and install again z-wave binding (not sure if necessary)
  3. remove item and add it back using jar:binding-zwave (not sure if makes difference, but the original binding is still there and has no jar: at the beginning)
  4. profit!

Can anyone do this the right way?
