LightwaveRF Dimmers

So I posted here before about lightwavrf dimmers but had to give up trying to configure Homekit as didn't have enough time.

I have now purchased the Plug-In and it is up and running in basic format and I can turn lights on/off etc.

I still have the problem of not being able to Dim any LightwaveRF device.

I suspect this is because the option in the device does not have "Is Dimmable" ticked, which it can't be as it is greyed out.

Has anyone else managed to configure lightwaverf dimmers to work?

In the previous thread I was told to select Lightbulb Service and then On/Off/Dim, this doesn't exist. See attached images
