Adding new device support to RFXCom binding (Doorbell)

Hi all, First post so please be gentle…

Currently running OpenHab2 on Linux server and I’m missing support for a door bell.

RFXMngr is showing the below when the door bell is pressed:
Packettype = Chime
subtype = SelectPlus
Sequence nbr = 36
ID = 030059
Signal level = 7 -64dBm

In OH2 logs using DEBUG I’m seeing we following:
2017-05-01 14:11:46.016 [DEBUG] [g.rfxcom.handler.RFXComBridgeHandler] - Message not supported, data: 0716021800175970

I was wondering if anyone can help with adding support into OH2. I did come across an old posting regarding adding SelectPlus but as yet I have not been to add the doorbell as an item manually in Paper UI.

I’m also not sure if I can also trigger the bell separately on a given trigger or even better a different sound, on say one of my cameras detecting motion using ZoneMinder binding which is working very well.

Any help much appreciated…
