removing items from "All Lights", protect from being switched off.

i have the “Lights On” item in the dashboard that shows the currently switched on lights, but some of my items are classified as lights via the RFXcom plugin and show up as “On” but i don’t want them to show up and even be protected from being switched off at all if possible, i tried changing the Device Category from “http://wiki.micasaverde.com/index.php/Luup_UPNP_Files#Device_Categories” but they still show up

can i remove them or even stop them being switched off at all, One is a baby monitor that should never be switched off, but i still wish to see them in the device.
