OK, it’s an old page that hasn’t been touched since April 2010, but here:
http://wiki.micasaverde.com/index.php/LuaUPnP#Compound_devices
it says:
[b]Compound devices[/b]We are creating a visual web page within Vera to merge actions from different devices into one device. For example, let’s say you have a PVR, a TV and a Receiver. All 3 will be exposed as UPnP devices. So with the UPnP control point you can pick the PVR as the device you want to control, and you’ll see the actions the PVR supports. However, even though you’re controlling the PVR, you’ll probably also want to be able to control the volume, on, off, and input select on the receiver, as well as the on, off and maybe brightness on the TV. So in Vera’s devices page we’re adding a “Compound” button that shows you the actions for the PVR, lets you uncheck any actions you don’t want to see on the control point, and lets you add other commands from other devices, like the on/off from the TV, so that when the control point shows the actions of the PVR, it will include the on/off for the tv, and volume for receiver, etc.
This seems like a GOOD IDEA. I assume it was never implemented. Does anyone have any more information or ideas about this? Or does some other functionality that I’ve missed completely simply make this obsolete? Having written some different A/V component plugins, I’m feeling the need for some sort of ‘Virtual Universal Remote’, and this idea would seem to come close.
