Indeed. That's exactly what started me down this route in fact. I had
to find a way to configure the components to generate their own h/b.
Luckily I have an object that manages that, given a heartbeat message,
but I quickly realised I had to alter the UID somewhere.

And in fact that was what made me think to alter the subaddress node,
to indicate they were all packaged together.

Something I wanted was the main UI container application to be able to
set the component UIDs, hence the auto-incrementing of the subaddress
node value for each plugin component.

I may have to come up with some mechanism such that the installer can
configure the plugin component DeviceIDs.

So your UIDs look like "FFFFxx00" ???
