First off, this is a Jayco issue, not Lippert. The OneControl/MyRv system can do many things, but only if manufacturers install the necessary components. For example, tank level monitoring that you refer to requires the tank level module, (most) lighting requires the lighting module. Manufacturers like Jayco get to pick and choose which modules that they install, and that ultimately determines what features you get.
Guessing from what you have described, 1 light, 1 awning, and what you have not mentioned (landing gear, stabilizers, and slides) is that Jayco installed an 8 channel controller, which can control 7 reversible motors (awnings, slides, jacks), and one lighting channel. If you have a wall mounted 5" or 7" screen, chances are that controller is connected via CANBUS to it. For the other awning there may be another Lippert controller, or the awning may simply be wired directly to the switch. There are again, decisions that Jayco made.
You can expand the system. I did and didn't even have a touch screen in my Eagle HT I started. Check out
this thread to see what I've done.
