The external sources screen in Dianemo displays all of the external devices you have interfaced to your system in a particular room. Below I've provided a link to a real External Sources screen for a room that is part of one of our demo systems. I've used an image from the Athena HTML5 Orbiter to illustrate this screen but there are equivalent screens in our current Orbiter UI too and they work just the same way (they don't look as cool though!)
See here for the Orbiter screen images; http://www.ellipticalcurve.com/smart-home-software-services/dianemo-athena-html5-ui-screens/
In the first example image (at the url above) you can see 6 rectangular buttons, each of which represent a particular device;
- Denon Internet Radio
- Panasonic DMP-BDT330
- Sky+ HD Digibox1
- Sky+ HD Digibox2
- Sony Blu-Ray
All of these devices are attached to a Denon AVR AV Receiver. By selecting one of the buttons Dianemo will command the Denon to switch inputs to the selected device and the output of the selected device will then be displayed on the TV display that is connected to the Denon's Monitor HDMI output. At the same time all the control commands required to control the selected input device will be routed to it by your Dianemo Nervecentre and the Orbiter screen will change to one designed for controlling the selected device too.
Assuming you selected the 'Sony Blu-Ray' button in the external sources screen you would see the Sony Blu-Ray remote control screen on your Orbiters screen (see the 2nd image at the url above). Selecting sources and controlling them is as easy as that.
All the best
