I am trying to work out the format for reading a dataref value from XPlane into my Streamdeck. The dataref is sim/cockpit2/electrical/panel_brightness_ratio and the index is 2. If i put sim/cockpit2/electrical/panel_brightness_ratio[2] it doesn't seem to work. I also tried sim/cockpit2/electrical/panel_brightness_ratio, 2

Thanks!

Sorry, no idea. Should be "sim/cockpit2/electrical/panel_brightness_ratio[n]" 

What aircraft are you doing that with? Are you sure about the index? Did you try the Dataref observer in AAO, can you see the value there (Scripting->Watch datarefs)?

Seems to work fine for me. 

My test went like this:

1. I loaded the default 737 in XP, this seems to use the same datarefs
2. Then I entered the individual datarefs of this array into the observer like this:
   (DREF:sim/cockpit2/electrical/panel_brightness_ratio[n])
   n going from 0 to 3
   Result: they all show values (0.008000)
3. Now I changed the Main Panel brightness
   Result: the value changed accoringly in the observer
4. On the StreamDeck I created a TextGauge
5. For Variable 1 I chose "DREF" and entered this into the box:
   sim/cockpit2/electrical/panel_brightness_ratio[0]
   Result: the TextGauge action shows the value of the Dataref.
6. I repeated the test for indexes 1,2,3 - they all worked correctly.

Many thanks for the quick and thorough response. Have got it working now using your format.
