Detecting if a Machine is Running

[nardavin]

What I want to do is make an Applied Energistics setup where it can tell you if a certain machine is currently processing items (such as lighting up a lamp), but I cannot figure out how to detect it for non-buildcraft machines. The way I did it for the buildcraft machines was detecting if there was space for energy. (not the best way, but it was the only one I could figure out) It does not give me that option for non-buildcraft machines. Does anyone have any solutions to my problem?

Details:
-I am using Ultimate
-Other machines include RP's bluelectric alloy furnace and almost all of the IC2/Gregtech machines.

Checking if there is items in invotry might work on some. BC pipe gates can do that.

I tried that, but it doesn't detect properly. However, when I tried, the pipe was also connecting to some AE wire, could that have affected it?

For GT machines you can use covers that emit redstone signal upon machine activation

Ok, thanks.
