I'm trying to use the level emitter to disconnect a portion of my ME system if the system energy level drops below 6,000,000 RF. However, I notice that ME systems can display power in a variety of units, such as AE, EU, and RF. Which one is used when inputting the number into the level emitter? I've messed around with it for a while, and no matter what I do it doesn't emit a signal, and sometimes WAILA says "device lacking channel" even though clicking with the Network Tool shows it on the list, and I know there's a channel open for it. What's going on?
