we also have to call Recalculate_Powered_Entities, and you should mention that we only have to do it on init and config changed

Good point, I've added some more information to the main page. Does that look good?

from what i've seen in your code i think it needs to be done on every configuration changed? i'm not sure..

Oh I thought you meant to tell mod authors to call it. It's quite a heavy action to be honest (the player sees a few second freeze on large factories), so I'm not sure if triggering it on every single configuration changed is a good idea.

I could probably track if a new entity was added and after a small lag run the recalculate though. I'll sit down and take a look at what I can do.

Ok, the new version will trigger a recalculate with a 5 second delay after the last entity is added through the remote call.
