I think this can help you:
You can use Cobblestone Pipe Structure with Basic Gate and Red Pipe Wire, like this in the pictures
obs: I have Low Energy Stored
How you see in the image Basic Gate is sending a Red Pipe Signal On to the other Basic Gate and when this Basic Gate receives it sends an Redstone Signal that activates the Piston but this only happens when it is set Low Energy Stored because my Energy Core is with low energy but the case is set for High energy Stored the Piston is not activated because my Core Energy is low on energy.
I hope this helps but if you do not understand I explain further
