Found this while testing the NPE problem finally got round to testing in SP with latest versions of both, Hwyla is showing forge energy info for all conduits (Item, fluid, redstone)

Possibly to do with them registering conduits in world as BlockConduitBundle

Hwyla : B12 (also happens with B11/B9 and I assume more)
EnderIO: 126
EnderCore: 58

I only display the energy tooltip if the Block's TE returns true for hasCapability(CapabilityEnergy.ENERGY, null). If EnderIO is returning true for all conduits, regardless of whether they store energy or not, this would be an EnderIO bug.

E: EnderIO is showing itself to have all sorts of issues with how they use capabilities...

Fair enough suspected it was their end, Minor though so that's something.
