Computers will not interact with blocks such as tanks and batteries. Less of an issue more of a feature request.

On Fabric the Energy and Fluid generic CCTweaked APIs are missing (See cc-tweaked/CC-Tweaked#1822). I will not fix this myself, but you could try out this mod: https://modrinth.com/mod/unlimitedperipheralworks

But I'm currently working on EnergizedPower specific CCTweaked integrations for Redstone Mode, Comparator Mode, Time controller, and Weather controller interactions
