Please add Inventory Sensor to the group.

If you mean making it so the Inventory Sensor is in the special group for the mod, contact the mod's (Inventory Sensor) owner, Schallfalke said that this is going to be just the framework, that other mods can put "into".

EDIT: quote from the FAQ

Q: Why not this mod just set all the subgroups of all other circuit components mods?
A: It is because I feel it is not the best way to do that, and maybe a bit disrespectful to fellow modders. They may have their preferred way to handle things, like using further subgroups to show things nicely. Furthermore, setting subgroups of their items may actually disrupt and prevent fellow modders to work with this mod.
So I leave this mod purely as a common and basic framework for everyone. No code will be included to directly alter any modded items (not even those from my other circuit components mods!)
Still the best way is for fellow modders to add conditional assignments to their own items, who know their own mods the best.
