Thaumometer opens vanilla vanilla chests, and you need to shift-right click to scan it, and this is the correct behaviour for storages in my opinion. I’m not sure if mod still updates, but this would be a convenient change. I hope it is possible to do. For example, it works for ironchests mod.
Sorry, but I intentionally made it so the Thaumometer will not transmit Rightclicks to most GT6 Blocks in order to prevent Issues like things not being scannable. This is not going to be changed.
Also why the heck would you wanna hold a Thaumometer if you did not wanna scan it?!
It’s an easy access for items. Drop an item from chest, scan it, then move it back. Switching between quick slot isn’t that convenient.
I guess you will have to use a vanilla chest for it, sorry.
It is traditional that right-click interacts with block and shift+right+click interacts with the held item. ^.^
