I'm trying to check if my tanks have filled before launching to my next destination, and it seems the "circuit condition" check for a signal doesn't seem to pass, even when the "circuit connection" window indicates that the circuit is connected and the values are certainly present and should satisfy the conditions on the hub. I tried connecting a constant combinator and just feeding in a different signal and checking that signal and that doesn't work either.

Attaching save file.

It looks like I had to check "Send to platform".

I wish this was more clear. I would expect this functionality to be called "read connected circuit network" or something.

I just wanted to say thank you for posting this. I had this exact issue and found your post through a Google search.
