In my breaker box I have combined multiple breakers on one by putting the wire from both breakers through the same CT. This is pretty easy if they are adjacent in the panel on the same side.
Keep in mind they have to be on the same side (black/red) of the panel and going the same direction breaker to load. If on the other side you need to reverse one wire through the CT so they add, and don’t subtract. This can be difficult if you don’t have extra wire. For a 240 V circuit instead of reversing the direction of the wire you can use the other leg of the dual breaker since that in effect reverses the current on a symmetric load.
I have three panels, two with more than 16 breakers, so combining similar circuits still lets me monitor all circuits with one monitor per breaker panel.
Now if there was just a way to combine two primary panels under a virtual “house” panel…
