Jason, both switches work independent of each other
Then if one of the two wires together on the original switch runs from that switch to the other in the gang box, the other wire is likely line and you have line and load reversed.
Again, you will want to meter it all out, but if the description so far is accurate, that’s the only physical way they would work independently.

If that’s the case, then he most likely fried the micro, and its no good now.
Were you able to meter the wires and verify which was line voltage? Any luck getting the microswitch working?
I have not had a chance to do it yet. Hoping to do it this weekend.
