For what it's worth the rain sensor is a plastic tipping bucket type
with a magnet embedded in the bucket plastic.  This goes past a reed
switch as it tips in each direction.

So what you really have are switch closures being read by the
processor in the outside temp/baro/humidity sensor housing.
Unfortunately you have a nice HF antenna connecting the two.
