Another, perhaps simpler, approach just occurred to me. On the snow depth
RPi run apache with php and have a function that returns the snow depth
value upon a web request. On the weewx machine, write a custom service
that makes the web request, parses the returned value and stores it. Then
I could use all the suggestions in the documentation for a 2nd data
source. I'd just have to anticipate error conditions and figure out how to
deal with them.
