I have weewx running on an RPi currently. Due to location issues I need to
have a 2nd RPi which will retrieve, process, and store the snow depth
data. Both machines will be on the same local network via wifi.
An alternative that came to mind was to install weewx on the 2nd RPi, add
snowDepth to the schema, run that instance of weewx in simulator mode, and
write a new service that grabs the snow depth data and stores it. I did
something similar ages ago using one of the many unused parameters in the
existing schema.
