I have been also interested in having a real time display of the information sent by the station. I use node-RED on the Raspberry Pi to handle that. It's probably easier in my configuration, as I receive the data from RFXcom and generate a file with the data. Weewx upload this file via fileparse, and node-RED reads that same file every time it is updated.
