The C84428 is still sitting in the box, because all the information I can find indicates that the La Crosse C84428 can't report to WU. It's even in the FAQ... but has anyone figured out a way to get this unit to report to WU?
Does the C84428 have wifi capabilities? If so, we could reverse engineer whatever protocol it is using.
Does your lacrosse station have the GW1000U to bridge the weather station console to a TCP/IP network? If so, then you can use the weewx-interceptor driver to do what you want.
If you do not have a GW1000U, you could purchase a 20$US SDR USB device to capture the radio traffic between the console and sensors. Use the weewx-sdr driver to feed that into weewx and WU, CWOP, whatever.
