I just set up a Meteobridge for my Oregon Scientific WMR968 (don't laugh; I know it's ancient). The data shows correctly on the Live Data screen so I know it's getting to the TL-MR3020, but Wunderground and PWS Weather show -- for the temp. I'm using a non-powered USB hub.
I wonder if this is the problem - I'm using the unit on channel 3 to transmit temp and humidity.
Any ideas?
Thanks,
Robert
