I am getting a periods of about and hour randomly where I get flat lines in WD. Also even with Solar and UV ticked I’m not getting solar.
Just running a Davis Vantage Pro 2 with USB datalogger straight in to my PC. Have tried other USB ports, confirmed they aren’t in low power mode and turning off like another post suggested. and set up a daily reboot but still happening.
re the solar, I do see you have a solar value showing , above the windspeed
re the flat line, one thing, is to did you check the selective suspend in windows for usb power setting as well?
( I have a youtube video on how to check/set that)
