All I can suggest is that if you can swap in a different pi/SD/power-supply and it goes away, that would point to the pi3 being the problem. If the problem continues with a different computer, that would point to your datalogger probably.
Your logger will save a week of readings, so there's little risk of losing readings if you swap in a different pi temporarily for a couple days. You didn't answer Tom's question - is it a Davis USB logger, or a serial logger and serial2usb adaptor ? -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
