I have been having a problem for a couple months. WD goes offline randomly. I don’t know if it is WD or my Davis Vantage Pro02 Plus weather station. I just don’t know what to do. Has anyone had this problem? Attached is is screen capture from today.
I’m on Windows 10, Davis Vantage Pro2 and WD 10.37S Build 120.
If it is the scenario where only some sensors, looks to be your wind speed and wind direction, flatlines but WD remains working where all other sensors are reading correctly, then yes I had this quite a long time ago. When I had this issue it wasn’t WD, i.e. its still recording the other sensors. I seem to recall it was a problem I only had with the WeatherLink USB interface, not serial which I use most the time, and, my (poor) memory kind of recalls the problem with an old version of the Silicon Labs USB driver - possibly the memory leak issue with that driver.
Therefore check in your Device Manager that you have the latest USB driver. Hope that helps.
Maybe need a new battery, looks like outdoor sensors dead at night while indoor sensors are ok. Just guessing, hard to read the screen shot you posted…
