"What happens if you 'pull the plug' on your VP2? Does it keep running? Perhaps the batteries are bad?
Yes, it keeps running, that is why it seems to be a weewx issue to me. In other words, if the Pi Zero running weewx were not connected to the VP2, the data logger memory would not get corrupted. In fact, weewx is able to recover data that was gathered during the power outage (while the Pi is shut down). It is only when power is *restored *that the data logger corruption happens. At least I assume that is really the root of the issue, I really don't know. All I know is that almost every time the power goes out, I get the record time error and all data recording and uploading stops. I've looked into getting a UPS for the Pi, which really appears to be nothing more than a $15 ext phone battery, but it seems to me this is a weewx problem that should be addressed. Alternately, I can contact Davis to see what they say.
