Hello Tom Apparently that doesn't work for me. I did the following test. At 2:30 p.m., the Raspi took the network away and restarted it. It starts up and then sets its time for the Vantage console, which was around 30 minutes before, i.e. 2:00 p.m. This of course also makes the data in the data logger unusable, since when the Raspi has the network and restarts, the console also sets the current time again. Maybe there is a problem with my weewx file because it still sets the time anew, even though it is in the past?
