There may be two things going on here. 1. Despite having a lot of records that have not been downloaded (513 pages), the final timestamp in the logger memory is *earlier* than the starting timestamp. This is a sign of logger corruption. See the wiki article *Corrupt station memory <https://github.com/weewx/weewx/wiki/Troubleshooting-the-Davis-Vantage-station#corrupt-station-memory>* .
2. But, you are also getting "no <ACK>" messages. From your description, it sounds like you are using a serial-to-usb converter. These are notorious for being unreliable. If you have a second converter, give it a try and see if it does any better. -tk On Mon, Aug 14, 2023 at 11:55 AM Matthias Manhart <matthias.manh...@gmx.net> wrote: > Der Befehl lsusb gibt folgende Angaben: > > Bus 002 Device 002: ID 152d:0578 JMicron Technology Corp. / JMicron USA > Technology Corp.
