I have been running WeeWX on a Pi3B+ for quite a while with few problems. I decided to reclaim it for other projects and put my Pi0W in its place. I have the serial logger with Davis cabling to their RJ11/RS-232 adapter which is plugged into a Keyspan USA-19hs serial adapter.
Although I could use [wee_device --current] successfully (and other similar commands), the main program was not successful. Oct 9 15:42:02 pi3 weewx[1707] INFO __main__: retrying...

After far too many hours (7+), I finally decided to revert to the Pi3B+ and was rather surprised to see it working correctly. It appears that others are successful with the Pi Zero W so I'm wondering if someone can help me get mine working.
