it sounds like the rpi zero does not provide sufficient power to its usb. the fine offset stations are notoriously sensitive to usb voltage. the wh23xx driver is dealing with the usb flakiness as-designed. in your case it takes 3 tries to get data when connected directly to a pi zero. you can do a faster polling interval, but less than 48 seconds won't do any good. the all-in-one instrument cluster sends data every 48 seconds, and luminance data every 60 seconds (just like the old ws1080/2080/3080 hardware). i typically use 60 second polling for fine offset stations, with a 300 second archive interval. m -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
