hi terry, it would help to see more of the log, in particular the messages that lead up to that 'no such file or directory' message. is the ultimeter connected directly to the pi, or via a hub? what kind of rpi is it? are you plugging/unplugging things into the rpi while the ultimeter is connected? whenever there is a usb reset, the usb-to-serial device may change, e.g., from /dev/ttyUSB0 to /dev/ttyUSB1. it depends on what else is connected to the usb, and it depends on how flaky the usb hub is. the usb 'hub' built in to first-generation rpi is not as reliable as rpi2 or rpi3. the usb on all rpi is sensitive to the type of power supply you use to power the pi. next time you see that error message, do 'ls /dev/ttyUS*'. if this is, in fact, what i happening on your system, you can work around it by using a udev rule to change the device name to /dev/ultimeter, for example. that will not fix the problem, but weewx will be able to recover without your intervention. m -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
