Every once in a while my pi reboots (power) and so far I haven't had any problems with weewx getting the data from the Ultimeter 2100, after coming up on its own. I just now did a sudo reboot, and now, even after restarting / reloading / (several times) weewx, and removing-replugging the USB, I'm still getting Jun 21 17:05:56 RPI3 weewx[1430]: ultimeter: Failed attempt 5 of 5 to get readings: Une...013 Jun 21 17:05:59 RPI3 weewx[1430]: ultimeter: Max retries (5) exceeded for readings Jun 21 17:05:59 RPI3 weewx[1430]: engine: Caught WeeWxIOError: Max retries ( 5) exceeded...ngs Jun 21 17:05:59 RPI3 weewx[1430]: **** Waiting 60 seconds then retrying...

I'm not sure if the update caused the problem, because often if I reboot the pi, the serial port and the ultimeter.py and the ultimeter just stop giving the right data. Sometimes a reboot does it, sometimes unplugging everything after powering down, the replugging fixes it, sometimes it depends upon the position your teeth are in. I'm seriously hoping you have sage troubleshooting advice I can use to fix this combination. I like Peet's (It is here in Germany at the house we're renting), and my Davis is back home, which works without a single problem for several years. This Peets w/ the serial-USB has been a headache.
