Hi, My station has been running weewx + rt_sdr for a year and all is working well. Weewx receives the station data and broadcasts it to windguru. However, there is an occasional problem that happens and i can't figure out what the cause is. All of a sudden, rtl_433 stops receiving from the sensor for hours at a time.
During those periods, when i run: *sudo tail -f /var/log/weewx.log* All i see is: *user.sdr: lines=[]* If you leave it, it eventually comes back online itself. I can confirm that during that time there was no loss of power or internet - because i can still connect to the pi and manage it. Also, weather station has new batteries, so that is not the problem. I have a feeling that the problem is happening with the realtek SDR dongle. Because a power reset sometimes fixes the problem - and a physical removal of the USB dongle into a different USB port seems to fix the problem immedaitely. I've even tried a python script to eject the USB device which also seems to help. But in order to do this i first need to disable rtl_433 in the weewx.conf, then reboot, then run rtl_433 on its own until it sees the sensor, then re-enable rtl_433 in weewx.conf and reboot. That is usually the process to fix it immediately, so it definitely feels to me like a software issue. Any ideas?
