rtl_433 crashes after several days #2551

Closed ifuchs closed 5 months ago

I have been running the following command: rtl_433 -D restart -F "mqtt://192.168.3.136:1883,user=homeassistant,pass=geeCheemoh7uhaiz8uizaisiexahiem0ESoa5leemae8Pheighah1echaht6eic0,retain=1" rtl_433 version nightly-33-gf775d1ac branch master at 202304221552 inputs file rtl_tcp RTL-SDR Use -h for usage help and see https://triq.org/ for documentation.

It invariably crashes after several days and can be restarted without any other action. Why is this crashing and how can I keep it running?

zuckschwerdt commented 1 year ago

libusb error 6 is LIBUSB_ERROR_BUSY. This might indicate that the RTL-SDR dongle is stuck somehow. Perhaps an undervoltage glitch or maybe overtemperature or just bad luck?

fallenpegasus commented 1 year ago

Most SDRs glitch every few days, more often when they get hot. And libusb is brittle. And rtl_433 doesnt try to recover from libusb errrors, because how could it?

I just run my rtl_433 under the control of supervisord.

I've not used supervisord. My RPI0w command is:

rtl_433 -D restart -F "mqtt://192.168.1.115:1883,user=homeassistant,pass=XXX,retain=1";pushover-cli "rtl433 stopped on Pi0W".

This runs rtl_433 and sends me a notification if the command ends. Unfortunately, sometimes it stops working and writes an error message to the console but does not end so I never get a notification. Two questions, if I use supervisord, do I just put this complete command into the .conf file and second, will it be any better at detecting when rtl_433 has ceased working but has not ended?

zuckschwerdt commented 1 year ago

There is a subtle bug when shutting down (the not working) receiver and rtl_433 can get stuck before reaching the -D restart action. I still have to debug that or rewrite the logic :/

S.a. #2426

gdt commented 5 months ago

Referenced bug fixed, and no recent test with up-to-date code. Please feel free to add evidence that there is still a bug and we can reopen.
