HomeAssistant Core crashing at random intervals, following I/O Error 5 [cannot open serial port] #2

Closed fss closed 3 years ago

fss commented 3 years ago

I'm getting HA Core freezes occasionally, it's still not 100% confirmed but my blind guess is Selve connector unfortunately. Every single time my HA crashes I'm first seeing I/O Error 5 [cannot open serial port] followed by a MQTT client error and then my HA core becomes completely unresponsive.

Unfortunately, I don't get anything else in the logs and it's happening completely random

Hello. The selve component is not using mqtt. Please activate the debug logs for the component and provide any log to take a look. I've been using the selve component without issues for the last 3 years. (I have iveo). However I've planned to refurbish the component to use integration workflows and more "ha" official look. No ETA yet.

@gpulido yeah, ofc I know Selve connector has nothing to do with MQTT :) it's just a coincidence the MQTT error gets logged right after I/O Error 5

do you access your dongle using /dev/ttyUSB[x] or /dev/serial/by-id/xxx symlink?

gpulido commented 3 years ago

Right now I'm using the symlink as hassio keep changing the tty assigned on every update of the core :)

fss commented 3 years ago

OK, and possibly lame question: how do I enable debug logging on that component?

gpulido commented 3 years ago

Take a look here https://www.home-assistant.io/integrations/logger/

Btw, you at least should have a log showing any error, haven't you?

fss commented 3 years ago

it's always the same sequence before HA goes unresponsive:

@gpulido I might have a possible breakthrough 🙈

my Selve USB-RF stick is (was until this morning) connected via USB extension cable. this is my latest suspect, as I unplugged the dongle the HA crash immediately happened.

not sure if it's your module then or the Python-Selve dependency?

fss commented 3 years ago

seems it's either this integration or python-selve crashing and giving this untraceable I/O Error 5 which crashes the whole HA core.

I removed the integration completely and moved to Node-RED where I'm directly writing to serial port and it's now stable for 3 days straight (previously I wasn't able to beat 2 days)
