ERROR weewx.drivers.acurite Failed attempt 1 of 10 to get LOOP data: [Errno 32] Pipe error

[Tom Farley]

Earlier this month the weewx web on my raspberry stopped updating the data displayed.

This system (rpi 4b) has been operating with weewx 5 for a while, for the past year+, it's running the latest os, bookworm.

I finally got around to looking at the issue and the acurite driver seems to be unhappy.

I have rebooted the pi,  change usb ports that connect to the acurite 5-in-1 base display, power cycled  the base. The  sensor has new batteries.

suggestions  on how I can resolve this issue or additional things for me to checkwould be appreciated.

Mine stopped on July 22 but I'm only now just getting around to dealing with it.

Seeing the same error after installing updates via apt on my PI4b that connected to the Acurite weather station. I see some python packages were installed, not sure if there is any correlation.

In the apt log:

The weather station stopped reporting after the updates were installed.

I'll keep poking away.

Tom, this sounds exactly like the problem I'm having, though mine started due to an install on new hardware, not a mere apt upgrade.

I've been discussing it here: https://groups.google.com/g/weewx-user/c/0Jiye8CmtLE

I'd love to hear any solutions.  I'm going to try Ubuntu on the Pi 5 in the next day or two to see if that makes a difference.

I installed Ubuntu and weewx worked fine.  See my post in the other thread above.

[Jeremy Markel]

I found this in the dmesg log on my PI4. It's running Raspbian; Linux 6.12.34+rpt-rpi-v8. Seems to be related to a recent kernel update?

[419128.775178] usbhid 1-1.2:1.0: probe with driver usbhid failed with error -22

Long story, short. I've powered cycled everything, changed cables, ports and more, and still get the same error.

I might do the same and just install Ubuntu on it and see what happens.

I also solved this by installing the Ubuntu image onto my PI 4 and my Acurite station connects perfectly fine.

I did back up all the config and what not and restore everything, and it's back in action so it does seem to be a kernel driver issue in Raspbian.
