I have other projects running on other Pis and they have been running with 2 years uptime. I think it is something about the Magic Mirror application and maybe the Raspberry Pi 3B. I would switch to a Pi 4, but like I said, I can’t control the brightness with the Pi 4.
-
@raspberrypi9 MagicMirror is just a browser w javascript
unless there are gpio modules
does this pi3 have a fan?
do you get the same on the 32 bit os?
the stack errors sound like hardware problem
-
@sdetweil I am using a gpio module and a PIR motion sensor. I don’t have a fan. I am running bullseye 32-bit os. Should I try changing any of those things?
-
@raspberrypi9 i don’t know. i have pi3 w and wo fan
-
this can be caused by a specific module so you can try disabling one by one …
