Enviro Indoor locking up

Support
1

Dear Pimoroni,

I have two of your Indoor Pico W sensors running side-by-side on the same network with most recent firmware. One somewhat randomly fails. It seems to lock up, with the green light on steady, no pulse, and the log file looks like this…

I can’t tell if it is failing to shut down from the final cycle, or early in the startup, but it will reset properly with a push of that button.

Any suggestions?
Thanks,
Seth

I am having a similar issue on the Enviro Urban. There are no errors in the log, it simply says:

“2024-12-29 14:51:59 [info / 126kB] - shutting down”

Then nothing until I go and hit the reset button on the device. It will run for a while, usually less than 24 hours total, but occasionally for a couple days, and then hang again. I’ve seen this issue in this post and some other, similar issues in the forums and on GitHub - but I haven’t seen a solution, other than a couple of references to it being fixed in previous software/firmware versions. I am currently using v1.22.2.

If I had to guess, it looks like something is failing in the shutdown command so the board is never off when the RTC tries to wake it? I added a debug line after the shutdown command just to see if maybe it just kept running, but nothing gets logged.

Oh, and I’m not sure if it is related, but when I am looking through the logs and such on USB power, it never takes a new reading unless I manually run the main.py or do a reset.

I’m going to try the watchdog timer proposed here:
[0.0.9 - Enviro Urban - Exception while uploading - Caused board to hang fro 2hrs · Issue #119 · pimoroni/enviro · GitHub](GitHub: Enviro Issue #119)

Here’s the log (the Watchdog doesn’t appear to have helped):

While wake reason says rtc_alarm, it’s because I hit the reset button on the back of the board.
