NOAA fles not updating

[WindnFog]

Hi guys,

I noted this morning that my /var/www/html/weewx/NOAA/NOAA-2022-01.txt is empty.  It was OK yesterday.  I'm running weewx 4.5.1, and the  Raspbian O/S is up to date.  The documentation says, "It is not necessary to backup the generated images, HTML files, or NOAA reports since WeeWX will easily create these again."

The file time gets "updated" every 5 minutes, so something is "touching" as expected, but it's empty.  All of the previous ones are OK.

Is there a way to force it to regenerate the NOAA files, or is something broken if it won't do it on a reboot or stop/start?

As always, I didn't change anything except rebooting a few days back.  I can include logs, configuration files, set debug to 1, etc., but I'm hoping someone will say, "Just do XXXXXX", as in just delete them all and wait 5-10 minutes?   Thanks in advance.

You didn't include a log, so I'm going to take a wild guess that you're using a Davis Vantage and that the logger memory got corrupted. If that's the case, see the wiki article WeeWX generates HTML pages, but it does not update them.

If that's not the case, include the log. Stop weewxd, set debug=1, restart, post the log from startup to the first reporting cycle.

We had a rough 24 hours of high winds, freezing rain, and snow. We didn't lose power, but the logger may be corrupted due to a surge or spike on the line. Everything looks good except the NOAA files, so it could well be what you suggest, Tom. I will try what's indicated on the link you sent tomorrow.

It's a Davis Vantage VUE, and I know the posting rules. I was hoping for a quick fix, but I understand you guys can't hand-hold thousands of us without the logs, etc. I'll get back to this and report my findings as soon as possible. I need to sleep now! :-)

The problem was hardware, but not the logger or the Davis weather station. After replacing everything except the Pi board, it still wasn't working. I then rebuilt the system on a 4G Pi, and everything is fine. Either the original Pi board had a hairline crack somewhere, or its USB circuitry was damaged due to heat or pressure. I used a cheap case that, while designed for a Pi 4, didn't have a fan, and the aluminum "prong" meant to affect passive cooling on the USB control chip was not seating correctly. This one:

Thankfully I had a spare Pi 4 board. Unfortunately, the 2GB/4GB/8GB versions seem to be sold out worldwide. No doubt, they will be far more expensive whenever they return to the market.

Since the rebuild, I've upgraded to weewx to 4.6.0 --> 4.6.1 --> 4.6.2 with no issues. Thanks to Tom et al. for pointing me in the hardware direction.
