Re: [weewx-user] Unable to remove or purge weewx! Really?!

[matthew wall]

kevin,

please post the contents of /var/log/syslog from the period of time when you 
did the 'purge'.  when dpkg fails on pre- or post-inst, it means that the 
installation package encountered a configuration that it was not expecting and 
that it was unable to resolve.  i'd love to know what state your system is in 
so that we can make the dpkg configuration more robust, and only with that 
information can i tell you exactly what you should do to clean it up.

If you host a public website from a personal Linux server, as I do, look 
into using fail2ban as a way to detect and block some bad actor bots.  My 
implementation currently has about 2500 IPs blocked because they were 
looking for typical webserver security flaws.

[weewx-user] Davis VP2 reliability with Rasp Pi zero

[iams...@gmail.com]

I've been using weewx running on a Pi Zero with no other tasks. 
Unfortunately, I live in a area that suffers power losses, often during a 
weather events, so I lose that data. What typically happens is that when 
the power comes back on, I get the dreaded "..page timestamp... less than 
final timestamp..." error. The only way I have been able to address it is 
to use the memory dump and clear.

 I don't understand why this happens since the VP2 is running with battery 
backup, yet the memory on the datalogger gets corrupted. Is this an issue 
with weewx that could be addressed?

Failing that, can I address this issue by adding a backup supply to my Pi 
Zero?

Thanks!

Thanks Tom!

Possible to write example, how to use weewx to lookup a string format for 
new units?

Thanks

Re: [weewx-user] Davis VP2 reliability with Rasp Pi zero

[Tom Keffer]

It should work.

What happens if you 'pull the plug' on your VP2? Does it keep running?
Perhaps the batteries are bad?

Personally, I use a UPS for both the weewx server and the VP2 and haven't
had a memory corruption problem in at least a decade. So, you could try
that.

Re: [weewx-user] Davis VP2 reliability with Rasp Pi zero

[iams...@gmail.com]

"What happens if you 'pull the plug' on your VP2? Does it keep running? 
Perhaps the batteries are bad?

Yes, it keeps running, that is why it seems to be a weewx issue to me. In 
other words, if the Pi Zero running weewx were not connected to the VP2, 
the data logger memory would not get corrupted. In fact, weewx is able to 
recover data that was gathered during the power outage (while the Pi is 
shut down). It is only when power is *restored *that the data logger 
corruption happens. At least I assume that is really the root of the issue, 
I really don't know. All I know is that almost every time the power goes 
out, I get the record time error and all data recording and uploading stops.

I've looked into getting a UPS for the Pi, which really appears to be 
nothing more than a $15 ext phone battery, but it seems to me this is a 
weewx problem that should be addressed. Alternately, I can contact Davis to 
see what they say.

It is much more likely your power supply being the problem.
