Re: [weewx-user] Re: Roughly how many weewx users are there?

2023-03-14 Thread Paul Dunphy

Thanks, Jonathan. Those stations are the ones who voluntarily
chose to register their station with the weewx registry. That is a
field in the weewx.conf file that defaults to not doing so, specifically:

[[StationRegistry]]
# To register this weather station with weewx, set this to true,
# then fill out option 'station_url', located in the [Station]
section above.

register_this_station = false

According to the weewx authors, there's no accurate way of knowing
the number of active users. They know the number of downloads of the
software, the number of subscribers to the discussion group, etc. None
of these metrics indicate the correct number of active users. Tom's
"best guess" is about 10,000.

When anyone asks me, I say "I believe around 10,000."

Re: [weewx-user] Re: Davis Data Logger - Issue

2022-05-18 Thread Paul Dunphy

    Whatever it is, it's related to RPis talking to a Davis Logger via 
USB. I have a couple of powered USB hubs lying around. I can try putting 
one of them on in the next day or so . . . now that you mention it, I 
never had any trouble with an RPi 3. However, it did/does manifest 
itself on three different RPi 4s. I'll report back when I have results 
using a powered hub.

The USB power supplies for many RPis can be barely adequate. In 
particular, the RPi 4 uses a lot of power. It doesn't take much for 
the power to sag, resulting in errors.

Re: [weewx-user] Re: Davis Data Logger - Issue

2022-05-17 Thread Paul Dunphy

Me either, Tom. Since it's intermittent, I might be jumping the gun
in claiming that it fixed things. We'll have to wait for the others to
weigh in. I've got some outside things to do today, but once I get a few
hours, I'll warm and cold reboot it to see if I can reproduce the error.
It might be something oddball like a few extra lines of code are
changing something in the timing. Those loggers are flaky, so who knows?

I will also dig into the $month.rain.maxsum and $month.wind.maxtime
items. I couldn't find anything obvious in the documentation, so I wrote
a small python program to pull the data out of the NOAA files. I thought
there had to be a better way. Now that I know there is, I'll simplify my
approach and get rid of that cron job.

Re: [weewx-user] NOAA fles not updating

2022-01-15 Thread Paul Dunphy

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! :-)

Hi guys,

I noted this morning that my

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 XX", as in
just delete them all and wait 5-10 minutes? Thanks in advance.

    sort_array[j]   = sort_array[j+1];
    sort_array[j+1] = temp;

// Sort them. Use quick and dirty bubble sort because it's a small

Thanks to Vince and Karen. I should have clued in on the % sign on

weather stations (i.e., a weewx change), or is it an "It depends on your
hardware?"

If it bothers you that much, you could add a cron job that resets

Re: [weewx-user] Odball stuff after system tuned off over night

2021-03-29 Thread Paul Dunphy

Thanks, Tom. Unfortunately, I went to have lunch, and when I came back,
it was working. This tells me it's dependent on something in the input
data that changed. I'm calculating Beaufort Scale, doing C to F
conversions, for example. It's windier now than it was at 6 AM. Or the
sun angle is different. Or a dozen other things. Bugs that "fix
themselves" are the worst kind. Look at that website now, and it's
working like it was all along.

I will scour my index.html.tmpl file for multiplies to see if I can find
the "None," but no doubt there's an if statement or the like that isn't
true (or false) most of the time. Talk about your needle in a haystack.

Regardless, when it occurs again (should I not find it by looking
today), I can start commenting out chunks of code like a binary search
and narrowing it down in short order.

Somewhere in /etc/weewx/skins/Standard/index.html.tmpl you are trying
to multiply two numbers together, and one of them (the first one) is
'None'.

Scan the file and see where the multiplication is occurring. Then
check the value for None before multiplying.

Re: [weewx-user] wee_reports picks up extensions.py delay

2021-02-27 Thread Paul Dunphy

Thanks for the quick reply, Tom. This makes sense. I had the 45
seconds in there from some debugging 6-8 months ago and I really don't
need it anymore. Just removed it.

Unfortunately, wee_reports has to load extensions.py, because there
might be some user extensions in there, which it might need for the

is going to get executed.

I no longer think an arbitrary 45 second sleep is such a good idea.
The engine already has something that causes it to wait until the time
is greater than the timestamp on weewx.conf, so that should give some
measure of protection against clock slew. But, the best way to
approach the problem is through systemd time synchronizations.

If you really want to sleep, then it's probably best done with a WeeWX
extension that's bound to the STARTUP event.

Here's an oddity. To delay weewx from starting for 45 seconds

well, except it also kicks in when you run wee_reports:

*sudo wee_reports

File "/usr/share/weewx/user/extensions.py", line 20, in

Is there any way to change the code so that wee_reports doesn't
execute the time.sleep(45) command?

I always get it eventually, but often it takes some iterations. I

force it through Cheetah and weewx without having it blow up and
not update my website, etc.

If there is, I can fix errors and warnings while the "production"

Reading the list archive, the documentation, and searching the

system and a cloud server at 01:18 AM daily. Since I only write
archive records to the database at XX:00, XX:05, XX:10, etc., I
*think* this is safe. The documentation says:

"Do not make a copy of the SQLite database while in the middle of
a transaction! Schedule the backup for immediately after an
archive record is written, and then make sure the backup completes
before the next archive record arrives. Alternatively, stop WeeWX,
perform the backup, then restart WeeWX."

I prefer not to stop/start weewx every day, but I will if
necessary. Are their situations where some part of weewx could be
modifying the database between the archive writes every 5 minutes?
I have done a couple of restores over the past 4-5 years with no
issues, but am I playing with fire?

What are you guys doing vis-à-vis weewx.sdb backups?

I can answer your question. WEATHER365 is running a beta network at the moment 
and we think we can go live with version 1.0 of our network in the next 2 or 3 
weeks. We still build a network especially for farmers in Germany/Europe, but 
we are open to all stations running weewx.
Our main page is  https://weather365.net.  We run own build numerical weather 
models on our HPC systems since more then 20 years  and with the new stations 
network we want to try to improve our numerical forecasts to get better results 
especially in the regions. It´s a project for the next 2 - 5 years from now.
You can have a sneak preview on the stations at https://stations.weather365.net 
...You will see a lot of airports and some stations in the southern part of 
germany we´re testing. Zoom into Germany South - Donau - Bodensee - Alpen   
  //
Registering new stations / test-stations in this BETA phase is possible by 
sending a mail to  i...@weather365.net.  Everybody taking part and share the 
data with us will get unlimeted access to our forecasts - thats the plan :-) .  
  We prefer stations like DAVIS VUE or DAVIS VP PRO ..

Hi Dave,

I have fixed my forecast issue as I mentioned on the Google 
groups.  Also I'm now using VE1DX for my CWOP uploads, thanks to you 
giving me the passcode and suggesting I use the server rotation.  I used 
to be EW8606 for a year or so, and I really disliked not using my call.  
That's fixed.  Oh, any reason to use a SSID?  I am just using VE1DX, not 
VE1DX-13 or anything else.  I seem to recall the SSID was important back 
in the packet radio days (I ran a DX Cluster for 13 years until 2015.)


I gave up DXing last year and sold all my HF gear . . . even the 2m 
stuff is gone.  No more CW, SSB, RTTY, Packet, etc.  It's the 21st 
century.  I had them all worked and confirmed on HF anyhow, on multiple 
bands and modes, so couldn't see the point of listening to hissing and 
static to get one more band country.


Also, yesterday I really drilled down into the guts of weewx and 
learned a ton.  I just needed the incentive.  Your postings are very 
helpful.  I find many of the other topics really advanced . . . and 
while they now make sense, I didn't want to try to "start" at the PhD 
level.  Those guys are really sharp, but I find the group not very 
conducive to beginners.  I came from a group headed by AA6YQ (also in 
MA, in spite of the 6 call) who wrote and maintained a suite of logging 
software called DX Labs.  The attitude there was "The only stupid 
question was the one you didn't ask" as opposed to "Didn't you read the 
documentation 12 times before posting that question?"  It weeds out 
those with little interest, but it can put off a lot of people who 
*really* don't understand the system.  It's a great project (weewx), but 
it's not something you can jump into and make sing and dance easily.  
The learning curve is steep, in my opinion.


Anyhow, I home you are not an MIT PhD, or I've probably said too much!

73, Paul VE1DX
