OK, that's done and I've checked that the cmon parameters are being written 
to the syslog.  Let's see what happens.

Have a Davis Vantage Pro 2 communicating with two Raspberry Pi 3B+.  One is 
communicating via the USB port of the console.  Second is communicating 
with the ISS via a SDR Dongle.

Re: [weewx-user] Attempting to switch to non-root user for rsync

[Steve Chiz]

Looks like the forecast.sdb database is generated by the the [forecast] 
report, and has the same issue with non-root /var writing. I created a 
/home/weewx/db folder, much like I did with for the PID earlier with 
home/weewx/run to get past the first error, and edited the wseewx.config 
accordingly. As I had mentioned previously I was writing the archive to 
mariadb, and was unaware that the forecast has its own database. For others 
who might be stuck, find it here: " SQLITE_ROOT = /" in the [Database 
types].

Finally running as non-root! And at the bottom of the log I was happy to 
see that my rsync worked straight away.

 Steve,

 Probably a leftover.
 I expect this should do it:

 $ sudo chown weewx /var/run/weewx.pid

 I would expect that file to be deleted on host reboot, except of course 
 it is pronounced reboot, but spelled:

 $ sudo shutdown -r now

 If you use actual "reboot" then it skips shutdown scripts, so it's a 
 big no-no.

 What about the other files, did you change their owner, too, such as 
 for the DB?

[weewx-user] Re: Lufft Ws600 UMB und ähnliche

[Stefan Schnidrig]

Hi Guys.
Can someone tell me whether the weewx system also supports the weather stations 
of the company LUFFT (www.lufft.com)? These are supplied with a Modbus and 
RS485 readout. I prefer the RS485, as it is easier. If this works, what do you 
need to set in weewx to be able to read the data? The picture of the sensor you 
see above in my post.

Many Thanks
Stefan

Re: [weewx-user] Re: Solution to bypass wee_database utility prompt

[Leon Shaner]

Hey, Christophe,

Sounds like you have been clever enough to write some code to find and correct 
those values.  Seems like you should be able to take the same logic and adapt 
it for use as python expressions and use the weewx built-in calibration 
features.

I wrote a post a while back, which may give you some ideas:

https://groups.google.com/forum/m/#!topic/weewx-user/veofTPb5adE

The first post there shows how I used python to test the eval statements, which 
I later put right into weewx.conf.  I did find out that you can't re-use the 
same weewx variable twice, which is owing to a weewx/python implementation 
detail in how weewx stores the calibration statements.  But there is a 
workaround mentioned in the second post.

Never mind that I ended up abandoning the idea.  What I show there is a sound 
approach to using a standalone python script to get the expressions working 
correctly, and then you copy/paste the exact same expressions into weewx.conf 
calibration section.

Meanwhile, if all else fails, have you tried piping "y" in your script?

$ echo y | whatever_comand_has_a_yn_prompt ...

There is also the "yes" command which just endlessly echo's y's forever:

$ yes | whatever_comand_has_a_yn_prompt ...

Regards,
\Leon

Someone else will have to answer - I do not use the forecasting extension - 
far too much messing around for me!!

I suspect it depends on exactly what you included, where on the page it was 
included, and how the css is being used.  Too messy for me I'm afraid.

[weewx-user] Re: Solution to bypass wee_database utility prompt

[Andrew Milner]

If it were me I would be trying to tackle where these strange windGust 
values come from when the windDir is 315!  Is it the console outputting 
incorrect data or is it the weewx driver corrupting the data as it reads 
it?

 If you have a database editor that introduces null strings rather than

 editor to solve the problem completely or just getting into the habit or 
 running wee_database to check for null strings after running the editor.

 in

Re: [weewx-user] Attempting to switch to non-root user for rsync

[Steve Chiz]

Well that added some confusion, but sort of helped as I figured out what 
you meant. I can't run Step#3, as I had removed the rc script based on the 
systemd wiki page "its almost certainly a bad idea to have both the rc 
script and a weeex.service file installed." 

That did prompt me to edit the weewx.service file and move the location- 
pidfile=home/weewx/run instead of var/run. As you noted, var/run would be 
difficult for non-root writes. Makes perfect sense to move it out of there. 
The systemd wiki page says 'make sure the paths match', but offers no info 
as to what they should look like, if not the default.  Maybe home/weewx/run 
should be the default.

The wiki also says to make sure that there are permissions to the weewx 
database, but I'm using mariadb and those credentials did not change. Now 
however, I see that there are other databases involved- that are not 
mentioned. The weewx user has no permissions to forecast.sdb, for example, 
which I find no reference to in either wiki page. Again, the read only 
error makes perfect sense and must come up every time someone tries to move 
from the root user, but I found no mention of it. Are there other internal 
databases that weewx creates/uses that I need to be aware of? The error log 
also reflects issues with items in usr/share/weewx/user and lack of write 
access. 

Am I the only one who has tried to hammer this out with such difficulty? 
I'm no noob, but I'm feeling pretty ignorant after struggling with this for 
so long.

[weewx-user] Re: Solution to bypass wee_database utility prompt

[Andrew Milner]

30 errors per day seems to be excessive.  Do you have something causing the 
errors?  What kind of errors are you correcting? Recalculating the daily 
data from the archive data is, I would have thought, likely to create more 
'errors', and possibly lose max gust data which may have been in a loop 
packet for example.  How do you know the recorded data is wrong, and how do 
you know what the correct value should be??  All seems to not make much 
sense on the face of it.  Maybe your best option is to create your own 
special version of wee_database which does not issue the prompt request so 
that you can run it via cron (although running wee_database via cron seems 
a wrong thing to have to do anyway!)  Surely though you only need to do the 
recalculation after editing the data - so why not just include the call to 
wee_database within the script you invoke when you decide to edit the 
data.  I assume the actual edit is a manual process.  Maybe understanding 
what your problem is caused by would shed some light on how to correct it - 
at the moment I feel somewhat lost.

[weewx-user] Re: Solution to bypass wee_database utility prompt

[Christophe CAVALLIÉ]

I make the corrections myself via a mysql command executed by bash shell 
script and I must therefore perform a frequent recalculation of the daily 
data because I have up to 30 errors on the wind speed and wind gust data 
per day.

[weewx-user] Re: Solution to bypass wee_database utility prompt

[Andrew Milner]

what kind of errors are you correcting with the utility??  If you are using 
checkstrings/fixstrings this should not need to be run on a regular basis 
via cron since it is really finding and correcting errors introduced by a 
database editor.

If you have a database editor that introduces null strings rather than null 
values when deleting values then I would suggest either changing the editor 
to solve the problem completely or just getting into the habit or running 
wee_database to check for null strings after running the editor.

[weewx-user] Re: how do I change my password at wunderground?

[Andrew Milner]

as far as i can see the api requires only an apikey  - not a password.  Are 
you sure a password is required?  I know one is specified in weewx.conf but 
is it actually used??  If one is required I would suspect it would however 
be the password as it was at the time the key was generated (suspicion says 
the apikey could well be a hash derived from station id and password).  
Further thought makes me think that maybe you have to generate a new apikey 
after changing the password in the members/station section.  Tom must 
generate the api key since it is not specified in weewx.conf - just station 
id and password it would appear.
