[weewx-user] How important is it to do virtual environments for all installations?

[D R]

With my Pi5 having arrived and run in for a week or so and a multitude of 
projects now under control, I want to start playing with WeeWx 5  (or 5.1).

I plan on a fresh install on a freshly updated Reap OS installation.  I 
expect to fiddle with it a lot, and if my past experience is anything, a 
few complete re-installs .

I've seen it mentioned that it is important to do all the WeeWx in a 
virtual environment.  I really don't have anything important on this 
computer, have been pretty good at installing according to instructions for 
previous versions, and now wonder if it is crucial to do Venv, or just go 
ahead as I have?  I'm seeing Tom say that Venv is a piece of cake, but 
until I figure stuff out (paths especially) I want to cut out anything 
which my interfere with learning and configuring.

Am I foolish to not try to master Venv until my final install? Are there 
bad actors lurking under every stone which I should be more concerned about?

Thanks. Dale
Oh, is it OK to begin to use 5.1 as a learning and testing program?  For 
awhile it will be just running the simulator, I think.

Re: [weewx-user] Weather Display and weewx

[D R]

I am getting a Campbell Scientific running with major help from a user who
has accomplished that already but am thinking while focused drivers are no
doubt the best interface, I was next going to try using Weather Display to
write the clientrawtext.txt file and the modify Mr Wall 's file parser to
pull in the values to present to weewx. With my skills it is likely to be
late summer Northern hemisphere before anything is working so feel free to
come up with a correct driver. If you do, please share.  Dale

Re: [weewx-user] Plot for progressive rain accumulation

Kevin,   Yes, that is the one.  

After I get my WeeWx updated and tweaked, I will work on getting the 
Belcher 1.3.1 installed.  Dale

[weewx-user] How to copy error messages and other info from the Terminal window in RaspPi400 standard install

[D R]

i'm attempting to install and use Mr. Wall's most recent driver for the 
Texas Weather WLS-8000 driver.

I downloaded from github, copy and pasted from the readme file the 
instructions and pasted them into the Terminal and executed them in 
sequence.

When I get to the reconfigure sentence, I get an error message, with the 
walk back, when then says another error message is preceeding it.

It has to do with permissions for the weewx.conf file and also something 
about shutil.

I attempted to highlight them in the terminal window, did a copy, but the 
pasting of the error sequence to this firefox browser window opened to the 
Google Groups Weewx-user panel (which I'm typing in right now) does not 
paste.

I know this seems dumb but i cannot copy and past either the error in the 
terminal window, nor the /var/log/syslog file to show those familiar with 
such things what seemed to happen.

Is there some other way to capture that error and send it to this group for 
comments and help?
Dale

I perhaps spoke too soon:
I went back to complete the install, and got this:

Re: [weewx-user] Re: After installing Texas Weather driver from Matthew's github no in pick list

[D R]

I downloaded the twi.py which you furnished at the above link, and copied 
it from the pi/Downloads directory to the /usr/share/weewx/user area and 
re-ran the wee_config --reconfigure program, but again only 12 choices were 
shown and the TWI was not one of them.

I'm sure it is my error with the trouble I had trying to move the file from 
my download directory to the /user area.

I even tried modifying Mathew's install instruction to do so too but it had 
a run error so I guess that isn't going to work!

I will try later after I rest my brain a bit, but am I correct in assuming 
the procedure to do is to download the twi.py you provided, move it from 
the Downloads area into the /usr/share/weewx/user area after removing the 
previous twi.py file, and then run the wee_config again, or have I missed a 
step?

Thanks and sorry to be gumming up the works here. Dale

[weewx-user] Re: After installing Texas Weather driver from Matthew's github no in pick list

[D R]

I did forget to mention that I found twi.py in the /usr/share/weewx/user 
directory.  It is puzzling to me that there were no other drivers from the 
list shown during the wee_configure --reconfigure selection shown here, 
unless they are stored elsewhere or 'built in' and not visible, and the 
twi.py is added on somehow.  Dale

[weewx-user] After installing Texas Weather driver from Matthew's github no in pick list

[D R]

I am past testing and now want to connect my Rasp 400 to a real wx station 
I have running, a Texas Weather Instruments.

I went to github and got the driver that Matthew has furnished, downloaded 
it and installed with the instructions given into my WeeWx 4.8.

Then I did a wee_config --reconfigure and was stepping through the choices 
until lI got to the 
Installed Drivers choice, and in the 12) shown, there was no mention of the 
newly installed TWI driver.

Is there a way of making it show up in some way other than wee_config,?

Thanks for any suggestions.  Dale

Re: [weewx-user] Has the latest WeeWx and Python3 changes made the github fileparse.py file not work?

[D R]

I am learning about Github, too, and didn't realize such info was posted 
and things list updated to Python3 was in those files.  I'll know to look 
there in the future.  Thanks!
No, I'm not having any particular problem.  I just printed out the 
fileparse code and wanted to study it to try to figure out how things are 
done, a learning exercise, to see if I can then go the next step and make 
the output of the Weather Display clinetraw.txt or some such file, and then 
learn how to take that, extract the data, then format it into a file that 
fileparse will read and furnish to WeeWx.

I'm not anywhere as far along as you were thinking when you asked if I was 
having a problem!  Certainly not with WeeWx, just me learning.  Thanks.

[weewx-user] Has the latest WeeWx and Python3 changes made the github fileparse.py file not work?

[D R]

I am getting my bearings in the skins and language structure and got one 
weather station (rainwise ip100) back working.

While still very shaky with the details of the language, thought I might 
exercise my brain by trying to get my Campbell Scientific station feeding 
Weather Display to also make the file necessary so that using Fileparse to 
read a file so the beautiful graphics of WeeWx can be posted to my web 
server, along with having more weather information available than what the 
aging RainWise station can provide (like solar, snow depth, etc.)

I see the original file was written in 2014, and that the last modification 
(if that is what a commit is) was in October of 2019.

Since then WeeWx has been updated a few times, and Python3 is what I'm 
running.  I've seen that some comments on other code is that Python3 
doesn't always go backward to run old code, so as I study the situation and 
try to figure out how fileparse works, and whether or not Weather Display 
can be configured to write a file that fileparse will successfully read, it 
would be nice to know if that block of code is compatible with the current 
WeeWx 4.5.1 and the last python3 distribution package.  Has anyone run 
fileparse with the latest releases?

Thanks. Dale

[weewx-user] Set up Belchertown for using Dark Sky for the time being for forecast

[D R]

Since I'm just getting my station rebuilt and set up, I cannot get an aeris 
key or password yet since I"m still running the station emulator and 
getting simulated data.  Of course with DS on the way out, I will feed 
pwsweather and be entitled to get a key, but so far, I'm not online.

I'd like to proceed with getting Belcherweather set up.  Pat has apparently 
been busy and so far hasn't answered a question I posted on his site.

In the configuration skin for Belcher, there is a section that says 'aeris' 
is the forecast source, but says Dark Sky for those with a still 
functioning API can be used, but there is no example that I can find as to 
what to put into those " " for DarkSky.

Has anyone set this up for DS and know what the entry should be?

Re: [weewx-user] Getting pyephem to generate more extensive values in the Celestial module

[D R]

Tom K.  Do not spend more time on this, I just did a power down and 
restarted Debian and then went through start up with weewxd and it now 
works.  I know that Linux is supposed to be vastly different from Windows 
and 'reboots' not usually needed, but it wasn't working before the restart 
but does now.  Please use your advising time for someone else, since the 
problem seems to have been fixed but I have no understanding of why.  I'm 
just pleased to have Celestial.inc working!  Thank you.

[weewx-user] Getting pyephem to generate more extensive values in the Celestial module

[D R]

I've started a new install with a RaspPi4, 64 Gig memory, latest Debian 
install, with updates, then latest WeeWx, selected the emulator to get some 
reports, then when working went through the install of pyephem, since when 
I expanded the Celestial .inc it told me for more info I needed that. I 
went to the site to install the pip dev package, then ran 
pip3 install ephem and got
Successfully installed ephem-4.0.0.2 message 
then ran
python3 -m unittest discover ephem 
which game me, eventually, Ran 160 tests in 7.843s
OK, skipped =2.

I then restarted weewx with the 
sudo  /etc/init.d/weewx stop
sudo  /etc/init.d/weewx start 

and since I have my ftp turned on my
sudo tail -f /var/log/syslog 

gives me streams telling me main Starting up weewx version 4.5.1
with clock correct, wx_binding to database weewx.sdb
then starting main packet loop.

After a period of time,  there are cheetah reports of generations and 
uploads to the ftp site which do show up.

However, when I try to expand the Celestial area on the left of the screen, 
I still get the very basic couple of lines and the message that I need to 
install pyephem if I want more detailed informatiion.

There isn't much info in the syslog/log that shows me what's going on and 
it is getting longer, but I will be willing to attach that if it is the 
right log, or is there a different log that is more helpful in trying to 
figure out what I need to do in order to  have WeeWx know that ephem is 
loaded?

I see that it is referred to as pyephem in some places with internet 
searches, and in others ephem, so I may have done something wrong.

In addition, once when I started WeeWx, I got about three lines of 'dummy' 
information displayed on the screen about every two seconds, but I don't 
see that in the log anywhere, but it seems to be generating the information 
to try things out before attaching a real weather station to the program.

If hints are available for me to try, please let me know.  If there are 
other logs to capture and load, let me know that otherwise I'll be happy to 
load /var/log/syslog for inspection.

[weewx-user] In which directory on the Rasp Pi are the driver files stored?

[D R]

I'm starting from scratch with a new Rasp Pi 4, Debian OS, and installed 
the newest version of WeeWx with the method that placed the bulk of the 
files in the /etc/weewx directory, not the /home one.

I have found the 0.5 release of the Rainwise IP100 driver and ran the 
program to add an extention, and found it listed in the weewx.config file 
as the driver.  I've edited the .config file to include the IP address that 
the IP100 is on my system, but get an error when I try to start weewxd.

Before posting more info and asking questions I'm trying to learn more by 
exploring the possible errors myself.  I want to verify that the IP100 
driver did get loaded in the right place, but cannot find it snooping 
around in the various bin areas.

Maybe it is elsewhere? Maybe it didn't get loaded as I thought it did.  So 
to start with, may I ask where I should check to see if all the driver 
software got loaded?

Re: [weewx-user] tag date and time of the last rain

[D R]

I'm reminded of Ray Bradbury's wonderful and chilling short story, "All 
Summer in a Day."


Free online and a quick read.  I still get shivers when I think of it.

[weewx-user] Formatting question: How to force a + in output?

[D R]

If the number is negative, it will print a "-" in front of the number.

Despite looking through Python formatting pages from searches for Python 
Formatting, I cannot see that there is a provision to force a "+" in 
front of a number no matter what.


For example:

-23.7 is always given if negative,

45.2 is given but I'd like +45.2

Is there a formatting character to do this?  I guess a long logical 
string to determine if the value is greater than zero, then toggle to 
print "+" if true, but that seems more than what I want to waste CPU 
cycles.  I was just hoping that some character had been assigned to 
force a +.

[weewx-user] How to insert a special symbol in the format and labeling text

[D R]

I have made some changes to the current.inc skin generating file and now 
want to tweak it just a smidge.



In the current conditions, listing the various values, I used the 
($trend) operator to get the difference from 24 hours ago.


I had it in a line at the bottom of the listing of values, but see that 
the barometer uses a (...) form to indicate change.  I stuck the 
formatting for the temp difference after the current outside temp, 
within () and it works. Now I'm feeling brave and would like to add the 
capital Greek Delta symbol in front of the value.  I know it may be a 
little odd for someone who might casually look at the page, but this is 
for me.  I know in Word or Excel you can hold down the Alt key and type 
in the value, but I don't know if that is exclusively for Windows 
environments or not.



I looked in the skins.conf and also for the default values for the 
database element values, but didn't find a delta that I could copy and 
paste.


Is it possible to insert this character?  I know some special characters 
do show up, like the degree sign in F and C, and wind direction, so the 
Cheetah engine must be able to do it.


May I ask for what that might be, or point to an area that explains how 
to do such insertions?


Thanks, Dale

Thank you for the replies on my question.  I think I have figured it out 
and now have a better understanding of how things work.



It is not always as one thinks it is!

Again, thank you for the replies and guidance.

[weewx-user] Looking for guidance on how to modify the Current Conditions section of the 'main page' of WeeWx

[D R]

I apologize for not having come up with the answer on my own.  I have 
gone through the User and Customization guides and am just not finding 
clear guidance as to what to do, despite there being a lot of info in 
those documents.



What I want to do is add a line to the collection of items in the left 
hand "Current Condtions" list.  This section preceeds the "Celestial" 
and "High Low" portions of that column, and lies to the left of the 
graphs for the day.


From my reading, I assumed that the area I was looking for would be in 
the /etc/weewx/skins/Seasons directory, in the 'skins.conf' file.  Yet 
as I scan through there I cannot find a series of entries that matches 
the fixed output that would then have the data to display and formatting 
info right after it.


I've looked at the Standard report, and the skins.conf there, and 
haven't found what I'm looking for.


Despite fiddling with this for a couple weeks trying to figure it out on 
my own, I'm just not making the connection or am really looking in the 
wrong spot.



Where does this section of the home page get formatted and while I think 
I know what I want to add so it shows up as the temperature change from 
24 hours ago, don't just want to start changing things which would no 
doubt give an error if not done carefully.


Can someone give me a hint as to what I'm missing to find the correct file?

Yes, why not, indeed!

This program holds so much and thanks to the development and design, 
makes this one far easier.

[weewx-user] Noting temperature change from yesterday at this hour

[D R]

One of the things we get are these rather sudden sweeping in of cold air 
masses and the television stations frequently map how much temperature 
change there is compared to yesterday at this time.  In the summer, a 
welcome cool front is also frequently given air time.



I'm thinking this would be an interesting value to show (perhaps 
choosing to show or not in the .conf file.



However, I quickly proved to myself how little I know about going to the 
database SQLite and plucking this number from yesterday at the closest 
time, and then displaying it like was done with the "Rain Yesterday" 
modification that was offered maybe 8 months ago.



Has anyone coded this function, and given it a 'toggle' to choose to 
display this, perhaps in the High/Low portion of the home page, or 
Current Conditions?

Re: [weewx-user] forcast wunderground for weewx 4.2.x using python 3

[D R]

The weewx is 4.2.0  Installed quickly, no errors, and is running in test 
mode with the simulator showing what I'd expect. I have downloaded all 
the install files within the last two days.


I did an update and upgrade for all things on the Rasp400 before 
installing it.


The github location was: https://github.com/matthewwall/weewx-ip100 



Yes, and I did try giving it the absolute location as you indicated.  
And I tried moving the file to the /weewx directory, but it said I 
didn't have permission to do that.  Not knowing Desbian very well, I 
just assumed I made a mistake that I couldn't surmount at the time being.

[weewx-user] Most current version of driver for Rainwise ip-100

[D R]

I am doing a new setup on a Pi400 for speed and to clean out some things on 
a previous Pi4 that I've had running for about 1/3 of a year.   I have 
downloaded the driver from github, and searched here for comments on the 
driver which seems to have had some problems pre version 0.4

Despite having downloaded the github's most recent version, and following 
the instructions in the readme file, I run into a file not found error when 
I get to the part of doing"
 sudo wee_extension --install weewx-ip100.zip

I see that the file actually downloaded from github is called 
weewx-ip100-master.zip but even changing to this name in the command, I 
still get a file not found error.

Is there a posting of a correctly named install file, and a readme of the 
correct instructions to get the driver installed?

I seem to have run into a wall, and perhaps there is an obvious error I'm 
not seeing for having looked to long at the sequence tonight.

Thank you for any tips:  Dale

Oh, PS.  Is it possible to have two WeeWx installations (on different Rasp 
machines) BOTH looking at the ip address of the unit and have correct data 
flowing to both Pis?  I'd like to not take down the functioning Rasp Pi 
until the new install is up, running and tweaked.

Re: [weewx-user] Re: Peet Bros with Davis wind vane

[D R]

Indeed, I may have jumped to a wrong conclusion, also.


I should have clarified.  My response was based on getting a whole 
sensor unit, windspeed and wind direction, replaced.



If it is just a mechanical problem (broken  nose or fin) on the Peet 
wind direction unit, then as Tom suggests a bit of work with epoxy and 
re-inforcement mesh works wonders.



I have just finished fixing the nose of my Peet unit that arrived with 
the nosepiece broken off and a little of the screw pointing through.  
Very easy to do.



I have made numerous repairs to the wind direction vane on the Texas 
Weather Instruments sender because it is notoriously weak where the bolt 
attaches the vane to the encoder.



Please indicate what you are wanting to replace:  The whole unit with a 
Davis, or just the VANE that turns the cap with the magnet inside of it.



Dale

[weewx-user] Re: Peet Bros with Davis wind vane

[D R]

In those situations where a conversion can be done, rather than a direct 
drop in replacement, it usually takes some electronic magic.  Davis made a 
unit to take an NRS or RM Young wind monitor and simulate it being a Davis 
weather sensor package.

A gentleman in Florida did a whole bunch of programing to make a Davis head 
look like a Heathkit ID-4001 or 5001, but he did that for a living.

This is going to be tough since I don't know if anyone is privy to the 
actual workings of how the Peet Bros figures out the angle from the 
pulses.   I can see the concept but have no idea how to emulate it.

[weewx-user] Re: Peet Bros with Davis wind vane

[D R]

>From my knowledge, the answer is no.

The Davis uses pulses to signal wind speed, and the Peet Bros does, too.

The major difference is that the Davis uses the much more traditional 
potentiometer to deliver a voltage and the ISS reads that to convert to a 
wind direction.

The Peet Brothers does something much more difficult and very different.  
It times when one of the magnets makes or breaks and then depending upon 
the time until it pulses again, determines the angle of rotation through 
which the wind speed magnet has rotated, simplified explanation.  
Therefore, if there is  no rotation of the wind speed magnet, there cannot 
be a determination of which direction the vane is pointing, unlike a 
no-wind condition for a Davis, which of course will give a voltage on the 
wind direction sense line.

Very odd, but seems to work for them.   If you go to Davis's web site, 
there is a better explanation of how they designed their unit.  It 
certainly gets rid of the potentiometer and it wearing out, but the timing 
circuitry to measure the angle has to be a bit more complicated.

[weewx-user] Is there a clientraw driver?

[D R]

I have used WD for a long time, and have it monitoring several stations.  
The program generates a clientraw and clientrawextra file, as well 
discussed here.

My stations can feed only one software program, therefore I cannot run 
WeeWx and WD on two computes.

I would like to use WeeWx to generate its various display skins from data 
which WD generates.

I see that WeeWx can generate a clientraw type file for use by WDFresh and 
WDL, but that is backwards from what I want to do.

I am looking for, but not seen,  a driver that allows WeeWx to *read  *a 
clientraw file produced by WD and loaded into a location on my Rasp Pi (WD 
runs on a Windows 10 machine) which WeeWx can then do its magic on to make 
the various outputs based on the skin(s) selected.

Is there a driver that does this?  Is there a driver that is 'close' and 
would require me to produce a bit of code that would do the conversion of 
clientraw from WD to a format that WeeWx driver could read?

Thanks,
Dale
