To be hoped.
And let us know either way.  :-)

Information is king.

Hopefully I've supplied enough over on my fork, I've update the readme
with a note to read the pydoc output at bin/user/pydoc_owfs.txt which
is in the repo (also the zip file) if you need to know more (possibly
than you want to) about some of the quirks of the drivers
installation.

If you find them lacking in some measure, let us know, here or at github.

When you're close to something it takes a special skill to write good
documentation as we all tend to make assumptions from our own
knowledge base.

Now that this driver can run with 1 of 2 modules, as well as the 2
python versions involved it's all got a lot more complicated and
that's without adding owserver and the busmaster devices into the mix.

>From your end.

1.
If you need to send a log extract, include plenty of it, and forget
about sending the short systemd log. Make it a copy, or large extract
from syslog, from start to finish.
The owfs.py driver will log the module it is using straight after
weewx starts up and that alone is valuable information. weewx also
logs the python version that it is using and that is also essential in
this case.

2.
Need to know the complete [OWFS] entry from weewx.conf, In fact, it's
best to use the  wee_debug tool and send the lot.

3.
Finally your complete /etc/owfs.conf file

:-) And when it does work!

Good luck.

That thread was restarted as "V4 with python2 OWFS errors" and was
resolved there, with two working installations at the finish of it.
One with python2.7, the other with python3.

I also have direct access to 3 weewx4 installs, 2 under Debian Buster
and 1 under Devuan ascii. They all use owserver with either python-ow,
python3-ow (yep, python3-ow) or pyownet  running owfs.py. They all
work with either python2.7 or python3 (dual installations)

[...]

python3-ow has disappeared from the repos but the modified driver will
use pyownet as a drop in replacement. So you can run weewx4 and
owfs.py with either python version.

If you install weewx4, whether you use python2.7 or 3, you will be
using a different driver to the owfs.py driver you are using now. (I
don't think the 0.21 owfs.py driver was officially ported? You could
of course try it anyway with a weewx4/python2.7 install but I'd expect
it to fail.)

In short , there is a version of owfs which runs under weewx4 and
python3, or python2.7

The driver at

https://github.com/matthewwall/weewx-owfs

had some issues which were resolved in that second thread by using my fork at

https://github.com/glennmckechnie/weewx-owfs

My fork definitely works for weewx4 and python3 or python2.7 and if it
doesn't I'll do my best to fix it. That fork is also in mathews long
queue to be merged (where appropriate) back into his long standing,
and supported, driver so there is and will be ongoing support for owfs
from the one source.

The only issue left is with owserver and that has a possible solution
for a vague problem. And that's if it is even an issue on your
installation. The readme.txt on my fork covers what has changed and
solutions where they are known.
It also covers the configuration of owserver.

I'm not sure whether you are running owserver (I've lost track along
the way) and if you were uncertain, then installing owserver first and
seeing if it starts and runs for you would be one approach before
actually committing to any change.

Rest assured, if you go the down the path of weewx4 and owfs.py you
won't be left stranded by weewx-user and issues with owfs.py

My only nervousness is with owserver as there has been no definitive
solution for that vague, but occasional, show stopping issue. Once
owserver does start it seems to keep going, judging by the silence -
go figure!

I should add, the issue with owserver is a system issue (Buster
specifically), it is not a weewx issue. That's why if you have
owserver  running already then I don't see any problem, The owfs.py
driver is working, and it can be modified if need be.

No, it will not overwrite the existing weewx.conf file, nor the database.

Do a backup if you are concerned.

You can add more temperature sensors to your existing schema. Follow the
directions in the section *Adding a new type to the database* in the copy
of the Customizing Guide *that came with your 3.9.X version* (Version 4.x
uses a different method).

If you wish to use Python 2 on buster, use the Debian 9 (squeeze)
instructions:





*wget -qO - http://weewx.com/keys.html  | sudo

Re: [weewx-user] Suggestions on best way to upgrade to 4.1.1

2020-06-21 Thread Michael Form 

Tom:

Thank you for your response. I was aware of this issue which is the 
reason that I asked if there was a way around it. The thread does not 
seem to indicate a solution.


Assuming there is a workaround, how to upgrade without losing the 
configuration (weewx.conf) and the previous data in the database, etc.


One of the reasons that I would like to update to 4.1.1 is the greater 
number of temperature inputs in the schema. I have run out of 
temperature inputs and still have four or five more to add. I assume 
that I can add to the 3.92 database setup but I am a hardware designer 
and am afraid of messing thing up in Linux and Python and so forth.


If there is no solution to using owfs under Python 3, how do I install 
4.1.1 and specify to use Python 2?


Thanks for your help in getting this resolved.

Michael

want to tempt fate by upgrading to Weewx 4.1.1 (and Python 3).

What is the easiest and most reliable way to do this? Do I just
install Weewx again on the same Pi using the procedure for an
initial install of the Debian package? Will it keep the database
and conf files or do I have to save them and put them back when
done? Do I need to do anything with OWFS to work with Python 3?
Should I follow the procedure in installation guide:

Tell your system to trust weewx.com :

wget -qO -http://weewx.com/keys.html  | sudo apt-key add -

For Debian10 and later, use python3:

wget -qO -http://weewx.com/apt/weewx-python3.list  | sudo tee 
/etc/apt/sources.list.d/weewx.list


Basically, how best to upgrade without losing the old data and
keeping things working?

Thanks for any guidance.

[weewx-user] Suggestions on best way to upgrade to 4.1.1

2020-06-19 Thread michael form 
I have Weewx 3.92 running on a Raspberry  Pi3 using One-Wire sensors for 
all measurements via a USB to 1-Wire interface (DS9490). The Pi is running 
Buster and I installed Weewx using the Debian installation package. 
Everything is now working fine and I want to tempt fate by upgrading to 
Weewx 4.1.1 (and Python 3).

What is the easiest and most reliable way to do this? Do I just install 
Weewx again on the same Pi using the procedure for an initial install of 
the Debian package? Will it keep the database and conf files or do I have 
to save them and put them back when done? Do I need to do anything with 
OWFS to work with Python 3? Should I follow the procedure in installation 
guide:

Tell your system to trust weewx.com:

wget -qO - http://weewx.com/keys.html | sudo apt-key add -

For Debian10 and later, use python3:

wget -qO - http://weewx.com/apt/weewx-python3.list | sudo tee 
/etc/apt/sources.list.d/weewx.list


Basically, how best to upgrade without losing the old data and keeping 
things working?

Thanks for any guidance.
