OK I have installed it, I had to use sudo make install as it complained
that it didn't have permission to created in /opt, but I think it is
installed now, however....
pi@pi4B:~ $ owdir
-bash: owdir: command not found
pi@pi4B:~ $ /opt/owfs/bin/owserver --ver
/opt/owfs/bin/owserver version:
3.2p2
libow version:
3.2p2
pi@pi4B:~ $
Is 3.2p2 the correct version? I thought it should be 3.2p4.
Also I cannot get owdir to work
pi@pi4B:~ $ owdir
-bash: owdir: command not found
pi@pi4B:~ $ /opt/owfs/bin/owdir
pi@pi4B:~ $
I have sensors connected and they were working, have I missed something?
I tried starting the service -
pi@pi4B:~ $ sudo systemctl start owserver
Failed to start owserver.service: Unit owserver.service is masked.
pi@pi4B:~ $ sudo service owserver start
Failed to start owserver.service: Unit owserver.service is masked.

My CRC16 value goes only up by one for setting /simultanous/voltage to '1'
I only tested with setting this once and read the CRC16 back right
away without delay.
Here is my personal notes for installing owfs from github - I hope it
helps you - if you have the code you can of course skip the git-hub part
In this notes I used some special parameters, which you do not have to
use of course, but it illustrates that you have the ability to
influence quite a number of things during configure
additionally, you should not run anything as sudo - especially not
untested patches - so Stefano indicated how to circumvent this easily
with setting a symlink (see last line)
get owfs
git clone git://git.code.sf.net/p/owfs/code owfs-code
then cd into owfs-code
./bootstrap # an error appeared and I had to install packages
# ./bootstrap: 12: ./bootstrap: libtoolize: not found
# aclocal: not found
# pkg-config, libtool, automake
./configure
./configure --disable-swig --prefix=/home/mnm/owfs/
--program-suffix=_test85C
--with-systemdsystemunitdir=/home/mnm/owfs/systemd
make
make install
### no more running with sudo !!! ###
link owserver_<suffix> to dir /usr/bin so it can be found when
executing it with sudo
sudo ls -s /home/mnm/owfs/bin/owserver_<suffix
/usr/bin/owserver_<suffix>

First, I noticed a typo in my mail, the CRC value increases by 8, not
1, when I set /simultaneous/voltage. My code was setting
/temperature then /voltage, I wondered if a delay between them may
help, tried and it did not. I also tried setting /voltage first then
/temperature but it still increased CRC on /voltage.
Yes I do have a voltage device, a DS2437. I only have one, so
setting /simultaneous/voltage is probably not going to save any time,
but it seemed the right way to do it.
I looked at issue 55, don't know if that is related on not. I am
happy to test 3.2p4 but don't know how to do it.
If I download from https://sourceforge.net/projects/owfs/ I get 3.2p1
which is what I was running anyway.
I download the .zip from https://github.com/owfs/owfs unpacked into a
new directory and tried to follow the instructions in INSTALL, this
is what I got -
pi@pi4B:~/owfs/owfs-master $ ls
acinclude.m4 COPYING Makefile.am RELEASE.md
AUTHORS COPYING.LIB man2md release.pl
autom4te.cache debian module src
bootstrap description-pak NEWS TODO
ChangeLog Dockerfile.release README.DEVELOPERS
update_wiki_manpages
configure.ac INSTALL README.md
pi@pi4B:~/owfs/owfs-master $ ./configure
-bash: ./configure: No such file or directory
pi@pi4B:~/owfs/owfs-master $
I ran out of knowledge at this point. If you can tell me how to
install it I will test it out.
Thanks

The CRC16 error could be related to
https://github.com/owfs/owfs/issues/55
The version on master is already patched, and will be released in
3.2p4. If possible check if the current version on master works as
expected.

Mick, do you have voltage devices on your network? (I hope it is
not a stupid question)
I don't have such devices, so I cannot test this further...
Greetings,

I have been doing some more testing and have a couple of issues.
My code sets simultaneous/temperature, waits a couple of seconds
then reads latesttemp from each sensor.
1. Reading latesttemp generally takes 0.07 seconds BUT every 120
seconds every sensor takes 0.75 seconds for a single loop,
then back to 0.07 seconds. (/settings/timeout/presence is set
to 120)
2. My understanding is that simultaneous/voltage works in the
same way, however when I set it my CRC_errors increases by 8.
Why is this?
Cheers
Mick
