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. pi@pi4B:~ $ On 16/08/2020 21:46, Martin Patzak wrote: > 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> > > > On 16.08.20 21:59, Mick Sulley wrote: >> >> First, I noticed a typo in my mail, the CRC value increases by 8, not >> 1, when I set /simultaneous/voltage.
