I am still in the process of converting my existing software, there have
been many changes and even with the best intentions I don't think I have
recorded them all, so once it is all sorted I intend to start again with
a blank SD card, set it all up from scratch and make sure that I have a
record of everything that I have done. It is not just owfs, there are
several other components as well, but I will share the results when
complete.
One thing I have found following the mails from Stefano an Jan -
$ ls -l /dev/i2c-1
crw-rw---- 1 root i2c 89, 1 Aug 31 21:38 /dev/i2c-1
$ sudo systemctl status owserver.service
● owserver.service - Backend server for 1-wire control
Loaded: loaded (/lib/systemd/system/owserver.service; enabled)
Active: inactive (dead)
Docs: man:owserver(1)
My user was not a member of the i2c group so I added it and rebooted,
now get
$ sudo systemctl status owserver.service
[sudo] password for control:
● owserver.service - Backend server for 1-wire control
Loaded: loaded (/lib/systemd/system/owserver.service; enabled)
Active: active (running) since Thu 2016-09-01 09:39:46 BST; 10min ago

└─1297 /opt/owfs/bin/owserver --w1
Sep 01 09:39:46 pi-solar systemd[1]: Started Backend server for 1-wire

Hint: Some lines were ellipsized, use -l to show in full.
which looks much better! My work continues.......

This sounds a lot like my problem with raspbian... which I've still
not sorted.

Sounds a lot like permission problems.
First, which distro are you using? I will assume you are on
raspbian/jessie, but let us know if this is not true.
Debian/jessie is systemd based, so please forget about “service XXX
start|stop|restart” and use “systemctl start|stop|restart XXX.service”

Try these commands (as root or with sudo) and see if systemctl
records some useful info with
*$*sudo journalctl -u owserver.service
Hope this helps
S.
PS:
I just noticed that the LSB scripts in raspbian/jessie are bugged:
they return with a success status even if owserver failed to start…
So do not trust to much systemctl status, but always check if the
owserver process is really running.
