Thanks Colin, I had forgotten to enable i2c. It all works now.

How are you connecting the devices to the pi?
Have you run raspi-config and enabled/disabled the appropriate sections?
You have to use sudo with systemctl.

I'm trying to install on Raspbian Buster and failing!
I did the usual updates, then installed owserver owhttpd ow-shell, it
has installed 3.2p3
owdir worked, but that was with the fake devices in owfs.conf. Edited
that out and added dtparam=i2c1=on
sudo i2cdetect -y 1
gives me
Error: Could not open file `/dev/i2c-1' or `/dev/i2c/1': No such file or
directory
Searching suggested adding dtparam=i2c1=on to /boot/config.txt
I did that and rebooted
I still get Error: Could not open file `/dev/i2c-1' or `/dev/i2c/1':
No such file or directory
Thought I might need to restart the service but
