Hi Paul, Thanks for you help (again!!)
I have it working now but I am still somewhat confused. As far as I can see the problem was that I started owfs with /opt/owfs/bin/owfs -s localhost:3001 -m -a /home/share/solar/sensor_list4.1 /var/1-wire/mnt which looks a bit odd having '-m' followed by '-a'. I have now changed this to /opt/owfs/bin/owfs -s localhost:4304 -a /home/share/solar/sensor_list4.1 -m /var/1-wire/mnt and it all works! I would have expected none of it to work with my original format but owfs was working fine. One other question, to make my system a bit more robust it looks through the ports to find the one with the 1-wire network by looking at the number of directory entries in the mounted directory, should be more than 7 for a valid network. During testing I found that this was failing and eventually discovered that I needed a delay between issuing the owfs command and reading the directory. I don't like using pauses to fix problems like that, is there some way to see if owfs is started correctly?
