I am trying the GPIO method, wired as suggested.
Have tried a waterproof DS18B20 and a DS18b20 IC.
I hoped to see a family 28 device but both devices give this:
pi@rpiD /weather $ sudo ls -l 1wire
total 0
drwxrwxrwx 1 root root 8 Jun 14 16:08 05.4AEC29CDBAAB
drwxrwxrwx 1 root root 8 Jun 14 16:08 10.67C6697351FF
drwxr-xr-x 1 root root 8 Jun 14 15:21 alarm
drwxr-xr-x 1 root root 8 Jun 14 15:21 bus.0
drwxr-xr-x 1 root root 8 Jun 14 15:21 bus.1
drwxr-xr-x 1 root root 8 Jun 14 15:21 settings
drwxrwxrwx 1 root root 8 Jun 14 16:08 simultaneous
drwxr-xr-x 1 root root 8 Jun 14 15:21 statistics
drwxr-xr-x 1 root root 32 Jun 14 15:21 structure
drwxr-xr-x 1 root root 8 Jun 14 15:21 system
drwxr-xr-x 1 root root 8 Jun 14 15:21 uncached
Where are the 05 and 10 devices coming from?
Thanks,
Peter
P.S.
Is the best owfs documentation the man pages?

What NetFlow Analyzer can do for you? Monitors network bandwidth and traffic
patterns at an interface-level. Reveals which users, apps, and protocols are
consuming the most bandwidth. Provides multi-vendor support for NetFlow,
J-Flow, sFlow and other flows. Make informed decisions using capacity
planning reports. https://ad.doubleclick.net/ddm/clk/305295220;132659582;e
