Hello
I am trying to get a RP3 to talk to a older Dallas OneWire weather
instrument.
The WeeWx installation works with the simulator and outputs weather reports
but will not start when I use OWFS as the driver in the weewx.conf.
The 1wire is connected to the RP3 via a i2C board and this is working as I
can see data via a browser at localhost:2121
Using the latest build for Raspban.
On restart Weewx reports
