Markus,
Good point. In my case the "client" would be openremote, as it supports
1-wire communications directly to the owserver to retrieve values. There
isn't any way to specify options that i can figure out in their designer
when building the command or sensor.
I suppose the way to accomplish this would be to use the HTTP command and
parse the webpage response from owhttpd (which is in F) and pull out the
temp that way. That might be beyond my regular expression ability since
every attempts keeps matching some other page element.
Thanks,
pete
