[Owfs-developers] Unable to retrieve "temperature" reading

[Jim R. <jim...@li...>]

Hi,

 

I have a OWFS 3.1p0 compiled on a Windows Server 2012 x64 using Cygwin.
OWSERVER is running and with OWHTTPD running and connected.  I am able to
browse my devices using OWHTTPD and see settings and temperature readings as
normal.  I am also able to do this remotely (over a VPN).  So the server
part appears to be operating normally.

 

However, I am trying to develop a small application using Visual Studio and
the OWNET C# library provided by Viktor Vorobjov
(https://github.com/straga/owfs.ownet).  So far my application connects
fine, and I can read all of the directories:

 

OUTPUT:

81.14D52D000000

1F.746205000000

1F.826205000000

1F.1A6305000000

1F.1D6305000000

1F.0F6305000000

1F.6F6205000000

bus.0

uncached

settings

system

statistics

structure

 

As well, I'm able to read many variables from different devices with no
problems.  However, when I try to read a temperature, the return value is
NULL:

 

READ:

Path="/1F.0F6305000000/aux/28.CBEDC8010000/temperature"

Persistance support: False)] :

I've tried modifying various parameters (DataLen, Persistance, Timeout) and
using "uncached" with no success.

 

I know that C# is not part of this project but I seem to remember having the
same issue when messing around with the OWNET.py code.

 

Any ideas?

 

Thanks.
