I just upgraded my ISY from 4.x to 5.x and converted from OWLink to NodeLink.  I modified my heartbeat programs to handle the NodeLink 1Wire heartbeat, but can not figure out how to handle sensor errors like what I was doing in OWLink.  Does NodeLink have a similar feature that I'm missing?  The only fields I see for the 1Wire Controller is Heartbeat and Sensor Count.

 

The Error bit in OWLink was redundant to the heartbeat.  The heartbeat only toggled if there is no error.  So in NodeLink I ditched it.  If you get a heartbeat toggle, there are no errors.

Hmmm.  I'm not sure the error bit was redundant.  I was using the heartbeat to let me know if my RPi was still operational, whereas I used the error bit to tell me I might need to replace/fix a 1wire device.  I didn't know the heartbeat stopped if the error bit was set in OWLink.  I'll have to come up with a different solution to indicate that the RPi has lost connection or died.

Thanks for the info io_guy.  And I really appreciate all the work you've done with these projects.
