1wire and 4R-4DI setup problem



  • Hi,

    I'm loving the PI and the addons! I have 2 1wire temp probes working, and an EMO-R8 with my Unipi.

    but I cannot get the 1w-4r-4di working.

    When powered up, it shows 1 green led bright beside the power supply. No other lights, ever.

    To config, i've uncommented the lines in the /etc/evoc.conf file, renamed the relays to start at number 17 upwards (as I already have 16…) and restarted the service.

    I think my cable is ok as I have 2 cables, and can use either one between the unipi and the 8way 1wire hub, and from there to the 1w-4r-4di. The temp sensors connected to the 8way 1wire hub work fine.

  • Have you also configured the address of the board?



  • No, Are they unique? I was using the one in the example file….

    how do I find my boards address?

    (Feeling pretty stupid around about now....)



  • I was looking at this screen: http://0.0.0.0/rest/all

    and the address for the temp probes shows up, as well as the same address as the example file. BUT: I just noticed an address for the unit.

    All working now, Many thanks!
