    • Which kernel to use?

      Hi,

      I am using my Neuron since a couple of years now and I am still convinced of having a great system.

      I am currently simply a little bit confused if I am on the up-to-date distro and kernel.

      So what I have now is:
      Raspbian GNU/Linux 9 (stretch)
      and

      root@zentrale:/boot# uname -a
      Linux zentrale 4.19.66-v7+ #1253 SMP Thu Aug 15 11:49:46 BST 2019 armv7l GNU/Linux
      

      Am I still up-to date? I am wondering because an apt upgrade complained about some missing linux-header files for version 4.19.66-v7+.

      Is there something missing? I do not dare to reboot currently :\

      Thanks

    • Experiences with openHAB?

      Hi all,

      I am looking for a control unit for my upcoming smart hone.As I already have a M103 running for my heating (coded it on my own based on C) I prefer to use it for the control unit for smart home.

      I was thinking of using openHAB as it appears to be the most active and stable way for such a unit (tried with NodeRed but this looks really complicated for me) Some years ago I did some first steps in FHEM - I could imagine to get it running...

      Anyway, anyone here who has some experience with openHAB on a Neuron device?

      Thanks!

    • Build-In 1Wire does not work!

      Hi all,

      I have a Neuron M103 which has USB and a 1-wire interface.

      When I connect my sensors to the build-in port I do not find them. Connecting through a USB adapter works flawlessly!

      Any idea?
      I changed /etc/owfs.conf according to the device I am using. Disabled the FAKE device and tried to enable the i2c:

      #server: FAKE = DS18S20,DS2405
      
      # Setting for Neuron M103 
      server: device = /dev/i2c-1
      #
      # USB device: DS9490
      #server: usb = all
      

      Now when I do i2cdetect -l I get the correct one I used in above owfs.conf:

      i2c-1   i2c             bcm2835 I2C adapter                     I2C adapter
      

      Seems to be the bus is recognized properly:

      root@zentrale:/heizung/src# i2cdetect -y 1
           0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
      00:          -- -- -- -- -- -- -- -- -- -- -- -- --
      10: -- -- -- -- -- -- -- -- 18 -- -- -- -- -- -- --
      20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
      30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
      40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
      50: -- -- -- -- -- -- -- UU -- -- -- -- -- -- -- --
      60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- UU
      70: -- -- -- -- -- -- -- --
      

      Changing the device to i2c-1 in owfs.conf, restarting owfs and switching cable to Neuron port I do not get any device:

      root@zentrale:/heizung/src# owdir
      /bus.0
      /uncached
      /settings
      /system
      /statistics
      /structure
      /simultaneous
      /alarm
      

      Switching everything back to USB I get proper information:

      root@zentrale:/heizung/src# owdir
      /10.A224A3010800
      /10.520F86010800

      /settings
      /system
      /statistics
      /structure
      /simultaneous
      /alarm
      

      Any idea how to use the build-in i2c-1-wire-bus?

    • RE: Latest Update: Issues with unipi_tcp_server and unipispi

      Hi,

      I fixed it by
      apt install neuron-kernel

      It uninstalled dmks modules- I am unsure if this is a proper solution. At least it seems to work now.

      Greetings

    • Latest Update: Issues with unipi_tcp_server and unipispi

      Hi,

      since the latest update (unipi-kernel-modules-dkms 1.36) I am having issues with my Neuron M103.

      Starting the tcp-server manually results in an error about /dev/unipispi:

      root@zentrale:/heizung/src# /opt/unipi/tools/unipi_tcp_server -p 502 -l 0.0.0.0  --verbose --check-firmware
      ARMINIT: Cannot open device /dev/unipispi
      ARMINIT: Cannot open device /dev/unipispi
      ARMINIT: Cannot open device /dev/unipispi
      UniPi TCP Modbus Server: Listening Connection Established RET:3
      poll timeout = -1[ms]
      Starting primary loop
      

      When trying to access through modbus I get an error:
      fieldbus_get_ai error: Slave device or server failure

      So looks like I can not open unipispi device. Modules seems to be loaded:

      root@zentrale:/heizung/src# lsmod| grep unipi
      rtc_unipi              16384  0
      root@zentrale:/heizung/src# lsmod| grep spi
      spidev                 20480  0
      spi_bcm2835            20480  0
      

      Anyone having a clue how to deal with this issue?

      Thanks a lot!
