New ethernet gateway errors out on Home Assistant



  • Hardware: Arduino Nano + HR91105A Ethernet shield

    I am taking a stab at setting up a new ethernet gateway via the following sketch (build tutorial). I pick up an IP and can ping but HA displays errors (below the sketch) and does not complete setup (as my wireless only gateway does). Ideas where to look?

    * The MySensors Arduino library handles the wireless radio link and protocol
    * between your home built sensors/actuators and HA controller of choice.
    * The sensors forms a self healing radio network with optional repeaters. Each
    * repeater and gateway builds a routing tables in EEPROM which keeps track of the
    * network topology allowing messages to be routed to nodes.

    * DESCRIPTION
    * The EthernetGateway sends data received from sensors to the ethernet link.
    * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
    *
    * The GW code is designed for Arduino 328p / 16MHz.  ATmega168 does not have enough memory to run this program.
    *
    * LED purposes:
    * - To use the feature, uncomment MY_DEFAULT_xxx_LED_PIN in the sketch below
    * - RX (green) - blink fast on radio message received. In inclusion mode will blink fast only on presentation received
    * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
    * - ERR (red) - fast blink on error during transmission error or receive crc error
    *
    * See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.

  • To me the errors look like you have connected the gateway to your home assistant controller, and that home assistant is configured for a serial gateway.
    Home assistant is processing the debug output as the data it is expecting.
    I think you should check your configuration



  • Thank you for pointing me in the right direction. I working on figuring that out via the home assistant mysensors gateway doc but getting errors. Will follow-up if I can't figure it out.

    @mrhutchinsonmn - i dont know if this can help you but this is my homeassistant configuration with ethernet gateway:

    mysensors:
      gateways:
        - device: '192.168.X.X'

  • Much appreciated!

    This is what I ended up with for a working config:

    automation: !include 'automations.yaml'
    default_config: ~
    group: !include 'groups.yaml'
    scene:  !include 'scenes.yaml'
    script: !include 'scripts.yaml'
    mysensors:
      gateways:
        - device: '/dev/ttyUSB0'
          persistence_file: 'mysensors1.pickle'
        - device: '10.10.1.69'
          persistence_file: 'mysensors2.pickle'
          tcp_port: 5003
      optimistic: false
      persistence: true
      retain: true
      version: '2.3'
    
    


  • During a multiple value assignment, the ValueError: not enough values to unpack occurs when either you have fewer objects to assign than variables, or you have more variables than objects. This error caused by the mismatch between the number of values returned and the number of variables in the assignment statement. This error happened mostly in the case of using python split function. Verify the assignment variables. If the number of assignment variables is greater than the total number of variables, delete the excess variable from the assignment operator. The number of objects returned, as well as the number of variables available are the same.

    To see what line is causing the issue, you could add some debug statements like this:

    if len(line.split()) != "xx":
        print line
    

    This will resolve the value error.
