Home Assistant doesn't connect to MySensors on Arduino MEGA



  • Hello,
    it's the first time that I'm using MySensors (on Arduino MEGA) with Home Assistant (on Raspberry Pi 3) and I really don't understand why this two devices don't talk with each other.

    I have upload this simple scatch on Arduino:

    #define MY_DEBUG

    //#define MY_W5100_SPI_EN 4
    
    // Enable Soft SPI for NRF radio (note different radio wiring is required)
    // The W5100 ethernet module seems to have a hard time co-operate with
    // radio on the same spi bus.

    // The MAC address can be anything you want but should be unique on your network.

    Bounce debouncer = Bounce();

    }
    
    void loop()

        delay(500);
        request(CHILD_ID, V_STATUS);
        wait(4000, C_SET, V_STATUS);
      }
      if (debouncer.update()) {
        if (debouncer.read()==LOW) {
          state = !state;
          // Send new state and request ack back
          send(msg.set(state?RELAY_ON:RELAY_OFF), true);
        }
      }
    }
    
    void receive(const MyMessage &message) {
      
      Serial.println(message.type);
      delay(500);
      
      if (message.isAck()) {
         Serial.println("This is an ack from gateway");
      }
    
      if (message.type == V_STATUS) {
        if (!initialValueSent) {
          Serial.println("Receiving initial value from controller");
          initialValueSent = true;
        }
        // Change relay state
        state = (bool)message.getInt();
        digitalWrite(RELAY_PIN, state?RELAY_ON:RELAY_OFF);
        send(msg.set(state?RELAY_ON:RELAY_OFF));
      }
    }
    

    Debug output is this one:

    IP: 192.168.1.70
    0;255;3;0;9;MCO:BGN:STP
    0;255;3;0;9;MCO:REG:NOT NEEDED
    0;255;3;0;9;MCO:BGN:INIT OK,TSP=NA
    Sending initial value
    0;255;3;0;9;MCO:BGN:INIT GW,CP=R-NGA--,VER=2.1.1
    

    It is showed every 2 sec. in Arduino Serial Panel.

    On the other side I have writen this configuration in "configuration.yaml":

    mysensors:
      gateways:
        - device: '192.168.1.70'      
          persistence_file: 'mysensors.json'
          tcp_port: 5003    
      optimistic: false  
      persistence: true
      retain: true
      version: 2.0
    

    but Home Assitant log show me this messages:

    2017-09-07 13:43:20 ERROR (Thread-2) [mysensors.gateway_tcp] Receive from server failed. 
    2017-09-07 13:43:20 ERROR (Thread-2) [mysensors.gateway_tcp] Failed to shutdown socket at ('192.168.1.70', 5003)
    

    So what I can do?
    Thanks to all.

    Edit:
    I've enabled debug on Home Assistant and it show me this:

    Can you connect to the gateway using myscontroller?

    My guess is that the arduino gateway reboots every two seconds, either due to a bug in the core arduino library or due to low power availability when sending from the radio.
