Home Assistant doesn't connect to MySensors on Arduino MEGA

[mrlele]

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:

// Enable debug prints to serial monitor
#define MY_DEBUG

// Enable and select radio type attached
//#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69

// Enable gateway ethernet module type
#define MY_GATEWAY_W5100

// W5100 Ethernet module SPI enable (optional if using a shield/module that manages SPI_EN signal)
//#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.
//#if !defined(MY_W5100_SPI_EN) && !defined(ARDUINO_ARCH_SAMD)
#define MY_SOFTSPI
#define MY_SOFT_SPI_SCK_PIN 54
#define MY_SOFT_SPI_MISO_PIN 56
#define MY_SOFT_SPI_MOSI_PIN 55
//#endif

// When W5100 is connected we have to move CE/CSN pins for NRF radio
#ifndef MY_RF24_CE_PIN
#define MY_RF24_CE_PIN 5
#endif
#ifndef MY_RF24_CS_PIN
#define MY_RF24_CS_PIN 6
#endif

// Enable UDP communication
//#define MY_USE_UDP  // If using UDP you need to set MY_CONTROLLER_IP_ADDRESS below

// Enable MY_IP_ADDRESS here if you want a static ip address (no DHCP)
#define MY_IP_ADDRESS 192,168,1,70

// If using static ip you can define Gateway and Subnet address as well
#define MY_IP_GATEWAY_ADDRESS 192,168,1,1
#define MY_IP_SUBNET_ADDRESS 255,255,255,0

// Renewal period if using DHCP
//#define MY_IP_RENEWAL_INTERVAL 60000

// The port to keep open on node server mode / or port to contact in client mode
#define MY_PORT 5003

// Controller ip address. Enables client mode (default is "server" mode).
// Also enable this if MY_USE_UDP is used and you want sensor data sent somewhere.
//#define MY_CONTROLLER_IP_ADDRESS 192, 168, 1, 200

// The MAC address can be anything you want but should be unique on your network.
// Newer boards have a MAC address printed on the underside of the PCB, which you can (optionally) use.
// Note that most of the Ardunio examples use  "DEAD BEEF FEED" for the MAC address.
#define MY_MAC_ADDRESS 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED

// Enable inclusion mode
#define MY_INCLUSION_MODE_FEATURE
// Enable Inclusion mode button on gateway
//#define MY_INCLUSION_BUTTON_FEATURE
// Set inclusion mode duration (in seconds)
#define MY_INCLUSION_MODE_DURATION 60
// Digital pin used for inclusion mode button
//#define MY_INCLUSION_MODE_BUTTON_PIN  3

// Set blinking period
#define MY_DEFAULT_LED_BLINK_PERIOD 300

// Flash leds on rx/tx/err
// Uncomment to override default HW configurations
//#define MY_DEFAULT_ERR_LED_PIN 7  // Error led pin
//#define MY_DEFAULT_RX_LED_PIN  8  // Receive led pin
//#define MY_DEFAULT_TX_LED_PIN  9  // Transmit led pin

#if defined(MY_USE_UDP)
#include <EthernetUdp.h>
#endif
#include <Ethernet.h>
#include <MySensors.h>
#include <Bounce2.h>


#define RELAY_PIN  40
#define BUTTON_PIN  8
#define CHILD_ID 2
#define RELAY_ON 1
#define RELAY_OFF 0


Bounce debouncer = Bounce();
bool state = false;
bool initialValueSent = false;

MyMessage msg(CHILD_ID, V_STATUS);

void setup()
{
  pinMode(BUTTON_PIN, INPUT_PULLUP);
  debouncer.attach(BUTTON_PIN);
  debouncer.interval(10);

  // Make sure relays are off when starting up
  digitalWrite(RELAY_PIN, RELAY_OFF);
  pinMode(RELAY_PIN, OUTPUT);
}

void presentation()  {
  sendSketchInfo("Relay+button", "1.0");
  present(CHILD_ID, S_BINARY);
}

void loop()
{
  if (!initialValueSent) {
    Serial.println("Sending initial value");
    delay(500);
    send(msg.set(state?RELAY_ON:RELAY_OFF));
    delay(500);
    Serial.println("Requesting initial value from controller");
    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.
