Node request temperature from gateway

Daniel Rus

Hi guys,

I am trying for the last days to make the gateway to send data to node.
Till now i dont have any luck , i am using an Arduino Nano for the node and and Arduino Mega with Ethernet adapter.
Below is my gateway code:


#define MY_RADIO_NRF24
#define MY_RF24_CE_PIN 6
#define MY_RF24_CS_PIN 4
#define MY_SOFTSPI
#define MY_GATEWAY_SERIAL
#include <SPI.h>
#include <MySensors.h>
#define CHILD_ID 4   // Id of the sensor child
MyMessage msg(CHILD_ID, V_TEMP);

void setup()
{  }

void presentation()  {
  present(CHILD_ID, S_TEMP);
}

void loop()
{ float temperature = 99; // dht.getTemperature();
  send(msg.set(temperature, 1));

}

void receive(const MyMessage &message) {

}

and the code for the node is :


#include <SPI.h>
#define MY_RADIO_NRF24
#define MY_RF24_CE_PIN 10
#define MY_RF24_CS_PIN 9
#define MY_NODE_ID 2
#include <MySensors.h>

void setup()
}
void presentation()
{
}

void loop()
{ request(4, V_TEMP, 0);
}

void incomingMessage(const MyMessage &message) {
  if (message.type == V_TEMP) {
    Serial.print("Incoming change for sensor:");
    Serial.print(message.sensor);
    Serial.print("\n");
    Serial.print(", New status: ");
    Serial.println(message.getFloat());

  }
}

The serial from the node:

0;4;1;0;0;99.0
2;4;2;0;0;
2;4;2;0;0;
0;4;1;0;0;99.0
2;4;2;0;0;
2;4;2;0;0;
0;4;1;0;0;99.0
2;4;2;0;0;
0;4;1;0;0;99.0
0;4;1;0;0;99.0
2;4;2;0;0;
0;4;1;0;0;99.0

In the serial from the node with debug activated:

Welcome to the MySensors community @daniel-rus

A gateway does not store any data. You need to use a controller. It looks like there is no controller in your system?

If you haven’t already, see https://www.mysensors.org/about/network for an overview of how MySensors works.

@mfalkvidd Hi, I manage to make an MQTT gateway with home assistant as controller .
The serial from gateway i can see that the gateway send data out from MQTT, but the node still not receive anything
