Hello everyone, I would need a Sketch with 4 magnetic door sensors, 2 relays and 1 ds18b20.

Fit a sketch found on the net, for mysensor

Sensor DHT-11

relay with button and without gateway, and sensor air and humidity.
How do I insert the temperature sensor skech, within this:

#define MY_DEBUG                               // Enable debug prints to serial monitor

#define MY_RADIO_NRF24                         // Enable and select radio type attached
#define MY_NODE_ID 8


#define MY_TRANSPORT_WAIT_READY_MS 5000        //set how long to wait for transport ready in milliseconds

#include <MySensors.h>
#include <Bounce2.h>

#define RELAY_PIN  4      // Arduino Digital I/O pin number for relay 
#define BUTTON_PIN  3     // Arduino Digital I/O pin number for button 
#define CHILD_ID 1        // Id of the sensor child
#define RELAY_ON 0
#define RELAY_OFF 1

Bounce debouncer = Bounce();
int oldValue = 0;
bool uplinkAvailable = true;
bool state = false;
bool requestState;
bool firstStart = true;
unsigned long uplinkCheckTime ;                // holder for uplink checks
unsigned long uplinkCheckPeriod = 30*1000;     // time between checks for uplink in milliseconds
unsigned long returnWait = 1500;               // how long to wait for return from controller in milliseconds
MyMessage msg(CHILD_ID, V_STATUS);

void setup(){
  pinMode(BUTTON_PIN, INPUT_PULLUP);           // Setup the button pin, Activate internal pull-up
  
  debouncer.attach(BUTTON_PIN);                // After setting up the button, setup debouncer
  debouncer.interval(5);

  pinMode(RELAY_PIN, OUTPUT);                 // set relay pin in output mode
  digitalWrite(RELAY_PIN, RELAY_OFF);         // Make sure relay is off when starting up
}

  // Register all sensors to gw (they will be created as child devices)

      if (requestState != state) {           // check that controller is corectly showing the current relay state
        send(msg.set(state), false);         // notify controller of current state
      }
    }
    else {

      uplinkAvailable = false;               // no uplink established

    }
    firstStart = false;                     // set firstStart flag false to prevent code from running again
  }

  debouncer.update();
  int value = debouncer.read();                               // Get the update value

It's too long.

How do I send it to you? It's too long.

But should I use watchdog? To reset nodes automatically every day?

I understand, but the only sensors that connect are: The temperature sensor and the gas sensor, which send periodic signals. My system is structured on 3 floors. The first floor has the Gateway, and off the first floor has a Node Repeater. Then the second floor has another Node Repeater and has 2 Relay Nodes. And finally the Third Floor with another repeater and 2 sensors, Gas and Temp / Hum.

Hi everyone, I wanted to know how ever whenever the PC reboots, I also change the com port. And why when I break the gateway, are the sensors no longer connected? It's okay to restart them all to let them read.

Hi I combined the sketch of a door sensor to adapt it to a photoresist and added a relay. The relay in question only works once and then freezes everything.

// We only expect one type of message from controller. But we better check anyway.

Can someone help me?

I followed the Mq2 Sensor Tutorial, but I'm only out of the kids and not on devices. Instead, for the rain sensor I did not find anything.

Hi everyone, I have two sensors I can not configure them in Domoticz.
Mq2 gpl and rain sensor Mhrd. How can I do?
