    Very nice write up! Next add some current sensing ability to see what your load is pulling. :) Although if used for lighting, mostly negligible I suppose haha.

    A non invasive sensor would be ideal. I alredy use energimonitor for solar panels!!!!!

      Bello GiGi! Nice GiGi.

      If you want pm me as I understand we are from the same country.
      May be we can exchange some experience in italian ;-)
      Will copy your design

          if we put this box in wall then power supply will safe or not?

          5v power supply adapter's temperature will afact or not?

                You seem to have downloaded the development branch of the MySensors library. The code you're trying to run is 1.5.

                  I downloaded this , https://github.com/mysensors/Arduino . I Submitted libraries entirely within the zip file in my briefcase Arduino library.
                  however it from the library is the 1.5 readme. Where am I wrong ?
                  il codice è il seguente

                  #include <MySensor.h>
                  
                  #include <SPI.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 1
                  #define RELAY_OFF 0
                  
                  Bounce debouncer = Bounce();
                  int oldValue=0;
                  bool state;
                  MySensor gw;
                  MyMessage msg(CHILD_ID,V_LIGHT);
                  
                  void setup()
                  {
                  gw.begin(incomingMessage, AUTO, true);
                  
                  // Send the sketch version information to the gateway and Controller
                  gw.sendSketchInfo("Relay & Button", "1.0");
                  
                  // Setup the button
                  pinMode(BUTTON_PIN,INPUT);
                  // Activate internal pull-up
                  digitalWrite(BUTTON_PIN,HIGH);
                  
                  // After setting up the button, setup debouncer
                  debouncer.attach(BUTTON_PIN);
                  debouncer.interval(5);
                  
                  // Register all sensors to gw (they will be created as child devices)
                  gw.present(CHILD_ID, S_LIGHT);
                  
                  // Make sure relays are off when starting up
                  digitalWrite(RELAY_PIN, RELAY_OFF);
                  // Then set relay pins in output mode
                  pinMode(RELAY_PIN, OUTPUT);

                  state = gw.loadState(CHILD_ID);
                  digitalWrite(RELAY_PIN, state?RELAY_ON:RELAY_OFF);
                  }
                  /*
                  * Example on how to asynchronously check for new messages from gw

                  void loop()
                  {
                  gw.process();
                  debouncer.update();
                  // Get the update value
                  int value = debouncer.read();
                  if (value != oldValue && value==0) {
                  gw.send(msg.set(state?false:true), true); // Send new state and request ack back
                  }
                  oldValue = value;
                  }
                  
                  void incomingMessage(const MyMessage &message) {
                  // We only expect one type of message from controller. But we better check anyway.
                  if (message.isAck()) {
                  Serial.println("This is an ack from gateway");
                  }
                  
                  if (message.type == V_LIGHT) {
                  // Change relay state
                  state = message.getBool();
                  digitalWrite(RELAY_PIN, state?RELAY_ON:RELAY_OFF);
                  // Store state in eeprom

                  // Write some debug info
                  Serial.print("Incoming change for sensor:");
                  Serial.print(message.sensor);
                  Serial.print(", New status: ");
                  Serial.println(message.getBool());
                  }
                  }```

                        Here is the improved code that I used on my Arduino Mega to create a home automation controller

                        New optimized code to arduino mega

                          Update: Forget it, the code works with Arduino Mini and 2 relay. I tried one after the code of Arduino Mega and not working. Something wrong but I do not know what I require help
                          picture.jpg

                          I found mistakes on Arduino Mega solvable at the following link
                          http://forum.mysensors.org/topic/2161/the-mysensor-1-5-code-is-not-compiling-for-my-arduino-mega-2560-board/1
                          but I do not have this kind of problem you can get support? I connected NRF24L01 to Arduino Mega, as if it were an Arduino Nano, right?

                            The SPI pins has different pin numbers on the Mega.

                            Here is an example that runs the the Mega:

                              I connected the radio module as follows

                              AtMega 2650 Arduino Step Down Module/Radio
                              GND > GND

                              I tried but it did not work I tried to connect also IrQ
                              2 > IRQ
                              it did not work. I tried to connect to 3v3 with the capacitor. it did not work. I tried adding the line in the code
                              #include <MyTransportNRF24.h>
                              #include <MyHwATMega328.h>
                              but to no avail. I am groping in the dark

                                  I have "check wires" error on the serial arduino....
                                  where do I fit in debug mode there is a guide?
                                  I saw a video that uses MQTT program on mac.
                                  I have downloaded windows MYSController I can be of help? How do I connect my PC? It is all new and are a little confused. :dizzy_face: :u7a7a:

                                  I "atmega adk" is a problem?

                                    Have you defined using softspi since using those pins?

                                    I'm using different pins with mega and everything started to work after adding capacitor to radio:
                                    GND > GND
