Error sending switch command at Gateway



  • Hello All...
    I am having a problem with sending a 4 relay block code to Domoticz Gateway … sometimes the relays switch without any problem, but other times, it breaks out to an "Error sending switch command".

    I saw an earlier post at https://forum.mysensors.org/topic/4658/solved-error-sending-switch-command with the same issue. The solution proffered there didn't have much impart. One second it's working fine and the next its breaking into errors.

    I couldn't find a .1uf Capacitor, so I used an electrolytic 1uf instead. Worked fine in another Nfr+ radio Project, but I don't know if that's the problem here. My sketch is a follows:-

    // Example sketch showing how to control physical relays. 
    // This example will remember relay state even after power failure.
    
    // Enable debug prints
    #define MY_DEBUG
    
    // Enable and select radio type attached
    #define MY_RADIO_NRF24
    
    #define MY_NODE_ID 6  // Set this to fix your Radio ID or use AUTO or 1
    #define MY_REGISTRATION_FEATURE // Forece registration
    #define MY_REGISTRATION_RETRIES 5
    
    #include <Wire.h>
    #include <TimeLib.h>
    #include <SPI.h>
    #include <MySensors.h>
    #include <LCD.h>
    #include <LiquidCrystal.h>
    #include <LiquidCrystal_I2C.h>
    
    // For Debug
    #ifdef DEBUG_ON
    #define DEBUG_PRINT(x)   Serial.print(x)
    #define DEBUG_PRINTLN(x) Serial.println(x)
    #else
    #define DEBUG_PRINT(x)
    #define DEBUG_PRINTLN(x)
    #define SERIAL_START(x)
    #endif
    
    #define RELAY_PIN 2  // Arduino Digital I/O pin number for first relay (second on pin+1 etc)
    #define NUMBER_OF_RELAYS 4 // Total number of attached relays
    #define RELAY_ON 0  // GPIO value to write to turn on attached relay
    #define RELAY_OFF 1 // GPIO value to write to turn off attached relay
    #define SKETCH_NAME "Swimming Pool Node"
    #define SKETCH_VERSION "0.1.4"
    #define CHILD_ID 0
    
    MyMessage msg(1,V_LIGHT);
    unsigned long SLEEP_TIME = 5000;   // Sleep time inbetween reads in milliseconds
    void setup()
    {
      for (int sensor=1, pin=RELAY_PIN; sensor<=NUMBER_OF_RELAYS; sensor++, pin++) {
        // Then set relay pins in output mode
        pinMode(pin, OUTPUT);
        // Set relay to last known state (using eeprom storage)
    //    digitalWrite(pin, loadState(sensor)?RELAY_ON:RELAY_OFF);   // to remember last state
        digitalWrite(pin, loadState? 0 : 0);   // Keep everything off after power failure
      }
    }
    
    void presentation() { 
      sendSketchInfo(SKETCH_NAME, SKETCH_VERSION);
    
      // Fetch relay status
      for (int sensor=1, pin=RELAY_PIN; sensor<=NUMBER_OF_RELAYS; sensor++, pin++) {
        // Register all sensors to gw (they will be created as child devices)
        present(sensor, S_BINARY);
        pinMode(pin, OUTPUT); // Then set relay pins in output mode  
    //    boolean savedState = loadState(sensor); // Set relay to last known state (using eeprom storage)
    //    digitalWrite(pin, savedState?RELAY_ON:RELAY_OFF);
    //    send(msg.set(savedState? 0 : 1));
      }
          DEBUG_PRINTLN(F("Sensor Presentation Complete"));
    }
    void loop() 
    {
    // Alway process incoming messages whenever possible
    // Sleep until interrupt comes in on motion sensor. Send update every two minute.
    //  sleep(digitalPinToInterrupt(msg.sensor-1+RELAY_PIN), CHANGE, SLEEP_TIME);
    wait(SLEEP_TIME);
    }
    void receive(const MyMessage &message){
    // Change relay state if message is receieved
    
       if (message.type == V_STATUS){
       digitalWrite(message.sensor-1+RELAY_PIN, message.getBool()?RELAY_ON:RELAY_OFF);
    // Store state in eeprom
       saveState(message.sensor-1+RELAY_PIN, message.getBool());
    // Write some debug info
       Serial.print("Incoming change for sensor ID: ");
       Serial.print(message.sensor);
       Serial.print(", New status: ");
       Serial.println(message.getBool());
        } 
      }
    

    I hear tagging this trio solves problems, so here goes... @tekka, @kk02067 and @hek to help me with this one. So sorry guys.
