    • RE: Trouble sending message to Relay from Openhab

      @CJ-Cassarino Thanks for the reply. I will try your send syntax in my Arduino rules. Also, the reason you don't see the mqtt tag is that I am using a Serial Gateway not a MQTT gateway.

    • Trouble sending message to Relay from Openhab

      Simply put I am trying to send a message from Openhab to a MySensors sensor via a Serial Gateway.

      My environment is Openhab 1.7 running on RPi 3. I have a stock Serial Gateway running on Nano using RF24. I have two sensors DHT and micro switch sending data to the gateway and values are appearing in Openhab fine. For about week now I have been trying to turn the communication around. In Openhab I have configured an Switch Item called Relay. When it changes from Off to On I have a rule to send a command to the Arduino gateway item. However the message never shows up on the sensor. Any advice would be appreciated.

      Here is some of the code, config, and logs:

      Relay Sensor:

      #include <EEPROM.h>
      #include <MySigningNone.h>
      #include <MyTransportNRF24.h>
      #include <MyTransportRFM69.h>
      #include <MyHwATMega328.h>
      #include <MySensor.h>
      #include <SPI.h>
      
      #define RELAY_1  3  // Arduino Digital I/O pin number for first relay (second on pin+1 etc)
      #define NUMBER_OF_RELAYS 1 // Total number of attached relays
      #define RELAY_ON 1  // GPIO value to write to turn on attached relay
      #define RELAY_OFF 0 // GPIO value to write to turn off attached relay
      
      // NRFRF24L01 radio driver (set low transmit power by default) 
      MyTransportNRF24 radio(RF24_CE_PIN, RF24_CS_PIN, RF24_PA_LEVEL_GW);  
      //MyTransportRFM69 radio;
      // Message signing driver (none default)
      //MySigningNone signer;
      // Select AtMega328 hardware profile
      MyHwATMega328 hw;
      // Construct MySensors library
      MySensor gw(radio, hw);
      
      void setup()  
      {   
        //Wipe eprom
        for (int i = 0 ; i < EEPROM.length() ; i++) {
          EEPROM.write(i, 0);
        }
        
        // Initialize library and add callback for incoming messages
        gw.begin(incomingMessage, 105, true);
        // Send the sketch version information to the gateway and Controller
        gw.sendSketchInfo("Relay", "1.0");
      
        // Fetch relay status
        for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS;sensor++, pin++) {
          // Register all sensors to gw (they will be created as child devices)
          gw.present(sensor, S_LIGHT);
          // Then set relay pins in output mode
          pinMode(pin, OUTPUT);   
          // Set relay to last known state (using eeprom storage) 
          digitalWrite(pin, gw.loadState(sensor)?RELAY_ON:RELAY_OFF);
        }
      }
      
      
      void loop() 
      {
        // Alway process incoming messages whenever possible
        gw.process();
      }
      
      void incomingMessage(const MyMessage &message) {
        Serial.println("message received");
      
      }
