    • RE: 💬 Temperature Sensor

      @gohan Thanks for the quick reply! Well I've use the standard sketch for this Temperatur sensor. This is the code i've got.

      // Enable debug prints to serial monitor
      //#define MY_DEBUG 
      
      // Enable and select radio type attached
      #define MY_RADIO_NRF24
      //#define MY_RADIO_RFM69
      
      #include <SPI.h>
      #include <MySensors.h>  
      #include <DallasTemperature.h>
      #include <OneWire.h>
      
      #define COMPARE_TEMP 1 // Send temperature only if changed? 1 = Yes 0 = No
      
      #define ONE_WIRE_BUS 3 // Pin where dallase sensor is connected 
      #define MAX_ATTACHED_DS18B20 16
      unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds)
      OneWire oneWire(ONE_WIRE_BUS); // Setup a oneWire instance to communicate with any OneWire devices (not just Maxim/Dallas temperature ICs)
      DallasTemperature sensors(&oneWire); // Pass the oneWire reference to Dallas Temperature. 
      float lastTemperature[MAX_ATTACHED_DS18B20];
      int numSensors=0;
      bool receivedConfig = false;
      bool metric = true;
      // Initialize temperature message
      MyMessage msg(0,V_TEMP);
      
      void before()
      {
        // Startup up the OneWire library
        sensors.begin();
      }
      
      void setup()  
      { 
        // requestTemperatures() will not block current thread
        sensors.setWaitForConversion(false);
      }
      
      void presentation() {
        // Send the sketch version information to the gateway and Controller
        sendSketchInfo("Temperature Sensor", "1.1");
      
        // Fetch the number of attached temperature sensors  
        numSensors = sensors.getDeviceCount();
      
        // Present all sensors to controller
        for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {   
           present(i, S_TEMP);
        }
      }
      
      void loop()     
      {     
        // Fetch temperatures from Dallas sensors
        sensors.requestTemperatures();
      
        // query conversion time and sleep until conversion completed
        int16_t conversionTime = sensors.millisToWaitForConversion(sensors.getResolution());
        // sleep() call can be replaced by wait() call if node need to process incoming messages (or if node is repeater)
        sleep(conversionTime);
      
        // Read temperatures and send them to controller 
        for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {
      
          // Fetch and round temperature to one decimal
          float temperature = static_cast<float>(static_cast<int>((getControllerConfig().isMetric?sensors.getTempCByIndex(i):sensors.getTempFByIndex(i)) * 10.)) / 10.;
      
          // Only send data if temperature has changed and no error
          #if COMPARE_TEMP == 1
          if (lastTemperature[i] != temperature && temperature != -127.00 && temperature != 85.00) {
          #else
          if (temperature != -127.00 && temperature != 85.00) {
          #endif
      
            // Send in the new temperature
            send(msg.setSensor(i).set(temperature,1));
            // Save new temperatures for next compare
            lastTemperature[i]=temperature;
          }
        }
        sleep(SLEEP_TIME);
      }```

    • RE: 💬 Temperature Sensor

      @gohan No I have not. I have a RF-Link also connected to the HA and it's working great. As I said, if I use the same hardware that I used to control the Dallas sensor and change the sensor to a DHT sensor the DHT sensor is accepted by HA and shows up as a sensor. That's why I was asking if there is something in the code for the Temperature sensor sketch that has to be changed to be able to present it to HA.

    • RE: 💬 Temperature Sensor

      Hi, I'm having a hard time getting this Temperatursensor to work with Home Assistant. When i start it it doesn't register with the HA. If I use the same hardware and switch out the sensor to a DHT sensor (new sketch of course) then it works out of the box, HA sees the sensor. I've tried changing the Dallas DS18B20, but nothing. If i look at the logs the gateway have no problem with the sensor. Is there something in the code for the sensor that doesn't add up to it being presented to HA in the right way? I'm quite the newbie when it comes to programming.
