    • RE: Node 0 unknown, error decoding message from gateway

      @martinhjelmare thank you so much for your help. 🙂

      Is there a way to declare sensor names so that HA receives a presentation with something like

      mysensors.livingroom.temp

      Instead of a more cryptic name with node_id?

      Just saw that myself. Thanks once again. I'm starting to feel embarrassed... 🙂

    • RE: Binary sensor for production counting transmits false values

      @rejoe2 Thanks, I actually have a counter but removed it from the code to keep it simple. It counts the pulses and sends the number for comparison and it matches actually. So the problem is at the beginning with the node "getting false pulses" from the machine. Any idea how that can be explained? 😞

    • RE: Binary sensor for production counting transmits false values

      Thanks for your response. You are perfectly right. The counting happens on the server (counting the transmitted '1's coming via MQTT).

    • Binary sensor for production counting transmits false values

      Hey guys,

      I am currently working on a project in our company where I would like to use NodeMCU to count produced parts and send the data via MQTT. The NodeMCU is attached to one of the pulse generators (e.g. a cutter or welder) and the NodeMCU receives that signal but it seems like it is counting too many signals (like doubling the real value) and I cannot figure out why.

      The highes frequency of pulses (produced parts) I have to deal with are about 2 - 3 per second.

      This is my simple binary sketch:

      // Enable debug prints to serial monitor
      #define MY_DEBUG
      
      // Use a bit lower baudrate for serial prints on ESP8266 than default in MyConfig.h
      #define MY_BAUD_RATE 9600
      
      #define MY_GATEWAY_MQTT_CLIENT
      #define MY_GATEWAY_ESP8266
      
      #define MCU_ID redacted
      
      // Set MQTT client id
      #define MY_MQTT_CLIENT_ID MCU_ID
      
      // Set this node's subscribe and publish topic prefix
      #define MY_MQTT_PUBLISH_TOPIC_PREFIX redacted
      #define MY_MQTT_SUBSCRIBE_TOPIC_PREFIX redacted
      
      // Enable these if your MQTT broker requires username/password
      #define MY_MQTT_USER redacted
      #define MY_MQTT_PASSWORD redacted
      
      // Set WIFI SSID and password
      #define MY_ESP8266_SSID redacted
      #define MY_ESP8266_PASSWORD redacted
      
      // MQTT broker ip address.
      #define MY_CONTROLLER_URL_ADDRESS redacted
      
      // The MQTT broker port to to open
      #define MY_PORT 1883
      
      #include <ESP8266WiFi.h>
      #include <MySensors.h>

      Bounce debouncer = Bounce();

      MyMessage msgCount(CHILD_ID,I_LOG_MESSAGE);

        // After setting up the button, setup debouncer
        debouncer.attach(BUTTON_PIN);
        debouncer.interval(5);
      
        countHeartbeat = 0;
      
        //Setup the Pulse LED
        pinMode(LEDRED, OUTPUT);
      
        //Setup the Status LED
        pinMode(LEDGREEN, OUTPUT);
        digitalWrite(LEDGREEN, HIGH);
      }
      
      void presentation() {
      
        sendSketchInfo(MCU_ID, "1.0");
        present(CHILD_ID, S_BINARY);
        //present(HEARTBEAT_ID, S_BINARY);

      void loop()

        // Get the update value
        int value = debouncer.read();
        countHeartbeat ++;
        if(countHeartbeat >= 1155000){
          //Serial.println("Heartbeat");
          send(msgHeartbeat.set(1));
          countHeartbeat = 0;
        }
        
        if (value != oldValue) {
           // Send in the new value
           send(msg.set(value==HIGH ? 0 : 1)); 
           oldValue = value;
           if ( value == 1) {
              //Serial.println("Off");
              digitalWrite(LEDRED, LOW);
              delay(30);
           } else {
              //Serial.println("On");
              digitalWrite(LEDRED, HIGH);
           }
           
        }
        //send(heartbeat.set(value==1));
      }
      

      I appreciate any hint or comment!

    • RE: Problem with NRF24L01+PA+LNA (Gateway - Sensor Connection)

      We bought these: NRF24L01+ PCB Adapter

      We do not use any capacitor.

      What irritates me, the gateway works (ethernet gateway) with the +PA+LNA, whereas the sensor nodes do not. We have switched the PCB Adapters and antennas without any change.

      @gohan I bought the voltage regulators for nrf24 and provide 5V, but still...

    • RE: How to get sensor data into influxdb?

      @Yveaux do you also use Grafana in order to visualize the data? I am not sure what fields/attributes are necessary despite "time" and "value" for a binary sensor.

      It's weird, as it seems to work for my Gateway, but as soon as my sensors are connected with the +PA+LNA, they cannot register. 😞

    • RE: Problem with NRF24L01+PA+LNA (Gateway - Sensor Connection)

      Thanks a lot guys. Can you recommend a suitable power supply? And what capacitator should I get?

      And how does the RFM69 compare to the NRF24L01?

      Thanks for your help, once again.

      I have only connected it to the Nano's 3.3V port yet.
      Unfortunately, I didn't know that disconnecting the antenna might damage the radio. But I did only try it with one of the radios.

      How should I then connect it properly if the 3.3V is insufficient?

      Thanks in advance.
