ESP8266gateway with sensor



  • Hi,

    I would like to use the ESP8266gateway standalone with a sensor. I used the ESP8266gateway sketch and it connects without problems to my controller, but I can't get it to send a message to the controller (FHEM).

    I made a very easy code, for testing. It would just be "light level" but in this case even without a sensor, just sending "100".

    /*
      */
    
    // 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
    
    // Enables and select radio type (if attached)
    //#define MY_RADIO_RF24
    //#define MY_RADIO_RFM69
    //#define MY_RADIO_RFM95
    
    #define MY_GATEWAY_ESP8266
    
    #define MY_WIFI_SSID "this is the SSID"
    #define MY_WIFI_PASSWORD "And the password"
    
    // Enable UDP communication
    //#define MY_USE_UDP  // If using UDP you need to set MY_CONTROLLER_IP_ADDRESS or MY_CONTROLLER_URL_ADDRESS below
    
    // Set the hostname for the WiFi Client. This is the hostname
    // it will pass to the DHCP server if not static.
    #define MY_HOSTNAME "ESP8266_Greenhouse"
    
    // Enable MY_IP_ADDRESS here if you want a static ip address (no DHCP)
    //#define MY_IP_ADDRESS 192,168,178,87
    
    // If using static ip you can define Gateway and Subnet address as well
    //#define MY_IP_GATEWAY_ADDRESS 192,168,178,1
    //#define MY_IP_SUBNET_ADDRESS 255,255,255,0
    
    // The port to keep open on node server mode
    #define MY_PORT 5003
    
    // How many clients should be able to connect to this gateway (default 1)
    //#define MY_GATEWAY_MAX_CLIENTS 2
    
    // Controller ip address. Enables client mode (default is "server" mode).
    // Also enable this if MY_USE_UDP is used and you want sensor data sent somewhere.
    //#define MY_CONTROLLER_IP_ADDRESS 10, 0, 78, 204
    //#define MY_CONTROLLER_URL_ADDRESS "my.controller.org"
    
    // Set blinking period
    //#define MY_DEFAULT_LED_BLINK_PERIOD 300
    
    // Flash leds on rx/tx/err
    // Led pins used if blinking feature is enabled above
    //#define MY_DEFAULT_ERR_LED_PIN 16  // Error led pin
    //#define MY_DEFAULT_RX_LED_PIN  16  // Receive led pin
    //#define MY_DEFAULT_TX_LED_PIN  16  // the PCB, on board LED
    
    #include <MySensors.h>
    #define CHILD_ID_LIGHT 0
    
    MyMessage msgLight(CHILD_ID_LIGHT, V_LIGHT_LEVEL);
    
    uint32_t WAIT_TIME = 1200; // Sleep time between reads (in milliseconds)
    
    
    
    void setup()
    {
    	
    }
    
    void presentation()
    {
      sendSketchInfo("GreenhouseWifiNode", "1.0");
      present(CHILD_ID_LIGHT, S_LIGHT_LEVEL);
    }
    
    void loop()
    {
    	//Light
      int16_t lightLevel = 100;
      Serial.println(lightLevel);
      send(msgLight.set(lightLevel));
    
      wait(WAIT_TIME);
    }
    

    This is the serial output:

    pm open,type:2 0

    100
    ...
    

    Any ideas what I do wrong?

  • Here is my code for doing something equivalent. You seem to have the pinMode line missing in setup()

    // Initialize motion message
    MyMessage msg(CHILD_ID, V_TRIPPED);
    
    void setup() { 
      pinMode(MOTION_SENSOR_PIN, INPUT_PULLUP);      // sets the motion sensor digital pin as input
    }
    
    void presentation() {
      // Present locally attached sensors here    
      // Send the sketch version information to the gateway and Controller
      sendSketchInfo("Motion Sensor", "1.1");
    
      // Register all sensors to gw (they will be created as child devices)
      present(CHILD_ID, S_MOTION);
    }
    
    boolean pinstate = false;
    
    void loop() {
      boolean newstate = (digitalRead(MOTION_SENSOR_PIN) == HIGH);
      if (newstate != pinstate) {
        if (newstate == true) {
          send(msg.set("1"));
          Serial.println("Motion Started");
          pinstate = newstate;
        } else {
          send(msg.set("0"));
          Serial.println("Motion Stopped");
          pinstate = newstate;
        }
      }
    }
