Unable to publish to losant

Sindhuja_Yadavilli · March 17, 2018, 7:04am

Hello,
I’m working on Mongoose os with dallas temperature sensor DS18B20 and esp8266 nodemcu. I’m using js code and i’m able to get the sensor values to the device log of Mongoose. When i’m trying to publish the values to losant using Losant MQTT broker, I’m not able to do the same. Though I’ve given my device id as Losant device id and saved the configuration, it still says Published no topic to /esp8266_49C75D, this device id.

The device log is like this:

If observed, when i re-save the configuration initially the device id changes to losant device id but again it changes back to /esp8266_49C75D.
Can you please help me with this isssue?

Dylan_Schuster · March 19, 2018, 1:17pm

It looks like your device starts by correctly making state reports to /losant/5aa9876c5f623600074b3fbd/state, which is correct.

Then, on reconnect, your device ID is changing to esp8266_49C75D, which makes your state reports go to /losant/esp8266_49C75D/state instead, which as you know does not work.

Can you post a sample of the code you have running on the device? There’s not much we can do to diagnose the issue without that. Make sure not to include any sensitive information such as your access key and secret within the code sample.

This is the javascript code that I’m using in Mongoose:

/*
 * Copyright (c) 2014-2017 Cesanta Software Limited
 * All rights reserved
 *
 * This example demonstrates how to use mJS Arduino DallasTemperature
 * library API to get data from DSxx temperature sensors.
 */

// Load Mongoose OS API
load('api_config.js');
load('api_timer.js');
load('api_arduino_onewire.js');
load('api_arduino_dallas_temp.js');
load('api_mqtt.js');

// GPIO pin which has sensors data wire connected
//let pin = 21;
let pin = 13;
// Initialize 1-Wire bus
let ow = OneWire.create(pin);
// Initialize DallasTemperature library
let dt = DallasTemperature.create(ow);
// Start up the library
dt.begin();
// Number of sensors found on the 1-Wire bus
let n = 0;
// Sensors addresses
let sens = [];

// This function reads data from the DS sensors every 2 seconds
Timer.set(2000 /* milliseconds */, true /* repeat */, function() {
  if (n === 0) {
    n = dt.getDeviceCount();
    print('Sensors found:', n);

    for (let i = 0; i < n; i++) {
      sens[i] = '01234567';
      if (dt.getAddress(sens[i], i) === 1) {
        print('Sensor#', i, 'address:', dt.toHexStr(sens[i]));
      }
    }
  }

  dt.requestTemperatures();
  for (let i = 0; i < n; i++) {
    print('Sensor#', i, 'Temperature:', dt.getTempC(sens[i]), '*C');
    let temp = dt.getTempC(sens[i]);
    let topic = '/losant/' + Cfg.get('device.id') + '/state';
    let message = JSON.stringify({
      data: {
        temperature: temp
      }
    });
    let ok = MQTT.pub(topic, message, 1);
    print('Published:', ok? 'yes' : 'no', 'topic:', topic, 'message:', message);
  }
}, null);

If you change this line so that you reference the device ID directly instead of reaching into the config …

let topic = '/losant/5aa9876c5f623600074b3fbd/state';

Does it work as expected?
