Thank you!

After some reading and poorly written code i managed to get it working.

So i've been having this issue for a few days now when trying to add my new pwm-led dimmer to Home-assistant.

I cleared the eeprom and used the included mysensors example sketch and uploaded it to the arduino, started it and immediately got the error "child_id X already exists in children of node X, cannot add child"

so i enabled the debugging in home-assistant and i have the logs provided.

home-assistant log:

Can anyone point me in the right direction as to why this doesn't work it would be much appreciated.

Wow, this was a lot of information at once

I'm going to go through the code tomorrow and actually figure out whats going on. I'm contemplating actually writing my own code, instead of relying on someone else's. Might make things easier (or harder ) but in the end i think i might benefit from it.

i changed the code i had with the changes you suggested, and i can see the messages coming through to the gateway, but i still can't actually get home-assistant to display them. Trying to figure out if it's the code on the sensor, the code on the gateway or somewhere in-between that the message gets lost.

i really appreciate all your help, i'll get back as soon as i've revised my code and (knock on wood) got it to work

Again, thanks for all the help!

Hi,

I read the guide, the only thing i couldn't figure out was the "manual node id, or AUTO". Im not entirely sure how to define this. I used the mysensors-library standard dallastemperature-sketch

Sketch:

#include <SPI.h>
#include <DallasTemperature.h>
#include <OneWire.h>

#define COMPARE_TEMP 0 // 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 = 10000; // 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. 
MySensor gw;
float lastTemperature[MAX_ATTACHED_DS18B20];
int numSensors=0;
boolean receivedConfig = false;
boolean metric = true; 
// Initialize temperature message
MyMessage msg(0,V_TEMP);

void setup()  
{ 
  // Startup up the OneWire library
  sensors.begin();
  // requestTemperatures() will not block current thread
  sensors.setWaitForConversion(false);

  // Startup and initialize MySensors library. Set callback for incoming messages. 
  gw.begin();

  // Send the sketch version information to the gateway and Controller
  gw.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++) {   
     gw.present(i, S_TEMP);
  }
}


void loop()     
{     
  // Process incoming messages (like config from server)
  gw.process(); 

  // 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)
  gw.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>((gw.getConfig().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
      gw.send(msg.setSensor(i).set(temperature,1));
      // Save new temperatures for next compare
      lastTemperature[i]=temperature;
    }
  }
  gw.sleep(SLEEP_TIME);
}

What i managed to miss was a warning in the home-assistant.log 16-02-01 19:40:03 mysensors.mysensors: Error decoding message from gateway, probably received bad byte.

Not sure what that means exactly.
At startup it shows:Feb 02 19:34:48 raspberrypi hass[31732]: INFO:homeassistant.components.http:Starting web interface at http://0.0.0.0:8123 Feb 02 19:34:48 raspberrypi hass[31732]: INFO:mysensors.mysensors:Trying to connect to /dev/ttyUSB0 Feb 02 19:34:48 raspberrypi hass[31732]: INFO:homeassistant.core:Timer:starting Feb 02 19:34:48 raspberrypi hass[31732]: INFO:homeassistant.components.mysensors:update persistence: node 1 Feb 02 19:34:48 raspberrypi hass[31732]: INFO:netdisco.service:Scanning Feb 02 19:34:50 raspberrypi hass[31732]: INFO:homeassistant.components.media_player:Updating media_player entities Feb 02 19:34:50 raspberrypi hass[31732]: INFO:plexapi:GET http://10.0.1.11:32400/clients Feb 02 19:34:50 raspberrypi hass[31732]: INFO:requests.packages.urllib3.connectionpool:Starting new HTTP connection (1): 10.0.1.11 Feb 02 19:34:50 raspberrypi hass[31732]: INFO:plexapi:GET http://10.0.1.11:32400/status/sessions Feb 02 19:34:50 raspberrypi hass[31732]: INFO:requests.packages.urllib3.connectionpool:Starting new HTTP connection (1): 10.0.1.11 Feb 02 19:34:51 raspberrypi hass[31732]: INFO:mysensors.mysensors:/dev/ttyUSB0 is open...

So I'm having some issues with a newly built dallastemperature sensor. I'm using an arduino Nano, nrf24l01+ and 2 ds18b20. Used the latest library, with Arduino IDE 1.6.6 on Mac OSx.

Other side is a raspberry pi with a standard serial gateway (arduino nano, nrf24l01+ high power). Im running home-assistant on the raspberry. Home-assistant can see the serial gateway and it starts up as it should, the sensor-node however doesn't seem to report as it should.

The mysensor.json file that home-assistant creates just contain:
{"1": {"sketch_name": "Temperature Sensor", "type": 17, "children": {}, "sketch_version": "1.1", "battery_level": 0, "sensor_id": 1}}

And the log output of home-assistant/serial-gateway is:

Feb 02 18:23:41 raspberrypi hass[420]: INFO:mysensors.mysensors:n:0 c:0 t:3 s:9 p:read: 1-1-0 s=255,c=0,t=17,pt=0,l=5,sg=0:1.5.3

I'm hoping that someone can point me in the right direction on this. It is for whatever reason not showing up in home-assistant at all. And I'm unsure if i've made a mistake somewhere.

If this is posted in the wrong category I'm sorry.

Cheers

I had the same issue, tripplechecked my wiring and still had the issue. Added a decoupling capacitor between gcc and power and voilá it worked. So i would suggest starting with a capacitor, i use 10uf but others use 4.7uf with same effect.
