Mysensors RGB node not added with "Not a valid message" error

Configuration
1

I’m runnin home-assistant 0.89.2 (also tried upgrading to 0.90 beta 4) on hassbian. Also running mysensors gateway 2.3.1 on the same rpi. Also I have test mysensors node (v. 2.3.1) presented as “S_RGB_LIGHT”. Problem is that home-assistant gives me an error and doesn’t add this node to the list.

“26” - is a type value for “S_RGB_LIGHT” in mysensors Serial API. Somehow home-assistant doesn’t recognize it. The same node is working with domoticz on the other rpi.

What’s your mysensors config bit of your configuration.yaml?

3 
mysensors:
  gateways:
     - device: '127.0.0.1'
        tcp_port: 5003
        persistence_file: '/home/homeassistant/.homeassistant/mysensors.json'
    persistence: false

Here’s your fix:

mysensors:
  gateways:
     - device: '127.0.0.1'
        tcp_port: 5003
        persistence_file: '/home/homeassistant/.homeassistant/mysensors.json'
    persistence: false
    version: 2.0

The default is 1.4 which didn’t have S_RGB_LIGHT

Yes, about that. I forgot to mention, that I tried adding versions “2.3.1”, “2.3”, “2.0”. It gives another error:

After trying to make it this way I’ve deleted “version” string from config and was getting those other errors.

Can you post your sketch?

// Enable debug prints
#define MY_DEBUG

// Enable and select radio type attached

#define MY_RADIO_RF24
#define MY_RF24_CHANNEL 88
#define MY_NODE_ID 80

#include <MySensors.h>
#include <Adafruit_NeoPixel.h>

#define RGBPIN PD3
#define NUMPIXELS 12

#define SN "RGB Dimmable Light"
#define SV "1.0"

MyMessage rgbMsg(1, V_RGB);

Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, RGBPIN, NEO_GRB + NEO_KHZ800);

void setup()
{
  pixels.begin();
}

void presentation()
{
  // Send the Sketch Version Information to the Gateway
  sendSketchInfo(SN, SV);

  present(1, S_RGB_LIGHT, "RGB_test");

}

void loop()
{
}

void receive(const MyMessage &message)
{
  if (message.type == V_RGB) {
    Serial.println( "V_RGB command: " );
    Serial.println(message.data);
    long number = (long) strtol( message.data, NULL, 16);

    // Split it up into r, g, b values
    byte red = number >> 16;
    byte green = number >> 8 & 0xFF;
    byte blue = number & 0xFF;
    setRGB(red, green, blue);
  }
}

void setRGB(int r, int g, int b)
{
  for (int i = 0; i < NUMPIXELS; i++) {

    pixels.setPixelColor(i, pixels.Color(r, g, b)); // Moderately bright green color.

    pixels.show(); // This sends the updated pixel color to the hardware.

    delay(300); // Delay for a period of time (in milliseconds).

  }
}

As I’ve mentioned this same sketch works as it should with domoticz.

Everything looks ok, I’d suggest sending the RGB color back to home assistant with the send function.

What’s in your /home/homeassistant/.homeassistant/mysensors.json ?

Nothing. I disabled persistence and deleted json file while trying to deal with this. That didn’t help though :slight_smile:
Ok, I will now try your suggestion about sending value first.

10

YAY! That worked. So as I understand you need to send something from node to home-assistant to register it. Even if it primarily receiving node. Bad that it isn’t said anywhere explicitly.
Thanks for the help, man :slight_smile:

Actually it says in the presentation section on:

Send at least one initial value per V_TYPE. In version 2.0 of MySensors, this has to be done in the
loop function. See below for an example in 2.0 of how to make sure the initial value has been received
by the controller.

No worries tho I made the same mistake with my RGB Light strip.

You’re right, my bad. It slipped from my attention. I thought in was related to mysensors part, I am just used to other logic of doing this type of things :slight_smile:

13

That’s why the forums exist :smiley:
