Problem with S_RGB_LIGHT

[danivalencia]

Hi all.

I'm trying to set up a test sensor, with a RGB Led attached to a Nano/NRF sensor.

For now what I have is this code borrowed from the domoticz forum, but the light doesn't show on the UI.

Any help apreciated (and sorry for my english :wink: )

#include <MySensor.h>
#include <SPI.h>

#define RED_PIN 3
#define GREEN_PIN 5
#define BLUE_PIN 6

#define NODE_ID 2
#define CHILD_ID 0
#define SKETCH_NAME "RGB_STRIP"
#define SKETCH_VERSION "1.0.0"
#define NODE_REPEAT false

MySensor gw;

long RGB_values[3] = {0, 0, 0};
float dimmer;

void setup() {


  pinMode(RED_PIN, OUTPUT);
  pinMode(GREEN_PIN, OUTPUT);
  pinMode(BLUE_PIN, OUTPUT);

  gw.begin(incomingMessage, NODE_ID, NODE_REPEAT);
  gw.sendSketchInfo(SKETCH_NAME, SKETCH_VERSION);
  gw.present(CHILD_ID, S_RGB_LIGHT, "RGB Strip", false);
  gw.request(CHILD_ID, V_RGB);
}

void loop() {
  gw.process();
}

void incomingMessage(const MyMessage &message) {

  if (message.type == V_RGB) {

    String hexstring = message.getString();
    long number = (long) strtol( &hexstring[0], NULL, 16);
    RGB_values[0] = number >> 16;
    RGB_values[1] = number >> 8 & 0xFF;
    RGB_values[2] = number & 0xFF;
  }
  if (message.type == V_DIMMER) {
    dimmer = message.getInt();
    analogWrite(RED_PIN, int(RGB_values[0] * (dimmer / 100)));
    analogWrite(GREEN_PIN, int(RGB_values[1] * (dimmer / 100)));
    analogWrite(BLUE_PIN, int(RGB_values[2] * (dimmer / 100)));
  }

  if (message.type == V_LIGHT) {
    if (message.getInt() == 0) {
      digitalWrite(RED_PIN, 0);
      digitalWrite(GREEN_PIN, 0);
      digitalWrite(BLUE_PIN, 0);

    }
    if (message.getInt() == 1) {
      analogWrite(RED_PIN, int(RGB_values[0] * (dimmer / 100)));
      analogWrite(GREEN_PIN, int(RGB_values[1] * (dimmer / 100)));
      analogWrite(BLUE_PIN, int(RGB_values[2] * (dimmer / 100)));
    }
  }
}

Hi!

You're not sending any initial values for each of the V_TYPES you want to use, in the end of setup. Have you read the instructions here?
https://home-assistant.io/components/mysensors/#presentation

Since you want to use V_RGB, V_DIMMER and V_LIGHT, you should populate all three data types. The device will show in the GUI, once you have at least populated the corresponding V_TYPE per S_TYPE that you present per sensor. In this case that's V_RGB corresponding to S_RGB_LIGHT.

@martinhjelmare

Thanks!

I think I figured out the solution, but not yet fixed at all.

I presented the three V_ types, and sent a value for each all. But now I'm dealing with the ON/OFF "order" for the light. It doesn't respond to the switch at the UI.

#include <MySensor.h>
#include <SPI.h>

#define RED_PIN 3
#define GREEN_PIN 5
#define BLUE_PIN 6

#define NODE_ID 2
#define CHILD_ID 0
#define SKETCH_NAME "RGB_LED"
#define SKETCH_VERSION "1.0"

MySensor gw;
MyMessage msgBright(CHILD_ID, V_PERCENTAGE);
MyMessage msgColor(CHILD_ID, V_RGB);
MyMessage msgLight(CHILD_ID, V_LIGHT);
long RGB_values[3] = {0, 0, 0};
float dimmer;

void setup() {


 pinMode(RED_PIN, OUTPUT);
 pinMode(GREEN_PIN, OUTPUT);
 pinMode(BLUE_PIN, OUTPUT);

 gw.begin(incomingMessage, NODE_ID, NODE_REPEAT);
 gw.sendSketchInfo(SKETCH_NAME, SKETCH_VERSION);

 gw.present(CHILD_ID, S_RGB_LIGHT);
 gw.present(CHILD_ID, S_DIMMER);
 gw.present(CHILD_ID, S_LIGHT);

 gw.request(CHILD_ID, V_RGB);
 gw.request(CHILD_ID, V_PERCENTAGE);
 gw.request(CHILD_ID, V_LIGHT);

 gw.send(msgBright.set(100));
 gw.send(msgColor.set("000000"));
 gw.send(msgLight.set(1));
}

void loop() {
 gw.process();
}

void incomingMessage(const MyMessage &message) {

 if (message.type == V_RGB) {

   String hexstring = message.getString();
   long number = (long) strtol( &hexstring[0], NULL, 16);
   RGB_values[0] = number >> 16;
   RGB_values[1] = number >> 8 & 0xFF;
   RGB_values[2] = number & 0xFF;
 }
 if (message.type == V_PERCENTAGE) {
   dimmer = message.getInt();
   analogWrite(RED_PIN, int(RGB_values[0] * (dimmer / 100)));
   analogWrite(GREEN_PIN, int(RGB_values[1] * (dimmer / 100)));
   analogWrite(BLUE_PIN, int(RGB_values[2] * (dimmer / 100)));
 }

 if (message.type == V_LIGHT) {
   if (message.getInt() == 0) {
     digitalWrite(RED_PIN, 0);
     digitalWrite(GREEN_PIN, 0);
     digitalWrite(BLUE_PIN, 0);

   }
   if (message.getInt() == 1) {
     analogWrite(RED_PIN, int(RGB_values[0] * (dimmer / 100)));
     analogWrite(GREEN_PIN, int(RGB_values[1] * (dimmer / 100)));
     analogWrite(BLUE_PIN, int(RGB_values[2] * (dimmer / 100)));
   }
 }
}

Any idea why?

@danivalencia

Yes, you are not sending back the updated state for the values after they have changed. By default home assistant will wait for feedback from the actuator for state update before updating the state in home assistant. This can be changed by setting the option optimistic to true in the config. But it's better to send back the updated state from the arduino.

Also, you don't have to present three sensors if you only have one actual rgb light. You can have all three V_TYPES, V_RGB, V_DIMMER and V_LIGHT for the one S_TYPE, S_RGB_LIGHT.

I'll update the docs on the web, cause I see now that the light page is not very clear about which types you actually can use.

@martinhjelmare

Thanks a lot!

So, I can remove two of the presentations, but I have to send three messages or can I send just one?

And for the respond to the gateway, can you show me an example?

Thanks again!

[martinhjelmare]

@danivalencia

I suggest still sending values for all three V_TYPES at the end of setup. But remove presentation of S_LIGHT and S_DIMMER, as you say.

The following is the sketch I've used when I tested the code. It's based on the LED dimmer example, and I've just added a dummy RGB light actuator which will just print out the received hex string, not actually changing any RGB LEDs. So just update the relevant parts of your sketch. I think it will work if you add the update of the states, by sending in those values.

I tried your sketch as is, just to try one leg for the RGB Led, but I'm not getting the expected result. When I change the brightness from the HA UI slider, the node gets the correct value, but...

As you see, no matter what level receives, It goes to 100 forever.
And if you try to move the brightness slider more over to the right (or the left to reduce), the values sometimes get higher than 100 (or -100), despite of the "clipping" method of the sketch.

EDIT:

Made a few changes to the code, to find what's failing, and I think is the way HA sends commands to the node;

...

  if (message.type == V_DIMMER) {

    //  Retrieve the power or dim level from the incoming request message
    int requestedLevel = atoi(message.data);
    Serial.print("Received: ");
    Serial.println(message.data);
    Serial.print("Bright: ");
    Serial.println(requestedLevel);
...

And the log from the sensor:

Seems there is a string of the message (sketch name maybe) messing with the brightness data.

@danivalencia

I think this was a bug in mysensors 1.5.2 - 1.5.3. Can you try version 1.5.4?

[danivalencia]

@martinhjelmare

And there was the fail !! :s

Installed 1.5.4 and now it runs in the right manner.

Thank you!!
