MySensors S_RGB_LIGHT WS2812 ledstrip

[Ritmeester]

I’m sorry, but if I don’t understand or see it, than I get questions. Maybe it is simple, if you know HOW to make it, …. Yes than it is very simple.

I was really happy that I made a sketch with “wires” and that this is working with two (or more) mode’s. I have a little bit of programing experience.

I will see if I can figure out what is: 4 V_LIGHT

[tlpeter]

He means that you need to program 4 different "lights"
Read this page and see why it uses these names:

https://www.mysensors.org/download/serial_api_20

It defines which type to use like light is for light and V_TEMP orcourse for temperature.
Domoticz than knows which type of sensor is used.

[Ritmeester]

Thanks for your answers. But I still do not understand what kind of switch I have to make in my sketch.

This switch I have made:

2016-08-17_14-01-09.png (22.2 KiB) Viewed 6873 times

The mode buttons must change the pattern in the sketch.

How my “signals” from this Selector Switch will arrive in my node and the node is switching to a different pattern. (Mode)

[Ritmeester]

Ok , I will go to a wired connection for my question to use the Selector Switch for my situation. Unfortunately it seems not be possible to send a self-chosen command (variable) to an Mysensors node to handle this. With Wires it works very well.

Can I “combine” two or more switches in a JSON command?

Example:
I have two switches with IDX 50 and 51. In one command I want to switch them off like this:

Code: Select all

/json.htm?type=command&param=switchlight&idx=50&switchcmd=Off 

But then for two switches, or more in the same rule. Or can I make some group of switches to turn them off by one command?

I’m trying to get the sketch from gizmocuz to work with MySensors 2.0. I have made the necessary conversion from MySensors 1.5 to 2.0. It compiles without errors.

If I run the sketch the “SendColor2AllLEDs” works. And then it stops because I don’t get any information from Domoticz to this Node. So, Domoticz is not sending commands, or it is not receiving commands.
Maybe (pretty possible) that I have overlooked something but I don’t know what.

I am using AWI and Gimoz example on 1.5.1 and it is working fine.
I only changed type to Dimmer and then clicked on the three cubes to see color wheel, as soon as I selected a color it changed on my LEDs.
I don't know how 2.x is working but don't you need gw.process( or equal) in LOOP?

[NiklasO]

I don't know how 2.x is working but don't you need gw.process( or equal) in LOOP?

Nope. It will process automatically.

I am in the process to put up my ws2812b. Is there a sketch out there that works with 2.x or do I need to convert the older script?
Thanks!

[NiklasO]

Sketch for 2.x, working here. Add the new device, change to dimmer.

Anything I should take in considiration to modify this great example to RGBWW strip ??
So I see normal values travelling to Mysensors like 000000 for RGB and 000000FF for white.

I am currently working from:

Code: Select all

// Modified strandtest sketch to support also RGBW strips like SK6812 based:
// http://www.szledcolor.com/download/SK6812RGBW.pdf
// Should be used with Adafruit NeoPixel version 1.0.3
// Hacked by G. Knauf 2015-12-06

RGB is working however, still have some problems with the White Part. (it simply switches all leds off)

[sincze]

I'll answer my own question

If the received color starts with '#'. It is white. Just modify that in the mysensor code and it works fine.

Code: Select all

 if (received_message.startsWith("#")) 
    {
      color =  WHITE_LED;
    }
    else
    {
      color = strtol(message.getString(), NULL, 16);
    }

This has been working for a long time now, but today I noticed one small thing, it is not problem.

If the LED is ON and I restart my node, the LED will turn on after restart but in DZ it shows that the LED is OFF.
I think it be OFF when the node is presenting the Child.

Hello,
since the update of domoticz in version 4.10157 I have a problem
I set the lighting of the leds every night at 18:30 and level at 25% in domoticz the order is well given but the brightness remains at 0 I am forced by imperihome to increase it.
do you have this problem?
thank you
