call for help: rgbW

[martinschki]

Hi there!!
First of all, thank you for this amazing program. I had it running together with my MQTT server literally in minutes...

Heres my plan. I'm making a "cloud lamp" for my sons room with SK6812 which will do three things.

1. simulate the weather forecast for the next day: I will use node-red for that and depending on the forecast light the lamp
2. use the "W" in RGBW as a normal room lamp
3. use the "W" as a wake up light in the morning by dimming the "W" to max over a period of time. Also for this I will use node red via MQTT and dim the lamp

As far as I understand Tobias, it is difficult to implement the fourth color into the code. So here's my question, because, everything except the "W" works:

Is there a simple way, or a "hack" how I can send brightness to the 4th LED??
I'm using the "NEO_GRBW" setting already which works perfect in RGB.

Any help on how to insert a new MQTT command which turns on all the "W"s with the sent brightness would be appreciated...
Thank you!
Martin

btw. I got the inspiration for the project here:

There are already a lot of variants floating around but none would be as elegant as this one..... :)

Please see #94

[martinschki]

i did....
but not being the uber programmer, I'd need someone to point me in the right direction...please...

@martinschki The McLighting version thats mentioned in #94 supports RGBW. You could just take this version to use your RGBW strip: https://github.com/FabLab-Luenen/McLighting

[martinschki]

i tried that but there are things not like in the latest master (MQTT is different, the blue led is always on?)
Is there a way to sync #94 to the latest master??

[toblum]

The RGBW version has many changes in the code that would make problems for other users. That's the reason why I didn't integrate it so far. It would take a lot of rework and could break existing integrations.

[bpohvoodoo]

All changes until today from this repository have been applied.

[debsahu]

@bpohvoodoo NeoAnimationFX does not support RGBW as of now, so you could remove the NeoAnimationFX code. Since neither I or @toblum have this kind of light strips, support may be far away. Replacing RgbColor to RgbwColor should be able to convert most of the animations to RGBW format, maybe I will create a separate branch (no promises).

[toblum]

I have one of those SKsomething strips from china lying here around, but I never got it to work (only as RGB). Maybe this was a fake product. Maybe I will buy another one in the future and give it another try.

[bpohvoodoo]

Maybe i will have a look at your Lib and convert it, too.

[martinschki]

I will test with my strip (SK6812 RGBWW) later today. Thanks!!!!

@bpohvoodoo work in progress?
does need a couple of extra pics and now I'm stuck...
(I don't have a color sensor(?)

replace

with
#ifdef ENABLE_BUTTON_GY33
tcs.setConfig(MCU_LED_05, MCU_WHITE_ON);
#endif

comment out
#define ENABLE_BUTTON_GY33
in definitions.h
//#define ENABLE_BUTTON_GY33

or redownload repo. It is fixed now.
Please upload the \clients\web\build\index.html of my repo.

[martinschki]

did!
it's now building and working!
(the repo https://github.com/FabLab-Luenen/McLighting doesn't have the changes in...)

two follow ups:

• how do I turn off the blue LED on the board (it's not on in Tobias' version)
• how do I control the white LED via MQTT?

Thanks!

Ups, forgotten to sync repos! My fault.

Are you sure? I haven't changed anything regarding the BUILTIN_LED.

how do I control the white LED via MQTT?

Haven't set up a mqtt server yet, but you should send color as
FF000000 for white
00FF0000 for red
0000FF00 for green
and
000000FF for blue

[martinschki]

thanks, white is working via MQTT as you said!

as for the blue LED: its on in your fork and off in the orig...
(i have a LoLin NodeMCU V3)

[debsahu]

@martinschki Comment out all lines that have BUILTIN_LED to turn off LED, add // before the line. Preliminary looking at the code the RGBW fork does nothing special to BUILTIN_LED. The behavior should be the same as the master branch here. Lolinv3 has no onboard led as lolin v2 where gpio16 has a red led. But both have a blue led connected to gpio2 which is in the ESP8266-12E top right corner.

[JoJ123]

I adapted the McLightning adapter to support the RGBW Fork
https://github.com/JoJ123/ioBroker.mclighting/tree/feature/rgbwSupport

[ChristophA]

Are there any plans to add RGBW features to the original McLighting fork?

[JoJ123]

I think they said, there are too many changes and differences between the codes
