Control RGBW 2 with a button for just brightness (how??)

[petervanderpol 1]

Dear all,

 

I have been reading many posts all over the internet, but I didn't find a new/pure answer (Or I got it wrong).

 

I want to be able to use a single momentary switch to control the brightness (1-100) of the color it is in at that moment.

Color I want to be able to set using smartphone or HC2.

 

• I have an Fibaro HC2
• I have an RGBW 2 module
• Momentary/pulse switch is connected to IN1 and to ground.
• I have an RGBWarm-White Ledstrip connected to R-G-B-W.

 

That is all, how can I configure this without Parameter 14?

 

I am so confused.

 

Thank you! Really looking forward to your reply.

Okay, will be giving an answer to my own question;

 

 

What I want:

I want to switch my RGBW lighting with a button (preferably 3), where I want the RGBW lighting to remember the last color configuration it was in.

With this button, I would also like to have the ability to dim the lighting as I can do with the Fibaro Dimmer.

 

Problem description:

Per default (With a Homecenter 2 & Parameter 14 missing) this is not supported.

The Line in (1,2,3,4) correspondate only with the automatically mapped color (Red, Green, Blue, White).

If you attach a momentary switch to on of the lines, only thát color will light-up. 

The other problem is that the RGBW is an 12/24 volts system, if you live in (for instance the Netherlands) you don't want to have a 220volt and 24volts setup in the same system.(Later in time you might be confused and blow-up things).

 

 

How to solve:

The only way how to solve this with an HC2 is to use an extra Fibaro Dimmer (2) module (warning: This setup is only tested with a dimmer 2 module & RGBW 2 module)

This way, when clicking the switch attached to your dimmer will also activate your RGBW module.

The only issue I have noticed is that the signal from the dimmer module to the RGBW module is only send when you have released your button while dimming.
This makes it a bit tricky to get the correct brightness as you are used with the dimmer modules.

 

Step 1: Install your fibaro dimmer 2 how you would normally also install this, this can be standard or with multi-way switches. I have used this:

Step 2:  Install your fibaro RGBW 2 with the 12v/24v system with your leds, do not attach a switch, this is useless.

Step 3:  Configure your modules in Fibaro, make sure that you name the modules as  you can idenfity them, you will need these names in the next steps

Step 4:  Go into HC2 and open your dimmer device, go to Advanced and select "Setting Association"

Step 5:  Open ENDPOINT 0 , select Group 2 and now select your RGBW device

Step 6:  Press 'Save'

Step 7:  Check if it works.

 

 

This is how it works for me, I've made an sample setup where I have started with a normal 2-switch dimmer 2 setup. (dimmer 2 is underneath the bottem switch build-in).

On the top right corner, I've added the LED (24v) system with the RGBW 2 module. This is associated with the Dimmer 2 module.
I've kept the light attached, which is in this example a bit weird because you would probably only control the leds with it. But it does give a little bit more clarity towards the dimming.

 

 

Hope this helps!

Peter
