RGBW as remote controller for other dimmers

[Jamie mccrostie 82]

Say you want to use a RGBW module to control other dimmer2 devices in your set up.

The following scene and settings will let you do just that.

Useful also if you are trying to upgrade a old bus wired smart home systems with home run controlled circuits

 to zwave system.

Mount RGBW modules in old system switch locations. Use old bus wiring as 12v/24v RGBW supply.

Replace old din mounted dimmer and switch modules at control cabinet  with zwave devices giving you up to 4 switches

per RGBW module.  

 

 

Solved, thanks @ReneNL

and @Soporte Life2Better for response time hint

Use this scene, set module to output mode, set parameter 10 to 1 sec

488 = RGBW module id

122  to 118 =  controlled  remote dimmers id's 

 

 

--[[
%% properties
488 value
%% events
%% globals
--]]

rgb = 488
dimmer1 = 122
dimmer2 = 152
dimmer3 = 156
dimmer4 = 118

function split(source, delimiters)
    local elements = {}
    local pattern = '([^'..delimiters..']+)'
    string.gsub(source, pattern, function(value) elements[#elements + 1] = value; end);
    return elements
end 
colorstatus = split(fibaro:getValue(rgb, "color"),",")

fibaro:call(dimmer1,"setValue", math.floor (100*(colorstatus[1]/255)))
fibaro:call(dimmer2,"setValue", math.floor(100*(colorstatus[2]/255)))
fibaro:call(dimmer3,"setValue", math.floor(100*(colorstatus[3]/255)))
fibaro:call(dimmer4,"setValue", math.floor(100*(colorstatus[4]/225)))

Thinking about this....

Im actually after input to  channel 1 as a dimmer value when RGB is in input/ output mode with all channels set to input.

dimmedvalue = tonumber(fibaro:getValue(122,”value”)) — where do I insert the channel 1 bit?

                                              fibaro:call(125,”setValue”, dimmedvalue)

What Im trying to figure out is how to use a remote RGBW module connected to 4 push button switches and thru lua have them control 4 seperate dimmer2s.

?

Hi @Jamie mccrostie,

 

The LUA commands to set the individual color channels are:

With RGBWid your device ID, dimlevel a value between 0 and 255 (i.e. not 100). Instead of "setG" you have "setR", "setB" and "setW" for the other channels/colors.

 

To read the value is a bit more tricky (at least I did not find an easier way, maybe I missed something...):

 

Get the current status of all 4 channel:

And now you can access the value of each channel by using colorstatus[1] for red, colorstatus[2] for green, colorstatus[3] for blue and colorstatus[4] for white. As the RGBW color status is a number from 0-255 we need to convert to 0-100 for the dimmer (and round it to get integer values):

Hope this help.

 

Rene.

@ReneNL

Thanks for your efforts not quite what im after though.

Im trying to use the 4 imputs  on rgb module via attached push buttons to control

4 seperate dimmer 2s in the system

The rgb has no strip attached so Im just using it for remote dimmer control.

 

Maybe this has to be done in input mode?

[ReneNL 48]

Apologies if I'm still wrong, but I think the above should work for your purpose. It seems you need to get the dimvalue of the 4 RGBW channels and set the dimmer2 dimvalue accordingly, right?

 

So the code would be something like (have not tested):

Cool I’ll dive into it tomorrow morning.

Thanks again for the help

I’ll report back if I have  success.
