Setting dimming value with Global Variable

[sebaszz 2]

Pfff can somebody help me..... somehow i'm stuck in my very limited lua knowledge, running version 4.049

 

Converting the brightness level from the hue 0-255 to the variable "Lights" to 0-100 is working

 

What doesn't work is the using the variable to update the dim level of ID 223

 

Hope somebody can help me out?

Please try this. Convert your calculated dimming level to the lowest integer, like this:

Could you explain why this works?

[petergebruers 1,268]

Certainly. The call to do a "setValue" expects an integer. Lua is dynamically typed, which means in this case that it deduces from the division by 2.55 that the resulting variable has to be a float. This makes the call fail silently. Using math.floor solves this and also makes printing or displaying the number a lot prettier. Have fun!

Ok thanx!

 

My next issue...

 

I'm reading out the status of the Hue plugin and want use that as a on/off trigger for the fibaro dimmer. 

 

When I read out fibaro:getValue(370, "on"). I see in a VD label it changing from 0 to 1 when switching on.

So tried to write to local variable and used it as a trigger if (Lightstatus == 1)

 

Doesn't work, copied to a globalvariable and now it's showing "nil"

I'm not sure I follow but "So tried to write to local variable and used it as a trigger" sounds suspicious. Only Global Variable (in the Variables Panel) can trigger scenes.

If you export and upload your virtual device (vfib) here, I can have a look at your code.

Managed to get it working by trying building something in a block scene and converting to lua,..

 

This the code now... that synchronize the dimmer with philips hue bulb

Many thanx for the help!

Glad I could help! Maybe two last things: you don't need "fibaro:call(223, "turnOn");" because the next line turns on the dimmer, if the level is between 1 and 99 (full on). And level 0 turns it off. Also the line beginning with "local trigger" isn't needed. You'll find some scripts that test or a certain value, but then you'll see an "if" statement referring to it. Have fun!

Hi

Tried to use your LUA code to controll three HUE light with a dimmer, but get an error code in debug:

[DEBUG] 22:14:10: line 16: attempt to perform arithmetic on local 'Dimminglevel' (a nil value)

 

The code I tried is:

 

--[[
%% autostart
%% properties
25 ui.brightness.value
25 on
%% globals
--]]

local trigger = fibaro:getSourceTrigger()

if (fibaro:countScenes()>1) then
  fibaro:abort();
end

local Dimminglevel = fibaro:getValue(25, "ui.brightness.value")
fibaro:setGlobal("Lights", math.floor(Dimminglevel / 2.55))

local Dimminglevel2 = fibaro:getGlobal("Lights")

local LightStatus = fibaro:getValue(25, "on")

if
 ( tonumber(fibaro:getValue(25, "on")) > 0 )
then
    fibaro:call(175, "turnOn");
      fibaro:call(175, "setValue", Dimminglevel2 )
    fibaro:call(176, "turnOn");
      fibaro:call(176, "setValue", Dimminglevel2 )
    fibaro:call(177, "turnOn");
      fibaro:call(177, "setValue", Dimminglevel2 )  
else
    fibaro:call(175, "turnOff")
      fibaro:call(176, "turnOff")
      fibaro:call(177, "turnOff")
end

 

I had regular lights in the room, but changed them to HUE E27 and wanted to control them with the dimmer/ add them to scenes ++.

 

Can you help me? Thanks
