Saving Hue color lights to variable [solved]

Hi,

I'm trying to write a script that when an kodi start playing a video two hue lights wil switch to an specific scene. This isn't the tricky part.
However i would like that when kodi is paused or stopped the hue lights switch back to the previous color and brightnes (1 light only does brightnes so that simple)

Is there a trick to save the last color before switching the scene?

Ok that took longer than expected to have a go with it.

Anyway i figured that the Hue go i use doesn't really like to respond to it,

Tried some basics with setting to Go to a color read the RGB values an then do a color(rgb) but i end up with completle different colors and values.

So my gues i have to do something with other value's but now shure how to do that?

I can get some Json strings what i get from the GO when i'm back home.

Can you try this approach ?

Code: Select all

-- KeepRestoreRGB

return {
    on =        {   devices                 = { "safeColor","getColor"}}  ,

    data    =   {   previousColor           = { initial = {} },
                    previousBrightness      = { initial = -1  }},
    
    logging =   {   level                   = domoticz.LOG_DEBUG,
                    marker                  = "KeepRestoreRGB" },
                        
    execute = function(dz, item)
        local rgbLight = dz.devices(156)
        
        local function internalURL(url)
            dz.openURL({
                            url = dz.settings['Domoticz url'] .. url,
                            method = "GET",
                        })
        end
        
        local function setColor(idx,color,brightness) 
            myUrl =  "/json.htm?type=command&param=setcolbrightnessvalue&" .. 
                    "idx=" .. idx .. 
                    "&color=" .. color ..
                    "&brightness=" .. brightness
            internalURL(myUrl)
        end

        if item.name == 'safeColor' or dz.data.previousBrightness == -1 then
            dz.data.previousColor       = dz.utils.fromJSON(rgbLight.color) -- Safe current color in dzVents persistent data
            dz.data.previousBrightness  = rgbLight.level                    -- Safe current brightness in dzVents persistent data
        elseif item.name == "getColor" then
            setColor(rgbLight.idx, dz.utils.toJSON(dz.data.previousColor), dz.data.previousBrightness)
        end
    end
}

I think i'll allmost get the jist of that. I'll try to implement this tomorow and let you know if it works. :)

Ok I tested this and i'm working on some logging but what i can see:

Setting the light by hand works

Code: Select all

setColor(light.idx,dz.utils.toJSON({["g"] = 198;["t"] = 0;["cw"] = 0;["b"] = 254;["r"] = 221;["m"] = 3;["ww"] = 0;}),57)
Setting the DATA to storage works too, however changing the value back doesn't work

Code: Select all

dz.data.previousColor       = dz.utils.fromJSON(light.color) -- Safe current color in dzVents persistent data

Code: Select all

setColor(light.idx, dz.utils.toJSON(dz.data.previousColor), dz.data.previousBrightness)
Looking at the logs it looks like to work:

Code: Select all

(prev is DZ Data before saving to the new value, Current is the actual light.color)

The problem i run into is that when setting the color directly it goes ok. It gets the color i expect. But when switch back it only reacts to the brightness it looks like.

Sorry too hear that but I am kind of out of options with this now. Maybe @narel or @dannybloe can help you further. @narel created a setColBrightness method according to a post in this topic (I have not seen that one yet)

Looked at it again and added a function colorTable2String. This seems to make a difference compared to the previous toJSON function.
also included the optional iswhite parm for the json call (defaults to false).
Tested the modified script on my Hue bulbs and they return to the safed state as designed. As before; very much interested in your findings.

Code: Select all

-- KeepRestoreRGB

return {
    on =        {   devices                 = { "safeColor","getColor"}}  ,          -- dummy triggerDevices to test the script 

    data    =   {   previousColor           = { initial = {} },
                    previousBrightness      = { initial = -1  }},
    
    logging =   {   level                   = domoticz.LOG_DEBUG,
                    marker                  = "KeepRestoreRGB" },
                        
    execute = function(dz, item)
        local rgbLight = dz.devices(156)           -- IDX of your colour bulb
        
        local function internalURL(url)
            dz.openURL({
                            url = dz.settings['Domoticz url'] .. url,
                            method = "GET",
                        })
        end
       
        local function colorTable2String(colorTable)
            local colorString    = "{"              -- transform table contents into formatted string 
            for k,v in pairs(colorTable) do 
                colorString = colorString .. '"' .. k .. '":' .. v .. "," 
            end
            return colorString:sub(1, -2) .. "}"
        end
       
        local function setColor(idx,color,brightness,iswhite) 
            myUrl =  "/json.htm?type=command&param=setcolbrightnessvalue&" .. 
                    "idx=" .. idx .. 
                    "&color=" .. color ..
                    "&brightness=" .. (brightness or 100) ..
                    "&iswhite=" .. (iswhite or "false")
            internalURL(myUrl)
        end

        if item.name == 'safeColor' or dz.data.previousBrightness == -1 then
            dz.data.previousColor       = dz.utils.fromJSON(rgbLight.color) -- Safe current color in dzVents persistent data
            dz.data.previousBrightness  = rgbLight.level                    -- Safe current brightness in dzVents persistent data
        elseif item.name == "getColor" then
            setColor(rgbLight.idx, colorTable2String(dz.data.previousColor), dz.data.previousBrightness)
        end
    end
}

Hm this seems to work better. Still not completly satisified with the colors but working on it.

Thanks!
