Storing Hue Light status in a global variable


Recommended Posts



I'm struggling to create a scene or module to store hue light information in a global variable.

The purpose of it is that i want to signal some status changes through lights alerts (alarm activation/disactivation, move detection...).

The issue is that when the signalisation of the event is finished, i want to come back to my initial lights settings.


I don't want to get the information from fibaro HC2 but directly from the Hue Bridge, HC2 not being always updated with latest configuration.

My first ideas were:

  • to get devices list from HC2 and filter hue lights
  • get hue lightId from this
  • access the hue bridge and GET, lightId per lightId all configuration information
  • store this in a global variable.


I"m only starting in coding, LUA and so on and don't manage to get out of all the successive challenges it represent for me :)


At the moment, i'm trying to do a VD that looks appropriate for APIs usage with hue bridge and some other benefit.



    -- Getting all device information from HC2 


    local Device = api.get("/devices")

        for     i = 1, #Device do
                if         Device.parentId and Device.type == "com.fibaro.philipsHueLight"


                local fibaroId     = Device.id
                local lightId    = fibaro:getValue(fibaroId, "lightId")
                local on         = fibaro:getValue(fibaroId, "on")    
                local bri        = fibaro:getValue(fibaroId, "bri")
                local sat        = fibaro:getValue(fibaroId, "sat")
                local hue        = fibaro:getValue(fibaroId, "hue")
                local power        = fibaro:getValue(fibaroId, "power")
                local reachable    = fibaro:getValue(fibaroId, "reachable")
                local name        = fibaro:getName(fibaroId)
                local room        = fibaro:getRoomID(fibaroId)
                fibaroLightState ={}
                table.insert (fibaroLightState,1,name)
                table.insert (fibaroLightState,2,fibaroId)
                table.insert (fibaroLightState,3,lightId)
                table.insert (fibaroLightState,4,power)
                table.insert (fibaroLightState,5,on)
                table.insert (fibaroLightState,6,bri)
                table.insert (fibaroLightState,7,sat)
                table.insert (fibaroLightState,8,hue)
                table.insert (fibaroLightState,9,reachable)
                fibaro:setGlobal("fibaroLightState", json.encode(fibaroLightState))


I don't manage to check if it's well working and have the feeling that one iteration delete the previous one.

Can someone provide some help ? 

I would like to get an output that then enable me to request the hue bridge for each lightID :)


PS: Not doing manually as circ 50 hue lights :)


 Thanks in advance for your help :)

  • Hello all, 


    looks like i've partly found my solution to store in a global variale my hue lights configuration from the bridge (HUE BACKUP Button in a VD below).

    The idea, after an visual alert/alarm (not just blincking .... red, orange, blue... depending on event), being in a position to come back to initial settings with HUE RESTORE (VD below)

    However i'm missing something as it looks that ... it does,'t work... and i don't understand why...


    Can an expert have a quick look on this surely basic issue?

    Thanks in advance for any support or idea....
