Philips Hue: how to get state of lamp?

[thijs 1]

I am looking for a way to read the On/Off value of my Philips Hue light to control if they are actually on.

I have managed to get my Philips Hue set working with the help of the following thread:

For other modules, like sensors from Homewizard, I have managed to read sensor values with decoding the json files (json.decode) and assign them to customized variables through the Variable Panel. However for my Philips Hue set this won't work as the On/Off state is a boolean (text) value and I am not able to retrieve that value through the json.decode command.

Please help me to find a way to read out these values and assign them to a variable in order for me to get feedback on whether or not all of my Hues are one.

Hope someone can provide some very usefull tips.

I also tried to get the state of my Hue lights, but did not manage to get it working. My problem was that the 'GET' command did not give a response to HC2 in most cases. It seems that there are similar problems with Arduino, see the Everyhue forum:

I only control my Hue lights with my HC2 by means of motion sensors and wall switches with Fibaro dimmers with scene activation enabled (not with the Hue app). As a workaround I use a global variable to store the state of my Hue lights:

I've managed to solve this issue. Please see lua script below the 2 options that I use to control if my Hue lights are on. Debugging a boolean value in lua can be done with "fibaro:debug(tostring(state))"

Basic LUA script:

HueGtw = Net.FHttp("",80)

-- geting info from your Personal Weather Station

response = HueGtw:GET("/api/automation1/lights/2")

-- decoding json file

jsonTable = json.decode(response)

Option 1):

-- debugging specific data

local state = jsonTable.state.on

--debugging boolean value of ‘state’

fibaro:debug(tostring(state))

--set Global variable

fibaro:setGlobal("Hue2_state_on", tostring(state))

--set label value for virtual device #153

fibaro:call(153,"setProperty","ui.Label1.value",tostring(state))

Option 2):

--create local variable

local state = jsonTable.state.on

--then setup compare function with followup command

if state == true

then fibaro:debug("on")

fibaro:log("WK on")

fibaro:setGlobal("Hue2_state", "On")

fibaro:call(153,"setProperty","ui.Label1.value","On")

else fibaro:debug("off")

fibaro:log("WK off")

fibaro:setGlobal("Hue2_state", "Off")

fibaro:call(153,"setProperty","ui.Label1.value","Off")

end
