better hue integration?

[prein]

When I am changing my philips light bulbs using other software than domoticz (for instance via Hue app or via Hue Tap) I can see that the status of the light bulbs change in domoticz. That is good!
However, I can't use it in scripts. It seems that only the GUI of Domoticz is updated, but not the real (database) values.

for example:
hue was turned off using hue-tap. shows off in domoticz, but when I ask for the status in LUA script it still says: on. This means I am unable to make scripts based on the status of the hue lights.

so for an alternative solution I created a dummy switch with a lua time event that triggers when the hue light last seen info is updated. But altough the last seen information is updated on the screen, the information I get from LUA still is the old information.

The workaround for this is that I have a lua time event that polls the status of my light bulb directly from the hue bridge, updating a dummy sensor. But it has to run every minute, since there is no reliable information within Domoticz that can be used when scripting.

Is this a bug and will this be changed?

[bbqkees]

Can you post your script?

[prein]

Note that I have commented out the if statement that checks for the device update. Meaning it now runs every minute.
Code is very rough, full of dirty comments and unneccesary print commands... sorry for that


replace: $$APIUSERKEY$$ with your philips hue user ID

note that the hue bulb I am checking is named: Betty
The Dummy switch is named: Hue Status
In the Hue bridge, I am calling light number 2

Furthermore I had to implement some plugins, taken from the Wiki (create the directories if they don't exist):

Secondly, you need to install the socket and luacolor libraries on your machine, I have attached gzipped tar files for the Raspberry Pi to this forum post, as there is no packaged versions available. Download the two attached files, placing usrlocalsharelua5p2.tar.gz in directory /usr/local/share/lua/5.2/ and extracting the file with sudo tar -xvf usrlocalsharelua5p2.tar.gz, then put usrlocalliblua5p2.tar.gz in /usr/local/lib/lua/5.2/ and extract all the files with sudo tar -xvf usrlocalliblua5p2.tar.gz.

socket and luacolor from: http://www.domoticz.com/forum/viewtopic ... 638#p22638

[bbqkees]

I meant the code you used in the first place which did not work.

You have to keep in mind that 'on' is not really defined for dimmers, it is f.i. '"Set Level, Level: 43 %".
When off it is "Off, Level: 32 %".

There was something with dimmer als LUA, not sure what really works.

I tried:

otherdevices['Betty'] will allways give the same result (on/off/dimmed, nothing changes) : --> LUA: Set Level
otherdevices_svalues['Betty'] will also always give the same result: --> LUA: 210;13199 (these values also never change, not when on, off, only with different colour)

[bbqkees]

I will try to reproduce the problem.
What version of Domoticz are you using?

[prein]

thanks! using latest stable version: v2.3530

[Derik]

I do have/use this script...
When i use a button of my remote i activate this script.[ with a dummy button, and place the adres to my script ]
Always the good color etc..
After a other device i click a button on my remote, works simple..

Code: Select all

#!/bin/sh
curl -H "Accept: application/json" -X PUT --data '{"on": true,"bri": 500,"hue": 13088,"sat": 212,"xy": [0.5128,0.4147],"ct": 467,"alert": "none","effect": "none","colormode": "xy","reachable": true}' http://192.168.5.36/api/newdeveloper/lights/4/state

I get this code with the developer api from Hue.

[prein]

I have got this kind of integration as well. The problem is that when I switch lights using non-Domoticz Apps, like Philips Hue app or Hue-TAP, I would like the status in Domoticz to be changed. The status changes, but it seems only visual, not in the database. This makes it unable to use the state of the hue lights in scripts. (like, if hue is turned off, also turn off other lights). I got this working, but I have to check the status in the hue bridge every minute, I want it to work without the workaround.

I have the same problem. Hoping for better Philips Hue support in Domoticz in the future.

Now i'm using a script with Curl that gives me true/false whenever a hue bulb is on/off in scripts.

[irisdc]

I have exactly the same problem as I would like to have real-time information about the a Hue light triggered by a physical switch. Will this be foreseen? Thanks in advance.

[MaXa]

Very interesting topic. Stumbled upon the same issue this evening. I bought the Philips HUE light with the Wireless light dimmer remote combi. Since the dimmer is not detected directly in Domoticz due to protocol limitations of HUE, I do not have the ability to switch my other lights or hardware with it (like Applamp lights) over Domoticz. My idea was the almost the same like you guys. I Have a bunch of sleeping room ligths Applamp (milight) together with the Philips HUE light in this room. My idea was to switch all lights with this Philips Dimmer switch and link the Milights directly to the Philips HUE lamp with a Blockly event or LUA script. Somehting like: If milight off then set Milight off. However, this doesn't respond in LUA and in Blockly. Only when I switch the Philips HUE light directly over the Domoticz interface, the other lights switch off as well. Turn Philips HUE off with HUE switch, doesn't trigger any activitity. Seems like something is completely ignored when switching lights from external sources besides Domoticz. Will do further investigation...

Now i'm using a script with Curl that gives me true/false whenever a hue bulb is on/off in scripts.

I have the same issue here, I want to use the states in Lua scripts but the status is not updated. I have changed one of my Hue Lights to an off/on switch instead of dimmer but that status gets only updated if I use the Domoticz interface. If my Domoticz scene (which is using a bash script to turn the correct Hue scene on) is turned on the status in Domoticz does not get updated. So the "last seen" of the switch displays correct, but the log of the switch doesn't display all changes. Also if you want to use the values in events or scripts it does not work as expected. See these topics:
viewtopic.php?f=6&t=5541&p=66686&hilit= ... vel#p66686
viewtopic.php?f=6&t=8745&p=64448&hilit= ... vel#p64448

So better Philips Hue support in Domoticz would be highly appreciated! In the mean time I will try to figure something out based on the suggestions in this topic.

@Kjakan: can you share the script you use with Curl?

[rgroothuis]

+1 for better support. I've the same problems with my Hue bridge. Published on a different thread already.

[Kjakan]

@Kjakan: can you share the script you use with Curl?

Sure. I'm still learning lua and programming so it could be better ways to do this.

You need to download dkjson.lua from http://dkolf.de/src/dkjson-lua.fsl/home and put it in "/usr/local/lib/lua/5.2" folder.

Code: Select all

local HueBridgeIP = "192.168.XX.XX"
local HueBridgeAPI = "XXXXXXX"

-- Function for checking Philips Hue On/Off state
function GetHueState(light_id)
	local json = require ("dkjson")
	local tmpfile = '/tmp/hueLight_'..light_id..'.txt'
	os.execute('curl -s http://'..HueBridgeIP..'/api/'..HueBridgeAPI..'/lights/'..light_id..' > '..tmpfile)
	local file = io.open(tmpfile)
	local content = file:read()
	local obj, pos, err = json.decode (content, 1, nil)
		if err then
			print ("Error:", err)
		else
			hue_state=(obj.state.on)
		end
	file:close()
	os.execute('rm -f '..tmpfile..'')
	--print (content)
	return (hue_state)
end

commandArray = {}

local hue_light1 = GetHueState(1) -- Get state from hue bulb id 1
local hue_light2 = GetHueState(2) -- Get state from hue bulb id 2
		
if hue_light1 == false then
	print("Hue light 1 is Off")
elseif hue_light1 == true then
	print("Hue light 1 is On")
end

if hue_light2 == false then
	print("Hue light 2 is Off")
elseif hue_light2 == true then
	print("Hue light 2 is On")
end

return commandArray

Change hue bridge IP and hue bridge API.
This example will get true/false state from Hue lights with id 1 and 2.

@Kjakan: can you share the script you use with Curl?

Sure. I'm still learning lua and programming so it could be better ways to do this.
....

Thanks! I used your example and altered it a bit. I do the check only on one light, when it is off but the state (switchlog/otherdevices table) in Domoticz is not correct it gives the same command again through the script. This seems to work for how I want to use it. Below is the script I use now:

Code: Select all

-- ~/domoticz/scripts/lua/script_time_HueState.lua

    local HueBridgeIP = "192.168.x.x"
    local HueBridgeAPI = "username"

    -- Function for checking Philips Hue On/Off state
    function GetHueState(light_id)
       local json = require ("dkjson")
       local tmpfile = '/tmp/hueLight_'..light_id..'.txt'
       os.execute('curl -s http://'..HueBridgeIP..'/api/'..HueBridgeAPI..'/lights/'..light_id..' > '..tmpfile)
       local file = io.open(tmpfile)
       local content = file:read()
       local obj, pos, err = json.decode (content, 1, nil)
          if err then
             print ("Error:", err)
          else
             hue_state=(obj.state.on)
          end
       file:close()
       os.execute('rm -f '..tmpfile..'')
       --print (content)
       return (hue_state)
    end

    commandArray = {}

    local hue_light1 = GetHueState(5) -- Get state from hue bulb id 5
          
    if hue_light1 == false then
       print("Hue light 1 is Off")
	   if otherdevices['Hue Staande Lamp']== 'On' then 
		  commandArray['Hue Staande Lamp']='Off'
	   end
    elseif hue_light1 == true then
       print("Hue light 1 is On")
	   if otherdevices['Hue Staande Lamp']== 'Off' then 
		  commandArray['Hue Staande Lamp']='On'
	   end
    end

    return commandArray

I had the same HUE update problem in Domoticz.
As a workaround I created a simple shell script to update the status of HUE lamps in Domoticz (similar as the lua scripts from previous posts).
I tested the script on a Raspberry pi.

Code: Select all

#!/bin/bash
# 
# Replace <ip hue bridge> with the ip address or hostname of your HUE bridge
# Replace <username> with the username that corresponds with your HUE bridge
# Replace <ip domoticz> with the ip address or hostname of your Domoticz system
#
# MYARR contains the HUE light numbers (used in the Philips HUE app) that correspond with the IDX numbers (used in Domoticz) in the form [HUE_LIGHT_NR]=IDX_NR
# For me, HUE light 1 corresponds with IDX 38, HUE light 2 corresponds with IDX 39 etc.
#
declare -A MYARR=( [1]=38 [2]=39 [5]=42 [6]=43 [7]=44 )
for i in ${!MYARR[@]}; do
  HUE_PROPS=$(curl --silent "http://<ip hue bridge>/api/<username>/lights/$i")
  grep '{\"state\": {\"on\":false' > /dev/null 2>&1 <<< "$HUE_PROPS"
  if [ $? -eq 0 ]; then
    curl --silent --output /dev/null "http://<ip domoticz>:8080/json.htm?type=command&param=switchlight&idx=${MYARR[$i]}&switchcmd=Off"
  fi
  grep '{\"state\": {\"on\":true' > /dev/null 2>&1 <<< "$HUE_PROPS"
  if [ $? -eq 0 ]; then
    curl --silent --output /dev/null "http://<ip domoticz>:8080/json.htm?type=command&param=switchlight&idx=${MYARR[$i]}&switchcmd=On"
  fi
done

Save above script somewhere on your filesystem (e.g. /home/pi/crontab/updateHueState.sh)
Make the script executable using the command chmod +x /home/pi/crontab/updateHueState.sh
You can easily test the script. Use your HUE tap or the Philips HUE app to turn one or more HUE light on, and execute the updateHueState.sh to update the status in Domoticz accordingly.

Calling the script each minute can be done by calling it from a cronjob. You can create such a cronjob by editing your cronjob file using he command cronjob -e
Add the following line:
* * * * * /home/pi/crontab/updateHueState.sh
This will call your script each minute.

I had running my hue lights a couple of months, but suddenly it was not working anymore? on/Off with hue app works fine.

I had this, with a bash script:

On code:

Code: Select all

curl -s -H "Accept: application/json" -X PUT --data '{"on":true, "sat":153, "bri":122,"hue":7294}' http://192.168.1.161/api/newdeveloper/lights/1/state ;

Off code:

Code: Select all

curl -s -H "Accept: application/json" -X PUT --data '{"on":false}' http://192.168.1.161/api/newdeveloper/lights/1/state ;

API debug console give the following result on url: api/newdeveloper/lights/1/state

Code: Select all

[
    {
        "error": {
            "type": 3,
            "address": "/lights/1/state",
            "description": "resource, /lights/1/state, not available"
        }
    }

Anyone a idea to make it working again?

[Bikey]

I think you now must a bridge generated user-key instead if the name.
See: http://www.developers.meethue.com/docum ... ng-started

Currently it is possible to create your own usernames in the bridge (e.g. “newdeveloper”), however, this option will be removed in future bridge versions, so we need to use the randomly generated username that the bridge creates for you.

[RichardBokker]

Thnx, that did the trick. Scripts are working now when i run them directly from Putty.

But the dummy switch what activates the on and off switch is not working, scripts seems not to be activated.. hmmz.
