LIFX Support

[superczar]

Is it possible to add LIFX support ?
I am working on integrating the different interfaces I need to use for my house through Domoticz but missing out on LIFX and Wemo at the moment

[superczar]

Solved - In case anyone is interested, i can provide a detailed answer
There are multiple LIFX control libraries available on the net
I fiddled with a Perl library but finally got a reliable solution with lifx-python
Its far from perfect but I could add the LIFX as a dummy switch and now have easy on/off toggles as well as color scenes under scenes

I like to use Domoticz, It's very usefull for me. But one thing is missing, the LIFX intégration.
I'm very interested to receive the procedure to implement LIFX.
Thanks,

Created a basic wiki page with steps

Great, It's work fine.
One thing is missing it's the possibility to access the bulbs individually

[Derik]

Nice..
Only are these better then a HUE?

Very expensive bulbs....?
The reason for that?

[superczar]

Great, It's work fine.

You can change the name of the bulbs on your network to LIFX1, LIFX2 and so on after which you should be able to call individual bulbs

Nice..
Only are these better then a HUE?

The bulb hardware is better than HUE - 17 W vs 9 W so significantly brighter
Also, the ability to manage saturation independently allows for a far better control on the light spectrum

The official software for the HUE is however far better , the LIFX team has really botched up the apps

[Derik]

Do i need other hardware?
Or only a bulb?

The best place to buy?

I don't see where I can insert in the scripts the name or mac adr. of the bulbs.
When I execute example_intro.py :
at lights = lifx.Lifx() : it's give the adr. of one bulb
at print(lights.get_colours()) : it's give the parameter of same bulb
at print(lights.get_labels()) : it's give me the name of all bulbs

So I will continue to investigate.

You can check new features will come: http://support.lifx.co/hc/en-us/article ... X-2-0-apps
The LIFX bulbs are WIFI devices and there is no need of bridge or something like that. They join an exiting WIFI network. It's very easy to install.

You can buy directly at http://store.lifx.co/ but you risk to pay customs fee. You have also in NL http://www.coolblue.nl/

New user of Domoticz with a lifx bulb... I've been playing with the new cloud api and have managed to successfully setup a dummy dimmer that works flawlessly.

I've created a dummy switch based on lightwaverf called Lifx and the following lua script (named script_device_Lifx.lua) will allow the control of on/off & dimming:

Code: Select all

commandArray = {}

DomDevice = 'Lifx'
lifxlabel = '<INSERT THE LABEL OF THE BULB YOU WANT TO CONTROL HERE>'
apikey = '<INSERT YOUR OWN API KEY HERE>'

 if devicechanged[DomDevice] then
   if(devicechanged[DomDevice]=='Off') then
   print ("Turning off " .. DomDevice);
   runcommand = "curl -H \"Authorization: Bearer " .. (apikey) .. "\" -XPUT https://api.lifx.com:443/v1beta1/lights/label: .. (lifxlabel) .. "/power.json?state=off";
   os.execute(runcommand);
   return commandArray
   elseif(devicechanged[DomDevice]=='On') then
   print ("Turning on " .. DomDevice);
   runcommand = "curl -H \"Authorization: Bearer " .. (apikey) .. "\" -XPUT https://api.lifx.com:443/v1beta1/lights/label: .. (lifxlabel) .. "/power.json?state=on";
   os.execute(runcommand);
   return commandArray
   else
   DomValue = (otherdevices_svalues[DomDevice]);
   end
   CalcValue = DomValue / 31.25;
   print ("Dimming "  .. (DomDevice) .. " to " .. (CalcValue) .. " ");
   runcommand = "curl -H \"Authorization: Bearer " ..
(apikey) .. "\" -XPUT https://api.lifx.com:443/v1beta1/lights/label: .. (lifxlabel) .. "/color.json?color=brightness:" .. (CalcValue) .. " ";
   os.execute(runcommand);
 end
return commandArray

It's pretty crude, but works a treat.

You'll need to get your own api key from chendo @lifx in order to use this functionality. See here: https://github.com/chendo/lifx-http/iss ... t-72760322

I'd like to take this further & implement a colour wheel... is there any way of creating a dummy switch with a colour wheel in domoticz? Failing this is there any decent documentation to allow me to write my own hardware device?

[mattc]

Added the above to the wiki

[Pi314]

Now is possible to generate your own api key (token) yourself by logging into https://cloud.lifx.com/ and going to <your email> -> Settings.

@mattc
They are some typo error , corrected lines:

runcommand = "curl -H \"Authorization: Bearer " .. (apikey) .. "\" -XPUT https://api.lifx.com:443/v1beta1/lights/label: .. (lifxlabe) .. "/power.json?state=off";
runcommand = "curl -H \"Authorization: Bearer " .. (apikey) .. "\" -XPUT https://api.lifx.com:443/v1beta1/lights/label: .. (lifxlabel) .. "/power.json?state=on";
runcommand = "curl -H \"Authorization: Bearer " .. (apikey) .. "\" -XPUT https://api.lifx.com:443/v1beta1/lights/label: .. (lifxlabel) .. "/color.json?color=brightness:" .. (CalcValue) .. " ";

in the wiki:
domoticz/scripts/lua/script_device_Lifx.lua

[mattc]

that's weird, I just copy pasted my working code. Thanks for correcting it.

I'd love to see a native hardware device for lifx in domoticz using the api, I'm sure it could be a quick adaptation of the Hue stuff. I had a quick look but looks too involved for me

[phitar]

Wonderful being able to include the LIFX lights ! Thank you so much.

2 minor points:
I had an issue with Lamp Names including spaces. Removing them or replacing them with %20 enabled the scripts.
The typos are still present, missing ¨ after the XPUT parameter in the wiki.

[l00pz]

I would also like to control the LIFX lights with Domoticz, but I`m unable to get them working.. I think it has something to do with me using the wrong script, but where do I need to put the " that is not present in the Wiki according to the last post?

Is the correct line: runcommand = "curl -H \"Authorization: Bearer " .. (apikey) .. "\" -XPUT https://api.lifx.com:443/v1beta1/lights/label: .. (lifxlabe) .. "/power.json?state=off";
Or is it: runcommand = "curl -H \"Authorization: Bearer " .. (apikey) .. "\" -XPUT "https://api.lifx.com:443/v1beta1/lights/label:" .. (lifxlabe) .. "/power.json?state=off";

[phitar]

I thought I had corrected it in the wiki and can't seem to find a difference with what I have.
The log file may give you clues about what's wrong.
The problem I kept on having is the cut&paste function removed some " from the script, specifically those before " ..(lifxlabel) .. "
Here is the script I am using and that is working for me.
Do you LIFX devices have very simple names ?



commandArray = {}

DomDevice = 'DEVICE NAME'
lifxlabel = 'LIFX LABEL'
apikey = 'LIFX API KEY'

if devicechanged[DomDevice] then
if(devicechanged[DomDevice]=='Off') then
print ("Turning off " .. DomDevice .. " named " .. lifxlabel);
runcommand = "curl -H \"Authorization: Bearer " .. (apikey) .. "\" -XPUT https://api.lifx.com:443/v1beta1/lights/label: ..(lifxlabel) .. "/power.json?state=off";
os.execute(runcommand);
return commandArray
elseif(devicechanged[DomDevice]=='On') then
print ("Turning on " .. DomDevice .. " named " .. lifxlabel);
runcommand = "curl -H \"Authorization: Bearer " .. (apikey) .. "\" -XPUT https://api.lifx.com:443/v1beta1/lights/label: ..(lifxlabel) .. "/power.json?state=on";
os.execute(runcommand);
return commandArray
else
DomValue = (otherdevices_svalues[DomDevice]);
end
CalcValue = DomValue / 31.25;
print ("Dimming " .. (DomDevice) .. " to " .. (CalcValue) .. " ");
runcommand = "curl -H \"Authorization: Bearer " .. (apikey) .. "\" -XPUT https://api.lifx.com:443/v1beta1/lights/label: .. (lifxlabel) .. "/color.json?color=brightness:" .. (CalcValue) .. " ";
os.execute(runcommand);
end
return commandArray

My LiFX Bulb is named "Woonkamer", and the Switch in Domoticz is named Domoticzlifx

Here's an upload of my working script... hopefully will avoid the cut/paste weirdness going on!

Oh, and take your key out of the post above.... your letting anyone control your lights by publishing it!

[l00pz]

Sorry for the late reaction, but with you`re script it seems te be working One sidenote though, I keep getting the 32256 error in the Log viewer. Any idea what that could be?
And another question, what type of Switch do I need to add to get the dimming function working?
