[SCENE] IFTTT Webhooks

[Ros 22]

Hi guys,

 

I thought to share a simple scene that can be called to trigger any IFTTT action via the Webhooks service.

You can call this scene from any other scene or VD just like the smart message hub i.e. fibaro:startScene(sceneID ,{'TriggerID', 'Value1', 'Value2', 'Value3'})

 

With this you can do pretty much anything IFTTT is capable of. Some examples of what I am using it for below:

- Send myself a message from HC2 to my Facebook Messenger

- Control my geothermal heatpump (Nibe heatpumps support IFTTT)

- Turn on/off main and guest network on the Asus router (also supports IFTTT)

 

But again, you can use this to trigger pretty much any IFTTT applet.

Credits:

 - The logbug function is from Zoran's code (he packs it into all his creations)

 -  fibaro:args() inspired by Frank's smart message hub

 

 

--[[
%% properties
%% events
%% globals
--]]

local deBug            = true
local args             = fibaro:args()
local TriggerID
local Value1
local Value2
local Value3
local http             = net.HTTPClient({timeout=3000})
local Key             = '<insert your IFTTT key here>'

 

if args[1] == nil then TriggerID     = '' else TriggerID     = args[1] end
if args[2] == nil then Value1         = '' else Value1         = args[2] end
if args[3] == nil then Value2         = '' else Value2         = args[3] end
if args[4] == nil then Value3         = '' else Value3         = args[4] end

 

if (fibaro:countScenes() > 1) then
  logbug('pink', 'The scene is already running')
  fibaro:abort()
end

 

function logbug(color, message)
  if deBug then
    for line in message:gmatch("[^\010\013]+") do
      local txt = line:gsub("([\038\060\062])",
        function(c)
          return "&#"..string.byte(c)..";"
        end)
      fibaro:debug(('<span style="color:%s">%s</span>'):format(color,txt))
    end
  end
end

 

function IFTTTWebhooks()
  http:request('https://maker.ifttt.com/trigger/'..TriggerID..'/with/key/'..Key, { 
      options={ 
        headers = {['Content-Type'] = 'application/json'},
        data = json.encode({value1=Value1, value2=Value2, value3=Value3}), 
        method = 'POST', 
        timeout = 3000 
      }, 
      success = function(response)
        logbug('yellow', response.status..' '..response.data)
    end, 
      error = function(error) 
        print('ERROR: '..error) 
      end 
    })
end

Edits: added the missing quotation marks (as per @tampiss)

Nice one  Thank you. Just a quick fix in Values

 

from fibaro:startScene(sceneID ,{'TriggerID', 'Value1, Value2, Value3'})

to fibaro:startScene(sceneID ,{'TriggerID', 'Value1', 'Value2', 'Value3'}) 

 

There were quotation marks missing in the example.

I use webhook of ifttt in action (then) part a lot to trigger different scenes by executing a php file on my vm.  @Ros your script looks the way around unfortunately I do not understand how to use it lol.  is it..

 

if fibaro:getGlobal('aaa') == "0" then

fibaro:startScene(webHookId)

end?

 

What are those TriggerID, value1 value2 etc use for?

 

Thanks!

If you read the Webhook documentation, it needs to know the TriggerID  - which action to launch and up to three values to feed parameters into the action being launched. Just read the Webhook documentation at IFTTT...

Hi @Ros man this can be a huge change of smart home infrastructure as long as internet is up.  I can imagine I can use your scene to control my retired smartthings hub even with different z-wave frequency devices...

 

I created an IFTTT recipe with webhook event 'push_test', then trigger ifttt notification as a test.

 

On HC2 I simply created a lua scene with 1 line,  fibaro:startScene(194 ,{'test_push', 'Value1', 'Value2', 'Value3'}), and run it 2 times. I got the below debug message from your scene though.

 

1) ERROR: Operation canceled - I can receive the notification

2) ERROR: Transport endpoint is already connected. - no notification received

 

Am I doing anything wrong?

Now taking it one level further: The above can trigger IFTTT, but the below is the best way I've seen so far to take an HC2 action triggered by IFTTT.

 

Many of us are concerned about the security of IFTTT Webhook accessing  HC2 via basic authentication. People have generally tried creating a new user and limiting the rights for that user. For those even more paranoid about security, there is another, more sophisticated solution (tried and tested):

• IFTTT Webhook sends commands to ThingSpeak channel via API
• ThingSpeak channel data insertion triggers a Matlab analysis app in the cloud. You can use this app to generate a mathematical encryption of the command you want to forward to HC2. Sky is the limit for encryption here (you can read the Cryptonomicon for insipartion:)
• ThingSpeak sends an HTTP API request to HC2 to trigger a scene with the encrypted command in the body of the request (to be used in fibaro:args())
• HC2 Scene processes takes the command from the fibaro:args(), decrypts it and takes appropriate actions

Here are the reasons this solution works:

• You have all the versatility of IFTTT
• You have the flexibility of ThingSpeak Matlab - you can post process and encrypt...
• On HC2 you only have to give the 'IFTTT user' the right to access that one scene that decrypts the command and takes action

Speed is ok - requests triggered by IFTTT take 2-4 seconds to be executed by HC2.

 

Unless Fibaro develops a genuine IFTTT service, the above is the most secure and versatile solution I've come across.

Also the Google Assistant integration of Fibaro is a joke. But with the above you can do anything you want with GA via IFTTT service - devices, scenes, global variables, all of it together, etc.

Hi @Ros, really nice stuff you created. Can you please detail the facebook messenger integration? 

What specific values do we need for 'TriggerID', 'Value1', 'Value2', 'Value3' ? 

startScene(sceneID ,{'TriggerID', 'Value1', 'Value2', 'Value3'})

Thanks.

Man, you've got to build an IFTTT applet with 2 services: if (webhook) then (facebook messenger). Just read a bit about how IFTTT works, especially the webhook service. You  can set any values you want there....

Thanks. I got it. It's really useful to have my notifications on facebook messenger too. Thanks again.

I am the only one having problem with facebook messenger? Since yesterday I cannot receive anymore messages over IFTTT. My personal IFTTT activity page is frozen since yesterday.

The scene debug is ok: [DEBUG] 13:43:45: 200 Congratulations! You've fired the Fibaro_to_Facebook event

I am having problem on ifttt without doing any changes recently. super slow response and occasionally 502 error.
