Lifx Bulb Scrape.Put

[Foggy]

Hi All,

I could do with some help getting my Lifx bulb to work.
You can control using an HTTP API. http://api.developer.lifx.com/docs/set-state

This is my entry with my api key changed.

Hi All,

You can control using an HTTP API. http://api.developer.lifx.com/docs/set-state

This is my entry with my api key changed.

The basic syntax for your command looks correct based on the documentation LIFX provides. The error you're getting suggests there's a problem with the access token you're using.

You mention that you're using your "API key". Is it possible you're using an API key instead of the access token, or are those the same thing?

Per the site:

All requests require an OAuth 2 access token. You can generate an access token in your account settings.

Thank you for your quick reply.

Sorry. I used the wrong terminology API Key = Token.
Just tried creating a new token and used it in the "Try it out" section of http://api.developer.lifx.com/docs/set-state and it works.
Then just copied into my LCB.

Best wishes.

James.

Try putting something (anything) in the password field. 

The reason I suggest this is that VC looks at the username and password and if either of them is blank it won't add the credentials to the request.  I guess this was based on an erroneous assumption on my part.  Either that or this api is using credentials incorrectly.  In any case I will update the next release so that credentials are sent as long as there is a username specified.

If that doesn't work you can try adding the authorization as a header as follows:

<?xml version="1.0" encoding="utf-16"?>
<!--VoxCommando 2.2.0.9-->
<command id="-1" name="Actions copied from LCB">
  <action>

      <param>{"power": "on"}</param>
      <param />
      <param />
      <param>application/json</param>
      <param>Authorization: Bearer YourAccessToken</param>
    </params>
    <cmdRepeat>1</cmdRepeat>
  </action>
</command>

[Foggy]

Thank you for your suggestion.

That did not appear to work.

However I did try on my Linux machine the suggested cURL command and I am getting what looks like a valid response. So I am happy that I have the correct token in my LCB

I have xxxx'd out my token.

[jitterjames]

I suggested two different things.

[Foggy]

Yes sorry. Mails got crossed. I'll try your header.

Best wishes.

James.

[Foggy]

Yep. Adding the authorisation as a header worked.

Thank you very much.


Best wishes.

Great. Thanks for reporting back.

Hello again.

Whilst this now works very well within Voxcommando. There are some times when I am working at my computer and I don't have my Amulet near by. Is it possible to run a Voxcommando command from within a Windows *.bat file ie from the Windows command line.

Hi Foggy,

Your best bet is probably to generate an event which can be used to trigger the command.  There are a few ways to do this.  You could use the simple web server which is part of the TCP plugin, or you can use TellVoxCommando.exe if you want to be able to test different things without using a microphone.

If you want to send actions or events to VoxCommando from the command line the best way to do that is probably to use the UDPSender.exe command line utility which you can download as part of the "Extra utilities" available on the download page.

For more info and examples see:

http://voxcommando.com/mediawiki/index.php?title=API_Application_Programming_Interface

http://voxcommando.com/forum/index.php?topic=414.msg2815#msg2815

By the way, I think it is usually better to copy and paste commands from the command tree editor instead of the LCB (macro editor), that way we can see the complete commands with the input phrases, payloads, events etc.  In this case it probably doesn't really matter but I thought I should mention it for future reference.

[Foggy]

Many thanks James.

Thank you for the links. I think UDPSender.exe is worth a look at.
Looking through the forum link you gave I am confused if I should use (Send actions or events) or if I can call the action /command directly?

If it can. Can you assist with the syntax? I would move the UDPSender.exe into c:/
Please see corrected command.

How do you currently trigger this command?

Although you could duplicate that exact action in your UDP command line message, the usual way is to send the voice command or event name for the command.

Below, I've created a voice command and an event trigger for your command. Either of these could be used in your command line message:

Code Select Expand

<?xml version="1.0" encoding="utf-16"?>
<!--VoxCommando 2.2.1.4-->
<command id="34" name="http Scene" enabled="true" alwaysOn="False" confirm="False" requiredConfidence="0" loop="False" loopDelay="" loopMax="" description="">
  <action>
    <cmdType>Scrape.Put</cmdType>
    <params>
      <param>https://api.lifx.com/v1/scenes/scene_id:12d75....................REMOVED/activate</param>
      <param />
      <param />
      <param />
      <param>application/json</param>
      <param>Authorization: Bearer c6f4a4....................REMOVED</param>
    </params>
    <cmdRepeat>1</cmdRepeat>
  </action>
  <phrase>trigger Lif X scene</phrase>
  <event>lifx-scene</event>
</command>

command line option 1:

Code Select Expand

udpsender.exe 33000 "vc.triggerevent&&lifx-scene"

option 2:

Code Select Expand

udpsender.exe 33000 "vc.tellvox&&trigger Lif X scene"

You could also re-create the syntax of that specific Scrape.Put action, but with all the parameters and long strings it seems prone to typos.

[jitterjames]

Although you can execute actions directly using the VC API you cannot execute commands directly.  In order to execute a command via the API you will either need to trigger it using an EVENT or using the VC.TellVox action which allows you to emulate a voice command.

I think the easiest way is to trigger an event.  Once you get the UDPSender working you should see the event appearing in your history window.  Then just click edit and drag the event from the history window to the command in your Command Tree Editor.  Save and close the Command Tree Editor and then the event will trigger the command.
