Alexa unRAID voice control How-To

[Squid]

Here is how to get Alexa to control your server (IE: have Alexa start up a VM / docker container etc).  This is all geared towards using a free Dropbox account as the cloud server and Alexa, but the concept would be the same for any other cloud storage providers (provided you can mount the cloud storage location) and Google Assistant.  You probably also need to use the same login as you would for your Alexa account.  (I just used "login via google" for everything listed here, which matches my alexa account)

 

• Sign up for a free account at https://www.dropbox.com/basic
• From the Apps Tab, search for Dropbox and install it. 

 

 

• You must however change the host path for the Data Files from it's default of /mnt/user/Dropbox to instead be /mnt/cache/Dropbox (dropbox will not work if it's not pointed directly at a drive), with an access mode of RW:SLAVE

 

 

• Start the dropbox application, and view the logs for it.

 

 

• In the logs there will be a line similar to

 

 

• Go to the URL and connect the server to your account
• Set Dropbox to autostart
• Go to https://ifttt.com/join and create a free account
• Go to Create

 

 

• Click the Plus sign

 

 

• Select Amazon Alexa

 

 

• Select Say A Specific Phrase

 

 

• Tell Alexa what to listen for and create the trigger

 

 

• Click the Plus Sign

 

 

• Choose Dropbox and create a text file

 

 

• In the box, the "content" is the command to be executed.  If you're running multiple commands, then I would suggest executing them as a script ie: content would be 

/bin/bash /boot/my_scripts/mytestscript.sh

• Set the dropbox folder path to be unraid_actions  Then click create action  (In this example, we're just going to write "This is a test" into the syslog

 

 

 

• Using the User Scripts plugin (if already installed, then make sure that it's up to date), set up the following script to run at First Array Start Only

 

#!/usr/bin/php
<?
  for ( ;; ) {
    exec("inotifywait /mnt/cache/Dropbox/unraid_actions > /dev/null 2>&1",$out,$err);
    if ($err) { sleep(10); continue; }
    foreach (glob("/mnt/cache/Dropbox/unraid_actions/*.txt") as $file) {
      exec("logger ".escapeshellarg("Executing Voice Command ".file_get_contents($file)));
      passthru("/bin/bash ".escapeshellarg($file));
      unlink($file);
      for ( ;; ) {
       sleep(1);
       if ( ! is_file($file) ) break;
      }
    }
  }
?>

 

• Enter in the following command at the terminal  (If you don't do this, then it will miss the first trigger ever given)

mkdir -p /mnt/cache/Dropbox/unraid_actions

• Reboot the server and test what you've created

Quote

Alexa, trigger this is a test

 

Apr 23 08:40:27 unraidA root: Executing Voice Command logger this is a test
Apr 23 08:40:27 unraidA root: this is a test

 

Success!

 

Now you can create any given command you want for Alexa to be able to execute on your server.  IE: you can start a VM with the appropriate virsh commands, start a docker container, etc etc etc.  Enjoy

 

 

DANGER ZONE:

 

DO NOT USE A DROPBOX where other people have write access to it (ie: make sure that no one else can place a file into unraid_actions).  This script will execute ANY file placed into unraid_actions, and if/when your kids get annoyed at you, there is nothing stopping them from deleting the contents of your array.  Only use drop box where you are in 100% complete control of.

 

To avoid this problem, you could expand the user scripts script to actually read what's in the file (say the contents are Start VM) and then it issues the appropriate command itself.  I'll leave the customization up to you guys.  Something akin to

#!/usr/bin/php
<?
  for ( ;; ) {
    exec("inotifywait /mnt/cache/Dropbox/unraid_actions > /dev/null 2>&1",$out,$err);
    if ($err) { sleep(10); continue; }
    foreach (glob("/mnt/cache/Dropbox/unraid_actions/*.txt") as $file) {
      $command = trim(file_get_contents($file));
      exec("logger ".escapeshellarg("Executing Voice Command $command"));
      switch ($command) {
        case "test":
          exec("logger this is a test");
          break;
        case "start VM":
          exec("virsh.....");
          break;
        case "start plex":
          exec("docker start plex");
          break;
        default:
          exec("logger ".escapeshellarg("unknown voice command $command"));
          break;
      }
      unlink($file);
      for ( ;; ) {
        sleep(1);
        if ( ! is_file($file) ) break;
      }
    }
  }
?>

Hopefully I didn't miss any steps    And also, don't delete the unraid_actions folder from your dropbox.  If you do this, then it will miss the first trigger given to Alexa

"Alexa, BEER ME."

Anyone got this or a similar solution for google assistant? I got wake on lan working (asus router + ifttt + google assistant) but now I'm looking to send the unRaid server to sleep in a similar fashion.

iffft has the same applets available for Google as it does for Alexa.   This was mostly a POC as I was curious (and bored)

Hi Squid, I actually used the "Dropbox-otherguy" mgutt's repo for this.. as i can't make the other work. 

I got into "Syncing..." in the container log but i don't receive my text file inside my share folder. any advise  ?

[Squid]

This was something I did 2 years ago on a whim and have never looked at it (or used it since)  Basic procedure I would think would remain the same.

Hi Squid, thanks. 

I actually tried removing the DROPBOX_SKIP_UPDATE value from the container settings. and made sure set the "Dropbox" share set to Cache setting to "No" and just tried restarting the container, and everything worked already. 

 

just circling back to share what was done to make the container work. 

 

Edit: for me this is very helpful because i don't have to do any WOL or VPN in the Server to turn on my windows VM. I can just let the kids know what to say to have the Windows VM start.  

thank you again for the guide.
