Google Home - Intercom - using google-home-notifier

Here's an intercom i put together using the following:

• google-home-notifier -- created by noelportugal  https://github.com/noelportugal/google-home-notifier
• php (code is below)
• IFTTT maker

First install and run google-home-notifier as instructed on his page (linked above)
I installed this on my Pi

When you start up the example.js as mentioned, it will give the following when it is ready to receive requests:

POST "text=Hello Google Home" to:
        http://localhost:8080/google-home-notifier
        https://*******.ngrok.io/google-home-notifier
    example:
    curl -X POST -d "text=Hello Google Home" https://*******.ngrok.io/google-home-notifier

For my application, I use the line referencing localhost info but changed localhost to the server it was running on since my php code is on a different box.

http://localhost:8080/google-home-notifier
to
http://ip_of_pi:8080/google-home-notifier

Next, create a php script similar to mine below:

change ip_of_pi in the code to the ip of where you installed google-home-notifier


The $url in the code was just for this write up but your should use an https connection and credentials since this is externally accessible

announce.php

    $url = 'http://ip_of_pi:8080/google-home-notifier';
    $post_data = "text={$_GET['sayWhat']}";
    $ch = curl_init();
    curl_setopt($ch,CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
    $return = curl_exec($ch);
    curl_close($ch);




Now create an IFTTT applet at https://ifttt.com/

create a New Applet

Choose + this

Choose the Google Assistant service

Choose the phrase with a text ingredient

Enter the desired phrase to kick off the request

and use $ where you want your input.

You may also choose a custom response -- including

the $ if you want the phrase repeated in the response

Now choose + that

Choose the Maker action service 

web request

Enter the url where your php code can be reached (needs to be externally accessible)

{{TextField}} is the $ item received as part of the + this from above
Method: GET
Content Type: text/plain

Click Finish to save you new applet 

If everything went well it should look like the following

Create a second js file and a second IFTTT applet for calling the 2nd (or more) room(s)
