I did this.

I used the MMM-PIR-Sensor module and changed the following in node_helper.js:

From:

        if (data.indexOf("0x120002") !== -1)
          exec("/opt/vc/bin/tvservice --preferred && chvt 6 && chvt 7", null);

To:

        if (data.indexOf("0x120002") !== -1){
          exec("/opt/vc/bin/tvservice --preferred && chvt 6 && chvt 7", null);
          exec("python /home/pi/py-spidev/RPi-LPD8806/LED.py");
       }

and

From:

      exec("/opt/vc/bin/tvservice -o", null);

To:

      exec("/opt/vc/bin/tvservice -o", null);
      exec("python /home/pi/py-spidev/RPi-LPD8806/off.py");
       }

Note that in the first from - to there is a “)” missing in the original code that you will need to fix. Also note that as soon as the module gets updated if you hack the code like I did above it will be wiped out when you update.

I used these only because they were incredibly cheap and I originally started out looking at MMM-PiLights which uses the same LPD8806 type:

I used this python code:

For those just joining, I was able to get this to work using the Google OAuth desktop option and the V2 token generator that hermanho made at the link below

I ordered these:

FYI - for those that are reading this in the future, make sure that your power supply ground is grounded to the RPi ground. That tripped me up.

The answer to my question is to add the sendNotification line in the MMM-PiLights.js as follows:
From:

	socketNotificationReceived: function(notification, payload) {
		if (notification === "USER_PRESENCE"){
			this.sendNotification(notification, payload)
		}

To:

	socketNotificationReceived: function(notification, payload) {
		if (notification === "USER_PRESENCE"){
			this.sendNotification(notification, payload);
                        this.sendNotification('PILIGHTS_SEQUENCE', 'blue_pulse');
		}

Unfortunately I have realized that I want to do something more elaborate then the PiLights module allows so instead I am now calling a python script instead.

Different strips have different ways they need to be programmed. Some have faster refresh rates than others.

Most people will suggest ADA102 for beginners. The strips I linked to are LPD8806. As I mentioned previously the only reason I bought those ones is that MMM-PiLights was programmed to use them.
