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:

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.

I just updated to the latest And my photos stopped displaying. Anyone else have this issue?

I just get Loading…

I am having trouble with the excludedEvents parameter in the calendar module. I can get some words to filter but not others. For instance I if I have the following two events on the calendar:

School Early Dismissal
Roger’s Special - Art

If I enter ‘Early’ in the excludedEvents array then as expected the School Early Dismissal goes away. If I enter ‘Roger’ or ‘Art’ or ‘Special’ then I can’t get the second event to filter out.

I have 3 calendars. I tried eliminating all but the one that pulls the “Roger’s Special - Art” event and still no luck. I am starting to think that there is something about that calendar ics that prevents events from being filtered? Is this possible?

		module: "calendar",
			header: "Calendar",
			position: "top_left",
			config: {
				maxTitleLength: "30",
				timeFormat: "absolute",
				nextDaysRelative: true,
				titleReplace: {'SPECIAL MEETING':'meeting'},
				displaySymbol: false,
				//maximumNumberOfDays: "62",
				fade: false,
				excludedEvents: ['Special'],
				calendars: [
					{
						
						// symbol: "calendar-check-o ",
						url: "webcal://www.calendarlabs.com/templates/ical/US-Holidays.ics",
						maxTitleLength: "17"
					},

@Sean looking forward to it. Thanks again for an awesome module.

@sdetweil I now have a cron job to turn the monitor off. Is that what you mean by “sleep”? Does that stop the API requests?

First, thanks for a great module. Its greatly appreciated.

Is there a way to prevent API requests during certain time periods? I have 14000 photos in an album that is only going to grow with time which is going to kill my API requests but I don’t need requests to take place at 2AM for instance.

Mine is also hosting PiHole and also doing a cron job every hour to test ISP download speeds

I don’t have any processor intensive modules installed.

@slametps

The maximumEntries setting now applies to each calendar rather than globally. So if you have 5 calendar URLs then you get 50 listings (if the default is set to 10). Before the change it would show the most recent 10 events from all of your calendars.

You didn’t miss it. It is a change with the most recent update.
