HAP-NodeJs-Accessories

Accessories I have created for HAP-NodeJs HomeKit Automation with a Raspberry Pi.

GarageDoorAutoClose_accessory.js

This is a variation of GarageDoorOpener_accessory.js for garage gates that open with a button press and automatically close after a set period of time. It also includes notifying HomeKit of the following garage door state: opening, open, closing, closed.

My apartment building has one of these kind of gates and I needed a way to handle the auto closing behavior.

The accessory is designed to be used with a relay board connected to a garage remote on the relay side, and Raspberry Pi GPIO pins on the signal side. I use a SainSmart 2-channel relay, but you can use any other relay board, just be aware of the polarity.

###Setup Modify the pin settings in the GarageDoorAutoClose_accessory.js file to match your setup.

//Define the pin number for the relay GPIO
//the rpio module uses the physical numbering scheme
//Pin 16 is GPIO 23
var pinNumber = 16;

Then modify the variables for each of the timeouts:

//Time in milliseconds to hold the garage open signal
var doorOpenButtonTimeout = 3000;

//Time in milliseconds it takes for the door to open 
var doorOpeningTimeout = 10000;

//Time in milliseconds that the garage door will stay open after opening, and before automatically closing
var doorAutoCloseTimeout = 30000;

//Time in milliseconds it takes for the door to close 
var doorClosingTimeout = 10000;

You must also install the rpio package for this accessory to work. Run the following in the root of your HAP-NodeJs directory to install rpio:

npm install rpio

DimmableLED_accessory.js

This lets you set the brightness of an LED directly connected to a Raspberry Pi GPIO pin.

Setup

Modify the pin settings in the DimmableLED_accessory.js file to match your setup.

//Define the pin number for the relay GPIO
//the pigpio module uses the GPIO numbering scheme
//GPIO 18 is Pin 12
var pinNumber = 18;

You must also install the pigpio package for this accessory to work. Run the following in the root of your HAP-NodeJs directory to install pigpio:

npm install pigpio
