homebridge-gpio-relay

Control your low-active relays using Homebridge

Currently, this plugin controls your low-active relays (like from SainSmart), which are connected to your Pi's GPIO Pins. This way you can switch your relays using HomeKit and Siri.

Installation

1. Install Homebridge using sudo npm install -g homebridge (if not already installed)
2. Install this plugin sudo npm install -g homebridge-gpio-relay
3. Update your configuration file - find below
4. Install the forked version of gpo-admin:

git clone git://github.com/jamesblanksby/quick2wire-gpio-admin.git
cd quick2wire-gpio-admin
make
sudo make install
sudo adduser $USER gpio

Configuration

Configuration sample:

   "accessories": [
   	{
   		"accessory": "relay",
   		"name": "My relay no 2",
   		"pin" : 3,
   		"duration" : 5000
   	}
   ]

This example would switch on the relay, connected to GPIO 3. After 30 seconds the relay will be switched off again.

Fields:

Key	Value-description	required / optional
accessory	Must always be "relay"	required
name	Can be anything	required
pin	The physical pin which is connected to your relay, NOT the GPIO nummer. For example type in "3" to control GPIO 02 with a Raspberry Pi 3.	required
duration	The duration in milliseconds until the relay should be deactivated. Enter 0 or leave blank turn off this functionality.	optional, default: 0 (turned off)

Testing

I am using this plugin to control a SainSmart 4-channel relay module. The specialty is, that the 4-channel relay doesn't need a separated power supply in addition to the 5V comming from the Raspberry Pi's GPIO pin. If you would like to control a larger relay (no matter which plugin you are using) keep in mind to connect an additional power supply to your relay board (for example 12V).

Warning / Disclaimer: Electrical wiring should be done by a specialist. This plugin is developed and tested as good as I can. I do NOT take any responsibility for any damages caused by the plugin.
