homebridge-gpio-rgb-ledstrip

RPi GPIO based LED Strip plugin for Homebridge

Due to all the changes and updated that have occured in Homebridge since the original release of this plugin, i decided to replace its core to extend its usability and compatibility. This plugin now relies on pi-blaster.js which you need to install beforehand.

Originally inspired by GiniaE/homebridge-gpio-ledstrip

Installation

1. Install pi-blaster.
2. Update pi-blaster DAEMON_OPTS configuration under the path /etc/default/pi-blaster to enable your specific pin layout (instructions).
3. Install [homebridge-gpio-rgb-ledstrip] directly from Homebridge Plugin Page or by running sudo npm install -g homebridge-gpio-rgb-ledstrip.
4. Update your configuration file. See sample config.json snippet below. Remember to use BCM GPIO layout.

To identify the correct pin configuration, have a look at the following layout

P.S: if pi-blaster seems not to work (e.g running the command 'echo "$PIN=1" > /dev/pi-blaster' doesn't yield the desired output), try restarting manually the service with root privileges

Configuration
