slack-led

Slack LED toggle switch with Raspberry Pi. Listens for a turn word, and then turns a LED on or off.

Simple example on how to interact with Raspberry Pi via a Slack team/channel.

Requirements

This is meant to be used with Raspberry Pi, tested on Raspbian Jessie. Also requires Node.js 0.12 to latest

Installation

# clone repo to your local directory via ssh
$ git clone git@github.com:gabrielboliveira/slack-led.git

# or via https
$ git clone https://github.com/gabrielboliveira/slack-led.git

# cd to directory
$ cd slack-led

# and then install npm dependencies
$ npm install

Usage

First, run the script on the Raspberry Pi:

# build
$ npm run build

# and then run it
$ npm start

# if you need to change GPIO or PORT just add ENV variable before the npm start
$ PORT=65000 GPIO=15 npm start
# default: PORT=3000 GPIO=14

Remember that you must have the port opened and forwarding to your Raspberry Pi on your router or firewall, if applicable.

Configure a Outgoing Webhook on your Slack team.

• Channel: the channel you want to listen the words.
• Trigger word(s): turn
• URL: http://{your-ip}:{port-chosen}/led. Example: http://123.456.789.123:3000/led

All other configurations you can choose your own. For example, I changed the name to Raspberry Pi and downloaded the Raspberry Pi Foundation logo from their website. (Remember that Raspberry Pi and their logo is a Raspberry Pi Foundation Trademark.)

Then it should be all working. Test it by typing turn on and turn off on the channel you chose.
