Slack Bot with internet of things

This is a project of a slack bot, to automate your office/room/lab using some Raspberry Pi GPIO pins.

Set up your slack workspace

Go to https://slack.com/ . First you'll need to create a new slack workspace to use in this project(or just get the API token from a existing bot in the workspace). Then, go to https://my.slack.com/services/new/bot and choose a username for your bot.

After submit, we now have an API key. Copy this somewhere we'll need later.

Requirements

Now, on your Pi you'll need to install some dependencies:

Python3
pip3
python3-rpi.gpio

sudo apt-get install python3 python3-pip python3-dev python3-rpi.gpio -y

And then some packages:

pip3 install slackclient

pip3 install psutil

And download the repository:

git clone https://github.com/vitor-veras/slackbot_iot.git

Configuring the python file

After downloading slackbot_iot.py file there's some things you'll need to adapt to your bot, like your API token that we generated earlier.

slack_client = SlackClient("your-api-token-here")

In this next step, we fetch our bot User ID. We will use this later to know when somebody is talking to our bot. We keep it in slack_user_id.

user_list = slack_client.api_call("users.list") for user in user_list.get('members'): if user.get('name') == "your-bot-name": slack_user_id = user.get('id') break

Personalize

Now you can personalize your bot with some GPIO pins(any doubts about GPIO pins go to RPI.GPIO Documentation):

from slackclient import SlackClient #GPIO SETUP GPIO.setmode(GPIO.BOARD) GPIO.setwarnings(False) GPIO.setup(8,GPIO.OUT)

And some methods:

def lightOn(): GPIO.output(8, 1) print ("light on!") def lightOff(): GPIO.output(8, 0) print ("light off!")

And then link the methods you've created to the bot's matching text part.

if re.match(r'.*(light off).*', message_text, re.IGNORECASE): //words you want your bot to recognize lightOff() //the gpio method to execute slack_client.api_call( "chat.postMessage", channel=message['channel'], text="Light off!", //bot response as_user=True)

Now, run it!

python3 slackbot_iot.py

Physical gpio setup example

This is an example configuration, of how you can use the GPIO pins to turn on a Led.

I'm using a Raspberry Pi B+ model 1 and the GPIO pins 6(Ground) and 8(GPIO). All the pins of this Raspberry that i'm using can be found in this picture:
