dialogflow-ifttt-webhooks-smartlight-chatbot

Build a chatbot using Dialogflow, Webhooks, and IFTTT to control your smart light bulb. For this project, I'll be integrating it with telegram.

1. Dialogflow

1.1 Go to https://dialogflow.cloud.google.com/ and sign in using your Google account

1.2 Create an Agent (chatbot)

Go to the dropdown menu on the top-lefthand corner and select "Create new agent"

1.3 Create an Intent

  • We'll be needing 3 intents for this project

  1. Click "CREATE INTENT" and change the title to "lights"
  • Training Phrases : "/lights"

  • Responses: Click on "+" and select Telegram.
  • "ADD RESPONSES", select "Quick Replies"
  • Quick replies title: "On/Off lights?"
  • Button titles: "On", "Off"

  • Save and go back to Intents page
  1. Hover over the "lights" intent and select "Add follow-up intent"
  • Ensure that you add "lights-followup" as the input and output context

  • Change the title to "lights - on"
  • Training Phrases: "On"
  • Quick replies title: "Switching on the lights..."
  • Button titles: "Off"

  • Fulfillment: "Enable webhook call for this intent"

  • Repeat the steps for "lights - off"
  1. Telegram Integrations
  • Go to Integrations page
  • Enable Telegram; Get a Telegram access token from BotFather and insert it in the ‘Telegram Token’ field.
  • You should be able to start your Telegram bot

2. IFTTT applet

1.1 Sign in to https://ifttt.com/

1.2 Create an applet to switch on the lights. You should see "If + This Then That"

  • click on the "+" and select "Webhooks" as the service. Select "Receive a web request".
  • Event Name: "lights_on"
  • click on the "+" and select "Yeelight" (or other supported brands) as the action. Select "Toggle lights on/off". Select your light's name and choose "On".

1.3 Repeat the steps for "lights_off"

1.4 You will notice that there are other options for your light settings. You can explore them on your own!

3. Heroku (Webhook service)

1.1 Create a Heroku account

1.2 Browse to https://heroku.com/deploy?template=https://github.com/jpruden92/ifttt-dialogflow-webhook

1.3 Enter an app name and choose a region. Then click on "Deploy app".

1.4 Click on "View" and you should see the URL of your fulfillment: https://<app_name>.herokuapp.com/fulfillment

  • Copy the Fulfillment URL and paste it under Dialogflow's Fulfillment > Webhook > URL*
  • Basic Auth(Default): Username and password is "test"

1.5 IFTTT Events URL: Browse to https://ifttt.com/maker_webhooks/settings and copy the URL
