Google Assistant (via DialogFlow) -> Cloud Function -> MQTT bridge

Based on https://github.com/harperreed/node-ifttt-mqtt-bridge

Fullfillment for DialogFlow intent, breaks down the entites to topic and message and sends to the MQTT broker.

Getting started

• Create a project at Firebase.com
• firebase init

Configure firebase

Install Firebase tools:

$ npm install -g firebase-tools

Instantiate your project:

$ firebase init functions

Don't overwrite existing package.json and index.js

App/MQTT Configuration

You will have to configure a handful of firebase config vars.

• firebase functions:config:set mqtt.server.port=12345
• firebase functions:config:set mqtt.server.host=mqtt://mxx.cloudmqtt.com
• firebase functions:config:set mqtt.server.user=username
• firebase functions:config:set mqtt.server.password=password
• firebase functions:config:set access.api_key=secretapikey

You should generate a unique access.api_key, which will be used later to execute the function.

Deploy

After you configure your vars, you can then deploy:

$ firebase deploy

Usage

Once you deploy you will get a URL: https://us-central1-mqtttest.cloudfunctions.net/post

You can use this url to send a topic and payload to the MQTT:

curl https://us-central1-mqtttest.cloudfunctions.net/post -d "topic=goodnight" -d "message=on" -d "key=apikey"

response:

payload posted sent!

You can send any topic or payload you want.

For instance:

curl https://us-central1-mqtttest.cloudfunctions.net/post -d "topic=goodnight" -d "message=on" -d "key=apikey"
