Step 1: Matrix Core & Matrix HAL Installation on RPi

1. Add the Matrix repository and key.

curl <a href="https://apt.matrix.one/doc/apt-key.gpg"> <a href="https://apt.matrix.one/doc/apt-key.gpg"> https://apt.matrix.one/doc/apt-key.gpg </a> </a> | sudo apt-key add -
echo "deb <a href="https://apt.matrix.one/raspbian"> <a href="https://apt.matrix.one/doc/apt-key.gpg"> https://apt.matrix.one/doc/apt-key.gpg </a> </a> $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/matrixlabs.list

Matrix repository for Matrix HAL

curl <a href="https://apt.matrix.one/doc/apt-key.gpg"> <a href="https://apt.matrix.one/doc/apt-key.gpg"> https://apt.matrix.one/doc/apt-key.gpg </a> </a> | sudo apt-key add -echo "deb <a href="https://apt.matrix.one/raspbian"> <a href="https://apt.matrix.one/doc/apt-key.gpg"> https://apt.matrix.one/doc/apt-key.gpg </a> </a> $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/matrixlabs.list

sudo apt-get update

sudo apt-get upgrade

2. Install the the Matrix Core packages.

sudo apt-get install matrixio-malos

sudo reboot

Install the the MATRIX HAL packages.

sudo apt-get install matrixio-creator-init libmatrixio-creator-hal libmatrixio-creator-hal-dev <br>

Reboot your device.

 sudo reboot

3. To install ZeroMQ

echo "deb <a href="http://download.opensuse.org/repositories/network:/messaging:/zeromq:/release-stable/Debian_9.0/"> http://download.opensuse.org/repositories/network...</a> ./" | sudo tee /etc/apt/sources.list.d/zeromq.list

wget <a href="https://download.opensuse.org/repositories/network:/messaging:/zeromq:/release-stable/Debian_9.0/Release.key"> https://download.opensuse.org/repositories/networ...</a> -O- | sudo apt-key add

4. JavaScript setup
Create a node project folder in the home directory of RPi

cd ~/<br>mkdir js-matrix-core-app (whatever name you want)

cd js-matrix-core-app

 npm init

5. Installing npm Packages for ZMQ and Protocol Buffers

To install the ZMQ and MATRIX Protocol Buffers npm packages. Make sure you are in directory which you created above (name you give). Here I gave it js-matrix-core-app. This allows you to interact with Matrix Core through Node.js.

npm install zeromq --save

npm install matrix-protos --save<br>

As I am using JavaScript, so to use PWM for external LEDs I am using Matrix lite library. To install it use command shown below make sure you are in same directory which we created while installing Matrix core.

npm install @matrix-io/matrix-lite --save

Step 2: Snips App (update)

1. Create a new slots and give it name whatever you want. Here I am using four slots

switch for on, off, open, and close state
room for different rooms such as bedroom, bathroom etc
device for devices such as light, fan, door etc
brightness for setting brightness of light in different rooms.

2. Then give slot type name. Here I am building custom slot type.

room slot

Give any name whatever you want. After that add slot values "bathroom", "bedroom", "kitchen", and "main hall" etc.

For switch slot Give any name whatever you want.

After that add slot values "on", "off", "open", and "close".

Device slot

Give any name whatever you want. After that add slot values "light", "fan", and "door".

brightness slot

Give any name whatever you want. After that add slot values 75, 50, 25, 0

3. Close the app, in order to tell the training example which slot is used

Double click on Off and On and select slot name(switch).
Double click on room name and select slot name(room).
Double click on light, fan and select slot name(device).
Double click on values(0, 25, 50) and select slot name(brightness).

Then save it and you can test it in window provided right hand side of the page.

4. Then deploy it

Step 3: Required Npm Package

For sending mail install node package

npm install nodemailer

Npm package for bidirectional event-based communication

 npm install socket.io

Npm package for express

npm install express

If you want to hear the words. You can download this node package.

 npm install say

Add these lines in program (example)

 const say = require('say')

 say.speak('Brightness is set to 75');

Step 4: Webpage

I made a page for showing the logs (room, devices, device state, intensity value and date) and gauge showing current intensity value so that I can know which command I used while talking to the snips. Follow the steps giving below for making a webpage.

Note - You can use either Node server or Apache server.

In this project I am using node server as Apache server is slow and it was not able to update data correctly.

Note - If you use code given in this project make sure your all the data is in cd /var/www/html directory or you can change location in the program.

First, to install Apache server using command (Not required)

sudo apt-get install apache2

Apache server is not required if you have node server or Node server Make an empty file name server.js, add program given in program step and save it.

To run server use command
