Raspberry Pi IoT connect CloudMQTT

Raspberry Pi IoT connect CloudMQTT

In Last Article we have made raspberry pi with dht sensor and OLED display. So, in this blog we will use that hardware to connect CloudMQTT.com for IoT application.

What is MQTT?

MQTT (aka MQ Telemetry Transport) is a machine-to-machine or “Internet of Things” connectivity protocol on top of TCP/IP. It allows extremely lightweight publish/subscribe messaging transport.


Broker , Publisher , Subscriber

CloudMQTT are managed Mosquitto servers in the cloud. Mosquitto implements the MQ Telemetry Transport protocol, MQTT, which provides lightweight methods of carrying out messaging using a publish/subscribe message queueing model.
So , you must sign up CloudMQTT

Raspberry Pi Smart Home Automation with Home Assistant



Raspberry Pi Smart Home Automation with Home Assistant

In the last article we know about OpenHAB Raspberry Pi Open Source smart home. In this blog we will know about Home Assistant Open Source smart home.


What is Home Assistant?

Home Assistant is Open Source Software for smart home or home automation systems.

Home Assistant is an open-source home automation platform running on Python 3.
Track and control all devices at home and automate control.

Home Assistant can install on many platforms such as Windows, Linux ,Mac OSX and embedded platforms such as Raspberry Pi , BeagleBone Black , UDOO , Cubietruck  so you can install in to Raspberry Pi. ( Raspberry pi is popular and low cost then we us Raspberry pi3 board)

Current Version: 0.33.4
Released: November 23, 2016

System Diagram



Hardware

You will need :
Raspberry Pi3 Board
SD card (8GB or more) we use 16 GB
Power supply
Ethernet or WiFi Connection


Software

Raspberry Pi OS
Raspbian Jessie – at the time of writing I have used version Sep 2016 which can be download from here – Raspbian Jessie

RASPBIAN JESSIE WITH PIXEL
Image with PIXEL desktop based on Debian Jessie
Version:September 2016
Release date:2016-09-23
Kernel version:4.4

Raspberry Pi Tools
For Windows User
PuTTY is SSH tools for Remote Command line. Download  moreinfo
WinSCP for remote edit and transfer files. Download  moreinfo

for Linux or MAC os
use terminal for remote command line. ( without installing additional software )
fugu ssh or Filezilla

How to Install Home Assistant on Raspberry Pi

There’s three options to install Home Assistant on a Raspberry Pi.

Manual installation. 
Following this guide doing each step manually. This is highly recommended as a first installation since you get a good overview of the installation.

Hassbian image. 
Basic installation with the same settings as following the manual installation guide. Some additional software is preinstalled to make installation quicker and easier. Installation uses homeassistant user.

All-in-One Installer. 
Fabric based installation script that installs and compiles many of the things an advanced Home Assistant install is likely to need. Installation uses hass user.


We use All-In-One Installer method to install.
Because there is including support for MQTT with websockets, Z-Wave, and the Open-Zwave Control Panel.

The only requirement is that you have a Raspberry Pi with a fresh installation of Raspbian Jessie connected to your network.

Run the following command

$ wget -Nnv https://raw.githubusercontent.com/home-assistant/fabric-home-assistant/master/hass_rpi_installer.sh && bash hass_rpi_installer.sh

Raspberry Pi Smart Home with OpenHAB2


Raspberry Pi Smart Home with OpenHAB2

What is OpenHAB?

OpenHAB is Open Source Software for smart home or home automation systems.

Now Version is openHAB 2. ( Oct 2016 )

OpenHAB 2 is based on the Eclipse SmartHome framework and is fully written in Java.
OpenHAB can install on many platforms such as Windows, Linux ,Mac OSX and embedded platforms such as Raspberry Pi , BeagleBone Black , UDOO , Cubietruck  so you can install in to Raspberry Pi. ( Raspberry pi is popular and low cost )

Raspberry Pi Board 
SD card (8GB or more)
Power supply  
Ethernet or WiFi Connection

Software

Raspberry Pi OS
Raspbian Jessie at the time of writing I have used version Sep 2016 which can be download from here  Raspbian Jessie

How to Install OpenHAB2

1.Update your Raspberry Pi first

sudo apt-get update
sudo apt-get upgrade


2.Install MQTT ( mosquitto ) on Raspberry Pi


First get the repository package signing key, import it into apt, and remove the key file after adding,
sudo wget http://repo.mosquitto.org/debian/mosquitto-repo.gpg.key
sudo apt-key add mosquitto-repo.gpg.key
sudo rm mosquitto-repo.gpg.key



Then make the mosquitto repository available to apt:
cd /etc/apt/sources.list.d/
sudo wget http://repo.mosquitto.org/debian/mosquitto-jessie.list

sudo apt-get update





Now we can install the core packages (server & clients):

sudo apt-get install mosquitto mosquitto-clients



3.Package Repository Installation


Now is Beta Release
Add the openHAB 2 Beta repository to your systems apt sources list (will overwrite your existing openhab2.list):
echo 'deb http://dl.bintray.com/openhab/apt-repo2 testing main' | sudo tee /etc/apt/sources.list.d/openhab2.list

Additionally, you need to add the openHAB 2 Bintray repository key to your package manager:
wget -qO - 'https://bintray.com/user/downloadSubjectPublicKey?username=openhab' | sudo apt-key add -

sudo apt-get update


4.Install add-ons

The offline distribution is full blown and comes with all add-ons


sudo apt-get install openhab2-offline



158 MB. take a time. Relax !


It take 1h 5min 2s ( Thailand only )



5.Start System Service

Start openHAB and register it to be automatically executed at system startup.

sudo systemctl start openhab2.service
sudo systemctl status openhab2.service

sudo systemctl daemon-reload
sudo systemctl enable openhab2.service




Open Web browser goto http://your raspberry pi ip address:8080



Now Install already. 
Then your must config some file for set your smart home automation system.


see next article... How to config file.
