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.
