Configuration - openHAB

We move on to the next stage, install and configure the openHAB automation platform.

To run the platform server, you must have java.

$ sudo apt-get install oracle-java8-jdk

First we will load the installation packages.

$ sudo mkdir /opt/openhab
$ cd /opt/openhab
$ sudo wget https://bintray.com/artifact/download/openhab/bin/distribution-1.8.3-runtime.zip
$ sudo wget https://bintray.com/artifact/download/openhab/bin/distribution-1.8.3-addons.zip
$ sudo unzip distribution-1.8.3-runtime.zip 

We add the add-on package to the temporary folder, in order to accelerate the loading of the platform, we will take only the necessary modules.

$ sudo unzip distribution-1.8.3-addons.zip -d addons-distrib
$ sudo rm distribution-1.8.3-*

We copy the modules we need.

$ sudo cp addons-distrib/org.openhab.binding.exec-1.8.3.jar addons/
$ sudo cp addons-distrib/org.openhab.binding.ntp-1.8.3.jar addons/
$ sudo cp addons-distrib/org.openhab.persistence.logging-1.8.3.jar addons/
$ sudo cp addons-distrib/org.openhab.persistence.rrd4j-1.8.3.jar addons/

Create a device configuration file.

$ sudo nano configurations/items/default.items
Group   All
Group   devrm   (All)
DateTime Date "Date [%1$td %1$tb %1$tY]" { ntp="Europe/Moscow:ru_RU" }
Number  devrm_t "RM2-T [%.1f °C]" (devrm)  { exec="<[/opt/broadlink/temp.py:300000:]" }
Switch  devrm_01 (devrm) { exec=">[ON:/opt/broadlink/send.py /opt/broadlink/code/rm1_a] >[OFF:/opt/broadlink/send.py /opt/broadlink/code/rm1_d]" }

Create the UI configuration file.

$ sudo nano configurations/sitemaps/default.sitemap
sitemap default label="My Smart Home" {
 Frame label="Date" {
  Text item=Date icon="calendar"
 }
 Frame label="Broadlink RM Pro" {
  Switch item=devrm_01 label="Switch" icon="switch" mappings=["ON"="On.","OFF"="Off."]
  Text item=devrm_t icon="temperature"
  Image url="http://10.0.1.12:8080/rrdchart.png?items=devrm_t&period=3D"
 }
}

Create a configuration file for the storage system.

$ sudo nano configurations/persistence/rrd4j.persist
Strategies {
        everyMinute     : "0 * * * * ?"
        default = everyChange
}
Items {
        devrm_t : strategy = everyChange, everyMinute, restoreOnStartup
}

Create an openHAB automation platform configuration file.

$ sudo cp configurations/openhab_default.cfg configurations/openhab.cfg 

Configuring and adding openHAB to the system startup.

Create a service start script.

$ sudo nano /etc/init.d/openhab
#!/bin/sh

        echo "Usage: /etc/init.d/$DAEMON_NAME {start|stop|restart|status}"
        exit 1
        ;;

esac
exit 0

Save the script, make it executable and add it to the system's startup.

$ sudo chmod a+x /etc/init.d/openhab 
$ sudo update-rc.d openhab defaults

Now restart the system. After rebooting in the browser, open the address http: //a.b.c.d: 8080, where a.b.c.d is the IP address of Raspberry Pi. If everything is configured correctly, we will see the openHAB user interface that we configured.

Do not forget to install the official openHAB mobile application on your mobile device on Android or iOS.
