openHAB is one in every of the foremost notable and oldest names in Home Automation. OpenHAB was created in 2010 by Kai Kreuzer, developed in Java and based mostly totally on Eclipse’s SmartHome framework.
To install openHAB on android Box TV, you would like to use the acceptable version of Armbian Ubuntu. as a result of running on Java, Java should be put in before putting in openHAB.
Note: the examples in this article are done with the configuration for the mini TX3. You need to change a few places in this guide to suit the device you are using
Prepare
Hardware
Prepare the following:
- An Android box tv using ARM chips supported by Armbian
- A USB or microSD memory card with a capacity of 8GB or more
- A RJ45 cable to connect Android Box to the wifi router
Software
- SD Memory Card Formatter is used to format the USB or memory card stably to avoid damaging the device.
- balenaEtcher is used to flash Armbian onto USB or memory card.
- The latest Armbian Ubuntu bionic is suitable for the chip in use.
- Advanced IP Scanner to scan IP devices in LAN, find openHAB IP server.
- PuTTY to access SSH into Android box
- WinSCP to browse openHAB files via SFTP without having to install add-ons like FTP or Samba share to save system resources
Flash Armbian onto memory card
- Once you’ve chosen the correct version of Armbian Ubuntu bionic above and downloaded successfully, you extract a file with a .img extension of about 1.3GB.
- Next format the USB or memory card with SD Memory Card Formatter software to ensure the USB or memory card is in the best condition.
- Open balenaEtcher, select the extracted .img file above to proceed to flash on USB or memory card.
- when balenaEtcher reports finished Flash, remove the USB stick or memory card from the USB port and then reinsert the computer to the BOOT partition on the USB flash drive.
- Access BOOT partition, find the file uEnv.ini, correct dtb_name with the device you are using.
dtb_name=/dtb/meson-gxl-s905w-tx3-mini.dtb
- In the BOOT partition, look for the extlinux directory, find the extlinux.conf file and correct the dtb in that file to match the device you are using. Remember to remove the “#” before the line
FDT /dtb/meson-gxl-s905w-tx3-mini.dtb
The name dtb_name can be found below
- Eject USB or memory card from the computer
Install Armbian on the Android box
- Plug the Android RJ45 cable into the wifi router
- Insert the USB or memory card into the USB port on the Android box, hold the reset button and power the Android box, after 5 seconds release the reset button to Android Armbian USB boot box or memory card
- Open Advanced IP Scanner to find the IP of the Android box
- Use PuTTY to SSH into Armbian using the newly scanned IP above with port 22
Login default account
user: root password: 1234
When logging in successfully, proceed to change the default password and create an additional account as instructed by Armbian
At this point, you can go straight through the steps of installing Java and openHAB. If not, you can do the lower part to let Armbian boot from eMMC, take advantage of the 16GB NAND drive available in Android box for faster speed, cooler, more stable, without using memory card / usb
Transfer Armbian from the memory card to Android eMMC box
This part may occur risks, resulting in irreparable errors. Therefore you have to think carefully before doing
Back up all available eMMC so that when there’s a problem, come back. Use the “ddbr” command and follow the onscreen instructions to backup
ddbr
When the backup is completed, use WinSCP to make SFTP copy the backup file to your computer and save it
Using the “/root/install.sh” command to run the partition script, copy the OS from the memory card to the NAND. By the time the Complete newspaper is finished
/root/install.sh
Install Java Platform
openHAB runs on Java 8 (openHAB doesn't work on Java 9 and 10, doesn't work on 64bit versions), install Java before installing openHAB
OpenJDK is unstable on ARM devices, so there are only two options: Oracle Java and Zulu. Zulu is a Java SE fully licensed opensource, optimized for devices running ARM chips. Zulu will be the most appropriate and simple option.
To install Zulu Embeded 8, SSH into Armbian with PuTTY and copy the below commands
Copy 1 line at a time. (right click to Paste)
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 0xB1998361219BD9C9
sudo apt-add-repository 'deb http://repos.azulsystems.com/ubuntu stable main'
sudo apt-get update
sudo apt-get install zulu-embedded-8
install zulu embedded 8 successfully, check it again by command
java -version
Install openHAB
Install the latest Milestone version using the following commands
wget -qO - 'https://bintray.com/user/downloadSubjectPublicKey?username=openhab' | sudo apt-key add - sudo apt-get install apt-transport-https echo 'deb https://dl.bintray.com/openhab/apt-repo2 testing main' | sudo tee /etc/apt/sources.list.d/openhab2.list sudo apt-get update && sudo apt-get install openhab2
start openHAB
sudo /bin/systemctl daemon-reload sudo /bin/systemctl enable openhab2.service sudo /bin/systemctl start openhab2.service
Open the web browser and access the address
http://<ip-openhab-server>:8080
Select Standard and wait for openHAB to run some more settings needed to use it
