openHABian in international airspace
The v1.2 release changes and adds a few details in openHABian for a more intuitive experience for beginners and with new hardware, including devices connected by Wifi. The most important change with this release is the addition of a Raspbian Lite based image.

Raspberry Pi Zero W
A few days back the Raspberry Pi Zero W (Pi0W) was released. The Pi0 is a cheaper and smaller Raspberry Pi with only a few external connectors and only one 1GHz core. The latter, especially the lack of a network port, made the Pi0 uninteresting as a “hassle-free” SBC for openHABian. The Pi0 W changes that because of it’s integrated Wifi/Blueooth module.
openHABian v1.2 brings full support for the Pi0W in unattended/headless mode. Read about Wifi setup below.
The Raspberry Pi Zero W is powerful enough to run openHAB and to control your small and mid-sized home / home automation system. It is also a great device as a slave system, e.g. only interacting with your heating system or the garage devices. If you can live with the limited count of connectors and the main uplink via Wifi, the cheap RPi0W might be a good choice for your openHAB(ian) installation.
Raspbian Lite base
If you payed close attention, you know that openHABian for the Raspberry Pi started as a project based on raspbian-ua-netinst, a minimal unattended network installer, perfect for what openHABian was aiming for. You will however also remember, that this rather special system had some restrictions and quirks. A “hassle-free” system should be as predictable as possible, however the differences to a standard Raspbian system confused some openHABian users. Another problem was the need for the support of a Wifi connection with the Pi0W.
With openHABian v1.2 we are introducing a Raspbian Lite based image in parallel to the raspbian-ua-netinst based image. The Raspbian image will take longer to flash but will overall be quicker to configure the system and start openHAB. Additionally it allows for a setup purely via Wifi and therefore is the only option for the RPi0W. As it is based on Raspbian as we know it, I expect this system to create less problems with GPIO or other issues known from the old base. The raspbian-ua-netinst based image is still fully supported and if you were happy with it so far, don’t hesitate to stick with it.
If you own a RPi3, RPi0W or a Pine A64, you can setup and use openHABian v1.2 purely via Wifi. You’ll need to make your SSID and password known to the system before the first boot in just a few steps:
- Flash the system image to your micro SD card
- Access the first partition from your file explorer
- You’ll find the file
openhabian.conf, open it in a text editor
- Uncomment and fill in
- Save, Unmount, Insert, Boot, Enjoy.
The openHABian setup was always quite reliable. Still there were exceptions of cause. In these cases the current state of the installation and a possible error and its solution were not always easy to identify for a new user (at least not without further knowledge of the system).
With v1.2 we’ve added a tiny but useful little addition. The configuration and setup process takes between 5 and 60 minutes (based on device, connection type and bandwidth). During that time you can log in via ssh and will be presented with the configuration progress log, washing away all unclarity.
openHABian promotes a hassle-free system you can use instantly without further modification. There were however three topics not yet covered by openHABian as good as expected by some users: Hostname, Locale and Timezone.
Version 1.2 finally brings openhabian-config menu entries to change the system’s hostname, to adjust the timezone and to change the system language, if
en_US.UTF-8 is not what you are satisfied with. Besides these menu entries the local time zone will now automatically be detected based on your IP, making a manual change mostly obsolete. With these additions
raspi-config is now finally abandoned from the Raspberry Pi openHABian system.
This change and the one before was inspired by @uwe_mutz
As always: If you are on a previous openHABian release, you just have to execute
sudo openhabian-config followed by the “Update” menu entry to gain access to all the latest changes. Please report all problems you encounter.
