openHABian hassle-free openHAB Setup

It works most of the time but the warning is there for a reason. So prepare (and test!) your backups first.

Hi Markus,
I tried last week to install the auto-backup but failed and today it worked properly.
Thanks for that, really nice feature which is easy to use.

I could not find the information how often and what time the backup is running? Now I could search in the sources. But I think this will also be interesting for others, so you might can answer it here.

Thanks
Sebastian

dd semiannually, rsync once a week
See systemctl list-timers, you can change frequency in /etc/systemd/system/sd*.timer
Added this to the docs, too.

Will openHABian 1.6 support USB boot as lately provided by RPi 4 (see https://github.com/raspberrypi/rpi-eeprom/issues/28)?

That would completely solve the SD card wear issues…

No as an application it won’t.
It’s based on latest Raspberry Pi OS though (as of August, 2020) so you can use what’s in there.

It would create a bunch of new problems in the first place.
openHABian is built to save users from these to happen. Use ZRAM to mitigate SD wear issues.

Hi all,
I’ve got Openhab running pretty smooth on an old Raspi.
Just a few scripts running in other words it’s not a very heavy duty system.
Would it be better to upgrade the hardware a bit? I want a system which is solid as a rock, with a good backup functionality. I make backups now with this Raspberry Pi but to be honest, if the system would crash I wouldn’t have a clue where to start :wink:

I was thinking a NUC or something like that would be a wiser piece of hardware instead of this Raspi. Am I right?

No not at all. You would need to manually install everything, losing all the benefits of the openHABian image.
And if it’s running fine on your old box it’ll run as fine when you install openHABian instead, so how could that be wiser in whatever dimension?

All it takes is another SD card. I’d get another RPi, though, and keep the old one as a spare.

Hi,

just one question:
How can I update from openhabian 1.5 to openhabian 1.6?
… or is it not necessary when I have all up to date with

sudo apt full-upgrade

?
Some information of my system:

cat /etc/os-release
PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"
NAME="Raspbian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

 uname -a

Linux homesrv6neu 5.4.51-v7l+ #1333 SMP Mon Aug 10 16:51:40 BST 2020 armv7l GNU/Linux

Thank you in advance

openHABian offers to upgrade itself every time you start openhabian-config.
Strictly speaking, you cannot upgrade to a specific version but only ever to the most recent one.

That’s something different. That command is not upgrading openHABian itself (openHABian is only the scripts) but all installed packages of the underlying OS - incl. openHAB.

So, if the underlying OS is up to date and openhabian-config is on version 1.6-880 it is ok so far and I don’T have to update anything?

yes but remember the setup is still as it was created when you installed it for the first time.
So eventually uninstall/purge and reinstall components that have changed since such as e.g. ZRAM or FIND.

OK, thanks. That’s fine for me. I installed newly on Openhabian 1.5 a few days ago and updated everything to current version. (I took a lot of time)
So I think I don’t have to start from scratch and install everything newly?

Thanks for the tip.
I’ll consider buying a fresh new Rpi and clone the SDcard.

Do NOT clone but install openHABian from scratch and import the config from the old box.

Thanks,
One more question:
What do you think is the best way to start manually a raw copy, e.g. after or before major changes on the system. Best way to start dd service manually or to use the script in the openhabian-config to re-setup everything?

raw copy is not a backup

Only ever use it in addition to a backup. And if you do, your question does not make sense.
You should take backups before AND after major changes.

I do also use a regular backup script and do backups before and after major changes but I also want to make a raw copy after I did major changes and the system is stable. In case I need recovery there is only sd card switch necessary.

So you answered your own question. To answer your second question only ever use the openhabian-config menu option. It does more than just dd, see code.

Ah, now I got it. First sentence was not meant to be a question. :slight_smile:
Just wanted to know if I should use openhabian-config, so thanks for answering.

Hi @mstormi, just want to info that I found raspi-config on welcome screen when logged in using ssh after fresh install


Use raspi-config to set the country before use.
