[SOLVED] Hardware replacement

[maddmax1976 (Max)]

Hello to all.

I have an OpenHabian on a Raspberry B, although the version used is not compatible.

To avoid a block following updates I would like to change the hardware.

I have an ubuntu pc, I would like to install OpenHab them and export the configuration from the Raspberry.

The home automation objects were created a bit through the OpenHab web interface, a bit they were written manually in the configuration scripts.

Is there an easy way to be able to clone Raspberry’s OpenHab on the new Ubuntu?

Thanks so much!

• Platform information:
  • Hardware: Raspberry Pi Model B Rev 2
  • OS: Raspbian GNU/Linux 9 (stretch)
  • openHAB version: openHAB 2.5.1-2 (Release Build)

Common… a little search ahead would have been nice.

There are several topic about your question.

Migrate OpenHab 2 to another Host

Hi, i have an OpenHAB installation running on Ubunutu 18.04 LTSR. No i plan to move the installation to another host. Is there more to do then Backup and Restore? https://docs.openhab.org/installation/linux.html#backup-and-restore I user the following Bindings: Homematic Astro Philips Hue Cloud Connector Telegram And i configured some rules… I ask myself for example if i have to reconnect Philips Hue or Cloud Connector. Thx in advance.

Transfer configuration to new Openhabian installation

I’am currently running an older version of the OpenHabian image and would like to upgrade to the newest version. I’ve already setup the new image on a separate sd card and transfered the following folders: /etc/openhab2 /usr/share/openhab2/addons /var/lib/openhab2/habmin /var/lib/openhab2/jsondb /var/lib/openhab2/persistence /var/lib/openhab2/zwave After that I set the correct file owners and rights and started OpenHab2. Openhab boots and seams to work, but there are several problems I do…

Backing/Restoring up openHAB2.x

Note: The information in this post is old, as of version 2.2.0 (and it’s snapshots) openHAB is now distributed with backup and restore scripts! See here for more details. openHAB 2.x currently has two different ways of setting up things: Either through textual configuration or through the user interface which saves to a “jsonDB” database. If you’re looking to backup openHAB then you should look to backing up both the textual configuration files and the database folders. Locations I will be ta…

Thanks for your help.
So do items created through the web interface also create script files?
Do I need only one backup / restore to get two openHabs that work identically? Do I also need to generate a new key for cloud services?

In one of the reported treads it seems that a user has failed with this procedure, however the scenario is different, on which he passes from an old versioen to a new one.

If I have time this weekend I try, I hope everything works at first glance!

[BrutalBirdie (Elias)]

So do items created through the web interface also create script files?

What?
Items, Things, Chanel links etc created via PaperUI are stored in openhab_userdata/jsondb/
What scripts are you referring to? Could you maybe try to describe what you are looking for?

Do I need only one backup / restore to get two openHabs that work identically?

Theoretically, yes.
Be aware that change of IP might cause a slight inconvenience.
See first linked topic, comment.

Migrate OpenHab 2 to another Host

I had openhabian on a RPI2 and moved everything over to a RPI3 using the backup and restore guide with two issues. Issue one was caused by me when I set the IP on the new RPI3 to match the old RPI2. This was solved by fixing the MAC address in router. Issue two was the FireMotD did not install. Fixed using openhabian@openHABianPi:/opt/FireMotD$ sudo ./FireMotD -I -v Your setup may be slightly different if not using openhabian but should work fine.

Do I also need to generate a new key for cloud services?

I am not 100% sure about that one since I don’t use the cloud service. But since it’s restored backup I don’t think a new generated key is necessary.

Do I also need to generate a new key for cloud services?

I believe the system does this automatically. You likely will need to enter the new (secret & PID?) in myopenhab.

jsondb

hi, by script I mean all configuration files like: .items .things .sitemap etc.
I didn’t know that PaperUI wrote in jsondb, I will try to understand the syntax.

Thanks again!

Okay, I’ll let you know after the replacement, thanks

Hi everyone, I have done, i have changed the poor raspberry pi b with a powerful barebones pc.
The OH2’s backup/restore procedure works fine, it’s fast, simply and there is a good documentation on internet.

the only problems i encountered on python scripts.
These scheduled script read the Google Calendar and the Geolocalization of our mobile phones.

at first I was unable to start the scripts due to problems with permissions on the files, then the environment requirements were missing in my pc.

when installing the mosquitto client I was wrong and I installed the server.

Logically, the new mqtt broker conflicted with the one integrated in OH2.

In the end I still managed to make everything work (I hope, since at this moment my ubuntu is upgrading the version).

the only thing I haven’t been able to do is make OH2 make sounds.
From the speaker connected to the headphones, or from the HDMI audio output, I hear the sounds of Ubuntu system, I can play audio files and I hear youtube videos, but no sound comes from OH2.

I did some tests from the console trying to play audio or TextToSpeak but I don’t hear anything I have errors.

Do you have any idea what it could be? I thought that OH2 is probably using an audio subsystem that is not working or not installed on the system, but in PaperUI the only audio setting is set to “use system speaker”.

Thanks bye!

true, sorry! I do it right away

N.B. the problem was still dependent on the change of hardware, so I think it appropriate to complete the discussion with this note for those who are browsing this forum in search of solutions.

I believe that backup / restore scripts do not carry system dependencies but only configuration scripts.

I had to install the libttspico-utils package to give the system the ability to use TTS.

Thanks bye!

That makes sense since Java is cross platform.
