Start over on new Raspberry PI

Post by vinisz »

Hi,

Would like to start with a "clean" installation on another raspberry PI, only keeping all the zwave devices and config.
Is there any guide available on how to backup/migrate/start-over ?
I have no rules or automation to backup, that is all in node-red.

z-wave devices are stored on controller. If you re-install software without resetting of controller, you should have all devices after fresh start. You need got through every device and click on [Call for NIFG] Button on status page in expert mode.

So did I newly as I migrated from Openhab to Z-Way. I just bought and prepared a new sd card with fresh debian installation. Then just installed zway and restarted raspberry pi. After start I saw all devices, but without interview.

The only exception is security - if you delete all files on the Pi, you will loose the security key. So keep your backup files made in Z-Way. If your installation is not secure, you can easily restore everything just based on the Z-Wave chip info

What files are needed to move the security key(s) over?

I think the network key might be stored as "networkKey" in this file:

Code: Select all

/opt/z-way-server/config/zddx/YOURHOMEID-DevicesData.xml

You can see YOURHOMEID at http://IP:8083/expert/#/network/controller

It would be nice to get a confirmation on this, and also if other keys in this file are crucial for a migration.

Sometimes things go wrong and you want to start over. Sometimes you might want a fresh start just to be sure. It is easy to reset or “wipe” a Raspberry Pi. You might think of it as a “factory reset”.

If you are using NOOBS you can hold the [SHIFT] key while rebooting to launch the NOOBS recovery system. This lets you restore everything to “factory default”. People have reported this not working with a wireless keyboard.

Here are two easy, obvious options:

NOOBS recovery system ( see above )
Reflash the SD Card
WARNING - Make sure you back everything up before wiping your system.

Where is the spam filter here ?
Leonard posts 1 blank message. and its allowed from mr Wank off.

New users need to be blocked, until first post is allowed by admin.
That is standard now in most forums.

We try to keep some ballance between spam-free forum and good user experience. Currently we went down to ~1 span message per day which is acceptable for us to remove manually.

Do you believe Leonard is a spam too? Now even organic intelegence is puzzled ;)
