I would like to have a strategy in case my Z-Wave controller is broken and I need to install a new one.
How could such a strategy, such a way to backup my Z-Wave network and get it running again on a new (maybe different) controller look like?
Z-Wave Controller: Aeotec AEOEZW090-C Gen5
About 15 Nodes (also battery devices)
This is very important for me, as I now control some important parts of my house via OH and Z-Wave, and in the event of a controller failure, it should be possible to replace it quickly (without having to remove hard-wired nodes).
You need to backup your controller and need to use the vendor specific software to exist for that purpose. For the Aeotec stick it’s AFAIK a Windows software that you can download from their website.
I also have the Aeotec Z-Stick Gen5. You can use the backup software for this stick which you can find here. As fas as I know it is only availbale for Windows.
The backup file can then be reloaded to antoher stick which will make a clone of the first one. So I have another Z-Stick as spare part which can be used in the case of a failure. Of course, you need to save backups periodically and this means to stop using the Stick with OH and make a backup (about 5 minutes time).
During that time it would be wise to make an openHAB backup too. If you have secure devices the key is in the openHAB backup.
Thanks for the hint, I make a backup every day using a cronjob (export influxdb, ‘openhab2-backup’, copy important files to a nas, …)
On this occasion, I read about the “Zensys Z-Wave Tools” and tried them for a short time. If someone has more experience with them, is it possible to transfer the Z-Wave configuration to another Z-Wave controller (different hardware)?
