NEED HELP! Zwave problems after new domoticz version, how to backup?

[SpawnMC]

Hi, I need your help. I have now used two ajhre without problems my raspberry with openzwave USB. since the new version of domoticz was installed, domoticz crashes after about 15 minutes.

That's why I put a new system on a new memory card. raspberry with STRETCH and domoticz 4.97.
I still have the old configuration.

I did a backup with domoticz and made the configuration of the openzave hardware.

after I load the backup in domoticz, I have all the switches, etc.
also the devices are restored
but under the hardware / openzwave usb I have no nodes.

how can i restore my system?

Thank you for your help, I am desperate for 3 days work ...

I think your USB port is not correct, you have two times openzwave ? One with ttyAMA0 (that can not be right i think) and 1 on ttyUSB20
First, give them each a different name !! (never give something the same name!?)
- go to the devices tab, search for a switch you had, check the hardware it was used on (lets say OpenZWave_1)
- now make sure in the hardware overview, the other openzwave hardware is disabled, that is the wrong one,
- configure/enable the correct one, make sure the USB port is correct!!
- Now check the log

Another thing, "the new version" ,.. there are new versions everyday!, What was your old version, what is your current version ?
