Razberry bricked?

[z-wavettaja]

Hi,

I changed raspberry casing and in that process removed razberry board. Also once in mistake powered raspberry without board attached back.
Then I powered back off, attached board back and started again. But now z-way not working anymore. I don't have any devices visible and then I found from logs that communication with razberry fails.

1. I took a look of hardware troubheshoot steps on https://z-wave.me/support/hardware-problems/
It seems that when powering pi, one led on razberry board goes on for one second.
But z-wave is not able to communicate with board, symptoms are just like descriped and ends to:
"Can not start Z-Wave binding: Error: Bad data – communication failed"

Unpowering does not help.

2. Then I found (https://forum.z-wave.me/viewtopic.php?t=23019) How to test Razberry:
killall z-way-server
cat < /dev/ttyAMA0 &
echo -en "\x01\x03\x00\x15\xe9" > /dev/ttyAMA0

and after that echo command I'm getting no any response (no failure or no answer, nothing).

I think I have this model (https://z-wave.me/products/razberry/razberry-revisions/):
Z-Wave Plus
5th gen chip
ZM5202

Does this mean, that board is now broken or is there something I could still try?

Please present the log. Have you changed just th casing?

Hae you experienced static electroicity spikes?

Log tail below. I did not notice static electricity spikes, but was not grounded while work
I have other same model razberry board at the moment. Also one other raspberry pi 4 free and could move using that.
If this razberry is now really gone, I have understood that I have to pair every device again with other board.

But in that case is it so that I loose also all my z-wave apps/configurations also and have to start all from scratch? Or can I somehow use backup/old files from other board when pairing devices to other board?

You can use a backup to restore in the new board

Managed to restore whole system from backup to new raspi and other razberry board and system is working. I was amazed that also restore network topology without pairing devices worked. Good job!
