Since this morning, my Zway system suddenly doesn't work anymore.

I'm getting these messages:
[zway] Job 0x07 (Get controller info and supported function classes): No ACK received before timeout
[core] Error: Bad data - communication failed
[core] Tried 5 times without success. Stopping tries.
[core] Notification: critical (z-wave): Cannot start Z-Wave binding: Error: Bad data - communication failed

I have searched the forum but have not found anything that would have helped me.

Also an upgrade to zway 4.0.2 and reboot didn't help.

Any ideas?

Some more info to the problem:

after 23:00 last day, the log was flooded with the messages:
[2023-02-21 23:02:08.777] [zway] Adding job: Get background noise level

After restart of z-way-server no ZWayVDev_zway_ device was created, instead the messages were printed:

I have reinstalled my old Razberry board. Z-Way now seems to work properly again.

If nobody knows better, I will say that the board is defective. I will send it back under warranty.

The new Razberry7 Pro board worked perfectly for only 6 weeks.

Is RaZ 2 working in the same place RaZ 7 is not ? Looks like a hardware fault. We can replace it for you once they are back in stock.

Yes, Raz7 was put on the same Raspberry on the same place as the Raz2.

That's great if you would replace it.

Any idea when that would be? The Pro variant that is.

Hopefully in March

Still waiting for the delivery. Sorry, hope in April
