Change the Z-Wave Stick

[Solderbro]

Learned today about the incompatibility of raspi4b and the Aeotech Gen 5 stick. No function at all, not on USB2 nor USB3 port possible.

But found a zwave.me stick in my archives, that possibly could be plugged to the raspi 4. So i can get my raspi 3b+ and the raspi4b running with their own stick at the same time.
Is it possible to move the devices from one Domoticz to the other? Found these node-config transfer menus under hardware.

Not sure if this works for you, but you can try the zwave cloner

What problem are you referring to? I have had a number of aeotec usb services and there was indeed a problem with the power of the stick which would not work after reboot. The newer version works fine for me. I copied the entire old stick to the new one with no issues and kept the old one for backup.

There was 2 solutions for old zstick gen5. Use a hub or a small mod on the stick you may be able to find on the net... I have transfered an old stick conf myself but on a newer one only. So same device old was kept as a backup as thats a spof...

There is a known hardware bug in the USB, i modified my Gen-5 with the new resistor.

Now the raspi 4 is able to see the Aeotec and presents the OCZ id like on the raspi 3B, but there is no communication. On domoticz on the raspi4 the device list is completely empty like after a hard reset. So is rollback everyrthing to the 3B again and the Aeotec is able to present all known devices again.

Aeotec on Raspi 4b no devices

There is some bad failure, the backup function did not handle and transfer the zwave session key. So the stick responds no devices and ignore all actions, this is a huge bummer. If everything must be ditched to the closet i will definitely ditch domoticz and start new with home assistant.

If you're sure of this, as all this in kept in the stick, HA will not do better than Domoticz on this...
Take care to have the same ttyUSB allocated as PI3 on PI4 as it's not enumerated in the same way on your capture: Bad tty setup in Domoticz => No devices seen as well.

It succeeded, did resolder the Gen-5 with the 1.5k Ohms resistor what made the USB working on the raspi 4. But entered a new problem, Domoticz-64 does not handle a backup file from Domoticz-32. The process just blocked and hang up Domoticz at all.

Finally the raspi is on HA now, the Gen-5 offered all 34 devices after using the security key from Domoticz as the S1 key in HA. All entities were recreated in Zwave-JS and i had to rewrite my automations in yaml. I think for informations reason, this should be kept.

1. The Gen-5 stick works with the 1.5 kOhm solder hack on the raspi-4
2. Aeotec stick stored devices can be transfered when transfering the secret key too
