Zwave transfer

I have my unraid server in the attic, running a VM home assistant there with an Aotec zwave USB stick. The zwave connection downstairs is sometimes slow, so I have recently installed an Odroid C4 with a second home assistant installation downstairs with a second aotec stick. Which sends some zwave instances via remote home assistant to home assistant 1 on the unraid server.

How can I easily move all zwave devices (18 pcs) from home assistant 1 (Unraid) to home assistant 2 (odroid).

For example, is it also possible to put the aotec zwave stick from the unraid server into the odroid? There are 18 devices on that stick. On the other stick on the odroid there are only a few.

Which Z-wave Add-on are you running on the 2 instances of Home Assistant? If you are using Z-wave-JS UI you can simply add a new instance of the Z-wave integration and configure it to use the WebSocket server of the second Home Assistant instance.

Yes. You can have 2 zwave sticks on a single host.
I am not sure how this works for HAOS since I am not certain if running 2 of same addon is possible. It would be possible that you can connect one stick with zwavejs and the other using zwavejsui but again, not sure for this.

If using docker this is completly possible by running 2 seperate zwavejsui containers, connecting each stick to a container and connecting both to HA using zwave integration.
This is the method you should be using now. Connecting over websocket to remote zwavejs instance.

I am not sure your goal however. Why are you doing this?

It is not, out of the box. There is a thread here on the forum about making a custom add-on copy, but I would consider that a path for “advanced users”.

I use the adddon Z-wave JS.

I want to drop the aotec stick with 2 nodes and reconnect those two devicss to the stick coming from the instance of attic.

And then I hesitate if I want to keep two hassios up and running and maybe drop the whole hassio on the VM on unraid. That remains to be determined. I was very much hoping that I wouldn’t have to include and exclude all the devices and so I understand I don’t have to. I’m going to move the stick and see what happens. Thank you guys so much!

The network goes with the stick

Move the 2 devices to the network(usb stick) with more devices. Then move that stick to the device you prefer

If you have home with 3 floors(including basement) The middle floor may be best location

I have a network running on a RasPi. It’s not full HAOS. Instead it is Ubuntu with docker and zwavejsui container. I connect to HA over ethernet and it works flawless
