HA compatible Z-wave controller? (sopuli.xyz)

Hello all,

I've been fighting with razberry7 pro on top of rpi4B and it just doesn't work reliably (if at all). I've dug around the internet, tried different software on it, verified that firmware is up to date and so on and even fed my logs to LLMs in hopes they could spot something. Currently my z-wave devices are practically useless (gladly I got devices with physical controls too) and based on discussions around I'm not alone.

So, I think it's time for me to just get something better. Ideal device would be wired over ethernet and have z-wave and zigbee hubs and possibly POE, but I haven't found any which would also be fully supported by HA.

ZWA-2 should be pretty solid choise, but I'm running HAOS in a virtual machine on my proxmox host and I'd really like to have an option to migrate VM to different hardware as needed but that would require also physically moving the USB plug from one host to another.

What are your experiences, what I should get? I'm in EU, so frequencies need to match, but otherwise I'm pretty open for suggestions and having a rock solid z-wave network is a top priority. If it means using ZWA-2 or some other USB gadget I can work with it, but, again, ideally I'd like to have something wired to the network. Wifi is of course an option, but good old ethernet would be preferred.

I migrated from another ZwaveMe product to the ZWA-2 (which was a firmware related headache to get my network out of the ZwaveMe one onto it but fortunately finally got it resolved) on a QEMU machine under Incus with no problems but I understand the desire, and the ZWA-2 has been rock solid.

Have you seen this (experimental) project

I've not dug into it much other than being aware of it, but conceptually don't see why it, or potentially one also leveraging a ZBT-1 or -2 couldn't also be possible, if you're prepared to tinker.

I saw that project and it seems to be pretty promising, but as it's on pretty experimental state I think I'll skip that for now. The biggest headache I've had with home automation so far is unstable z-wave connectivity, so I'm not really interested on tinkering with experimental stuff.

But good to hear that ZWA-2 actually works as well as advertising claims.
