zwave to Ethernet bridge (lemmy.ca)

I'm wondering if I can get a device that enables zwave over Ethernet/wifi and connect that to my home assistant setup?

Basically I have a home assistant setup in my house. I want to add a few simple things to my parents place but I want it to all be on the same HA instance.

On the router in my parents place, I can install wireguard to connect it to my LAN. So now my parents network is the same as my LAN network.

I'm looking for a device that can connect to zwave and then send that info over the LAN to my home assistant. Does such a thing exist? Thanks.

If you have a device such as a raspberry pi, you could install zwavetomqtt on there and as long as you can connect that to your mqtt server in home assistant then you can add those devices via mqtt

I would just use a USB dongle, personally

If your parents network and yours become "the same LAN", I guess you just need to connect the same way you'd connect to your app locally. I don't see why a third-party device is needed

I need to connect zwave devices at my parents place but the controller USB dongle is at my place.

If I understand correctly, you have a Home Assistant server, and a Z-Wave USB dongle plugged into the machine the server runs on. I think this can help:

This seems to be exactly what I'm looking for, thanks!

It might be easier to build\find a usb to IP bridge. I know there are some commercial products that do this and a couple open source apps as well. I haven't used either in years though.
