Using socat or tcp port on Virtualbox VM

I come from Openhab and I used Nuke Vera as per (Using a Vera Edge as a network-attached zwave device (skipping the vera software)) to get my Z-wave devices into Openhab.

Now I am running Home Assistant using the official VirtualBox VM. I can’t see to get the TCP serial port into Home Assistant.

Things I’ve tried:
Virtualbox port: I am using socat to create a device on my Mac machine /dev/zwavevera. I tried creating a port in virtualbox setup using “host device”. It seemed to connect but drops quite quickly, and Virtualbox says I need to suspend and restart the VM to get it going.

Socat in HASS: I installed ssh addon, ran apk add socat. But if I try connect, I get an error of “Read only filesystem.”

Is there anyway to connect a Serial over IP port on the Home Assistant OS?

Use the Z-Wave JS UI add-on and specify your device path in the Z-Wave settings as tcp://.... Socat not needed.

Thanks. So would I need to install that separately, and then add the add-on? Or does it work natively in Home assistant?

Your linked topic says that ser2net is running on the Vera. You simply configure Z-Wave JS UI to talk to the serial port with the tcp address. Instead of a usb path in the settings, use tcp://<vera IP>:<vera port>.

Thanks, that works.
