I managed to also do this with sernet and socat by doing this:

zwave stick → pi → socat → network → 2nd pi → ser2net → serial device

Also works with a Vera

Put this in cron and run it every few minutes to keep socat connection up

check_socat_zwave.sh

#!/bin/bash
LOCALPORT=/dev/zwave
REMOTEPORT=10.11.12.222:7676
TIMEWAIT=10

echo "checking socat..."
if [[ $(ps ax | grep -v grep | grep tcp:$REMOTEPORT | wc -l) -eq 0 ]]
then
  echo "  ... restarting"
  /usr/bin/socat pty,link=$LOCALPORT,raw,group=root,mode=777 tcp:$REMOTEPORT &

And settings for ser2net (in /etc/ser2net.conf)
7676:raw:0:/dev/ttyS):115200 8DATABITS NONE 1STOPBIT

Last piece I need is how to detect ping zwave chip from home assistant and restart it when connection is broken.
