Not me. I have no experience porting.

I do. Whether it makes sense or not, is a different matter :)

Yes. It works fine, AFAICT. Here's what I did:

- pkg_add node

- added a _zigbee2mqtt user similar to other daemon users

- added this user to the 'dialer' group so that it can access the
calling unit (e.g. /dev/cuaU0). This can (and probably should, TBH)
be avoided by changing the device's owner, either permanently or via
hotplugd, but I didn't bother to.

- copied zigbee2mqtt into (a newly created) /usr/local/opt/zigbee2mqtt.

- change the ownership of /usr/local/opt/zigbee2mqtt/* to _zigbee2mqtt

- created /etc/rc.d/zigbee2mqtt with the following contents:

#!/bin/ksh

daemon="/usr/local/bin/node"
daemon_flags="/usr/local/opt/zigbee2mqtt/index.js"
daemon_user=_zigbee2mqtt

. /etc/rc.d/rc.subr

pexp="$(eval echo ${daemon}${daemon_flags:+ ${daemon_flags}})"
rc_bg=YES
rc_reload=NO

rc_cmd $1

- rcctl enable zigbee2mqtt (* see note below)
- rcctl start zigbee2mqtt

And that's it.

* Note that this suffers from the already described problem with node
ports, in that it won't start automatically on boot, but it will start
manually with "rcctl start".

Have been using it for a while, and am happy with it. Not so happy with
my setup, because it really should be properly installed/ported, but *I*
didn't bother to. E.g. the 'data' directory is a mess, holding the
configuration files (should be in /etc), logs (/var/log), and the state
and database files (I'd put them somewhere in /var).
