Darell Tan 1fbc4d520a Use a more secure PIN config by default
The server used to use the hap default PIN, but using a fixed PIN is not
secure. A random PIN is now generated on first run and displayed to the
console (or journal), similar to how homebridge does it. It can also be
specified explicitly by the user in the config file.

hap-z2m Bridge
===============
A HomeKit <-> Zigbee2MQTT bridge written in Go, so I don't have to install more NodeJS rubbish.
It is essentially a Homebridge + homebride-z2m replacement.
It compiles down to a <10 MB static binary instead of another 200++ MB Docker container.
It uses the [hap library](https://github.com/brutella/hap) for interfacing with HomeKit.
It is quite barebones, so there is no configuration for the bridge, apart from the MQTT server & credentials.
The bridge configures and exposes devices based on z2m's MQTT messages.
Currently only supports the types of Zigbee devices I have:
- Climate sensors (temp, humidity)
- Contact sensors
- Motion sensors
- Wall switch
- Dimmer, or dimmable light bulbs
If you do use this software, note that it's in development and may contains bugs,
or may even burn your house down. I offer no warranty, but you are welcome to file bugs.
Building
=========
To compile `hap-z2m`, use:
go build -v -trimpath -ldflags="-s -w" ./cmd/...
Configuration
==============
The MQTT broker that Zigbee2MQTT connects to is specified using the following:
- Server
- Username
- Password
Additionally, these options control networking aspects for the bridge:
- `ListenAddr` can be used to bind to a specific port and/or address,
useful for selecting a fixed port for firewall rules.
- `Interfaces` limit which interfaces mDNS broadcasts appear on,
and which addresses to use when broadcasting.
These settings are optional and can be left blank.
The pairing code for the server is generated dynamically on first startup
and printed to the console (or systemd journal). Alternatively, you can specify
it using `Pin` in the config file to have it fixed.
