It looks like Go has adopted 15s TCP keepalives as a default for _all_ TCP connections, which is quite dumb if you ask me. https://github.com/golang/go/issues/48622 For the HAP server's side, it degrades iOS battery life significantly by waking the device every 15s to respond to these packets. In the case as a normal MQTT client, it increases traffic on top of the 60s keepalive we've already set at the application layer. In both cases, the solution is to just explicitly disable TCP keepalives. Upgrade hap to the latest version that contains the fix brutella/hap#36.
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 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:
-
ListenAddrcan be used to bind to a specific port and/or address, useful for selecting a fixed port for firewall rules. -
Interfaceslimit which interfaces mDNS broadcasts appear on, and which addresses to use when broadcasting.
These settings are optional and can be left blank.
