go-home

Automated home using Go.

Raspberry PI

gokrazy.org, a Go only OS for Raspberry PI.

Status

I am currently running this in the weekend, still testing some sub-processes and now focussing on Apple Home-Kit interaction so that we have an actual UI.

App Structure

Note: InfluxDB for tracking metrics and usage of some processes. Since all of this is written in Go it should be able to run anywhere, from a Raspberry PI, Arduino to a Windows/Mac machine.

  • Since every process is just running it's own logic want we need is a pub/sub server where every process can register itself to specific events that it is interested in. -> NATS Server (Pub/Sub server where you can subscribe to channel(s)) -> Researching the possibility of using zeroconf 'Service Discovery - mDNS'

  • Following sub-processes:

    • Apple HomeKit WIP, (Apple Home Kit accessory emulator, our UI solution)
    • Conbee II DECONZ Ok, (Philips HUE / IKEA / Xiaomi Aqara; lights, switches, sensors)
    • Wemo Ok, (Wemo wifi powerplug)
    • Config Ok, (A service that is the provider of configurations for all other services)
    • Presence Ok, (Connects to Netgear Router to obtain list of devices present on the network)
    • Flux Ok, (Calculates Color-Temperature and Brightness per day for Hue and Yee lights)
    • AQI Ok, (Air Quality Index)
    • Suncalc Ok, (Computes sun-rise, sun-set etc..)
    • Weather Ok, (Darksky)
    • Calendar Ok, (Reads calendars from icloud and determines active events and makes sensors out of them)
    • Shout Ok, (Has Slack as the back-end to send messages, but requires a VPN :-(, looking for something else)
    • Yee Ok, (Xiaomi Yee lighting, turn on/off, change CT and BRI)
    • Sony Bravia Remote Ok, (Turn on/off, HDMI Input, Volume for Sony Bravia TV(s))
    • Samsung TV Remote Ok, (Turn on/off Samsung TV(s))

Automation Logic

Automation, reacting to all events and executing automation rules, all written in Go.
