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.
