Smart Things + Home Assistant: build your own smart home

Slides for pycon Taiwan 2018

Our world will be composed of more and more connected devices. Smart things will enrich our life started from our home. However, with no standard in place for communication, devices are unable to recognize to each other and work together well.

An open source project, "Home Assistant", brings us into the practical home automation world. Building on Python, the home automation platform was implemented to take control of their houses, their data, and their privacy. In this talk, I will start by introducing a concept of home automation, the general concept of "Home Assistant" and it's components. Then, a sample demo will bring you a real scenario along with introducing configurations.

1. Smart Things + Home Assistant: build your own smart home Shuhsi Lin PyContw 2018
2. About me Data engineer in a manufacturing company Working with • data and people Focus on • Streaming process • IoT applications • Engineer culture Shuhsi Lin Lurking in PyHug, Taipei.py and various Meetup sucitw gmail.com
3. • Smart home/home automation ◦ What makes home automation hard • Introduction of home-assistant ◦ Basic concept of home-assistant ◦ Architecture of home-assistant • How to build your home automation system ◦ Environment setup ◦ Configuration ◦ Possible scenario • Summary What I will share today 3
4. • Hacking hardware ( The next speaker may take care !?) • Basic configurations and use on Raspberry Pi • Compare ecosystems for Amazon Alexa/ Google home/ Apple HomePod/ Mi home ….. • Much source code What I will not focus ( aka I don’t know) 4
5. Smart Home
6. Smart Things 6 home control home automation smart home location and time-based events communicate with each other at home
7. 7 Internet of Things Home Control Information (ex, light is on) Commands (ex, turn light on) Home Automation: Start from a hub User Information Commands State • Light = on ◦ Brightness: 120 ◦ Color: Yellow • Sensor value ◦ Temperature: 32 oC • Switch ◦ Power: turn_on Event • State of switch has changed ◦ Off -> on • Motion detected • Remote control TV
8. IFTTT IFTTT IFTTT IFTTT IFTTT IFTTT IFTTT IFTTT … Recipe if this then that Trigge r Action
9. Home Automation Landscape 9 Internet of Things Home Control User Information (ex, light is on) Commands (ex, turn light on) Information Commands Information Commands Information Commands Home Automation Smart Home Rules (Configuration) Home Control, Automation & the Smart Home
10. •More IoT devices with different protocols •Many own apps •More data •More scenarios •Privacy and trust •Easy to use Challenges 10 https://www.home-assistant.io/blog/2014/12/26/home-control-home-automation-and-the-smart-home/
11. Home Assistant • Open source, Python 3 • Active Community ◦ 2 weeks release cycle ◦ Chatrooms, forums, videos • Supported many and many devices • Configuration-based ◦ Automation with no code change • Cross platforms • Local or remote and cloud is optional
12. Developer documentation https://developers.home-assistant.io/en/
13. • Platforms ◦ Types of devices (ex, lights, sensors) • Components (> 1000) ◦ Interact with an Internet-of-Things domain ▪ MQTT, Zwave, Zigbee ▪ Lights (Hue, Tradfri) ▪ Sensors ◦ Respond to events that happen within Home Assistant ▪ Small pieces of home automation logic or involve services that do common tasks within your house. ▪ ex, device_sun_light_trigger component Wording in HA Event Bus: facilitates the firing and listening of events -- the beating heart of Home Assistant. State Machine: keeps track of the states of things and fires a state_changed event when a state has been changed. Service Registry: listens on the event bus for call_service events and allows other code to register services. Timer: sends a time_changed event every 1 second on the event bus

22. Getting-Started
23. Getting-Started Installation (Raspberry Pi 3 , Linux or Mac) Configuration (Connect devices) Automation (Use it)
24. Installation On Raspberry Pi 3 1. Raspbian 2. Hassbian 3. Mossbian (Chinese) 4. Hass.io use this • HA UI • Ready to use (integrated 3rd part applications) • Easy to install and update (ResinOS and Docker) • Easy to extend by Hass.io add-ons (Goolge Assistant...) Home Assistant 0.70.0
25. HOME ASSISTANT and HASS.IO https://www.home-assistant.io/blog/2018/04/22/hassio-2018/ https://developers.home-assistant.io/docs/en/architecture_hassio.html ResinOS

31. Automation by built-in components
32. Hey, Google
33. Home Assistant Cloud • Google Assistant (Google Home) • Amazon Alexa (Amazon Echo) https://www.home-assistant.io/cloud /
34. Possible Scenario 34 Mi Home (China version) (gateway) text-based Google Assistant working on Hass.io Home Assistant Cloud $5 USD/month ? yicamera (hacked)
35. • Smart Home ◦ No standard/universal communication way between smart things (so far) • Home assistant ◦ as a Developer ◦ as a User • Hassio • Home assistant cloud Take Home Messages
