1. Exploring Your Smart Home Data Shuhsi Lin Taichung.Py 2019
2. Lurking in PyHug, Taipei.py and various Meetup About Me 2 Scrum Master + Data Engineer in a manufacturing company Working with • data and people Focus on • Agile/Engineering culture • Streaming process • IoT applications • Data visualization Shuhsi Lin sucitw gmail.com https://medium.com/@suci/
3. • Smart home/home automation ◦ What makes home automation hard • Introduction of home-assistant ◦ Basic concept and Architecture • How to build your home automation system ◦ Environment setup/Configuration/Possible scenarios • Explore Your Data ◦ Data, libary, and examples • Summary What I Will Share Today 3
4. • Hacking hardware • Basic configurations and use on Raspberry Pi • Compare ecosystems for Amazon Alexa/ Google home/ Apple HomePod/ Mi home ….. • Too many source code What I Will not Focus ( aka I don’t really know) 4
5. Look familiar?

8. Smart Home
9. Smart Things communicate with each other at home 9
10. Home Control Home Automation Smart Home location and time-based events 10 connect and control devices Photo by Samuel Zeller on Unsplash
11. 11 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
12. IFTTT IFTTT IFTTT IFTTT IFTTT IFTTT IFTTT IFTTT … Recipe if this then that Trigger Action

14. •More IoT devices with different protocols •Many own apps •More data •More scenarios •Privacy and trust •Easy to use Challenges 14 https:/ /www.home-assistant.io/blog/2014/12/26/home-control-home-automation-and-the-smart-home/

18. 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
19. Developer documentation https://developers.home-assistant.io/en/
20. • Platforms (collection) ◦ Types of devices (ex, lights, sensors) • Integration/Components (> 1400) Responsible for a specific domain within Home Assistant. ◦ 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

28. Getting-Started
29. Getting-Started Installation (Raspberry Pi 3 , Linux or Mac) Configuration (Connect devices) Automation (Use it)
30. 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
31. 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
32. http://localhost:8123 Home Assistant UI
33. Configuration Hass.io: /config (~/.homeassistant/configuration.yaml) https://www.home-assistant.io/getting-started/configuration/
34. ADD-ON
36. ssh key
37. Automation by built-in components
