Presentation I gave at the Austin IoT Hardware Sub-Group about IoT Domain Naming and Pain Points associated with IoT Devices

1. Austin IoT Hardware Sub-
Group
Overview - Naming - Pain points
1 - 03/09/2015

2. About The Austin IoT Sub-Group
The IoT Hardware Sub-Group offers a more hands-on
approach than it's broader based parent, the Austin IoT
group.
Meetups will feature show-and-tell demonstrations,
collaborative discussion, and educational presentations.
The focus is on learning how to create IoT devices, for fun
or profit. Most of all, we will have fun! with IoT.

5. Internet of Things?
● Internet
○ A way to communicate
● Things
○ Things that can communicate

6. IoT Domains
● IoT Device
● IoT Server
● IoT Client
● IoT Security

7. IoT Device
● Internet connected
○ Observation
○ Control
○ Both

8. Device Example: Garage Door Node
● Observation
○ Door state (open or closed)
● Control
○ Presses door control button

9. IoT Server
● Device Communications
● Data Storage
● API interfacing
● Applications (Web based)

10. Server Example: Garage Door Node
● Device Communications
○ Talks directly to the device over the net(!)
● Data Storage
○ Stores a history of events
● API interfacing
○ Provides access to device communications or status
and history data.
● Applications (Web based)
○ Serves up web applications which use the API.

11. IoT Clients
● Applications working with devices
● Mobile, Desktop, or Web
● Third party systems
● Other Devices.

12. Client Example: Garage Door Node
● Application
○ Mobile iOS, Android, Web
○ PC, Mac, Linux
● Communicates with the Server
○ Reads door status
○ Sends command to move door
○ Alerts User, has pretty GUI

13. Security
Privacy
Crime
Griefing/Hacking
Manufacture Tracking

14. IoT Pain Points
● Server requirement
○ Communications proxy
○ Central clearing point for data
● Device Datalink
○ Configuration
○ Power
○ Cost
● Interoperability
○ OEMs proprietary systems
● Opportunity Knocks

15. Device Pain Points - Datalink
● Wired
○ Ethernet
○ Power Line
○ Custom
● Wireless
○ Wifi
○ Bluetooth
○ Cellular
○ Private - Gateway/Bridge

16. Wired Data-Link
● Ethernet
○ Easy to use thanks to DHCP
○ Requires some power and cost
● USB
○ Cabled to a PC. OK for some applications
○ Lame option in modern times
● Other
○ Powerline
○ Serial

17. Wifi Data-Link
● Configuration - Connecting a device to a home’s wifi
○ Temp Access Point or Soft AP
○ Tricky Electric Imp method with photo detector
○ Temporary connection for configuration
■ Bluetooth, USB, etc…
● Power
○ WiFi needs power, short battery life
● Cost
○ WiFi cost more than $2 today.

18. Cellular Data-link
● Connects like a cell phone
● Hardware Cost
● Subscription Service
○ $3/month plans
○ Spark Electron

19. Wireless Gateway/Bridge
● Low cost radio link between device and base
● Cost is low
● Power is low
● Requires a base unit
○ AC powered
○ Ethernet connected

20. Experimenting with IOT
● Device
○ Use your PC, it’s connected to the internet
■ Use an Arduino or similar
● sensors and controls
○ Smart Phone
○ Raspberry Pi, Beaglebone, others with either wifi or
Ethernet
● Server
○ Try Nodejs.
○ Use existing

21. Existing IoT Servers
PaaS providers for IoT

And more and more…

24. Dweet Demo
● Dweet Service
○ Simple - HTTP GET
○ Easy for Client Web Apps
■ JSON
○ Easy for devices with TC/IP and HTTP stack
● Demo
○ IPhone as device using Freeboard demo app
○ Web app in Brackets on my PC for client
○ Freeboard demo
