“Control the World”

• “Turn off all the lights in the basement”

• “Heat the stove to 350°F”

• “I’m going to bed” - turn of the lights, close the blinds, set the “at home” alarm

• “Watch Apple TV” - turn on the TV, set to HDM12, turn on Apple TV


Solve “the Basket Full of Remotes Apps

Problem”



The IOTDB Database

• The IOTDB describes:

• how to control things

• what things are

• where things are

• … and eventually more


IOTDB Code

• Uses the IOTDB Database

• Cross platform

• Node, iOS, Android, Python...


Main Concepts


Models

• A shared descriptions of things

• A Phillips Hue

• A WeMo

• A Bluetooth Smart kettle

• GitHub like updating model


Places

• Where I put things

• Unique to me

• Lightly structured

• My Bedroom on the 2nd floor

• The kitchen


Devices

• Unique to me

• Actual things - with a Model and Place(s)

• My Phillips Hue, in the front porch

• My Bluetooth Kettle, in the kitchen


Attributes

• A vocabulary of how to control devices

• “on” - turn it on or off

• “channel” - the channel

• “temperature”…

• Also sensing and notification


Facets

• A vocabulary of what devices do

• lighting

• climate control / heating / cooling

• appliance

• toy

• …


“me” / my account

• Everyone gets their own IOTDB account which describes “their world”

• Share your world with others in a controlled fashion


What it does


Warning!Pseudocode

• This is what developers see

• End users will get apps, programs…

• Names starting with “_” are shorthands (don’t worry about it too much!)


“Turn off the lights in the Kitchen”

iot .things() .room(“Kitchen”) .select(“lighting”) .set(“_on”, false)


“Put the stove to 350”

iot .things() .named(“Kitchen Oven”) .set( “_temperature”, _fahrenheit(350) )


Describes data

• pulse means heartbeats per second

• speed is speed in km/h

{ “pulse”: 130 “speed”: 6.7}


What IOTDB is not


Not a cloud service!

• The IOTDB doesn’t control things … it describes how to control things

• but we has software to use these descriptions


Not (another) protocol!

• There’s lots of great protocols and efforts out there

• MQTT, CoAP, …

• Allseen, SkyNet, …

• Bluetooth Smart, ZigBee, Z-Wave

• The world doesn’t need another



Not just about the home

• Can describe anything you want

• The power of Linked Data

• Everything is IRIs


Not Magic

• Something still has to do the heavy lifting!

• IOTDB describes how to operate things

• Software does the work (send Bluetooth or ZigBee messages, UPnP connects, etc.)

• Batteries included - we provide code

What Problems Does IOTDB Solve?


Description

• Solid semantic description of all Things

• what it does

• how is does it

• where it is

• Interfaces can be built by Introspection


Discovery

• Very tricky identity issues

• MAC address availability

• BLE UUID: vendors don’t play by rules

• Same IP on different NATted LANs


Integration

• “Bypass Standards” - we’re in the Internet Video era

• This is how we solve the “Basket of Remotes” issue


Composite Objects

• e.g. a Stove consists of many sub-things

• 4 burners

• a clock

• an oven

• an oven light


Cross-platform

• Models encapsulate in JSON-LD how things work (&c)

• a small amount of glue JavaScript needed

• intended to go to mobile, especially Android & iOS


Distribution

• Everything can be downloaded at will

• including Models!

• Models can be forked & merged

• github model

• Everyone controls their own “worldview”


What I’m looking for


IOT Enthusiasts

• Owners of WeMos, Lutrons, Bluetooth Smart, Quantified Self, SmartThings, …

• Looking to try something new

• People who are comfortable with Node


Hardware Makers

• Who don’t want to write apps


Community

• People passionate about the IOT

• Developers who want to work with (or with me)


Where this going


IOTDB.org website

• Alpha - users by invite only

• Beta - wider (but controlled) release


Software

• Node-JS Release

• Desktop Application

• Android

• iOS


There’s far more to the IOTDB than this

…for another time
