Home Automation
Example
AWS Greengrass can
run on a home
gateway such as a
router so that the
lighting system, TV,
and Echo continue to
operate even if
connection to the
cloud is lost.
Smart TVs can connect to
AWS IoT Core to take
advantage of a fully scalable
cloud backend that provides
easy integration with Alexa.
Amazon FreeRTOS provides
security, connectivity, and
updateability for devices
running on microcontrollers,
like a light bulb so it can
respond to voice commands.
AWS IoT Device Management,
AWS IoT Device Defender,
and AWS IoT Analytics
provide added benefits such
as remote device
management, monitoring,
security, and insights into
device usage.

AWS IoT Core supports MQTT, a lightweight
communication protocol designed to tolerate
intermittent connections, minimize the code
footprint on devices, and reduce network
bandwidth requirements.
With AWS IoT Device Management, you can
onboard, organize, and monitor all of your
devices, creating a real-time fleet index, and
remotely manage devices with over-the-air
updates.
AWS IoT Core provides scalable, low latent
bi-directional communication from device to
cloud with availability in 11 regions
worldwide.
Why Use AWS IoT For Home Automation?
Built-in connectivity
Device security
Offline communication
Over-the-air updates Devices running AWS Greengrass and Amazon
FreeRTOS can be updated over-the-air, for
security updates, bug fixes, and new feature
updates.
AWS Greengrass enables connected devices
to operate with intermittent connectivity to
the cloud—synchronizing the data whenever
connection is re-established.
AWS IoT provides end-to-end authentication
and encryption of device data, key
management, and code signing for OTA
updates.
Reliable & persistent communication
Responsiveness
Device management
Device insights
Low total cost of ownership
With AWS IoT Analytics, you can keep track of
error logs, troubleshoot remotely, perform
predictive maintenance, and gain valuable
customer insights.
The AWS IoT service suite enables a faster
time-to-market and eliminates the need to
build expensive, custom in-house
infrastructure.
Amazon FreeRTOS, an IoT operating system
for microcontrollers, provides libraries for
security & connectivity in a tiny memory
footprint.

Why Use AWS IoT with Voice Assistants?
Ease of implementation
Cloud enabled bi-directional communication
Seamless Interoperability between
Alexa skills and AWS IoT
Insights into users
AWS IoT acts as a liaison between
Alexa Cloud and your devices.
AWS IoT allows you to easily
analyze and gain insights for device
actions within the home.
AWS IoT acts as a liaison between
Alexa Cloud and your devices.
With AWS IoT you can have a
voice enabled backend solution
running within a matter of
weeks.
