[Part 3] automation of home appliances using raspberry pi – all set to automate the home appliances

Intro
Azilen is back with the third blog of its Automation of Home Appliances using
Raspberry Pi. The first and second blogs of this series were more about
technology set up such as Software Installation Guide and Implementation of
Hand Gesture Recognition. Third blog is more about command configuration set
up and user oriented real time demo of application which is actually a captive
portal type application designed to automate home appliances.

Technological Overview – How We Created it to be
a Captive Portal
• As the user can have remote access to application, we hosted the
application at Raspberry PI server.
• Though spring boot is known for making notable amount of reduction in
writing a lot of configuration and boilerplate code, its auxiliary niceties of
being light weight and the caliber of packaging the application as a
runnable jar that includes an embedded tomcat server attracted us more
for its consideration for our application and its REST endpoints also
helped us in making the application accessible through browser.
• Application package comes in executable jar format such as and it has
configured system settings that help to start the web server on Raspberry
PI startup without any user interaction.
• A user friendly application flow which is described in Real Time Demo of
Application section could be achieved through prominent utilization of
spring boot capabilities.

How does the user manage application set up?
This is a plug and play set top box look like solution intended to easy
installation and operation. User just simply needs to supply electric power
through cable to access it.
Elementary application access
• We have tried to make the application access handy as much as we could.
• Once the user plugs in our set top box look like device and connect to the
home WiFi network, system UI will automatically open up in each laptop
or mobile device which are connected with that particular WiFi network
and enable the user to manage his home appliances through them.
• We have used Captive Portal concept for implementing this functionality
and of course, it needs successful WiFi access permissions like SSID and
Password or any configured hint.
• Then the url of application will be saved in browser so that user can
manually ping the system.

How It Works?
Once the user starts the application, it will check “Smart IR Device” has
connected or not, according the device status application show message. If it
is connected, system will go ahead otherwise it will display the error message
and in that case, the user needs to configure smart IR device by providing
WiFi user ID and Password. This process is called ‘Smart Config’.

Once IR device gets connected application will confirm you it by message and
will navigate you to the home page.

Learning Mode to make the Device Learn
Learning Mode is all about making the IR device understand that which
gesture or numerical input to be considered for performing desired action
and accordingly IR device will pass the signals to connected home appliance.
For manual Input set up application will display a dashboard with configured
options and for gesture input set up, you can enable device camera and
capture the gesture by using Start Capture and Stop Capture buttons. Once
gesture is configured, you can link that gesture to the desired on off etc.
actions.

Execution Mode to Implement the Actions
Once gestures are configured and linked with relevant actions, they can be
executed anytime. To execute it, user simply needs to assess the application
and capture the gesture using Take Snapshot.

Manual inputs can be executed by using number keys.
Help section is also the part of application to guide the user so that he can
use the application flawlessly.

Conclusion
Of course, this accomplishment has certainly boosted our techie spirit up to
optimum level. Still, while the world is advancing swiftly towards Internet of
Things, and people are looking forward to high end and affordable
technological experience in routine life, Azilen believes that there is a long
way to go. Many more advancements are still on the way for us.
