Project Overview

• Remote Outlet Management System (ROM System)• An affordable Home Automation System

• Key Features:• Power Monitoring• Continuous streaming of device power consumption to database• Ability to view data in a variety of ways

• Device Monitoring• Will be able to see which devices are on/off• Be able to see a time based diagram of device activity

• Ability to turn devices on or off• One click will turn the device on/off• Will be able to set a schedule that the device will follow

• 4 Main Components• ROM Plug-In• There will be a microcontroller and associated circuitry used

to monitor power, device activity, and turn the device on/off• Main Hub• A microprocessor will run the server, receive data from the

ROM Plug-Ins, and route commands from the user• Database• All of the data will be stored here, along with user login data

and the framework for the website• Website/App• Will facilitate user access to the system and allow ease of

use to the key features of the system

• A majority of our parts have arrived• Basic database functionality has been created• Raspberry Pi has been set up with Raspbian

Distro and configured to work with the database• MSP430s are here, and Code Composer Studio

has been downloaded• The app has a storyboard and partial data

model• Power Supply and Current Sensing circuits are

partially complete

Work Performed to Date

Database• Login system coded and supports a single user• Minor Error Handling• Interfaces with a functional test site• Backbone of the database is complete, allowing

for modular development of database

Raspberry Pi/MSP430• The Raspbian OS has been loaded on to an SD card

and inserted into the Raspberry Pi• The BIOS has been edited for memory allocation and

the OS has an updated Apache and SQL• The proper database repositories have been

downloaded and set up for integration with the Raspberry Pi• Node.JS, Lineman, NPM, etc.

• Code Composer Studio has been downloaded and basic programs have been tested on it to gain familiarity with the environment

Website/App• User interface is nearly complete.• Login view.• New profile view.• Partial scheduling view.• Device detail view.

• Data model is in progress.• Partial user data model.• Need to implement device data

model. • Attempting to correctly configure

NSURLConnection class. (Depends on specifics requirements of the database code)• This will enable use of the

HTTPURLRequest.

Power• Circuits• Transformerless Power Supply• Current Sensing• Switching Component

• Preparing Circuits

Challenges and Changes• We might have to use a relay switch instead of a

semiconductor device • SOIC vs. PDIP• Triac• Figuring out how to query a database through

the app• Website is not running on a PHP background,

but rather AngularJS, so we can utilize the functionality of Node.JS

• Not having all of the parts in prevents testing

Checklist for Next Milestone• X-Bee should arrive (Start integrating those into the

system)• Get two devices to talk to each other with simple

messages (ROM Plug-In <-> Main Hub)

• Integration between App and database (Able to influence database through app)

• Current measuring circuit complete• Able to read correct current data through the ROM

Plug-In (ADC working correctly)• Switching circuit complete• Can send a signal from MSP430 to “flip the switch”

• Have PCB design ready to be constructed• Smart Plug-In and Central Hub Housing dimensions

defined
