Consumers face unacceptable performance as nodes are increased and network bandwidth is consumed in physically constraining environments. Various network types and use cases, thus, are explored to determine current failure points in common IoT home smart devices. 2. Introduction At the time of this report, there has been an unprecedented uptake in the use of ‘smart’ devices in the home. The introduction of voice recognition platforms such as Google Home and Amazon Alexa has fueled the use of small, inexpensive, connected sensing and control devices. Controls for Heating and Air Conditioning have been popular, as well as various sensors for doors, windows, etc.. Perhaps the most pervasive has been the acceptance of these types of systems for lighting control. Due to the sheer number of nodes available in a home, lighting nodes to be controlled is very large. This research will focus on various types of network technologies with the goal of physically simulating small to large sets of devices to determine acceptable response time.

  • Security Evaluation of the Z-Wave Wireless Protocol
    Security Evaluation of the Z-Wave Wireless Protocol Behrang Fouladi Sahand Ghanoun SensePost UK Ltd. [email protected] [email protected] Abstract — The Z-Wave wireless communication protocol has ZigBee protocol with regards to home automation. This is been widely used in home automation and wireless sensors partly due to interoperability of devices and shorter time to networks. Z-Wave is based on a proprietary design and a sole market on the vendor side. Another benefit is that it is less chip vendor. There have been a number of academic and subjected to signal interference compared to the ZigBee practical security researches on home automation systems based protocol, which operates on the widely populated 2.4 GHz on ZigBee and X10 protocols, however, no public vulnerability research on Z-Wave could be found prior to this work. band shared by both Bluetooth and Wi-Fi devices.

  • Required Submission Information for Each Award
    I. Market Overview The network system protocols market closely follows the trends in home and building automation markets. Home and building controls can effectively be performed through wireless and powerline platforms. In addition, several manufacturers produce systems based on proprietary protocols. Any changes in the home or building automations markets have a direct impact on the market demand for these platforms. The residential segment forms a major portion of the application for these platforms, driven by a growing awareness about the benefits rendered through home automation. In 2005, revenues for the North American home automation market were estimated at $1,268.9 million and the market is expected to witness steady growth in the future. As a result of this, the protocols market is also experiencing healthy growth. Another crucial trend in this industry is the developing shift from proprietary platforms to open ones, which offers interoperability and more flexibility to end- users. The industry is also witnessed an increasing interest in wireless solutions, which in turn has driven the markets for radio frequency (RF) platforms. Although wireless solutions have been able to make some headway in the home automation market, some critics remain unconvinced of their effectiveness in terms of reliability. On the other hand, powerline communication offers more reliability and an extended reach. Hence, there is a need for simple and affordable protocol that can offer the benefits of both RF and powerline platforms. Moreover, the use of this open platform is likely to enable end-users to choose from a range of products, which is not feasible when using native or proprietary platforms.

  • Getting Started with HCA and X10
    Getting Started with HCA and X10 This Getting Started Guide continues from the previous “Getting Started with HCA – Installation and Introduction” which covers installing HCA and the basic operations available from the ribbon. This guide assumes that you have reviewed that. In this guide these topics are covered. • Connecting an X10 capable interface to HCA • Creating a new design file • Adding X10 devices using the HCA Designer • Controlling devices from the HCA user interface • Scheduling a device to come on at sunset • Responding to a button press on a keypad If you have not already purchased HCA and you are looking to test drive this software, you can download a free 30-day trial of HCA Plus from the HCA support website at www.HomeControlAssistant.com. Connecting the X10 interface to HCA Before HCA can control X10 devices in your home, you must connect an interface to your computer. There are several different interfaces that can send and receive X10 signals. We recommend that you use the Smart Home PowerLinc model 2413. The advantage of that interface is that it can send and receive both the older X10 signals and the newer Insteon signals. That lets you use your existing devices but add newer ones and be able to control both. Instructions for installing the 2413 PowerLinc can be found in the Getting Started with HCA and Insteon guide. You can also use the older CM11 and CM15 interfaces. The CM11 is a serial interface and can be connected to the computer and the communications port it uses is specified in the HCA hardware setup.

  • Smart Homes and the New White Futurism
    Journal of Futures Studies 2021,Vol. 25(4) 45–56 DOI: 10.6531/JFS.202106_25(4).0004 Article Smart Homes and the New White Futurism Adam Richard Rottinghaus1,* 1Assistant Professor of Media, Journalism & Film, Miami University, Williams Hall, 208, 350 Oak Ave., Oxford, OH, 45056, USA Abstract This article explores the consumer technology industry’s discourse about emerging Internet of Things smart home devices and sketches an outline of a “new white futurism.” New white futurism displaces prior consumer fantasies of labor-free living in smart homes and frames emerging smart home devices as tools for data-driven management of work/life balance in contemporary heteronormative, white, middle-class culture. The research draws on existing scholarly literature, archival documents, contemporary marketing discourses, and participant observation at CES in 2014 and 2018. The article concludes that it is crucial to reimagine cultural relationships to emerging technologies through Afro, Indigenous, and queer futuristic thought. Keywords Smart Homes, Emerging Technologies, Internet of Things, Futurism, Labor, Corporate Power This article explores the consumer technology industry’s discourse about emerging smart home devices and begins sketching the outlines of a “new white futurism.” New white futurism is a discourse from companies that promotes emerging smart home technologies as tools for data-driven management of work/life balance in contemporary heteronormative, white, middle-class culture. Since 2008 the consumer technology industry has increasingly focused on the Internet of Things (IoT) and connected smart homes as the dominant retail application. IoT smart home devices have precipitated a shift away from promoting imaginative technological futures that bring about changes in labor or culture in everyday life toward one of logistics and management that reproduce the status quo.

  • X10 Debugging Tips
    X10 DEBUGGING TIPS INTRODUCTION Although X10 powerline communications provides many great benefits, one of its biggest downsides is the potential reliability problems. In fact, the most frequent questions we receive from HomeVision users are about X10 problems in their homes. Over the years we’ve learned some good ways to help isolate these problems. We hope that these tips will help if you run into X10 problems, even if you’re using a different home automation system. Problems can generally be grouped into two categories: 1. Major problems: X10 never works 2. Intermittent problems: X10 sometimes works There are many possible things that can cause such X10 problems. We will discuss troubleshooting the major problems, then address the much more common intermittent X10 problems. SOLVING MAJOR X10 PROBLEMS Let’s start with the worst-case scenario: HomeVision is neither sending nor receiving X10 commands. In this situation, the problem lies in one of four places: 1. The HomeVision controller. 2. The X10 powerline interface device. This is usually a TW-523 or PSC05, although there are others. We’ll refer to all of them as “TW-523” in this article. 3. The cable connecting the HomeVision controller to the TW-523. 4. A serious X10 signal degradation problem in your home. So how do we troubleshoot these? Here goes … Check the TW-523 Module LED First, verify that the red LED on the TW-523 module is lit. If not, make sure it’s plugged into a live circuit. If the LED is still not lit, then the TW-523 is defective.
