Home automation in the context of "Roku, Inc."

A home server is a computing server located in a private computing residence providing services to other devices inside or outside the household through a home network or the Internet. Such services may include file and printer serving, media center serving, home automation control, web serving (on the network or Internet), web caching, file sharing and synchronization, video surveillance and digital video recorder, calendar and contact sharing and synchronization, account authentication, and backup services.

Because of the relatively low number of computers on a typical home network, a home server commonly does not require significant computing power. Home servers can be implemented do-it-yourself style with a re-purposed, older computer, or a plug computer; pre-configured commercial home server appliances are also available. An uninterruptible power supply is sometimes used in case of power outages that can possibly corrupt data.

Smart thermostats are Wi-Fi thermostats that can be used with home automation and are responsible for controlling a home's heating, ventilation, and air conditioning. They perform similar functions as a programmable thermostat as they allow the user to control the temperature of their home throughout the day using a schedule, but also contain additional features, such as Wi-Fi connectivity, that improve upon the issues with programming.

Like other Wi-Fi thermostats, they are connected to the Internet via a Wi-Fi network. They allow users to adjust heating settings from other internet-connected devices, such as a laptop or smartphones. This allows users to control the thermostat remotely. This ease of use is essential for ensuring energy savings: studies have shown that households with programmable thermostats actually have higher energy consumption than those with simple thermostats because residents program them incorrectly or disable them completely.

Google Assistant is an outgoing virtual assistant software application developed by Google that is primarily available on home automation and mobile devices. Based on artificial intelligence, Google Assistant can engage in two-way conversations, unlike the company's previous virtual assistant, Google Now.

Google Assistant debuted in 2016 as part of Google's messaging app Allo, and its voice-activated speaker Google Nest. After a period of exclusivity on the Google Pixel smartphones, it was deployed on other Android devices starting in February 2017, including third-party smartphones and Android Wear (now Wear OS), and was released as a standalone app on the iOS operating system in May 2017. Alongside the announcement of a software development kit in April 2017, Assistant has been further extended to support a large variety of devices, including cars and third-party smart home appliances. The functionality of Assistant can also be enhanced by third-party developers. At CES 2018, the first Assistant-powered smart displays (Smart speakers with video screens) were announced, with the first one being released in July 2018. In 2020, Google Assistant was already available on more than 1 billion devices.

A smart device is an electronic device, generally connected to other devices or networks via different wireless protocols (such as Bluetooth, Zigbee, near-field communication, Wi-Fi, NearLink, Li-Fi, or 5G) that can operate to some extent interactively and autonomously. Several notable types of smart devices are smartphones, smart speakers, smart cars, smart cards, smart thermostats, smart doorbells, smart locks, smart refrigerators, phablets and tablets, smartwatches, smart bands, smart keychains, smart glasses, smart TV, and many others. The term can also refer to a device that exhibits some properties of ubiquitous computing, including—although not necessarily—machine learning.

Smart devices can be designed to support a variety of form factors, a range of properties pertaining to ubiquitous computing and to be used in three main system environments: physical world, human-centered environments, and distributed computing environments. Smart homes indicate the presence of sensors and some detection devices, appliances, and a database to control them.

A voice-user interface (VUI) enables spoken human interaction with computers, using speech recognition to understand spoken commands and answer questions, and typically text to speech to play a reply. A voice command device is a device controlled with a voice user interface.

Voice user interfaces have been added to automobiles, home automation systems, computer operating systems, home appliances like washing machines and microwave ovens, and television remote controls. They are the primary way of interacting with virtual assistants on smartphones and smart speakers. Older automated attendants (which route phone calls to the correct extension) and interactive voice response systems (which conduct more complicated transactions over the phone) can respond to the pressing of keypad buttons via DTMF tones, but those with a full voice user interface allow callers to speak requests and responses without having to press any buttons.

A home network or home area network (HAN) is a type of computer network, specifically a type of local area network (LAN), that facilitates communication among devices within the close vicinity of a home. Devices capable of participating in this network, for example, smart devices such as network printers and handheld mobile computers, often gain enhanced emergent capabilities through their ability to interact. These additional capabilities can be used to increase the quality of life inside the home in a variety of ways, such as automation of repetitive tasks, increased personal productivity, enhanced home security, and easier access to entertainment. Other than a regular LAN that are centralized and use IP technologies, a home network may also make use of direct peer-to-peer methods as well as non-IP protocols such as Bluetooth.

Ring LLC is a manufacturer of home security and smart home devices owned by Amazon. It manufactures a line of Ring smart doorbells, home security cameras, and alarm systems. It also operates Neighbors, a social network that allows users to discuss local safety and security issues, and share footage captured with Ring products. Via Neighbors, Ring could also provide footage and data to law enforcement agencies to assist in investigations with user’s consent constraint.

The company was founded in autumn 2013 by Jamie Siminoff as the crowdfunded startup Doorbot; it was renamed Ring in autumn 2014, after which it began to receive equity investments. It was acquired by Amazon in 2018 for approximately $1 billion.

Amazon Echo, often shortened to Echo, is a brand of smart speakers developed by Amazon. Echo devices connect to the voice-controlled intelligent personal assistant service, Alexa, which responds to a wake term (Alexa, and others) when spoken by its user. The features of the device include voice interaction, audio program playback, such as music, streaming podcasts, and audiobooks, maintaining to-do lists, alarms, and scheduling reminders, in addition to providing weather, traffic and other real-time information. It can also control several smart devices, acting as a home automation hub.

Amazon started developing Echo devices inside its Lab126 offices in Silicon Valley and in Cambridge, Massachusetts as early as 2010. The device represented one of its first attempts to expand its device portfolio beyond the Kindle e-reader.

A smart speaker is a type of loudspeaker and voice command device with an integrated virtual assistant that offers interactive actions and hands-free activation with the help of one "wake word" (or several "wake words"). Some smart speakers also act as smart home hubs by using Wi-Fi, Bluetooth, Thread, and other protocol standards to extend usage beyond audio playback and control home automation devices connected through a local area network.

Cox Communications, Inc. (also known as Cox Cable and formerly Cox Broadcasting Corporation, Dimension Cable Services and Times-Mirror Cable), is an American digital cable television provider, telecommunications and home automation services company. It is the third-largest cable television provider in the United States, serving approximately 6.5 million customers. It is also the seventh-largest telephone carrier in the country, serving 3.5 million Internet subscribers and almost 3.2 million digital telephone subscribers. Cox is headquartered at 6205 Peachtree Dunwoody Rd in Sandy Springs, Georgia, U.S., in the Atlanta metropolitan area. It is a privately owned subsidiary of Cox Enterprises.

Zigbee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios, such as for home automation, medical device data collection, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection. Hence, Zigbee is a low-power, low-data-rate, and close proximity (i.e., personal area) wireless ad hoc network.

The technology defined by the Zigbee specification is intended to be simpler and less expensive than other wireless personal area networks (WPANs), such as Bluetooth or more general wireless networking such as Wi-Fi (or Li-Fi). Applications include wireless light switches, home energy monitors, traffic management systems, and other consumer and industrial equipment that requires short-range low-rate wireless data transfer.

Google Nest, formerly branded Google Home, is a line of smart home products including smart speakers, smart displays, streaming devices, thermostats, smoke detectors, routers and security systems including smart doorbells, cameras and smart locks.

The Nest brand name was originally owned by Nest Labs, co-founded by former Apple engineers Tony Fadell and Matt Rogers in 2010. Its flagship product, which was the company's first offering, is the Nest Learning Thermostat, introduced in 2011. The product is programmable, self-learning, sensor-driven, and Wi-Fi-enabled: features that are often found in other Nest products. It was followed by the Nest Protect smoke and carbon monoxide detectors in October 2013. After its acquisition of Dropcam in 2014, the company introduced its Nest Cam branding of security cameras beginning in June 2015.

Power-line communication (PLC) is the carrying of data on a conductor (the power-line carrier) that is also used simultaneously for AC electric power transmission or electric power distribution to consumers.

A wide range of power-line communication technologies are needed for different applications, ranging from home automation to Internet access, which is often called broadband over power lines (BPL). Most PLC technologies limit themselves to one type of wires (such as premises wiring within a single building), but some can cross between two levels (for example, both the distribution network and premises wiring). Typically transformers prevent propagating the signal, which requires multiple technologies to form very large networks. Various data rates and frequencies are used in different situations.

X10 is a protocol for communication among electronic devices used for home automation (domotics). It primarily uses power line wiring for signaling and control, where the signals involve brief radio frequency bursts representing digital information. A wireless radio-based protocol transport is also defined.

X10 was developed in 1975 by Pico Electronics of Glenrothes, Scotland, in order to allow remote control of home devices and appliances. It was the first general purpose home automation network technology and remains the most widely available.

Google Nest, formerly known as Google Home, is a line of smart speakers developed by Google under the Google Nest brand. The devices enable users to speak voice commands to interact with services through Google Assistant, the company's virtual assistant, and with a touchscreen display on some models. Both in-house and third-party services are integrated, allowing users to listen to music, control playback of videos or photos, or receive news updates entirely by voice. Google Nest devices also have integrated support for home automation, letting users control smart home appliances with their voice command. The first device, Google Home, was released in the United States in November 2016; subsequent product releases have occurred globally since 2017.

Through software updates to Google Nest devices and Google Assistant, additional functionality has been added over time. For example, multiple speakers can be set up for synchronized playback of music. An update in April 2017 brought multi-user support, allowing the device to distinguish between up to six people by voice. In May 2017, Google announced multiple updates, including: hands-free phone calling at no cost in Canada and the United States; proactive reminders ahead of scheduled events; visual responses on mobile devices or Chromecast-enabled televisions; Bluetooth audio streaming; and the ability to add reminders and calendar appointments.
