The phrase smart home refers to home automation devices that require internet access and a logon account to work properly. Home automation, a broader category, includes any device that can be monitored or controlled via wireless radio signals. Smart home devices have become common for voice recognition, lighting, keyless door entry, security cameras, sensors (for temperature, motion, water, etc.), on/off switches, thermostats, TV's and streaming devices, smoke detectors, robotic vacuum cleaners, lawn watering systems, and many more. Whether the device is powered by the electrical grid or by battery, if it uses the home Wi-Fi network and if an internet logon needs to be created to use it, then it is smart home technology.
Collectively, all the smart home devices on every home's Wi-Fi network helps to make up what is called the Internet of Things (IoT), a huge sea of devices potentially available for remote access and thus potentially available for spying or hacking. Today, homes may contain dozens or even hundreds of such devices, and consumers may enjoy their benefits while knowing little about how they work, or even realizing that they are present.
Not all home automation is "smart home"
Many wireless and automated devices in the home do not require either Wi-Fi or a smart phone, never require internet access, and are not considered to be "smart home" devices because they do not form a part of the Internet of Things (Iot). Examples are a wireless doorbell, a battery-operated wildlife camera with Bluetooth file transfer to a computer, a programmable thermostat that is programmed on the device itself and does not require Wi-Fi, keyless car entry, and garage door openers. Such devices may have microprocessors and radios in them, but they have no internet connections and no need for a logon account. However, they may still have very serious security risks associated with them, as their control signals can be hijacked by bad actors with the right radio signaling technology available, or simply by getting hands on the remote control. Garage door openers are of particular note in this regard.
Modern automobiles, in fact, are full of automation similar to home automation, and cars are hackable by bad actors in a number of way. See Wikipedia's Automotive hacking article for more infromation.
A jungle of incompatible and competing products
At present, consumers must make sure that the smart device they wish to use is specified to be compatible whichever phone/tablet operating system they use (Apple vs. Android). Since smart home products emerged in the absence of any standard, a morass of competing methods for networking, control and monitoring now exist. Consumers may need to buy special hubs specific to one vendor, and products performing the same function are typically not interoperable. Consumers may need to open a different app on their smart phone or tablet in order to control devices by each manufacturer. This makes it expensive and awkward to try out competing devices, leaving consumer stuck with the product they bought originally or else having to add yet more apps to their phones for complete control of everything.
Serious security concerns exist
Security for smart home products has been uneven and sometimes seriously inadequate. Smart thermostats which can monitor whether a home's occupants are present or not, entry-way locks, and other smart home devices can present very real dangers if hackers can access them.
Matter, emerging standard as of 2023: Secure, reliable, and interoperable
About ten years ago, industry consortiums formed to work on standards for smart home device communications, and their underlying wireless communications, which would make it possible for products from all vendors to work together seamlessly and provide fast performance, privacy, and security and would work even if there is not connection to the outside internet (i.e., no connection to "the cloud" or to servers). This resulted in a new standard, called Matter whose first version was finalized in Sept. 2022 and emerging in the marketplace during 2023. Most major vendors have committed to adhering to the basics of the emerging standard within a few years. Another important, emerging standard for smart home devices is Thread, which specifies how the wireless communications among smart home devices will work when using the Matter standard.
