While there are many competing vendors, there are increasing efforts towards open source systems. However, there are issues with the current state of home automation including a lack of standardized security measures and deprecation of older devices without backwards compatibility.
Home automation has high potential for sharing data between family members or trusted individuals for personal security and could lead to energy saving measures with a positive environmental impact in the future.
The home automation market was worth US$64 billion in 2022 and is projected to grow to over $163 billion in 2028.

found that home automation could involve high cost of ownership, inflexibility of interconnected devices, and poor manageability.
When designing and creating a home automation system, engineers take into account several factors including scalability, how well the devices can be monitored and controlled, ease of installation and use for the consumer, affordability, speed, security, and ability to diagnose issues. Findings from iControl showed that consumers prioritize ease-of-use over technical innovation, and although consumers recognize that new connected devices have an unparalleled cool factor, they are not quite ready to use them in their own homes yet.
Historically, systems have been sold as complete systems where the consumer relies on one vendor for the entire system including the hardware, the communications protocol, the central hub, and the user interface. However, there are now

systems which can be used instead of or with proprietary hardware.
Many of these systems interface with consumer electronics such as the Arduino or Raspberry Pi, which are easily accessible online and in most electronics stores. In addition, home automation devices are increasingly interfaced with mobile phones through Bluetooth, allowing for increased affordability and customizability for the user.

, since patches to bugs found in the core operating system often do not reach users of older and lower-price devices.
One set of researchers say that the failure of vendors to support older devices with patches and updates leaves more than 87% of active devices vulnerable.
Concerns have been raised by tenants renting from landlords who decide to upgrade units with smart home technology. These concerns include weak wireless connections that render the door or appliance unusable or impractical; the security of door passcodes kept by the landlord; and the potential invasion of privacy that comes with connecting smart home technologies to home networks.
Researchers have also conducted user studies to determine what the barriers are for consumers when integrating home automation devices or systems into their daily lifestyle. One of the main takeaways was regarding ease of use, as consumers tend to steer towards "plug and play" solutions over more complicated setups.
One study found that there were large gaps in the mental-models generated by users regarding how the devices actually work.
Specifically, the findings showed that there was a lot of misunderstanding related to where the data collected by smart devices was stored and how it was used.
For example, in a smart light setup, one participant thought that her iPad communicated directly with the light, telling it to either turn off or on.
In reality, the iPad sends a signal to the cloud system that the company uses (in this case, the Hue Bridge) which then signals directly to the device.
Overall, this field is still evolving and the nature of each device is constantly changing. While technologists work to create more secure, streamlined, and standardized security protocols, consumers also need to learn more about how these devices work and what the implications of putting them in their homes can be. The growth of this field is currently limited not only by the technology but also by a user's ability to trust a device and integrate it successfully into his/her daily life.
Impact
Utilizing home automation could lead to more efficient and intelligent energy saving techniques.
By integrating information and communication technologies (ICT) with renewable energy systems such as solar power or wind power, homes can autonomously make decisions about whether to store energy or expend it for a given appliance,
leading to overall positive environmental impacts and lower electricity bills for the consumers using the system. In order to do this, researchers propose using data from sensors regarding consumer activity within the home to anticipate the consumer needs and balance that with energy consumption.
Furthermore, home automation has large potential regarding family safety and security. According to a 2015 survey done by iControl, the primary drivers of the demand for smart and connected devices are first "personal and family security", and second "excitement about energy savings".
Home automation includes a variety of smart security systems and surveillance setups. This allows consumers to monitor their homes while away, and to give trusted family members access to that information in case anything bad happens.
