The advancement in the internet of things (IoT) technologies has made it possible to control and monitor electronic devices at home with just the touch of a button. This has made people lead much more comfortable lifestyles. Elderly people and those with disabilities have especially benefited from voice-assisted home automation systems that allow them to control their devices with simple voice commands. However, the widespread use of cloud-based services in these systems, such as those offered by Google and Amazon, has made them vulnerable to cyber-attacks. To ensure the proper functioning of these systems, a stable internet connection and a secure environment free from cyber-attacks are required. However, the quality of the internet is often low in developing countries, which makes it difficult to access the services these systems offer. Additionally, the lack of localization in voice assistants prevents people from using voice-assisted home automation systems in these countries. To address these challenges, this research proposes an offline home automation system. Since the internet and cloud services are not required for an offline system, it can perform its essential functions, while ensuring protection against cyber-attacks and can provide quick responses. It offers additional features, such as power usage tracking and the optimization of linked devices.
物联网 (IoT) 技术的进步使得人们只需轻触按钮即可控制和监控家庭中的电子设备。这使人们的生活更加舒适。老年人和残疾人特别受益于语音辅助家庭自动化系统，使他们可以通过简单的语音命令控制设备。然而，这些系统中广泛使用的基于云的服务（如谷歌和亚马逊提供的服务）使它们容易受到网络攻击。为了确保这些系统的正常运行，需要稳定的互联网连接和没有网络攻击的安全环境。然而，发展中国家的互联网质量往往较低，这使得人们难以访问这些系统提供的服务。此外，语音助手缺乏本地化，使得这些国家的人们无法使用语音辅助家庭自动化系统。为了解决这些挑战，本研究提出了一种离线家庭自动化系统。由于离线系统不需要互联网和云服务，因此它可以执行其基本功能，同时确保免受网络攻击，并能够提供快速响应。它还提供了额外的功能，例如用电跟踪和链接设备的优化。
