Development of an Open Smart Home Controller

This paper describes the development of an electricity visualization tool that can be used on multiple platforms without requiring new contracts or complex installation work. Existing services that provide electricity visualization require different arrangements and installation work for each company, making their introduction complicated and costly. The tool is packaged as a multi-platform system that can be used on Windows, Linux, and MacOS, making it widely available. A questionnaire survey was conducted to confirm the usability of the developed visualization screen, and 80% of the participants expressed a desire to introduce the system.
