Integration and Cost Optimization of Lightweight IoT Technology in the Renovation of Small and Medium-Sized Apartments

The rapid development of the Internet of Things (IoT) has brought challenges to the digital transformation of small and medium-sized apartment (SMA) enterprises, such as high costs and high technical barriers for IoT transformation. This paper proposes a lightweight IoT solution suitable for apartments with a scale of 100 to 500 units, aiming to reduce the transformation threshold and achieve energy saving and cost reduction. The research focuses on the selection criteria and integration methods of low-cost intelligent sensors (such as hundred-yuan level smart locks and energy consumption monitoring modules), and through the practical case of lightweight transformation of the “Dynamic Energy Consumption Monitoring System”, the feasibility of controlling the transformation cost of a single apartment within 300 yuan is verified. This paper not only elaborates on the integration application of lightweight IoT technology in the renovation of small and medium-sized apartments, but also provides a technical path and data support for small and medium-sized apartment enterprises through cost optimization strategies and benefit analysis, offering references for the digital transformation of the industry.
