Abstract: There are a wide range of smart home products, with rich application scenarios and great imagination, which can bring consumers a beautiful life experience. However, affected by factors such as technology and business model, the interconnection problem of smart home restricts the development of the industry. At present, smart home interconnection is basically based on the two technologies of self-built ecology of head enterprises and cross-brand cloud interconnection. In particular, cross-brand cloud interconnection requires the integration of two or more user account systems. This "centralized" technical architecture solution brings difficulties to brand operation and poor user experience. The essence of smart home interconnection is still to cooperate with each other to complete a certain task in a smart life scenario. Conducting research on broadcast subscription technology, physical model, and technical application, etc., to achieve a minimalist solution for "decentralization" and interconnection between things, and provides a smart home local self-collaboration model based on broadcast subscription technology for local self-collaboration of smart homes, which realizes self-collaboration between smart homes in a minimalist way and improves user experience.
