The deep integration of building and home furnishing design and Internet of Things technology creates a comfortable, energy-saving and safe working and living environment for people. This paper designs an application scenario of Internet of Things in intelligent building home design, integrates intelligent building home, Internet of Things and other technologies, designs the overall architecture of the system, and realizes the intelligent door control and temperature control system of building home relying on the simulation platform. After testing, the overall operation of the system is stable, thus providing a solution for the application of the Internet of Things in intelligent building home.
