Wireless communication systems based on discharge‐induced displacement current exhibit significant potential for enhancing the convenience, security, and low power consumption of wireless systems. However, their practical applications remain largely constrained by the complexity of signals in both the time and frequency domains. Here, a novel compact wireless passive system composed of a self‐powered wireless e‐sticker (SWES) and electronic circuits, enabling long‐distance wireless communication through a real‐time signal processing strategy, thereby applicable in smart homes is proposed. The SWES seamlessly integrates a triboelectric nanogenerator with an optimized plasma switch to ensure stable wireless signal transmission under mechanical stimulation, achieving a transmission distance as high as 13 m, while maintaining a lightweight of 0.24 g and a compact size of 3.5 × 2.5 × 0.0167 cm3. Furthermore, a multimodal smart home control system that integrates this wireless passive design with a dedicated control application, enabling monitoring of the appliance status and intelligent control, thereby validating the system's convenience, security, and versatility is demonstrated. The proposed system is poised for widespread deployment in smart homes, facilitating wireless intelligent control of various electronic appliances powered by municipal electricity and holding substantial potential for applications in smart cities, wearable electronics, and human–machine interfaces.
