This thesis addresses the field of modern smart home systems and their integration with energy harvesting technologies. The objective of the work is the design and implementa- tion of an autonomous smart component that operates without battery power, instead utilizing energy obtained from its surroundings. The theoretical section introduces current smart home platforms and communication technologies, with particular focus on the Matter standard, which represents the current trend in smart devices. Subsequently, the field of energy harvesting is analyzed as a sus- tainable alternative to traditional power sources, including an overview of the physical principles of obtaining energy from ambient sources. The practical part of the thesis is based on market research, which revealed a lack of commercially available solutions combining battery-less operation with native Matter support. Based on the established requirements, a custom device was designed, di- vided into two logical units: an energy-efficient end node and a communication gateway (Matter bridge). The thesis covers the design and implementation of both parts of the system in detail. TheendnodeisbasedonBluetoothLowEnergytechnologyandthenRF52832platform. It was developed in two hardware iterations designed in KiCad, commissioned and tested on real hardware. Due to the excessive power consumption of the original SoftDevice stack during initialization, a custom lightweight BLE stack was implemented for the end node. The Matter bridge translates BLE packets into the Matter ecosystem using two ESP32-S3 microcontrollers enabling simultaneous BLE and Wi-Fi operation. The bridge firmware was developed using ESP-IDF. Measurements confirmed that a single mechanical press harvests 95–112𝜇J of energy with a utilization efficiency of 69–74%. End-to-end transmission reliability exceeds 98.8% at a 95% confidence level, with a latency of 558ms. The result is a func- tional prototype demonstrating that battery-less operation with native Matter support is technically feasible.
