Abstract

Third-party smart home platforms raise significant security and privacy concerns due to their centralized hosting models. This study develops a decentralized, easily deployable smart home platform using the FIWARE IoT framework that enables users to host systems on private servers. The platform integrates FIWARE Generic Enablers (Orion, Keyrock, Wilma, IoT Agent) with custom web, mobile, and desktop applications, containerized using Docker Compose. Hardware nodes (NodeMCU ESP8266 with DHT11 sensors and relay modules) operate without a central gateway. The system successfully achieved full CRUD functionality across client applications, with automated Arduino sketch compilation and upload. However, performance testing revealed critical latency anomalies, with the Orion Context Broker exhibiting rare but severe response delays up to 10 seconds. While the platform successfully addresses privacy concerns and simplifies deployment, FIWARE's resource consumption and occasional latency spikes present optimization challenges requiring future work.

Abstract

The development of technology today is very fast and sophisticated. One example of technological developments is the smart home. A smart home is a house or building equipped with high technology that allows various systems and devices in the home to communicate with one another. This technology is very helpful for parents and people with disabilities in activities at home. One way of controlling smart homes currently being developed is voice control. However, some smart home devices do not yet have control features using voice commands in Indonesian. This study aims to create and test a smart home device that can be controlled by voice commands using the Google Speech-to-Text Application Programming Interface (API) as a medium for capturing and converting voice commands from users into text. The results of the conversion are processed using the Cosine Similarity method to determine what commands are given and which devices the user wants to control. This process is carried out on a Single Board Computer (SBC), specifically the Raspberry Pi. The system achieves up to 100% accuracy in quiet conditions with an average response time of 1001.4 ms. However, this accuracy drops to approximately 80% in noisy environments above 65dB, indicating limitations of the Google Speech API under high noise conditions.
