The advent of smart metering technologies has revolutionized water consumption monitoring, enabling more precise and real-time data collection. This thesis explores the implementation of a private LoRaWAN network to manage and monitor sensor data, with a focus on handling an additional encryption layer in data transmission. The primary research question addressed is:How can a secure and efficient private LoRaWAN network be deployed to manage sensor data with additional encryption layers, and how can this data be effectively visualized?To address this question, a comprehensive methodology was employed, which included setting up a LoRaWAN network server using ChirpStack, deploying sensors with additional encryption, and designing a secure system to handle data decryption and storage. A Flask application was developed to receive and decrypt sensor data, store it in InfluxDB, and visualize it using Grafana.The data decryption was managed by implementing a custom AES decryption algorithm that utilized specific device keys and initialization vectors.The results demonstrated that the implemented system could successfully decrypt, store, and visualize sensor data in real-time underscoring the potential for advanced metering infrastructure to contribute to more efficient and sustainable water resource management.
