Session
LoRaWAN gateways typically depend on cloud-based network servers, creating a vulnerability during internet outages. This talk presents a hybrid solution: a Raspberry Pi-based mobile gateway that operates on The Things Stack Sandbox while simultaneously decoding all device messages locally.
The system leverages existing network infrastructure for broad coverage during normal operation, while maintaining full local data access when connectivity fails. This is particularly valuable for emergency response scenarios and remote monitoring where sensor data must remain available regardless of network conditions.
The implementation uses Python for gateway orchestration and API integration, while incorporating existing JavaScript libraries (lora-packet and device decoders) for LoRaWAN decryption and payload decoding. Data is stored locally in SQLite for reliability and easy access.
