Paranode

Paranode

Paranode is a lightweight IoT library for ESP32 and ESP8266 microcontrollers that provides a high-performance WebSocket bridge between hardware and cloud services. Inspired by Blynk, it enables real-time monitoring, telemetry capture, and remote command handling with a focus on production-grade efficiency. The library is heavily optimized for resource-constrained environments, achieving up to 60% less memory usage and 40% faster transmission through advanced C++ templates and custom JSON building. Key features include an offline message queuing system (up to 20 messages), automatic reconnection logic, and a secure heartbeat mechanism for reliable connectivity. By offering a type-safe, template-based API, Paranode empowers developers to build scalable solutions ranging from simple sensor nodes to complex industrial monitoring systems.
