It provides the core identity of an IoT device management tool, enabling the synchronization of device states, remote hardware control, and the mapping of hardware data to cloud-based interfaces. The project distinguishes itself through a virtual-pin system that decouples cloud communication from physical pins, allowing for hardware-independent data exchange. It also supports advanced architectural offloading, where network communication can be delegated to a dedicated co-processor to support non-connected microcontrollers. The library covers a broad range of capabilities, including automated device provisioning, over-the-air firmware updates, and a multi-tenant organizational structure for fleet management. It integrates various communication protocols such as MQTT and HTTPS, and provides tools for logic-based automation, time-series data storage, and the construction of mobile and web dashboards for real-time monitoring. The project is implemented in C++. ## Tags ### Hardware & IoT - [Cloud IoT Connectivity](https://awesome-repositories.com/f/hardware-iot/connectivity-iot/cloud-iot-connectivity.md) — Establishes low-latency, bi-directional streaming connections between microcontrollers and a remote cloud server.
