The built-in Data logger is a communication module developed to expand the WiFi wireless network data communication capabilities of non-network-enabled devices. It realizes data communication with devices through UART (TTL level) and accesses the cloud IoT platform through a router, and can support wireless networking and interconnection communication of multiple devices on the edge side.

The module supports functions such as remote data monitoring, remote control, remote upgrade, remote maintenance, edge-side energy management, and local debugging of devices; it provides users with solutions for rapid device connection to the cloud, low cost, and an efficient energy management system.

The main functions supported by the product include: support for Bluetooth seamless network configuration and local connection debugging, support for Wi-Fi internet access, support for the TLS1.2 security protocol, support for Modbus TCP, support for the energy control cloud energy management platform, support for MQTT access to multiple third-party platforms, support for breakpoint OTA, support for European ETSI EN 303 645, support for 2030.5 CSIP-US/AUS, support for dynamic power grids, negative electricity price regulation, and support for device energy interconnection on the edge side.
