A middleware that is installed on a range of gateways and connects equipment to InfiIoT and popular Internet of Things(IoT) or Industrial Internet of Things (IIoT) clouds. It securely connects various devices (e.g., PV panels, battery energy storage, HVACs, EV stations, compressors, and boilers) through industrial protocols (Modbus, OPC UA, BACnet) and cellular networks (LTE and 5G). InfiConnector is configurable from cloud services to collect data from devices and sensors and prepare data for data analysis and Artificial Intelligence (AI) cloud applications. InfiConnector provides a code-less edge computing and rule engine interface that configures any machine to machine, diagnostic, alerting, and log management services in a few minutes. The light middleware requires 512MB RAM, 1 core CPU, and 16GB disk. It is compatible with Ubuntu 20.04 and upper.
