eze System develops and sells cloud-based solutions and controllers that can remotely measure, log and control anything that can be monitored with a sensor. The ezeio is designed to be easy to set up. There is no software to install, and in most cases it works right out of the box after being plugged in with no setup what so ever. The controller (and a connected sensor) is the only component you need for a working system. There are four models of the controller, having different connectivity options. All models have Ethernet connectivity, Modbus, Microlan, four analog and two relays. All models use the same configuration system and all can be expanded up to 40 inputs and 40 outputs.
