uEcho for C, uecho, is a portable and cross platform development framework for creating controller applications and devices of ECHONET Lite. ECHONET is an open standard specification for IoT devices in Japan, it specifies more than 100 IoT devices such as crime prevention sensor, air conditioner and refrigerator.

What is uEcho ?

The uecho supports to control any ECHONET Lite devices or create the standard devices of the specification easily. The uecho is designed in object-oriented programming, and the functions are object-oriented in their naming convention, and are grouped into classes such as Controller, Node, Class and Object.

To implement IoT controller or devices of ECHONET Lite, the developer had to understand and implement the communication middleware specification such as the message format and base sequences.

Using The uecho, all developer has only to set basic listeners to implement the devices and controllers because The uecho handles other requests such as request and notification requests automatically.
