Rhea is a software tool designed to manage and exercise Numato Lab’s GPIO and Relay modules. Rhea supports most GPIO/Relay devices manufactured by Numato Lab with USB, Ethernet, or WiFi interface. This software tool offers an out-of-the-box experience when working with Numato Lab’s GPIO and Relay Modules. While the powerful command-line-like interface provided by these devices offer very quick and easy setup and use by taking advantage existing software such as TeraTerm, PuTTY, HyperTerminal or your own custom script/program, Rhea goes one step further by offering a full-fledged GUI that looks great and works out of the box. Rhea makes it easier to use Numato Lab’s GPIO/Relay Modules without needing to learn the commands or other specifics and can be used for basic automation and other tasks.
