The VERVE2 is designed to be used with a host computer. It receives its power from the host's USB. Keyboard and mouse emulation allow it to be connected to any computer that accepts USB keyboard/mouse input. However, for data logging, triggering internet actions, or web-based data serving, the VERVE2 unit must be used with a Mac or Windows computer that is running the Verve App (included with the VERVE2). The VERVE App makes it easy to see that is going on with the sensors, easy to record the sensor data, and easy to serve the data as a web server. In addition, the VERVE App can do these things while running in the background. The VERVE2 unit itself is not a web server and cannot work as a standalone device.
