From the developer:
Swintechnics Device Finder shows a real-time list of Swintechnics devices (e.g., mIoTa) available on your local area network, and gives detailed information about each device. The web site (if available) for each device can be accessed easily by pressing the 'OPEN' button for that device. The detailed technical information about a particular device can be shown by pressing the 'i' button.
