\title OSDomotics
\brief Plugin for the OSDomotics Merkur board based on the OSDomotics tutorials.
\ingroup plugins
\ingroup nymea-plugins-merkur
This plugin allows you to connect nymea to a 6LoWPAN network by adding a Mercury Board from OSDomotics
as a RPL router to your devices \l{http://osdwiki.open-entry.com/doku.php/de:tutorials:contiki:merkur_board_rpl_usb_router}{OSDomotics Tutorial- RPL Router}.
All nodes in the 6LoWPAN network of the added RPL router will appear automatically in the system.
\note Currently the plugin recognizes only one node. That node has to be flashed like the Node in this \l{http://osdwiki.open-entry.com/doku.php/de:tutorials:contiki:use_example_firmware}{OSDomotics Tutorial - Firmware}.
\chapter Plugin properties
Following JSON file contains the definition and the description of all available \l{ThingClass}{DeviceClasses}
and \l{Vendor}{Vendors} of this \l{DevicePlugin}.
For more details how to read this JSON file please check out the documentation for \l{The plugin JSON File}.
