How to implement a new plugin

• Create a thing type XXXThing (See Thing types)
• Create the observations type the thing XXXThing produces or consumes, example XXXThingObserv1 (See Observations and observation types)
• Associate the observation XXXThingObserv1 type to the XXXThing
• Implement a nodejs module with the following interface

    function XXXThing() {
    }

    XXXThing.prototype.start = function ( complete) {
        try {
            complete(null);
        } catch (e) {
            complete(e);
        }
    };

    XXXThing.prototype.stop = function (complete) {
        try {
            complete(null);
        } catch (e) {
            complete(e);
        }
    };

    XXXThing.prototype.command = function (observation, complete) {
        try {
            complete(null);
        } catch (e) {
            complete(e);
        }
    };

    module.exports.XXXThing = XXXThing;
