    <h3>Inputs</h3>
    A JSON with these parameters:

    <dl class="message-properties">
        <dt>id
            <span class="property-type">string</span>
        </dt>
        <dd> the nome of the kpi device (you MUST have the ownership of the device)</dd>
		<dt>contextbroker
            <span class="property-type">string</span>
        </dt>
        <dd> the contextbroker of the device</dd>
        <dt>newownership
            <span class="property-type">string</span>
        </dt>
        <dd> the new owner
    </dl>

    <p>An example of the JSON array filled with correct data:</p>
    <pre>
{
"id": "nameDevice",
"contextbroker": "contextbroker",
"newownership": "newOwner"
}
    </pre>

    <h3>Outputs</h3>
    <dl class="message-properties">
        <dd> Returns an object containing the newownership</dd>
    </dl>

    <h3>Details</h3>
    <p>The node can receive a JSON with the parameters described in the Inputs section and with them generate the output JSON.
        If the values are not present in the input JSON, these are read by those in the configuration. If they are not present
        in either part, an error is generated for the necessary parameters.</p>
