    <p> Node for transmission of KNX write requests to the configured group address. </p>

    <h3>Properties</h3>
        <dl class="message-properties">
            <dt>Gateway</dt>
            <dd> Selected KNX gateway. </dd>

            <dt>Group Address
                <span class="property-type">x/y/z</span>
            </dt>
            <dd> KNX group address to write. </dd>

            <dt>Datapoint</dt>
            <dd> KNX datapoint type (DPT). </dd>

            <dt>Output Type</dt>
            <dd> Choose if this output should be a write or respond event </dd>
        </dl>

    <h3>Inputs</h3>
        <dl class="message-properties">
            <dt>payload</dt>
            <dd>Value to transmit</dd>
            <dt>knx</dt>
            <dd> <p>The following parameters can be sent to override what is configured for the node: 
                <pre>
{ "knx": { 
    "event": "GroupValue_Write",
     "dpt":"1.001",
     "destination": "1/1/1"
    }
}                   </pre>
                    (DPTs can be sent as 9 , "9" , "9.001" or "DPT9.001")</p>
                    <p>Example: 
                        If you only want to override destination you would send only that, eventType and dpt will be taken from node config:
                    <pre>
{ "knx": { 
     "destination": "1/1/1"
    }
}                   </pre>
                    </p>
            </dd>
        </dl>

    <h3>Details</h3>
        <p>
            Based on configured DPT the <code>msg.payload</code> is automatically converted into the KNX on-wire
            representation before transmission.
        </p>

        <h4>Example for DPT 10.001 (TimeOfDay)</h4>
        <p>
            The <code>msg.payload</code> with a logical time value <code>"07:15:32"</code> will be transmitted as
            KNX telegram of type <code>GroupValue_Write</code> with the 3 payload bytes <code>0x07 0x0F 0x20</code>.
        </p>
