<h3>ZWDongle</h3>
<ul>
  This module serves a ZWave dongle, which is attached via USB or TCP/IP, and
  enables the use of ZWave devices (see also the <a href="#ZWave">ZWave</a>
  module). It was tested wit a Goodway WD6001, but since the protocol is
  standardized, it should work with other devices too. A notable exception is
  the USB device from Merten.
  <br><br>
  <a name="ZWDongledefine"></a>
  <b>Define</b>
  <ul>
    <code>define &lt;name&gt; ZWDongle &lt;device&gt;</code>
  <br>
  <br>
  Upon initial connection the module will get the homeId of the attached
  device. Since the DevIo module is used to open the device, you can also use
  devices connected via  TCP/IP. See <a href="#CULdefine">this</a> paragraph on
  device naming details.
  <br>
  Example:
  <ul>
    <code>define zwdongle_1 ZWDongle /dev/cu.PL2303-000014FA@115200</code><br>
  </ul>
  </ul>
  <br>

  <a name="ZWDongleset"></a>
  <b>Set</b>
  <ul>

  <li>addNode on|onNw|onSec|onNwSec|off<br>
    Activate (or deactivate) inclusion mode. The controller (i.e. the dongle)
    will accept inclusion (i.e. pairing/learning) requests only while in this
    mode. After activating inclusion mode usually you have to press a switch
    three times within 1.5 seconds on the node to be included into the network
    of the controller. If autocreate is active, a fhem device will be created
    after inclusion. "on" activates standard inclusion. "onNw" activates network
    wide inclusion (only SDK 4.5-4.9, SDK 6.x and above).<br>
    If onSec/onNwSec is specified, the ZWDongle networkKey ist set, and the
    device supports the SECURITY class, then a secure inclusion is attempted.
    </li>

  <li>backupCreate 16k|32k|64k|128k|256k<br>
    read out the NVRAM of the ZWDongle, and store it in a file called
    &lt;ZWDongle_Name&gt;.bin in the modpath folder.  Since the size of the
    NVRAM is currently unknown to FHEM, you have to specify the size. The
    ZWave.me ZME_UZB1 Stick seems to have 256k of NVRAM. Note: writing the file
    takes some time, usually about 10s for each 64k (and significantly longer
    on Windows), and FHEM is blocked during this time.
    </li>

  <li>backupRestore<br>
    Restore the file created by backupCreate. Restoring the file takes about
    the same time as saving it, and FHEM is blocked during this time.
    Note / Important: this function is not yet tested for older devices using
    the MEMORY functions.
    </li>

  <li>clearStatistics<br>
    clear network statistics.
    </li>

  <li>controllerChange on|stop|stopFailed<br>
    Add a controller to the current network and transfer role as primary to it.
    Invoking controller is converted to secondary.<br>
    stop: stop controllerChange<br>
    stopFailed: stop controllerChange and report an error
    </li>

  <li>createNewPrimary on|stop|stopFailed<br>
    Add a controller to the current network as a replacement for an old
    primary. Command can be invoked only by a secondary configured as basic
    SUC<br>
    stop: stop createNewPrimary<br>
    stopFailed: stop createNewPrimary and report an error
    </li>

  <li>createNode &lt;device&gt;<br>
      createNodeSec &lt;device&gt;<br>
    Request the class information for the specified node, and create
    a FHEM device upon reception of the answer. Used to create FHEM devices for
    nodes included with another software or if the fhem.cfg got lost. For the
    node id see the get nodeList command below.  Note: the node must be "alive",
    i.e. for battery based devices you have to press the "wakeup" button 1-2
    seconds before entering this command in FHEM.<br>
    &lt;device&gt; is either device name or decimal nodeId.<br>
    createNodeSec assumes a secure inclusion, see the comments for "addNode
    onSec" for details.
    </li>

  <li>factoryReset yes<br>
    Reset controller to default state.
    Erase all node and routing infos, assign a new random homeId.
    To control a device it must be re-included and re-configured.<br>
    !Use this with care AND only if You know what You do!<br>
    Note: the corresponding FHEM devices have to be deleted manually.
    </li>

  <li>learnMode on|onNw|disable<br>
    Add or remove controller to/from an other network.
    Assign a homeId, nodeId and receive/store nodeList and routing infos.
    </li>

  <li>removeFailedNode &lt;device&gt;<br>
    Remove non-responding node -that must be on the failed node list-
    from the routing table in controller. Instead, always use removeNode if
    possible. Note: the corresponding FHEM device have to be deleted 
    manually.<br>
    &lt;device&gt; is either device name or decimal nodeId.
    </li>

  <li>removeNode onNw|on|off<br>
    Activate (or deactivate) exclusion mode. "on" activates standard exclusion.
    "onNw" activates network wide exclusion (only SDK 4.5-4.9, SDK 6.x and
    above).  Note: the corresponding FHEM device have to be deleted
    manually.
    </li>

  <li>reopen<br>
    First close and then open the device. Used for debugging purposes.
    </li>

  <li>replaceFailedNode &lt;device&gt;<br>
    Replace a non-responding node with a new one. The non-responding node
    must be on the failed node list.<br>
    &lt;device&gt; is either device name or decimal nodeId.
    </li>

  <li>routeFor &lt;device&gt; &lt;hop1&gt; &lt;hop2&gt; &lt;hop3&gt;
               &lt;hop4&gt; &lt;speed&gt;<br>
    set priority routing for &lt;device&gt;. &lt;device&gt; and &lt;hopN&gt are
    either device name or decimal nodeId or 0 for unused.<br>
    &lt;speed&gt;: 1=9,6kbps; 2=40kbps; 3=100kbps
    </li>

  <li>sendNIF &lt;device&gt;<br>
    Send NIF to the specified &lt;device&gt;.
    &lt;device&gt; is either device name or decimal nodeId.
    </li>

  <li>sucNodeId &lt;decimal nodeId&gt; &lt;sucState&gt;
                &lt;capabilities&gt;<br>
    Configure a controller node to be a SUC/SIS or not.<br>
    &lt;nodeId&gt;: decimal nodeId to be SUC/SIS<br>
    &lt;sucState&gt;: 0 = deactivate; 1 = activate<br>
    &lt;capabilities&gt;: 0 = basic SUC; 1 = SIS
    </li>

  <li>sucRequestUpdate &lt;decimal nodeId of SUC/SIS&gt;<br>
    Request network updates from SUC/SIS. Primary do not need it.
    </li>

  <li>sucSendNodeId &lt;decimal nodeId&gt;<br>
    Send SUC/SIS nodeId to the specified decimal controller nodeId.

    <li><a name="neighborListFmt">neighborListFmt</a><br>
      Used by the "Show neighbor map" function in the FHEMWEB ZWDongle detail
      screen. The value is a perl hash, specifiying the values for the keys
      txt, img and title. In the value each word is replaced by the
      corresponding Internal, Reading or Attribute of the device, if there is
      one to replace. Default is
      <ul><code>
        { txt=>"NAME", img=>"IMAGE", title=>"Time to ack: timeToAck" }
      </code></ul>
      </li>
    <li><a name="showSetInState">showSetInState</a><br>
      If the attribute is set to 1, and a user issues a set command to a ZWave
      device, then the state of the ZWave device will be changed to
      set_&lt;cmd&gt; first, and after the ACK from the device is received, to
      &lt;cmd&gt;. E.g.: Issuing the command on changes the state first to
      set_on, and after the device ack is received, to on.  This is analoguos
      to the CUL_HM module.  Default for this attribute is 0.
