    <h3>
      msgConfig
    </h3>
    <ul>
      Provides global settings and tools for FHEM command <a href="#MSG">msg</a>.<br>
      A device named globalMsg will be created automatically when using msg-command for the first time and no msgConfig device could be found.<br>
      The device name can be renamed and reconfigured afterwards if desired.<br>
      <br>
      <a name="msgConfigdefine" id="msgConfigdefine"></a> <b>Define</b>
      <ul>
        <code>define &lt;name&gt; msgConfig</code><br>

      <ul>
        <ul>
          <li>
            <b>addLocation</b> &nbsp;&nbsp;<Location Name>&nbsp;&nbsp;<br>
            Conveniently creates a Dummy device based on the given location name. It will be pre-configured to be used together with location-based routing when using the msg-command. The dummy device will be added to attribute msgLocationDevs automatically. Afterwards additional configuration is required by adding msgContact* or msgRecipient* attributes for gateway devices placed at this specific location.
          </li>
          <li>
            <b>cleanReadings</b> &nbsp;&nbsp;[<device and/or regex>]&nbsp;&nbsp;<br>
            Easy way to cleanup all fhemMsg readings. A parameter is optional and can be a concrete device name or mixed together with regex. This command is an alias for "deletereading <device and/or regex> fhemMsg.*".
          </li>
          <li>
            <b>createResidentsDev</b> &nbsp;&nbsp;<de|en>&nbsp;&nbsp;<br>
            Creates a new device named rgr_Residents of type <a href="#RESIDENTS">RESIDENTS</a>. It will be pre-configured based on the given language. In case rgr_Residents exists it will be updated based on the given language (basically only a language change). Afterwards next configuration steps will be displayed to use RESIDENTS together with presence-based routing of the msg-command.<br>
This next step is basically to set attribute msgResidentsDevice to refer to this RESIDENTS device either globally or for any other specific FHEM device (most likely you do NOT want to have this attribute set globally as otherwise this will affect ALL devices and therefore ALL msg-commands in your automations).<br>
            Note that use of RESIDENTS only makes sense together with ROOMMATE and or GUEST devices which still need to be created manually. See <a href="#RESIDENTSset">RESIDENTS Set commands</a> addRoommate and addGuest respectively.
          </li>
          <li>
            <b>createSwitcherDev</b> &nbsp;&nbsp;<de|en>&nbsp;&nbsp;<br>
            Creates a pre-configured Dummy device named HouseAnn and updates globalMsg attribute msgSwitcherDev to refer to it.

            Erstellt auf einfache Weise ein Dummy Device basierend auf dem &uuml;bergebenen Lokationsnamen. Es wird for die lokations-basierte Verwendung mit dem msg-Kommando vorkonfiguriert. Das Dummy Device wird automatisch zum Attribut msgLocationDevs hinzugef&uuml;gt. Anschlie&szlig;end ist eine weitere Konfiguration &uuml;ber die Attribute msgContact* oder msgRecipient* notwendig, die auf entsprechende Gateway Devices verweisen, die an dieser Lokation stehen.
