<h3>Hunter Hydrawise</h3>
<ul>
  The module receives data and sends commands via the Hunter Hydrawise API.<br>
  All zones are identified by a unique ID - this ID is used to modify zone watering schedules,
  including running a zone, stopping a zone and suspending a zone for a period of time.
  Status information on all zones associated with an account can also be queried.
  <br>

  <br>
  <b>Prerequisits</b>
  <ul>
    <br/>
    API keys can be obtained from your Hydrawise account under My Account -> Generate API Key.
    This has the format XXXX-XXXX-XXXX-XXXX.

<h3>Hunter Hydrawise</h3>
<ul>
  Das Modul empf&auml;ngt Daten und sendet Befehle &uuml;ber die Hunter Hydrawise API.<br>
  Alle Zonen werden durch eine eindeutige ID identifiziert - diese ID wird verwendet, um die Bew&auml;sserungspl&auml;ne der Zonen zu modifizieren,
  einschlie&szlig;lich des Betreibens einer Zone, des Anhaltens einer Zone und des Aussetzens einer Zone f&uuml;r eine bestimmte Zeit.
  Statusinformationen zu allen Zonen, die mit einem Konto verbunden sind, k&ouml;nnen ebenfalls abgefragt werden.
  <br>
  <br>
  <b>Voraussetzungen</b>
  <ul>
    <br/>
    Einen API-Schl&uuml;ssel k&ouml;nnen Sie von Ihrem Hydrawise-Konto unter Mein Konto generieren lassen.
    Dieser hat das Format XXXX-XXXX-XXXX-XXXX.
