<h3>Xiaomi Flower Monitor</h3>
<ul>
  <u><b>XiaomiFlowerSens - liest Daten von einem Xiaomi Flower Monitor</b></u>
  <br />
  Dieser Modul liest Daten von einem Sensor und legt sie in den Readings ab.<br />
  Auf dem (Linux) FHEM-Server werden gatttool und hcitool vorausgesetzt. (sudo apt install bluez)
  <br /><br />
  <a name="XiaomiFlowerSensdefine"></a>
  <b>Define</b>
  <ul><br />
    <code>define &lt;name&gt; XiaomiFlowerSens &lt;BT-MAC&gt;</code>
    <br /><br />
    Beispiel:
    <ul><br />
      <code>define Weihnachtskaktus XiaomiFlowerSens C4:7C:8D:62:42:6F</code><br />
    </ul>
    <br />
	Der Befehl legt ein Device vom Typ XiaomiFlowerSens an mit dem Namen Weihnachtskaktus und der Bluetooth MAC C4:7C:8D:62:42:6F.<br />
	Nach dem Anlegen des Device werden umgehend und automatisch die aktuellen Daten vom betroffenen Xiaomi Flower Monitor gelesen.
