<h3>KS300</h3>
<ul>
Fhem can receive the KS300 or KS555 radio messages through the <a
href="#FHZ">FHZ</a>, <a href="WS300">WS300</a> or <a href="#CUL">CUL</a>, so
one of them must be defined first.<br> This module services messages received
by the FHZ or CUL.<br> <br>
<a name="KS300define"></a>
<b>Define</b>
<ul>
<code>define &lt;name&gt; KS300 &lt;housecode&gt; [ml/raincounter [wind-factor]]</code>
<br><br>
<code>&lt;housecode&gt;</code> is a four digit hex number, it must be
specified foir historic reasons, and it is ignored.
The ml/raincounter defaults to 255 ml, and it must be specified if you wish
to set the wind factor, which defaults to 1.0. <br>
Examples:
<ul>
<code>define ks1 KS300 1234</code><br>
</ul>
</ul>

<li>strangeTempDiff DIFFVAL<br>
If set, the module will only accept temperature values when the
difference between the reported temperature and the last recorded value
is less than DIFFVAL.</li>
<li>rainadjustment<br>
If this attribute is set, fhem automatically considers rain counter
resets after a battery change and random counter switches as
experienced by some users. Default is 0 (off).</li>

<h3>KS300</h3>
<ul>
Fhem kann KS300 bzw. KS555 Funktelegramme mit einem <a href="#FHZ">FHZ</a>,
einem <a href="WS300">WS300</a> oder einem <a href="#CUL">CUL</a> empfangen.
Daher muss eines von diesen zuerst definiert sein.<br> Dieses Modul behandelt
Nachrichten die mittels CUL oder FHZ empfangen werden.<br>
<br>
<a name="KS300define"></a>
<b>Define</b>
<ul>
<code>define &lt;name&gt; KS300 &lt;housecode&gt; [ml/raincounter [wind-factor]]</code>
<br><br>
<code>&lt;housecode&gt;</code> ist ein vierstelliger HEX-Wert, der aus
historischen Gr&uuml;nden angegeben werden muss, es wird ignoriert. Der
ml/raincounter hat einen Default-Wert von 255ml, und muss angegeben sein
wenn man den Wind-Faktor setzen will. Dieser hat einen Default-Wert von
1.0.<br>
Beispiele:
<ul>
<code>define ks1 KS300 1234</code><br>

<li>rainadjustment<br>
Wenn dieses Attribut gesetzt ist, Regenmesser resets werden automatisch
ber&uuml;cksichtigt. Resets treten beim Wechsel der Batterie und nach
Beobachtung einiger Benutzer auch nach zuf&auml;lligen Schaltzyklen
auf. Die Voreinstellung ist 0 (aus).</li>
<li>strangeTempDiff DIFFVAL<br>
Falls gesetzt, werden nur solche Temperaturen akzeptiert, wo der
Unterschied bei der gemeldeten Temperatur zum letzten Wert weniger als
DIFFVAL ist. </li>
