<h3>Wether Sensors protocol #7</h3>
|

<ul>
|

The SD_WS07 module interprets temperature sensor messages received by a Device like CUL, CUN, SIGNALduino etc.<br>
|

<b>Known models:</b>

<li>Eurochon EAS800z</li>

<li>Technoline WS6750/TX70DTH</li>

New received device are add in fhem with autocreate.

|
|
<ul>The received devices created automatically.<br>
|
|
The ID of the defice is the cannel or, if the longid attribute is specified, it is a combination of channel and some random generated bits at powering the sensor and the channel.<br>
|
|
If you want to use more sensors, than channels available, you can use the longid option to differentiate them.

<h3>SD_WS07</h3>

Das SD_WS07 Module verarbeitet von einem IO Geraet (CUL, CUN, SIGNALDuino, etc.) empfangene Nachrichten von Temperatur-Sensoren.<br>

|
|
<b>Unterstuetze Modelle:</b>

Neu empfangene Sensoren werden in FHEM per autocreate angelegt.

Die ID der angelgten Sensoren ist entweder der Kanal des Sensors, oder wenn das Attribut longid gesetzt ist, dann wird die ID aus dem Kanal und einer Reihe von Bits erzeugt, welche der Sensor beim Einschalten zufaellig vergibt.<br>
