<h3>OWAD</h3>
|
|
<ul>
|
|
<p>FHEM module to commmunicate with 1-Wire A/D converters<br /><br />
|
|
<br />This 1-Wire module works with the OWX interface module or with the OWServer interface module
|
|
(prerequisite: Add this module's name to the list of clients in OWServer).
|
|
Please define an <a href="#OWX">OWX</a> device or <a href="#OWServer">OWServer</a> device first. <br/></p>
|
|
<br /><h4>Example</h4>
|
|
<p>
|
|
<code>define OWX_AD OWAD 724610000000 45</code>
|
|
<br />
|
|
<code>attr OWX_AD DAlarm high</code>
|
|
<br />
|
|
<code>attr OWX_AD DName humidity</code>
|
|
<br />
|
|
<code>attr OWX_AD DUnit %</code>
|
|
<br />
|
|
<code>attr OWX_AD DFunction VD*31.907097-0.8088</code>

<h4>Define</h4>
|
|
<p>
|
|
<code>define <name> OWAD [<model>] <id> [<interval>]</code> or <br/>
|
|
<code>define <name> OWAD <fam>.<id> [<interval>]</code>
|
|
<br /><br /> Define a 1-Wire A/D converter.<br /><br /></p>
|
|
<ul>
|
|
<li>
|
|
<code>[<model>]</code><br /> Defines the A/D converter model (and thus 1-Wire
|
|
family id), currently the following values are permitted: <ul>
|
|
<li>model DS2450 with family id 20 (default if the model parameter is
|
|
omitted)</li>
|
|
</ul>
|
|
</li>
|
|
<li>
|
|
<code><fam></code>
|
|
<br />2-character unique family id, see above
|
|
</li>
|
|
<li>
|
|
<code><id></code>
|
|
<br />12-character unique ROM id of the converter device without family id and CRC
|
|
code </li>
|
|
<li>
|
|
<code><interval></code>
|
|
<br />Measurement interval in seconds. The default is 300 seconds, a value of 0 disables the automatic update. </li>
