<h3>OWTHERM</h3>
|
|
<p>FHEM module to commmunicate with 1-Wire bus digital thermometer devices<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>
|
|
<h4>Example</h4>
|
|
<p>
|
|
<code>define OWX_T OWTHERM DS18B20 E8D09B030000 300</code>
|
