=begin html
<a id="MQTT_DEVICE"></a>
<h3>MQTT_DEVICE</h3>
<ul>
<p>acts as a fhem-device that is mapped to <a href="http://mqtt.org/">mqtt</a>-topics.</p>
<p>requires a <a href="#MQTT">MQTT</a>-device as IODev<br/>
Note: this module is based on <a href="https://metacpan.org/pod/distribution/Net-MQTT/lib/Net/MQTT.pod">Net::MQTT</a> which needs to be installed from CPAN first.</p>
<a id="MQTT_DEVICE-define"></a>
<p><b>Define</b></p>
<ul>
<p><code>define &lt;name&gt; MQTT_DEVICE</code><br/>
Specifies the MQTT device.</p>
</ul>
<a id="MQTT_DEVICE-set"></a>
<p><b>Set</b></p>
<ul>
<li>
<p><code>set &lt;name&gt; &lt;command&gt;</code><br/>
sets reading 'state' and publishes the command to topic configured via attr publishSet</p>
</li>
<li>
<p><code>set &lt;name&gt; &lt;reading&gt; &lt;value&gt;</code><br/>
sets reading &lt;reading&gt; and publishes the command to topic configured via attr publishSet_&lt;reading&gt;</p>
</li>
<li>
<p>The <a href="#setExtensions">set extensions</a> are supported with useSetExtensions attribute.<br/>
Set eventMap if your publishSet commands are not on/off.</p>
<p>example for true/false:<br/>
<code>attr mqttest eventMap { dev=>{ 'true'=>'on', 'false'=>'off' }, usr=>{ '^on$'=>'true', '^off$'=>'false' }, fw=>{ '^on$'=>'on', '^off$'=>'off' } }</code></p>
</li>
</ul>
<a id="MQTT_DEVICE-attr"></a>
<p><b>Attributes</b></p>
<ul>
<li>
<p><code>attr &lt;name&gt; publishSet [[&lt;reading&gt;:]&lt;commands_or_options&gt;] &lt;topic&gt;</code><br/>
configures set commands and UI-options e.g. 'slider' that may be used to both set given reading ('state' if not defined) and publish to configured topic</p>
<p>example:<br/>
<code>attr mqttest publishSet on off switch:on,off level:slider,0,1,100 /topic/123</code>
</p>
</li>
<li>
<p><code>attr &lt;name&gt; publishSet_&lt;reading&gt; [&lt;values&gt;]* &lt;topic&gt;</code><br/>
configures reading that may be used to both set 'reading' (to optionally configured values) and publish to configured topic</p>
</li>
<li>
<p><code>attr &lt;name&gt; autoSubscribeReadings &lt;topic&gt;</code><br/>
specify a mqtt-topic pattern with wildcard (e.c. 'myhouse/kitchen/+') and MQTT_DEVICE automagically creates readings based on the wildcard-match<br/>
e.g a message received with topic 'myhouse/kitchen/temperature' would create and update a reading 'temperature'.<br/>
Please note that topics with spaces will not work here!</p>
</li>
<li>
<p><code>attr &lt;name&gt; subscribeReading_&lt;reading&gt; [{Perl-expression}] [qos:?] [retain:?] &lt;topic&gt;</code><br/>
mapps a reading to a specific topic. The reading is updated whenever a message to the configured topic arrives.<br/>
QOS and ratain can be optionally defined for this topic. <br/>
Furthermore, a Perl statement can be provided which is executed when the message is received. The following variables are available for the expression: $hash, $name, $topic, $message. Return value decides whether reading is set (true (e.g., 1) or undef) or discarded (false (e.g., 0)).
</p>
<p>Example:<br/>
<code>attr mqttest subscribeReading_cmd {fhem("set something off")} /topic/cmd</code>
</p>
</li>
<li>
<p><code>attr &lt;name&gt; retain &lt;flags&gt; ...</code><br/>
Specifies the retain flag for all or specific readings. Possible values are 0, 1</p>
<p>Examples:<br/>
<code>attr mqttest retain 0</code><br/>
defines retain 0 for all readings/topics (due to downward compatibility)<br>
<code> retain *:0 1 test:1</code><br/>
defines retain 0 for all readings/topics except the reading 'test'. Retain for 'test' is 1<br>
</p>
</li>
<li>
<p><code>attr &lt;name&gt; qos &lt;flags&gt; ...</code><br/>
Specifies the QOS flag for all or specific readings. Possible values are 0, 1 or 2. Constants may be also used: at-most-once = 0, at-least-once = 1, exactly-once = 2</p>
<p>Examples:<br/>
<code>attr mqttest qos 0</code><br/>
defines QOS 0 for all readings/topics (due to downward compatibility)<br>
<code> retain *:0 1 test:1</code><br/>
defines QOS 0 for all readings/topics except the reading 'test'. Retain for 'test' is 1<br>
</p>
</li>
<li>
<p><code>attr &lt;name&gt; useSetExtensions &lt;flags&gt;</code><br/>
If set to 1, then the <a href="#setExtensions">set extensions</a> are supported.</p>
</li>
</ul>
</ul>
