<h3>expandJSON</h3>
<ul>
<p>Expand a JSON string from a reading into individual readings</p>
<ul>
<li>Requirement: perl module JSON<br>
Use "cpan install JSON" or operating system's package manager to install
Perl JSON Modul. Depending on your os the required package is named:
libjson-perl or perl-JSON.
</li>
</ul><br>
<a name="expandJSONdefine"></a>
<b>Define</b><br><br>
<ul>
<code>define &lt;name&gt; expandJSON &lt;source_regex&gt;
[&lt;target_regex&gt;]</code><br><br>
<li>
<a name="">&lt;name&gt;</a><br>
A name of your choice.</li><br>
<li>
<a name="">&lt;source_regex&gt;</a><br>
Regexp that must match your devices, readings and values that contain
the JSON strings. Regexp syntax is the same as used by notify and must not
contain spaces.<br>
</li><br>
<li>
<a name="">&lt;target_regex&gt;</a><br>
Optional: This regexp is used to determine whether the target reading is
converted or not at all. If not set then all readings will be used. If set
then only matching readings will be used. Regexp syntax is the same as
used by notify and must not contain spaces.<br>
</li><br>
<li>
Examples:<br>
<br>
<u>Source reading:</u><br>
<code>
device:{.*} #state without attribute addStateEvent<br>
device:state:.{.*} #state with attribute addStateEvent<br>
device:reading:.{.*}<br>
Sonoff.*:ENERGY.*:.{.*}<br>
.*wifiIOT.*:.*sensor.*:.{.*}<br>
(?i)dev.*:(sensor1|sensor2|teleme.*):.{.*}<br>
(devX:{.*}|devY.*:jsonY:.{.*Wifi.*{.*SSID.*}.*})
</code><br>
<br>
<u>Target reading:</u><br>
<code>.*power.*</code><br>
<code>(Power|Current|Voltage|.*day)</code><br><br>
<u>Complete definitions:</u><br>
<code>define ej1 expandJSON device:sourceReading:.{.*} targetReading
</code><br>
<code>define ej2 expandJSON Sonoff.*:ENERGY.*:.{.*} (Power|.*day)
</code><br>
<code>define ej3 expandJSON (?i).*_sensordev_.*:.*:.{.*}
</code><br><br>
</li><br>
</ul>
<a name="expandJSONset"></a>
<b>Set</b><br><br>
<ul>
N/A<br><br>
</ul>
<a name="expandJSONget"></a>
<b>Get</b><br><br>
<ul>
N/A<br><br>
</ul>
<a name="expandJSON_attr"></a>
<b>Attributes</b><br><br>
<ul>
<li><a name="expandJSON_attr_addReadingsPrefix">addReadingsPrefix</a><br>
Add source reading as prefix to new generated readings. Useful if you have
more than one reading with a JSON string that should be converted.
</li><br>
<li><a name="expandJSON_attr_disable">disable</a><br>
Used to disable this device.
</li><br>
<li><a name="expandJSON_attr_do_not_notify">do_not_notify</a><br>
Do not generate events for converted readings at all. Think twice before
using this attribute. In most cases, it is more appropriate to use
event-on-change-reading in target devices.
