<li>userReadings<br>
A comma-separated list of user-defined readings. Each definition has the form
<code>&lt;reading&gt; { &lt;perl code&gt; }</code>. After a single or bulk
readings update, the user-defined readings are set by evaluating the <a href="#perl">
perl code</a>
<code>{ &lt;perl code&gt; }</code> for all definitions and setting the value of
the respective user-defined reading <code>&lt;reading&gt;</code> to the result.<br><br>
Examples:<br>
<code>attr myPowerMeter userReadings power { ReadingsVal("myPowerMeter","count.A",0)/1250.0;; }</code><br>
<code>attr myMultiMeter userReadings power1 { ReadingsVal("myMultiMeter","count.A",0)/1250.0;; },
power2 { ReadingsVal("myMultiMeter","count.B",0)/1250.0;; }</code>
