You'd have to insert the new ZZZTracker in the first rule.<br><br>But this does not compute the average over three values in a <i>sliding </i>window; you'd compute the average for every <i>adjacent </i>window of three events.<br>
<br>Stay with the original rule, but use a "Tracker" for counting valid ZZZSensorBeans, and add another pattern to the original rule: the suitable Tracker must have a count >= 3.<br><br>-W<br><br><div class="gmail_quote">

Hi all,<br>
<br>
Sorry, the first rule should read:<br>
<br>
when<br>
$mds : ZZZSensorBean(temperature > 30)<br>
not ZZZTracker(profileID == $mds.profileID)<br>
<div class="im">then<br>
ZZZTracker $tracker = new ZZZTracker();<br>
$tracker.profileID = $mds.profileID;<br>
end<br>
<br>
