Re: [rules-users] Why this rule fires immediately ?

You'd have to insert the new ZZZTracker in the first rule. But this does not compute the average over three values in a *sliding *window; you'd compute the average for every *adjacent *window of three events. 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. -W On 19 October 2011 12:28, eskomk <esko.hujanen(a)ebsolut.fi&gt; wrote:
