不同用户的Drools规则

我最近开始使用Drools Fusion进行编程，并且我有一个智能可穿戴设备，可以将计步器和心率数据发送到我的笔记本电脑。然后，我使用drools规则语言处理此数据。但是，假设我有多个智能可穿戴设备，每个智能设备都有一个唯一的MAC地址。我使用时间窗口，我的问题是如何更改规则文件，以便规则仅针对具有相同macaddress的事件触发，并根据此MAC地址采取适当的措施。我当前的规则文件如下：

import hellodrools.Steps
import hellodrools.HeartRate
import hellodrools.AppInfo

declare AppInfo
    @role(event)
end

declare Steps
    @role(event)
end

declare HeartRate
    @role(event)    
end


rule "ACC STEPS RULE"
when
    accumulate( Steps( $s : steps )
                over window:time( 1h ) from entry-point "entrySteps"; 
        $fst: min( $s ), $lst: max( $s );
        $lst - $fst < 50 )
then
    System.out.println("STEPS RULE: get moving!");
    System.out.println($lst + "   " + $fst);

end

rule "HEARTRATE RULE 1"
when
    $heartrate : HeartRate(heartRate >= 150) from entry-point "entryHeartRate"
then
    System.out.println("Heartrate is to high!");
end

rule "HEARTRATE RULE 2"
when
    $heartrate : HeartRate(heartRate <= 50 && heartRate >= 35) from entry-            point "entryHeartRate"
then
    System.out.println("Heartrate is to low!");
end

rule "HEARTRATE RULE 3"
when
    $heartrate : HeartRate(heartRate < 35 && heartRate >= 25) from entry-point "entryHeartRate"
then
    System.out.println("Heartrate is critical low!");
end

rule "HEARTRATE RULE 4"
when
    $max : Double() from accumulate(
        HeartRate( $heartrates : heartRate ) over window:time( 10s ) from entry-point "entryHeartRate",
        max( $heartrates ) )&&
    $min : Double() from accumulate(
        HeartRate( $heartrates : heartRate ) over window:time( 10s ) from entry-point "entryHeartRate",
        min( $heartrates ) )&&
    eval( ($max - $min) >= 50 )
then
    System.out.println("Heartrate to much difference in to little time!");
end

我的HeartRate事件具有以下字段：

int heartRate;
Date timeStamp;
String macAddress;

我的步骤事件具有以下字段：

double steps;
Date timeStamp;
String macAddress;
