Using sliding window no results output

[wild-River2016]

使用滑动窗口（SLIDINGWINDOW）创建温度持续30秒大于75度的规则，没有结果输出。
规则：
select temp from stream1 group by SLIDINGWINDOW(ss,30,30) over (when temp > 75) having min(temp) > 75
测试数据：
{"deviceId":100,"temp":70.1}
{"deviceId":100,"temp":76.1}
{"deviceId":100,"temp":77.1}
{"deviceId":100,"temp":79.1}
{"deviceId":100,"temp":79.1}
{"deviceId":100,"temp":79.1}
{"deviceId":100,"temp":80.1}

Environment:

• eKuiper version (e.g. 2.0.0):

What happened and what you expected to happen:
麻烦看一下配置规则是否正确，如何才能输出结果。
期望能得到案例集锦中（总电流持续10s超过200A）的效果。

Having min(temp) > 75 is false. Additionally, SLIDINGWINDOW(ss,30,30) over (when temp > 75) will trigger after 30 seconds. Use SLIDINGWINDOW(ss,30) over (when temp > 75) may be what you want.
