Alerts

Hi,

I have a question about alerts. I've made a realtime report in Power BI with the machinestatus. The machinestatus can be Production, Planned Downtime, Unplanned Downtime and Startup Time. On each day, the Planned Downtime may not be more than 6 hours. I want to set an alarm, that if the Downtime is more than 5 hours, I want to get a warning by email. 

How do I set this warning?
