Group by a Set Time Interval

[numersoz]

Hi,

I have timestamped sensor data. Data is available every hour. I'm trying to flag this data by when it is below a value four consequtive hours.

One solution to this that I thought is to group the data by 4 hour internals. So instead of having a row for each hour, I would have a row for every 4 hours.

Is this possible to be done in DAX or Power BI? Would be nice to simply group by 4 hour intervals.

Thanks

@numersoz , Try to create a Time Table - https://kohera.be/blog/power-bi/how-to-create-a-time-table-in-power-bi-in-a-few-simple-steps/

Create a four-hour interval there. Join with the time part of your date.

Time part = [Date time].time
