I want to choose the temperature value of the closest minute to the hour

[Anonymous]

I have a temperature sensor that measures temprature every some minute and I want to choose the temperature value of the closest minute to the hour.How Can I do that?

For example, for 23 o'clock I want to choose the value of the closest minute to 23 o'clock.

Hi Samrawit21,

Create a measure to achieve the minimum interval using DAX below:

Minimun Interval Column = 
VAR temp = ABS(ABS(DATEDIFF(DATE(2018, 6, 9), MIN(Table1[Dateum]), SECOND)) - 23 * 60 * 60)
VAR hour = ROUNDDOWN(temp / 3600, 0)
VAR minute = ROUNDDOWN((temp - hour * 3600) / 60, 0)
VAR second = MOD(temp, 60)
RETURN
TIME(hour, MINUTE, second)

 

Then obviously you can find the nearest date, just sort [Minimum Interval Column]

I want to write a function which chooses the temperature value of each hour. in the attached image of my previous question, you can see that the sensor measures every 5 minutes so the function should choose one value when the minute is close to the hour.
for example 06/09/2018 23:14:41 is close to 23:00 so the function must choose the temperature value of that time, and 06/09/2018 23:59:48 is close to 00:00:00(12:00 AM)...

I hope my question is clear enough.
