How to Aggregate Temperature Column Per Hour Per Day

Hi, Ibrahim_shaik 

May I ask if you have already solved this problem? On top of the DAX you wrote, just add an ALL.

Measure:

Expected = 

VAR CurrentDate = MAX('AmbTemp'[date])
VAR CurrentHour = HOUR(MAX('AmbTemp'[time]))
RETURN
    CALCULATE(
        AVERAGE('AmbTemp'[t_out]),
        FILTER(
            ALL('AmbTemp'),
            SELECTEDVALUE('AmbTemp'[date]) = CurrentDate &&
            HOUR('AmbTemp'[time]) = CurrentHour
        )
    )
