    Hi Ibrahim_shaik 

    Have a last year column in the Main Table using the Date column that you have:
    LY Date= DATEADD('MainTable'[Date], -1, YEAR)

    We can achieve the previous year value using LOOKUP:

    Temperature_LY =
LOOKUPVALUE(
    'MainTable'[Temperature],
    'MainTable'[Date], 'MainTable'[LastYearDate],
    'MainTable'[Time], 'MainTable'[Time]
)

    Do the same for Humidity and since Power is from another table:

    Power_LY =
LOOKUPVALUE(
    'PowerTable'[Power],
    'PowerTable'[Date], 'MainTable'[LastYearDate],
    'PowerTable'[Time], 'MainTable'[Time]
)

Hi Ibrahim_shaik 

This could be used to get the last year: LastYearDate = DATEADD('Date'[Date], -1, YEAR)

and if you actually want to calculate the measures for last year as well. Something like this would suffice:
Temperature LY =
VAR LDate = DATEADD('Date'[Date], -1, YEAR)
RETURN
CALCULATE(
AVERAGE('MainTable'[Temperature]),
FILTER(
ALL('MainTable'),
'MainTable'[Date] = LDate &&
'MainTable'[Time] = SELECTEDVALUE('MainTable'[Time])
)
)

Please provide more context if this is not what you are looking for.
