IOT Device Status (Data look up by ID)

Hi, I am new in PowerBI. I want to monitor some of my IoT Device by PowerBI Dashboard But I am unable to create the formula to DeviceID lookup on the date and create a new table

 

My Devices are generating this report

Hi @James_CA 

You need to build a calculated table ,add a calculated column and use measure to achieve your goal.

I build a table like yours to have a test.

Table (Add a calculated column and format the Data type as Date):

Date = 'Table'[Datetime]-TIMEVALUE('Table'[Datetime])

AllDeviceID:

Build a Date Table:

Date = 
GENERATE (
    CALENDAR ( DATE ( 2020, 09, 01 ), DATE ( 2020, 09, 04 ) ),
    AllDeviceID
)

 Measure:

Measure = 
VAR _Datevalue =
    CALCULATETABLE (
        VALUES ( 'Table'[DeviceID] ),
        FILTER (  'Table' , 'Table'[Date] = MAX ( 'Date'[Date] ) )
    )
RETURN
    IF ( MAX ( 'Date'[DeviceID] ) IN _Datevalue, "True", "False" )

Build a matrix visual to see the result.

Create a date column //prefer

Date = [Datetime].date //Prefer way is join it with Date table

 

Count occurrence=Count(Table[Date]) // or Count(Table[Datetime])

 

if (isblank([Count occurrence]) , "False","True")

 

Use it in matrix with Device Id and date

Hello,
