Is it possible to show the Maximum of date time value in Powerbi as you can do for integer fields?
I want to see in a tile last time an event received and the value for that sensor event.
Yes it is possible. You will create a Measure in your data model like: MaxDate:= MAX(Table[Datecolumn])
then you'll have a table with a single row, let's call it: DescriptiveStatistics
You can add this using Power Query if you'd like. In Power Pivot you'll add a calculated column named "Max Date" with expression: =MaxDate
Then you'll use the DescriptiveStatistics[Max Date] column in your Power View.
