Need a solution to custom $__timeFrom() $__timeTo() Linked server query

Hello again,
I need a query to build with the start/stop time from the grafana page.

The query below works:

SELECT value as value,TimeStampSeconds as time FROM OPENQUERY
(HISTORIAN, 'SET starttime=now-1d/d, endtime=now/d, samplingmode=Calculated CalculationMode = average, IntervalMilliseconds = 900000
SELECT * FROM ihRawData where tagname like SERVER010Utilties ')

This query not ( with $__timeFrom() and $__timeTo()

SELECT value as value,TimeStampSeconds as time FROM OPENQUERY
(HISTORIAN, 'SET starttime= $__timeFrom(), endtime=$__timeTo(), samplingmode=Calculated CalculationMode = average, IntervalMilliseconds = 900000
SELECT * FROM ihRawData where tagname like SERVER010Utilties ')

running error Status: 500. Message: db query error: sql: expected 18 arguments, got 0
without the () after the time no error but no data

So what i’am i missing here, do i need to transform the date and time ?

In de DB the data looks like this

Found something that works but not as aspected, only if i add -1d/d to the timefrom i get some data.
