[SOLVED] Sum of values from beginning of month


I want to compute the total power consumption values since the beginning of the month. I have the persistance set up (InfluxDB) but I cannot get the from-date computed correctly:

val beginningOfMonth = now.withTimeAtStartOfDay.minusDays(now.dayOfMonth())
var Number sumWatt = gWatt_Huset.sumSince(beginningOfMonth)

This code does not work since now.dayOfMonth() returns a Property, and not an integer.
Any ideas on how I can get this to work?

From top of my head, now.getDayOfMonth()

Yes! Thanks!
