# [SOLVED] Sum of values from beginning of month

Hi,

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!
