Dashboard item value aggregated for today.

[celiorod]

Hello all,

First question here.

I have item that queries every 10min for a value and keeps track of changed value(ex: 1000, 1200, 2000,...) i want to sum this values for today only, we can to a time periodo (now-24h), we would like to aggreate from 00:00 until now.

Thanks in advance for your attention.
