We have a Thingsboard CE setup running in a custom server. All panels are working perfect, and one of them is showing the pulses count of 3 water meters at a remote location. Right now in the order of 80.000-130.000 pulses, equaling each pulse to m3 (cubic meters=1000 liters). Our client would like to see a quick summary of water used in the day, thus the actual count of one of the 3 counters, minus the count it had today at 0:00h. Is this easy to perform in Thingsboard panels? I've seen delta calculations but those are for current-previous value I believe. Also I've seen other doing it for other versiones (Professional Edition) but our (CE) lacks some specific areas or functionalities. Is this doable on this version?

Thanks!
