Deltas (for RFXmeter)?

[Headworx]

Hi,

Is it possible to calculate / display deltas? Something like hourly / daily power consumption? RFXMeters report a counter value representing total power consumption since the beginning... While I would like to calculate / plot graphs representing hourly power consumption... so I would have to subtract previous_reading(an_hour_ago) from the current_reading(current_time). Is there a way to handle this properly?

Cheers,
Headworx

data sensors are handled as "numerical value" in graphs and you can select "deltasum" for these which plots the delta for the period selected as "time resolution".

Oh that is great, thanks!

Yes, that's works great, see graphic...
