Okay thanks
But it is possible (not using the plugin) but directly the Domoticz environment make a cumulative counter of the device value ?

Sorry...probably I am not be explain well... I use it and it works perfecly ( I talk about ENVIR CurrentCost with Domoticz, everything ok)
What I need is somewhere a table like this
MyHome:
JAN 2016 100 kWh
FEB 2016 125 kWh
MAR 2016 118 kWh
...
...

where the values is the sum of daily kWh cunsumed ...

Hi,
I am quite new on Domoticz... I am using it for controll power consummation with CurrentCost plugin in my ENVIR devices and it work perfectly with the instant power consumption.
I like to have report for daily/monthly total kWh consumption on my house...How can I do it ?

Thanks for your help ...
