i was connected my D103 smart meter and i have virtual value of sum of all devices ,
now how can i subtract or add the value of my real device with this virtual
both are same parameter iam going to sum or subtract (like sum of all power with power of single device) 

i was setup condition and set email notification for my smartmaic D105 temperature sensor
but even the condition is true mail is not sending
also i cannot find when ican set the destination mail and how can i configer the mail content also
there is no option to set it in device and aslo cannot find in dashboard also

i was added my all device power and make a virtual value total , 
now i need to add a fixed value like 14 with the virtual , even i try with function there is no option to read virtual value inside the function

Is it possible to connect at the same time this both sensors?

Hi,

I would like to know if it is possible define a particular function as virtual value where I can filter the data according a single or multiple conditions (example greater than o less than a value and to have in this way a new virtual value). I have a photovoltaic panel and I would like to have a view where I can see the total energy unused and fed into the network. Is there a way to obtain that in some way? I have seen that as virtual value I can define only a function with arithmetic operations. I would be useful to have other operations in the operator's list

Thanks,
