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,

Hello, we have discovered your products and we are amazed by the quality of your recorders!

What does the optional extended mention mean when buying a recorder?

And for it to apply the version with wifi antenna is more suitable?

Thank you in advance for your return.

Hi,

our device is not connected anymore at the server. 
Is that the server is down ?
