Filtered virtual values
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.
The device is not connected anymore at the server.

Индексация тарифов
Тарифы на электроэнергию меняются раз в полгода. Как менять текущий тариф понятно, но в этом случае пересчитается и статистика за предыдущие периоды?! Как оставить историю не тронутой? Иначе истинные расходы за прошлые периоды будут не корректными!
To calculate a new tariff without losing data for the previous period, you need to make a complex expression.
- In the widget settings, in the Arithmetic operation select f(x)
- click on the Edit icon and set the conditions:
d.TIME < new Date(2022,0,1) ? d.Ch1*0.05 : d.TIME < new Date(2023,0,1) ? d.Ch1*0.06 : d.Ch1*0.07;
where
new Date(2023,0,1) is January 1, 2023
before January 1, 2022 at the rate of 0.05
before January 1, 2023 at the rate of 0.06
everything will continue at the rate of 0.07
Replace the values with your tariff accordingly.
With each tariff change, you can add a new line of conditions in the same format new Date(Year, Month, Day).
Note that the month starts at 0. (0 - January, 1 - February, ... , 11 - December.)
