Filtered virtual values

Akikaa 1 month ago in Dashboard and Widgets updated by Support Manager 1 month ago 3

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

Extended

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.

Indexation of tariffs

Иван 4 years ago in Dashboard and Widgets updated by Support Manager 1 month ago 6

Electricity tariffs change every six months. How to change the current tariff is clear, but in this case the statistics for previous periods will be recalculated?! How do you leave history untouched? Otherwise, the true expenses for past periods will not be correct!

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.)
