Hello,
How can I change the dashboard theme from black to white?

Thanks in advance for your help.

управление аналоговыми данными
Ciao a tutti, ho un problema con la gestione dei dati analogici. L'unità centrale raccoglie i dati analogici in volt, che corrispondono esattamente alla percentuale di apertura della valvola. L'apertura della valvola al 100% corrisponde ad una portata di 20 m³/ora.
Esempio:
dati raccolti 1,97 V = 19,7%
100% = 20 m³/ora
Ho difficoltà a creare dashboard coerenti, soprattutto nel calcolo dei consumi periodici, non capisco come gestire i consumi.
Ho notato che recuperando i dati "mensili", il valore su cui si basa il calcolo è il valore medio del volt, ad esempio 0,4 V. E se lo moltiplico per 20 m³, il risultato non è corretto.
Qualcuno può aiutarmi?
Indexation of tariffs
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.)
