Hi!
I need a little help.
I would like to calculate the electricity consumption balanced from the values of the Shelly 3EM.
I would like the energy consumption as billed by the energy supplier.
I hope this is understandable?!
In German we say “saldierend”
I found the Solution
Can you post the code? I’m facing the same problem!
It is more than a code…and it is a little complicated…
Bute the answer is here:

First you need 10 Items:
You must change your persistence service to JDBC.
Then make a file for JDBC:
jdbc.persist:
Strategies {
everyMinute : "0 * * * * ?"
everyHour : "0 0 * * * ?"
everyDay : "0 0 0 * * ?"
default = everyChange
}
Items {
Shelly3EMSHEM3_KumulierterVerbrauch : strategy = everyChange, everyMinute, everyDay, restoreOnStartup
Minute_Einspeisung : strategy = everyChange, restoreOnStartup
Minute_Verbrauch : strategy = everyChange, restoreOnStartup
Minute_Ges_Einspeisung : strategy = everyChange, restoreOnStartup
Minute_Ges_Verbrauch : strategy = everyChange, restoreOnStartup
Minute_Tageseinspeisung : strategy = everyChange, restoreOnStartup
Minute_Tagesverbrauch1 : strategy = everyChange, restoreOnStartup
Stromkosten_Summe : strategy = everyChange, restoreOnStartup
Stromkosten_Tag : strategy = everyChange, restoreOnStartup
Einspeisung_Summe : strategy = everyChange, restoreOnStartup
Einspeisung_Tag : strategy = everyChange, restoreOnStartup```
}
Make 1.Rule:
rule "Strom & Einspeisung"
when
Item Shelly3EMSHEM3_KumulierterGesamtverbrauch received update
then
Stromkosten_Tag.postUpdate(Minute_Tagesverbrauch1.state as DecimalType * 0.28)
Stromkosten_Summe.postUpdate(Minute_Ges_Verbrauch.state as DecimalType * 0.28)
Einspeisung_Tag.postUpdate(Minute_Tageseinspeisung.state as DecimalType * 0.044)
Einspeisung_Summe.postUpdate(Minute_Ges_Einspeisung.state as DecimalType * 0.044)
end
Make 2.Rule:
home.sitemap:
Frame label="Verbrauch & Einspeisung" {
Text label="Übersicht" icon="energy" {
Frame label="Verbrauch & Einspeisung" {
Text item=Minute_Ges_Verbrauch label="Gesamtverbrauch ab 01.08.2021 [%.3f KWH]" icon="boese"
Text item=Stromkosten_Summe icon="money_red"
Text item=Minute_Tagesverbrauch1 label="Verbrauch heute [%.3f KWH]" icon="boese"
Text item=Stromkosten_Tag icon="money_red"
Text item=Minute_Ges_Einspeisung label="Gesamteinspeisung ab 01.08.2021 [%.3f KWH]" icon="smiley"
Text item=Einspeisung_Summe icon="money"
Text item=Minute_Tageseinspeisung label="Einspeisung heute [%.3f KWH]" icon="smiley"
Text item=Einspeisung_Tag icon="money"
}}
Then it look like this:

Thanks!
Hi there.
How does the blockly Script with Rule DSL ?
Would this also possible?

I know it’s not OpenHab, I use Home Assistant instead, but maybe you can transfer some of the logic to OpenHab:
