What is the price that I pay?

[sofehr]

Not an issue. Actually not even a question about the integration, but I could find an answer otherwise. Which is the price that Frank Energie charges me for the electricity I consume? I was expecting this to be the all-in price; however, when I do the math, the numbers I get are consistent with what the sensor “Average electricity price today including tax and markup” provides. Do you, or anyone else, know?

It's not that simple. Please anyone who knows more about this answer it. It's current electricity price including tax and markup + energiebelasting + subscription fee - korting energiebelasting. And this are only the variabel costs. Then there are fixed costs including vastrecht etc. See electricity bill. Again. If anyone knows the exact calculation can answer this.

Thanks for the prompt reply. As far as I can see, the invoice lists "Vaste leveringskosten", "Energiebelasting & ODE", "Vermindering energiebelasting" and "Netbeheerkosten" as fixed costs (well, the "Vermindering energiebelasting" is a deduction that almost covers the others). As for the variable costs, i.e., the costs per kWh, the invoice simply lists the kWh and the Euro total for the month. If I look in the app though, where I can see the kWh's and costs for each individual hour, the numbers there are consistent with the value of the sensor “Average electricity price today including tax and markup” (which corresponds to the Marktprijs+ in the app, as far as I can see). If the above is how it is, I don't understand the purpose/meaning of the all-in price then.

[sofehr]

Oh, I only see now that on the app it says that "net zoals op je factuur rekenen we met de marktprijs+", whose value matches up with that of the above mentioned sensor. That seems to confirm my observation above. My apologies for abusing this thread for this purpose. What remains unclear is the purpose of the all-in price.

The all-in price is the actual price @HiDiHo01

energiebelasting is not fixed but dynamic, however they put an estimate as fixed cost and you get an end-of-year equalizing bill.

(Energiebelasting is eigenlijk gewoon per kwh maar op factuur doen ze 1/12e deel van de jaarschatting en achteraf verekenen ze het verschil.)

[sofehr]

Thank you, @tbrasser . That's a weird system, to charge most of the variable costs on a per-use basis, except for the energiebelasting for which they do a monthly estimate and then adjust at the end of the year. But that's how it is then...
