Script that uses "Counter Incremental" Energy

Hi.
I wonder if someone can help me write a script that uses "Counter Incremental" Energy?
I have a Bosch Compress 7000i AWE 13 kW air/water heat pump. I see, among other things, the heat pump's total energy consumption since the heat pump was installed via Domoticz unit "HP_Supp energy tot" for example 74364 kWh right now. I would like to see the daily or per hour energy consumption like the image below.

I have seen information about how the sensor itself works, but no information about how the script itself is written.
I don't know anything about writing Dzventz code or Lua code, so I'm wondering if someone can help me create a script that solves this?
Many thanks for your help!
Best regards,
McLund

You should not use a counter incremental but a normal energy counter. Then you get the hourly, daily, weekly, monthly etc overviews.
For a dzvents script you only need to update the total counter you get from the heat pump and put it in the counter with function
updateCounter(value) see also wiki

For an example script how to update a counter see

It collects P1 data and puts the calculation in Saldo Hoog (return - usage) and so on.

I am looking for a custom device in which I can store the hourly costs of gas / electric.
I read that I should not use a counter incremental but a normal energy counter.
But those counters are using the energy rates as defined with the setup.
I would like to store the hourly prices in a custom device using the dynamic hourly prices of my provider.
I already have a counter where I store my hourly gas /elec. prices.
How can I do that hourly calculation /storage with a custom device so that I have a hourly calculation of hourly gas/elec * hourprice gas/elec?
I would like to have the results in a domticz device like the energy counter since those counters have the hourly/daily etc graphs and tables.
Or should I use the JSON / API calls instead ?

In recent Domoticz, with the (dynamic) cost calculation activated in menu setup settings, tab meters, the energy costs are calculated automatically by Domoticz in the energy device you use. No need to have a separate device for that. Also in the log and reports pages of the devices the costs are shown per day, month, year etc.
And if you mean energy prices then a custom sensor would be enough to store the current price, that device can be used as input for the (dynamic) cost calculation in Domoticz.

Thank you for advising to a recent version. I'm testing it right now.
Do you know how its daily totals are being calculated within the monthly tables?
I'm expecting a sum of 24 calculations: 24* hourly price * hourly usage-delivery?

I don't know how they are calculated. But I guess the costs are calculated against the current prices (could change more that once an hour..).
