Domoticz

I made a dzvents script to calculate the daily energy costs. I store these costs in dummy sensors. That works fine. I want to store these values in managed counters however. The advantage of managed counters is that you can have reports in the graphs view.
To test if this works I made an extra dummy managed counter.
I write the cost to the sensor at 23:59 hours using the command:
domoticz.devices('Dynamische energiekosten 2').updateCounter(Kostentotaal)
That works fine. I see the following in the devices tab:
The graph as well as the report remains empty:
I made a backup of the database and opened it in an SQLite viewer. There are no values in the Meter or Meter_Calendar tables.
I searched the forum and the internet, but could not find what I am doing wrong. Who can help?

Hi
I think you need to use .updateHistory to update the values

I already tried that. But the values were not saved in the csdb. Perhaps I should start again with a new managed counter and a simple script to store a fixed value and see what happens.

I do something similar all the time, the updateHistory works fine.

If you want to store a daily value in the meter_calendar table you need to use
domoticz.devices('Dynamische energiekosten 2').updateHistory(valueDate,valueString)
where valueDate is a date in format yyyy-mm-dd
and valueString is a string with 2 values separated by a semicolon.
The first value of valueString will be stored in the counter field (i.e. the cumulative value of all days).
The second value will be stored in the value field.
So you could start with
local valueString="0;"..Kostentotaal
and use that value in the updateHistory command.

Thank you all. It works! I tried it before using the updateHistory command. I probably made a mistake.
I now am going to rewrite the script to write the gas costs, the electricity costs and the total cost to managed counters.

Thanks again!

Just to be sure: if you have a device that has the current (dynamic) cost price of Electricity and Gas, Domoticz can calculate the total costs for you automatically now. No need to do fancy script things anymore with managed counters.

But please note that due to issue #5437 the costs calculated by domoticz will not be 100% correct and therefore not match the calculations of your electricity provider.

I run an integrity-check script on a regular basis which checks wether the value field in the dbase matches the difference between two consecutive counter fields and very often it does not match because of 5 minute values missing as explained in issue 5437.

I see issue 5437 was closed and I don't know how to reopen it (other than creating a new one).

I know, but I want to take everything into account. Also the fixed costs. I want to compare my new dynamic contract with a year contract, where I also take into account the fine (terugleverkosten) I have to pay supplying energy back into the net when I would have chosen a year contract.
Fixed costs are not taken into account when using the built-in energy cost calculation of Domoticz.

Perhaps you guys update Domoticz so it can handle all cost options?

@willemd, things have changed a lot since you have opened it 2 years ago. It was closed to no feedback. https://github.com/domoticz/domoticz/issues/5437

But if it it still an issue better create a new issue based on latest beta and give some examples so it can be reproduced.

I am not running beta but 2024.7

Once I collect a few examples over the comming days I will share in a new opened issue on github and
I will also share a small python program that can check the database and will list the errors.
All one has to do is indicate the device idx of a P1 device or a kWh device.

Issue created included example dbase entries and python program to check for this issue.
