Wrong value

[hekmanViii]

The sensor Ecu energy Today counts up the produceced energy, but once in a while is records the total energy of that day instead of the last xx miniutes. Which results in double the energy produced.

ik think I have the same, but do you mean the hole dat double or only a one time reading double. For me its a one time reading only :)

20 minutes before every thin was fine !!

[Ganzhans]

and is it possible to correct it by hand and ...... how ?

[hekmanViii]

Yes its reading the total day value (till that moment) instead of the use fort hat moment.

So its reading like: 0,25 kWh, 0,35 kWh, 11,60 kWh, 0,25 kWh.

I can correct this by going to [development tools] [statisics]

Search for ecu.

[ECU today Energy]

Clikc on the icon far right.

Find the time and correct the number.

I see the [ECU today Energy] entry but I don't now what the correct values mus be ....... I edit some thing, but when en where can I see the new values Engery values on the live section or energy dashboard also ?

See post before this happens about once or twice every week. The day total comes in place of the total for 19:40. I have to correct this or my stats will be disrupted.

I am currently evaluating a change that uses the historical data that the ECU stores. This has a number of advantages, including a correct display of Energy Today in /100 resolution (Wh) regardless of HA restart. There's initially a small difference between the ECU/HA value of Energy Today and the EMA site. I noticed that the EMA data is being corrected after the ECU finished maintanance in the evening after sundown. Hopefully this weekend I'll be able to prepare a pre-release.

The pre-release v1.2.31b contains an extra ECU query that introduces (part of) the use of energy history data. This is a query I previously described but was never needed (we thought). To compensate load time for the integration, I shortened the sleep-time between opening and closing the port. I also introduced the keepalive, a careful introduction to removing this sleep-time and keeping the port open. Success will depend greatly on compatibility with different ECU models and firmware. If you own an older model starting with 2160xxxxxxx ECU-R, you can even leave out the open/close functions, but does this work for other ECU models? I could make it optional in the UI settings. Anyway it should solve this issue. Please let me know if it does so that I can close the issue.

@hekmanViii @Ganzhans

If you are trying v1.2.31b you might have an issue with the Today Energy. I have forgotten to specify END in the suffix.

Line 38 of APSsystemsSocket.py should be changed from self.ecu_energy_history_suffix = "END00\n" to self.ecu_energy_history_suffix = "END00END\n". Then restart HA and see if that made a change to Today's Energy.

[HAEdwin]

I'm pretty sure Today Energy's issue has been resolved for the ECU-R, ECU-B and ECU-C. I'm closing this issue, if anything pops up, feel free to create a new issue. Notice that there might still be a small difference between the ECU en EMA values. EMA does it's own calculation but is sometimes adjusted by the maintenance interaction with the ECU in the evening.
