Day and month plot numbers are gone.

[ycagwyn]

All of a sudden the day and month plot numbers were replaced by some very huge numbers. I have tried to patch the figures into the .cfg file and after some struggle managed to upload them to the device. Graphs looks OK until there is a change of hour when it gets back to show one very large number for previous hour. Downloaded the configuration after upload and noticed that the latter half (export) of day and month plot series were missing. Instant power readings are still transmitted OK to the MQTT-server every 10 second while energy measurements looks as bad as on the GUI.

Huh, interesting. Do you see any sign in your data that this could be a number format / rollover error? What order of magnitude are the "normal" numbers?

[ycagwyn]

Hi Arnie!

Thank you for the quick reaction. Since I’m not that closely familiar with the product I cannot tell whether it’s format /rollover problem or not but I would guess so. My normal daily import/export readings are 0-60 kWh and hourly 0-15 kWh. This is how it looks today: 

Daily figures seemed OK after my path yesterday and here is what the downloaded .cfg says now:

I see nothing special about those values, just normal household consumptions.

So where is the problem...

You marked off the total accumulated energy meter reading yesterday: Is this the wrong value? This should correspond to the value you see on the LCD screen of your meter. What do you see on the meter LCD? A photo would be great.

Thank you, that is interesting. Your LCD seems to show 3 decimals..? Mine does not show decimals on the LCD.

Is the accumulated export value also wrong in your GUI?

[ArnieO]

Can you run a Telnet debug so that we can see what data the meter sends? https://www.amsleser.no/module/ets_blog/blog?id_post=24

[ycagwyn]

According to the netowner Boo Energi and the PV readings from APSystems ECU-C I have exported around 3800 kWh since installation end of June 2023 so I guess that is what should be presented as accumulated export. I'll try to run a Telnet debug as soon as I figured out how its done on Mac

Good question! I'd greatly appreciate if you could send me a short description when you find out, so that I can add that information to the bog post.

The kWh values in your GUI are off by a factor ten. Please open the config page and set multiplier to 0.1 to fix that. We think this could be a root cause for the issues you are seeing.

Is this something that suddenly happened, or did it show correct values previously? Maybe your meter has received a firmware update. We unfortunately have no way of knowing the number of decimals the meter sends, and it is not consistent. So in some cases a correction must be done by using the multipliers.

[ycagwyn]

Change of multipliers had no effect until I used dot(.) as decimal separator instead of comma(,) which is default at the GUI! Saw that decimals are used in Power saving dBm as well. Now my accumulated import and export numbers appears to be OK. Do you (as I) think it could be an idea to patch the plot numbers back into the cfg file?

[ArnieO]

It is unfortunately difficult to find a way to accept both decimal comma and point in the GUI, we are a bit stuck with the libraries we use.

Do you (as I) think it could be an idea to patch the plot numbers back into the cfg file?

If you mean editing the cfg file and load it back: Yes, sure. You can always keep a copy and revert if it does not do the trick. Editing the cfg file is a good way to restore in such a situation.

[ycagwyn]

So the conclusion is that my problem probably was caused by a firmware upgrade of the power meter which is fixed by changing multipliers kWh from 1 to 0.1. Also found that decimal sign used in GUI does not follow browsers locale. Thank you so much for your help. (I'll try Telnet on Mac and supply instructions if successful.)

Power meter firmware upgrade is my best hypothesis, if this suddenly appeared.

Unfortunately correct.

Thank you so much for your help.

You're welcome!

That would be great! 👍

(Please close thread if you consider issue solved.)

[ycagwyn]

Sorry but got this after reset of "Enable debugging" and reboot. Retried typing 0.1 as kWh multiplier. What did I do wrong, do I have to wait for accumulated figures?

[ycagwyn]

Yes wait was the answer, sorry about that.

Hello again. Promised make some notes regarding telnet on a Mac and this is what came out of it. Feel free to use it anyway you want. Telnet AMS-reader on Mac.pdf

Fantastic - thank you! Will add it to the blogpost ASAP.
