Heat amount decreasing, but state_class is total_increasing #235

Open ChrisMisker opened 5 months ago

ChrisMisker commented 5 months ago

The sensor heat_amount_heating has a state_class of "total_increasing", but sometimes I see a decrease in the amount of heat generated. That's strange, isn't it? Seems like that shouldn't be possible.

Please connect an USB-Stick to your heatpump and activate the data logger. Then look into it and validate that the peaks are not in the data from the Luxtronik data logger.

@BenPru I've got the data... but no idea how to open them. Can you point me in the right direction?

ChrisMisker commented 4 months ago

Another strange thing happened last night:

I have the datalogger downlad, but no idea what to do with it.

You should find three files: DTA+CSV+ERR The CSV can you open with Excel. See also: https://www.youtube.com/watch?v=9cUT0Vh4x2Y https://www.haustechnikdialog.de/Forum/t/174914/Luxtronik-II-Datenlogging

OK, so I have the data... and I also have OpenDTA (DTAgui) and loaded the data... but most of the variables are in German or shortened, so I have no where to look. I have also exported the data to csv and opened it in Excel, but I can't find any data corresponding to heat amount heating (luxtronik key 0151 calculations.ID_WEB_WMZ_Heizung). I really want to figure this out... because it's messing up my COP calculations. ;-) Can you help? I can send the data file.

Are you sure your heat pump controller hasn't restarted? I have seen several people on a german forum report crashes with version 3.89.x of the firmware.

Yes, sure that could be the reason for my 2nd message here. But the first message, where I show the sensor decreases, while this shouldn't be possible. That's strange behavior...

With the current firmware (don't know if that was the case before) the Heatpump seams to "correct itself". Another situation where a decrease can be seen, is during deicing (Abtauen). Seems to be normal. My Luxtronik is crashing is well and sometimes it destroys my statistics.

Same here: https://github.com/BenPru/luxtronik/issues/215
