Hello
did you fix the problem? Same for me - incorrect entity values. My inverter is sofar ktlx 5.5 and logger LSE-3.
Regards

[aerucu]

Hello @d4ystek, unfortunately, the problem has not been solved. For the time being, I am using my LSW-3 with the Solarman integration again.

[aerucu]

Hello @d4ystek, I have replaced my LSE-3 but the fault has not been fixed. I can therefore rule out the inverter and the LSE-3 logger as the source of the error. My problem is that the generation is displayed with an extreme time delay.

Same here with HYD20KTL-3PH and LSE-3 on ME_0D_270A_1.09 and SolaX Inverter Modbus 2025.01.08.
I first installed 2024.12.x on December 26th and with that version it was running flawlessly.
Maybe some UTC/timezone conversion problem on the newer versions?
Is there a safe way to downgrade the SolaX Inverter Modbus?

[aerucu]

@konwin, I was recommended to use version 2025.01.6. I was also recommended to increase the polling intervals. I had set 10s everywhere.

You can downgrade by downloading Solax Modbus Integration again under HACS. There you can also select the version you want to downgrade to in the drop-down menu.

According to @cschlipf, version 2025.01.8 uses a newer version of pyModbus, which is probably causing this problem.

[konwin]

Downgrading did not work. I could install 2014.12.02 of SolaX Inverer Modbus but when trying to configure it I get:

Error

Config flow could not be loaded: {"message":"Invalid handler specified"}

Maybe this is related to the pymodbus version?! I think the newer version is still active in the background and 2024.12.02 won't start with this newer version.
I couldn't find a how to downgrade pymodbus for now...
