Issue with Displaying Energy (Sum of consumed energy) in Module SPM01-U01

Hi all,

I have recently purchased and successfully integrated the BITUO TECHNIK SPM01-U01 module into my Home Assistant
However, I have noticed an issue with displaying the data, specifically with the SUM function (Sum of consumed energy), because no data is stored (null value)

I have conducted several tests and checks to ensure that the integration was done correctly, but the problem persists. I would like to inquire if other users have experienced this same issue and if they have found any solutions.

Thanks in advance for your help !
