ebusctl write command is done but the value is not changed

[alyk]

Hello!
I modified CSV config for my Vaillant Ecotek in order to set StorageTempDesired from EBUS.
It shows command is done successfully but in fact the value is not changed.
thanks for any idea

2ad9b828-ebusd:/# ebusctl w -c bai  StorageTempDesired 63.00
done

2ad9b828-ebusd:/# ebusctl r -f StorageTempDesired
62.00
