Entities for MPPT total kWh lost precision from 0,1 to 1 with update to v0.6.4

The problem

With update to version v0.6.4 the MPPT total kWh entity changed precission from 0,1 to 1. For small installations the precission of 0,1 is very helpful.
I use the diff, to show the history of the last days, what is not possible in winter (no sun), because it's updated onley ever 3-5 days by 1 kWh.

Environment

Home Assistant 2026.1
Victron HACS before v0.6.4
