Since some weeks, the VRM portal do no more update the correct battery voltage.
That's different up to this summer.
Only 26.6V is shown over the whole day now.
When I open the remote console of my two charge controllers (100/30) I see that the maximum voltage of 28.8V has been reached during the day (LiFePo4 batteries), but it wouldn't be recorded in the Online-Portal.
That's stupid because in next winter I will no longer see the current state of charge.
We live 850km from our holiday home and we have a video surveillance that must be guaranteed.
What going wrong? What can I do?
