Energy tariff gone after new P1

Hi,

I swapped my diy P1 meter for a Home Wizard P1
I changed the name of the new sensor to the old ones to keep the numbers correct, though now it’s not as expected.

Every costs of the past is gone and 2 days have a huge negative value.

Today I will receive a new water meter sensor and don’t want to make the same mistake…

And if possible I’d like to get the old costs back.

Need some help please,

Dutchy
