Hi

Added folder: \config\custom_components\valutase
And there I put valutase.py as sensor.py.

Updated config.yaml with
#Valuta-Omvandlare

• platform: valutase

But at restart HA i get
The system cannot restart because the configuration is not valid: Platform error sensor.valutase - Integration 'valutase' not found.

Also tried to add modified init.py , manifest.json files. That didnt make any differens
