How to change this "unknown" state to "close"

Configuration
1

Hello,

does anyone could help me to change the state from “€ unknown” to “closed”.
This state is since the Gasstation is currently closed, therefore this sensor does not habe an excepted value. I could imagine that this is possible with an “if”, “then”, “else” but I don’t know the correct syntax.
