+```
+items:

+       background: "square" # choose which type of background you want behind the image. Can be one of: square, cicle, none. Defaults to none.

+**Remarks:**
+If for some reason your city can't be found by entering the name in the `location` property, you could also try to configure the OWM city ID in the `locationId` property. To retrieve your specific City ID, go to the [OWM website](https://openweathermap.org), search for your city and retrieve the ID from the URL (for example, the City ID of Amsterdam is 2759794).
