No matching entities found for weather.get-forecast

I’ve just installed 2023.9 and was going to have a look at the new weather.get_forecast service.

When I go to Developer Tools > SERVICES and try to use this service I run into an issue. When I try and select an entity I’m told that there are no matching entities.

I’m using the native Met Office integration.

What am I doing wrong? Do I not need to worry about attribute deprecation for this integration?

Looks like that this integration is not yet ready for the new setup, check here or raise a ticket

Are those issues specific to the met office integration ?

I am using Meteorologisk Institutt (Met.no) integration and it shows 2 entities, Home and Home Hourly that I appear to be able to use as targets for the new weather.get_forecast service call.

However, I can now update the entities using the new service call, AND the integration itself is updating the entities as they change (current behaviour). Is there a way I can just use the new method only ?

UPDATE:-

I think I literally answered my own question when I found this dialog:
