No entities created for FutureNow

I’m new to HA, I have added the config lines to my configuration.yaml
based on the example here https://www.home-assistant.io/integrations/futurenow/
but no entities have been created.
As far as I understand FutureNow is included in the flash image with latest core-2021.3.4 version running on a RaspBerry PI 3 model B+

Check confifuration is ok.

What else do I have to do?
