I am living in Belgium and the local energy supplier company (https://www.fluvius.be/) provides a web portal to check your consumptions for electricity and gas (if you have digital meters).
they also seem to allow third parties to integrate (see this app from local energy provider Engie https://apps.apple.com/gb/app/engie-belgië/id1562119194) and withdraw:
- consumption history at different granularity ( daily, hourly, 15 min)
- consumption peaks
which makes me think that Fluvius has indeed an API available (Ontsluiten van verbruiksdata via API | Fluvius).
What I cannot figure out is if this is available to the general public or only if you are a company (Engie) and would like to provide services to your customers.
I have found also another company that integrates with Fluvius (https://www.energyid.eu) but their services are exaclty what I would like to achieve with Home Assistant (and not depend on other’s shady ML analysis).
Has anyone info on this provider?
