Based on home-assistant/core#54280 (not yet fully upstreamed Discovergy integration).
Please have a look and show your interest if you want this integrated into homeassistant releases.
The integration has been officially integrated with Home Assistant 2023.07 🎉 and can now be added without HACS. For more information see the integration page https://www.home-assistant.io/integrations/discovergy/.
This as custom HACS repo. Please see https://hacs.xyz/docs/faq/custom_repositories for installation instructions.
