Hi
Hello, I have a Home Assistant application running on a mini PC with an i7 processor and Home Assistant OS. After installing Core 2026.9, I lost all my Sunsync Power Flow Cards, which were created in YAML and based on the Solarman integration. I received the message, “Incorrect configuration.” I saw that Modbus is now fully supported by this Core. Is there a migration process I need to perform? Thank you for your help, and please excuse my English; I’m using a translator.
There’s a lot of… Weirdness going on with 2026.9.0 your best shot is gather as much about your error as possible report it in the card owners github because that one is a HACS custom integration. There were fundamental changes that seem to have affected a lot of cards.
Then roll back to 2026.8.* until yoh have confirmation it works.
Thats said I used tk use that card and they’re very active I doubt it stays an issue for long if it still is one.
