# GridFit

> Does it work locally with Home Assistant and evcc — and does your grid operator list it? One database, two lenses: for each solar inverter, hybrid, home battery and wallbox, whether it works locally with Home Assistant (core and HACS) and evcc and can be controlled or only read, and which EU grid-connection lists (AT, BE, CZ, EE, NL, PL, SE read in full; 43 countries described) carry its models, with each list's own status, firmware and dates.

- 733 product families with a smart-home route, 14460 register models, 677 brands, checked 2026-10-31.
- An empty cell means "not found", never "does not work" or "not approved". Every row carries its source URL and the date it was seen.
- URLs: /local/ (family table), /grid/ (register model table), /grid/{cc}/ (one page per country), /{brand}/ (both lenses), /{brand}/{family}/ (device page), /{brand}/model/{code}/ (register model no family claims yet).
