Does Fox ESS H1 / AC1 / AIO-H1 (single-phase) work locally with Home Assistant?

Yes, according to the public sources: the HACS integration “FoxESS - Modbus” talks to it over the local network and exposes settable entities, not only sensors; evcc supports it locally for metering.

Firmware updates can open or close local access — check the integration's own page before you buy, and your installer before software changes export limits or charges a battery from the grid.
