Does Fox ESS T / S / F string inverters work locally with Home Assistant?

Yes, according to the public sources: the HACS integration “FoxESS - Modbus” and the HACS integration “FoxESS T Series” talk to it over the local network and expose settable entities, not only sensors.

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.
