Does APsystems DS3 / QS1 / QT2 / YC microinverters work locally with Home Assistant?

Yes, according to the public sources: the HA core integration “APsystems”, the HACS integration “APsystems ECU Reader” (+1 more) 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.
