Does Kostal PIKO (string) work locally with Home Assistant?

Yes, according to the public sources: the HA core integration “Kostal Plenticore Solar Inverter” and the HACS integration “Kostal Piko Solar Monitor” talk to it over the local network and expose 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.
