Does Fronius Verto / Tauro / Symo / Primo (string) work locally with Home Assistant?

Yes, according to the public sources: the HA core integration “Fronius” talks to it over the local network and exposes settable entities, not only sensors; evcc supports it locally and lets evcc control it.

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.
