Does Fronius Symo/Primo GEN24 (hybrid) work locally with Home Assistant?
Yes, according to the public sources: the HA core integration “Fronius” and the HACS integration “Fronius Modbus” talk to it over the local network and expose 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.
