Does SMA Sunny Boy Storage work locally with Home Assistant?
Yes, according to the public sources: the HA core integration “SMA Solar” and the HACS integration “SMA Devices Plus” talk to it over the local network, read-only as far as we can tell; 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.
