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.

Grid-connection lists

The list is the authority; this is a cross-reference.

Is the SMA Sunny Boy Storage on an EU grid-connection list?

Yes — models of this family are on the lists of AT, BE, EE, NL (lists dated up to 2026-10-30, read 2026-10-31); the other 3 of the 7 lists read have no matching model, which is not a “no”.

The other 36 countries: a battery there

No model rows for these: they publish no usable list, or GridFit has not read it. Each gets one answer by the same rule as the grid view — the maker's own document first, then the country's type-A ceiling, then what the lists read say.

Likely fit: the maker's document names the country (1)

Italy

SMA's own document names these countries — the grid operator still decides at the application.

On 4 EU lists (AT, BE, EE, NL): the maker has had the model certified and 4 grid operators accept it. Nothing is checked in these countries themselves: where there is no list the grid operator reads the maker's certificate for that country — ask the maker or installer for it; where a list exists that GridFit has not read, check the model there.
