Does Alpha ESS SMILE / Storion work locally with Home Assistant?

Yes, according to the public sources: the HACS integration “AlphaESS Modbus TCP” 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.

Grid-connection lists

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

Is the Alpha ESS SMILE / Storion on an EU grid-connection list?

Yes — models of this family are on the lists of AT, BE, CZ, EE, NL, SE (lists dated up to 2026-10-30, read 2026-10-31); the other 1 of the 7 lists read have no matching model, which is not a “no”.

The other 36 countries: a hybrid inverter 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.

Possibly fit: accepted on other EU lists (24)

Bosnia and Herzegovina?SwitzerlandCyprusGermanysDenmark?FinlandFrancesGreat BritainGreecesCroatiasHungaryIrelandItalysLiechtenstein?LithuaniaLuxembourgMoldova?Northern Ireland?NorwayPortugalRomania?SloveniasSlovakiaTürkiye?

On 6 EU lists (AT, BE, CZ, EE, NL, SE): the maker has had the model certified and 6 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.

Other procedure: over the type-A limit (1)

Spain

Above the type-A ceiling (100 kW in Spain): type B, a procedure of its own — conformity per installation, not a certificate per model.

Unknown: not confirmed (11)

Whether a list or a rule applies is not confirmed yet.

s = from search results, ? = unverified; without a mark the country page was opened. The state per country comes from the EU+ grid-connection table; each country page says more.
