Does Fronius Wattpilot work locally with Home Assistant?
Yes, according to the public sources: the HACS integration “Fronius Wattpilot” and the HACS integration “go-e APIv2 Connect” talk to it over the local network and expose settable entities, not only sensors; evcc supports it locally and lets evcc control it (needs an evcc sponsor token).
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 Fronius Wattpilot on an EU grid-connection list?
Yes — models of this family are on the list of AT (lists dated up to 2026-10-30, read 2026-10-31); the other 6 of the 7 lists read have no matching model, which is not a “no”.

The other 36 countries: a wallbox 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.

No list and no model-level rule for this kind of device: nothing to approve, so the model is fit here as far as a list goes.
- Possibly fit: accepted on other EU lists (10)

On 1 EU list (AT): the maker has had the model certified and one grid operator accepts 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.
