1.2.0 - six new providers

The first stable 1.2.x release.

Requirements: Home Assistant 2026.9 or newer. If you run an older Home Assistant, stay on the 1.1.8 tag.

It adds six providers to one integration, on top of the 1.2.0-beta.1 foundation (Home Assistant 2026.9 compatibility, the repaired Netz Niederösterreich login, brand images):

• energiedaten.at - an API platform that republishes Austrian smart meter data. Configured with an API key; its 15-minute interval readings are summed up per local day.
• energyLIVE (smartENERGY) - meter reader hardware with an API key, reporting cumulative meter readings (1.8.0/2.8.0) and the current power in W.
• DSMR / P1 customer interface - the meter's own interface, read over a serial cable or a network P1 reader, encrypted meters included (twelve DSMR dialects, among them the Austrian Sagemcom T210-D-R).
• aWATTar market prices - the public EPEX day-ahead feed of Austria and Germany in ct/kWh, which is what makes load shifting automatable. No account required.
• Selectra tariff planning - the tariff a household actually pays, with its time bands and its feed-in price. Commercial API with a personal token and a free tier of 60 calls per month, which the adapter spends carefully.
• Salzburg Netz - the grid operator's own POST-only interface with 15-minute load profiles, read with an API key from the service portal plus the customer number. One request per metering point per day.

On verification: the APIs that could not be checked against a live service (energiedaten.at, Selectra, Salzburg Netz) say so in their section of the README. Selectra and Salzburg Netz were written against published specifications, and Salzburg Netz reads records tolerantly because the shape of its JSON response is not documented.
