Add PVForecastForecastSolar, a PV forecast provider for the free Forecast.Solar
API (https://forecast.solar), giving operators a no-account forecast source in
addition to Akkudoktor, VRM, Import and pvnode. An optional API key raises the
rate limit.
result.watts is the instantaneous AC power per timestamp, fed directly as
pvforecast_ac_power. Plants with several roof planes issue one request per plane
(Forecast.Solar is single-plane) and the powers are summed per timestamp.
Forecast.Solar azimuth (-180=N..0=S..90=W) is converted from EOS surface_azimuth
(north=0..south=180); local wall-clock timestamps are resolved via the response
timezone before resampling.
Registered in pvforecast.py and prediction.py. Adds tests for timezone
resolution, azimuth conversion, multi-plane summation and HTTP-error handling.
Add PVForecastPVNode, a native 15-minute PV forecast provider for the
pvnode.com V2 API, giving operators another forecast source to choose from
alongside Akkudoktor, VRM and Import.
Two request modes, selected by configuration:
* site_id set -> GET /v2/forecast/{site_id} (a saved, possibly calibrated
site managed on pvnode.com — the operator enters site id + API key)
* site_id empty -> POST /v2/forecast/inline (geometry sent inline from the
configured pvforecast.planes; no web-app setup required)
V2 response timestamps are site-local wall-clock accompanied by an IANA
timezone; they are resolved to absolute instants before EOS resamples them.
Nullable pv_power (e.g. at night) is treated as 0 W so the optimizer's linear
resampling does not interpolate phantom production across the night.
Registered in pvforecast.py (provider settings + id list) and prediction.py
(singleton, factory list, container union). Adds tests covering timezone
resolution, null handling, both request modes and HTTP-error propagation.
