Adds a new MONETARY sensor (Greenely Nord Pool Price) that exposes Greenely's
real spot prices — including 15-minute quarter prices — in the same attribute
format as the popular Nordpool custom component and the Tibber price sensor.
An energy platform can point its EV charging / arbitrage logic from `nordpool`
or `tibber` to this sensor without changing any logic.
Exposed attributes:
- today / tomorrow and raw_today / raw_tomorrow as 96 x 15-minute [ts, price] points
- current_price, min, max, mean, average
- off_peak_1 / peak / off_peak_2 (Nordpool fixed blocks)
- low_price, price_percent_to_average, tomorrow_valid
- Tibber-style price_level (LOW/NORMAL/HIGH) and intraday_price_ranking
Implementation:
- New pure-Python module nordpool_format.py (no HA import) that expands each
hourly entry's quarters_prices {q1..q4} into 15-minute points, with fallback
to the hourly mean when a quarter is missing. Unit-testable standalone.
- Verified against live Greenely data (current 1.15 SEK/kWh, 96 pts today and
tomorrow, tomorrow_valid true) and an on-file unit test.
Bump to v2.4.0.
SEMP Meter (Solar Energy Management) parses the day-ahead curve from
today/tomorrow/raw_today/raw_tomorrow attributes and only accepts list
items that are DICTS with a "start" ISO timestamp and a "value" price
key (tariff_provider._read_prices_list). The previous tuple-pair format
([ts, price]) was silently dropped by SEM, leaving its battery/EV
planning with an empty curve and a fallback constant price.
Change build_price_series to emit each 15-min point as
{"start": "<ISO>", "value": <SEK/kWh>} for today/tomorrow and
raw_today/raw_tomorrow, keeping all other fields (current_price,
min/max/mean/average, off_peak_1/peak/off_peak_2, low_price,
price_percent_to_average, tomorrow_valid, price_level,
intraday_price_ranking) unchanged.
Now both the current-price read (state) and the full day-ahead curve
(attributes) feed SEM directly from the Greenely sensor.
Verified with a concept-proof replaying SEM's exact dict-parse logic
against the emitted attributes: 96/96 today + 96/96 raw_today points
parsed, sorted, timestamps ISO-valid.
Bump manifest to 2.4.1.

Greenely Nord Pool Price sensor — SEM-kompatibel (Solar Energy Management)
En ny
Greenely Nord Pool Price-sensor som låter dig driva SEM (Solar Energy Management)direkt på Greenelys riktiga spotpriser — ingen Nordpool-/Tibber-integration behövs.
🎯 Varför den här PR:en (SEM-fix)
Patriks HA kör SEM (
traktore-org/sem-community) för batteri-toppning/EV-laddning på spotpris.SEM får priskurvan från sensorns
today/tomorrow-attribut, men accepterar bara dict-element(
{"start": <ISO>, "value": <pris>}) — alla andra format ignoreras tyst.Den här PR:en:
GreenelyNordpoolPriceSensorsom bygger 96-punkts (15-min) dag-/imorgonkruvor frånGreenelys
spot-price+quarters_prices.start+value) förtoday/tomorrow/raw_today/raw_tomorrow— så SEM direkt kan konsumera den som dynamisk tariff/priskälla.native_value= aktuellt pris SEK/kWh (läses av SEM som nutidspris frånstate).✅ Verifierat
