…g fixes - Rewrite GreenelyApi as a fully async httpx.AsyncClient client (fixes 'Blocking call to load_verify_locations in event loop') - Add Greenely Current Price sensor (MONETARY, SEK/kWh) for the Energy dashboard and automations - Fix config flow crash on unresolvable facility (fixes '500 Internal Server Error', adds CannotConnect handling) - Move price conversion to a single testable helper (prices.py) with consistent raw->SEK/kWh mapping - Make all sensors async, fix services JSON output bug - Bump to v2.2.0, add unit tests and API verification tool
homeassistant.const in HA 2026.7 does not export CURRENCY_EURO_CENT,
which caused ImportError -> setup_error when the sensor platform loaded.
Also drop reliance on CURRENCY_SWEDISH_KRONA for safety.
Use the explicit constant UNIT_SEK_PER_KWH ("SEK/kWh") instead.
Bump to v2.2.1.
Keep only tools/verify_greenely.py which is documented in the README. Temp websocket/REST debug scripts used during troubleshooting are not meant to ship in the integration.
Greenely now provides quarter-of-hour spot prices in the hourly spot-price
payload (quarters_prices: {quarter1..quarter4}). Adds a new MONETARY sensor
`sensor.greenely_current_quarter_price` exposing the current 15-minute price
in SEK/kWh, falling back to the hourly mean when a quarter is missing.
Verified against live data (e.g. 0.398 SEK/kWh for the current quarter vs
0.4048 hourly mean). Bump to v2.3.0.
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.

Summary
Adds a Nordpool/Tibber-compatible Greenely price sensor so an energy platform can use Greenely's real (VAT-inclusive) spot prices instead of Nordpool, without changing any logic.
New sensor:

tomorrow_valid: True, current price ~1.15 SEK/kWh. Unit tests pass (python3 tests/test_nordpool_format.py→ 3 passed).Design note
Kept as a separate feature commit on its own branch (off
feat/fix-and-modernize) so this is a single, gransknningsbar feature — separate from the earlier async-modernization work.
