v1.7.0

Added

• Wind Chill (0x04) and Heat Index (0x05): Both common_list hex IDs are now exposed as temperature entities (°C) for all outdoor weather stations that emit them (WH69, WH90, WS90, WH80/WS80). These were silently dropped before because they had no SENSOR_TYPES entry or device key list. (issues #170, #171)
• UV Radiation (0x16): Raw UV irradiance in µW/m² is now a separate entity, distinct from the existing UV Index (0x17). Added to all outdoor weather stations that have a UV sensor. (issue #160)
• Total Rain (0x14): All-time cumulative rain total is now exposed for rain-capable devices (WH69, WH90, WS90, WH85, WH40). (issue #161)
• Indoor sensors via common_list (0x01, 0x06, 0x08, 0x09): Gateways running newer firmware may emit indoor temperature, indoor humidity, absolute pressure, and relative pressure via common_list hex IDs instead of (or in addition to) the wh25 block. These IDs are now in the WH25 device key list and SENSOR_TYPES so they create proper entities when present. (issue #172)
• WH45/WH46D AQI index entities for co2 block: All AQI index fields from the co2 livedata block are now exposed — PM25_RealAQI, PM25_24HAQI, PM10_RealAQI, PM10_24HAQI, PM1_RealAQI, PM1_24HAQI (WH46D), PM4_RealAQI, PM4_24HAQI (WH46D) — each as a dimensionless AQI entity. Previously only raw concentrations (µg/m³) were exposed for the co2 block. (issue #163)
• Solar Illuminance (lx) entity for non-hex weather stations (WH68): The hex-based path (0x15 W/m²) already computed a solar_lux illuminance entity, but the string-key path (solarradiation W/m², used by WH68 and similar) did not. It now does the same calculation (W/m² × 126.7). (issue #180)

Fixed

• Solar Radiation shows in lx instead of W/m² (gateway in lux mode): When a WH68-type gateway is configured to output solar radiation in lux, the integration labelled the entity "Solar Radiation" with a lux unit — visually wrong. The entity is now renamed "Solar Illuminance" (lx, illuminance device class) and a derived "Solar Radiation" entity in W/m² (÷ 126.7) is also created alongside it. (issue #180)
• WH68 detection falls back to "Solar & Wind" firmware name: If a gateway reports img: "" or a non-standard string for WH68, the official firmware name string "Solar & Wind" is now accepted as a detection fallback, matching the hardening pattern used for WH90. (issue #166)
• WH45 detection falls back to "PM25 & PM10 & CO2" firmware name: Same hardening for WH45/WH46D — the official firmware name string "PM25 & PM10 & CO2" is now a valid detection fallback. (issue #167)

Changed

• 0x0F Rain Gain intentionally omitted: A comment has been added in coordinator.py near the rain block to document that 0x0F (ITEM_RAIN_GAIN) is a calibration multiplier and is intentionally not exposed as a sensor entity. Use the gateway's web UI or the get_rain_totals endpoint to view or change the gain. (issue #168)
