feat(device): merge all entities into one shared device with station-type model

All entities (weather, battery, health, native Ecowitt) now report through a
single device under the existing {(DOMAIN,)} identifier, removing the separate
"Ecowitt {model}" device that appeared whenever Ecowitt was enabled. This
collapses the previous two-device layout (and the duplicate/untranslated native
Ecowitt sensors living on the second device) into one.

The device model reflects the running station type via _station_model():
"Ecowitt <model>" when Ecowitt is active (model learned from the payload's
`model` field and stored on runtime_data.ecowitt_model), else "WSLink", else
"PWS". Device identity is centralised in data.build_device_info() and reused by
every platform.

No device-registry migration is required: the identifier is unchanged; only the
model/grouping change. Full device unification under a renamed hub is deferred
to the rename round.

Tests: device-info assertions updated to the shared device across the entity
suites; new _station_model/build_device_info branch coverage in test_data.py;
received_ecowitt now asserts the learned model. 320 passed, 100% coverage.

+As of April 11, 2026, Ecowitt stations are supported in the pre-release version
+[v2.0.0pre1](https://github.com/schizza/SWS-12500-custom-component/releases/tag/v2.0.0pre1).
+You can download this pre-release in HACS under `target version`, where you can pick the exact
+version of the integration. Please be aware that this pre-release is really for testing
+purposes only.
 
-For stations that are using WSLink app to setup station and WSLink API for resending data (SWS 12500 manufactured in 2024 and later).

+---
+
+### Integration rename is planned for the next major release
+
+The current name no longer reflects what the integration does. It was initially developed
+primarily for the SWS 12500 station, but it already supports other weather stations as well
+(Bresser, Garni and others), and Ecowitt support is on the way — so the current name has
+become misleading. The transition will be announced via an update, and I'm also planning to
+offer a full data migration from the existing integration to the new one, so you won't lose
+any of your historical data.
+
+- The transition date hasn't been set yet, but it's currently expected to happen within the
+  next ~2–3 months. At the moment, I'm working on a full refactor and general code cleanup.
+  Looking further ahead, the goal is to have the integration fully incorporated into Home
+  Assistant as a native component — meaning it won't need to be installed via HACS but will
+  become part of the official Home Assistant distribution.
+
+- I'm also looking for someone who owns an Ecowitt weather station and would be willing to
+  help with testing the integration for these devices.

+
+## Warning — WSLink app (applies also to SWS 12500 with firmware > 3.0)
+
+Please read the **IMPORTANT** note below.
+
+For stations that use the WSLink app to set up the station and the WSLink API for resending
+data (also SWS 12500 stations manufactured in 2024 or later), you will need to install the
+[WSLink SSL proxy add-on](https://github.com/schizza/wslink-addon) into your Home Assistant
+— unless you are already running Home Assistant in SSL mode or you have your own SSL proxy
+in front of Home Assistant.
+
+---
+
+> [!IMPORTANT]
+> The recommendation above does not apply to all stations. As is known by now, some stations
+> — even when configured via the `WSLink App` — do not use the `WSLink protocol` to send
+> data to custom servers. It can therefore be confusing how to configure your station, and
+> for that case I made a simple debugging server (see below).
+
+## Not Sure How Your Station Sends Data?
+
+If you are struggling with configuration and don't know which protocol your station uses (`WSLink` or `PWS/WU`), or whether it sends data over SSL or plain HTTP — use our public test server:
+
+**<https://test-station.schizza.cz>**
+
+1. Open the link above and create a new session.
+2. Point your weather station to the generated subdomain address.
+3. Within a few seconds the server will show you:
+   - the **protocol** your station is using (`WSLink` or `PWS/WU`)
+   - whether the request arrived over **SSL** or **non-SSL**
+   - the full query string, headers, and payload your station sent
+
+This information tells you exactly how to configure the integration in Home Assistant.
+
+### Quick Recommendations
+
+| Station sends via | Protocol | Recommended Setup |
+|---|---|--- |
+| **plain HTTP** | PWS/WU | Point the station directly at Home Assistant — no proxy needed. Keep `WSLink API` unchecked (disabled). |
+| **plain HTTP** | WSLink | Point the station directly at Home Assistant — no proxy needed. Enable `WSLink API` in settings. |
+| **HTTPS (SSL)** | PWS/WU | Install the [WSLink Proxy Add-on](https://github.com/schizza/wslink-addon) — it terminates TLS and forwards plain HTTP to Home Assistant. Keep `WSLink API` unchecked (disabled). |
+| **HTTPS (SSL)** | WSLink | Install the [WSLink Proxy Add-on](https://github.com/schizza/wslink-addon) — it terminates TLS and forwards plain HTTP to Home Assistant, and enable `WSLink API`. |
+
+— If the test server shows your station is sending over SSL, you need the [WSLink Proxy Add-on](https://github.com/schizza/wslink-addon). If it sends plain HTTP, you can connect directly.

 ## Requirements
 
 - Weather station that supports sending data to custom server in their API [(list of supported stations.)](#list-of-supported-stations)
 - Configure station to send data directly to Home Assistant.
 - If you want to push data to Windy, you have to create an account at [Windy](https://stations.windy.com).

+- Bresser stations that support custom server upload — [this model is known to work](https://www.bresser.com/p/bresser-wi-fi-clearview-weather-station-with-7-in-1-sensor-7002586), for example
+- Garni stations with WSLink support or custom server support
+- and a bunch of other models that aren't listed here are also supported
+
+## Supported sensors
+
+The integration auto-creates sensors as soon as the station first sends data for them — new
+sensors trigger a notification in Home Assistant and are added to the entity list
+automatically.
+
+Beyond the standard set (outdoor / indoor temperature and humidity, barometric pressure,
+wind speed / direction / gust, rain rate and daily / weekly / monthly / yearly totals, dew
+point, UV index, solar irradiance) the WSLink protocol also exposes:
+
+- additional channels **CH2** and **CH3** for temperature and humidity
+- **WBGT** index, **heat index**, **wind chill**
+- sensor battery levels (outdoor, indoor, CH2)
+- **Formaldehyde (HCHO)** in ppb and **VOC level** as a 1–5 air-quality index
+  (1 = worst, 5 = best) from the WH46 / 7-in-1 air-quality combo sensor
+- **HCHO/VOC sensor battery** reported as a percentage
+
+HCHO / VOC entities are only created when the station reports the air-quality module as
+connected (`t9cn = 1`), so they don't clutter the device when no such sensor is attached.
 
 ## Installation

+"""Sencor SWS 12500 Weather Station integration (push/webhook based).
 
+Architecture overview
+---------------------
+This integration is *push-based*: the weather station calls our HTTP endpoint and we
+receive a query payload. We do not poll the station.
+
+Key building blocks:
+- `WeatherDataUpdateCoordinator` acts as an in-memory "data bus" for the latest payload.
+  On each webhook request we call `async_set_updated_data(...)` and all `CoordinatorEntity`
+  sensors get notified and update their states.
+- `hass.data[DOMAIN][entry_id]` is a per-entry *dict* that stores runtime state
+  (coordinator instance, options snapshot, and sensor platform callbacks). Keeping this
+  structure consistent is critical; mixing different value types under the same key can
+  break listener wiring and make the UI appear "frozen".
+
+Auto-discovery
+--------------
+When the station starts sending a new field, we:
+1) persist the new sensor key into options (`SENSORS_TO_LOAD`)
+2) dynamically add the new entity through the sensor platform (without reloading)
+
+Why avoid reload?
+Reloading a config entry unloads platforms temporarily, which removes coordinator listeners.
+With a high-frequency push source (webhook), a reload at the wrong moment can lead to a
+period where no entities are subscribed, causing stale states until another full reload/restart.

+Why this dispatcher exists
+--------------------------
+Home Assistant registers aiohttp routes on startup. Re-registering or removing routes at runtime
+is awkward and error-prone (and can raise if routes already exist). This integration supports two
+different push endpoints (legacy WU-style vs WSLink). To allow switching between them without
+touching the aiohttp router, we register both routes once and use this in-process dispatcher to
+decide which one is currently enabled.
 
-from aiohttp.web import AbstractRoute, Response
+Important note:
+- Each route stores a *bound method* handler (e.g. `coordinator.received_data`). That means the
+  route points to a specific coordinator instance. When the integration reloads, we must keep the
+  same coordinator instance or update the stored handler accordingly. Otherwise requests may go to
+  an old coordinator while entities listen to a new one (result: UI appears "frozen").

+This module contains small helpers used across the integration.

+Notable responsibilities:
+- Payload remapping: convert raw station/webhook field names into stable internal keys.
+- Auto-discovery helpers: detect new payload fields that are not enabled yet and persist them
+  to config entry options so sensors can be created dynamically.
+- Formatting/conversion helpers (wind direction text, battery mapping, temperature conversions).
+
+Keeping these concerns in one place avoids duplicating logic in the webhook handler and entity code.

+These tests exercise the runtime health model end to end without requiring real

+  A `MockConfigEntry` supports that, so we always pass one.
+- Health persistence writes `config.runtime_data.health_data`; we set
