fix(P4): Panel-Bringup meldet Fehler im Klartext statt abzustürzen (1.6.2)

Ein fehlgeschlagener Panel-Aufbau endete bisher in einem ESP_ERROR_CHECK
tief im LVGL-Port und damit in einem Speicherauszug ohne erkennbare Ursache.

- Die Schritte des Waveshare-Bringups melden ihren Fehler über esp_rom_printf,
  also auch bei Core-Debug-Level "none". Zusätzlich werden PSRAM-Größe,
  freier PSRAM, größter freier Block und der Framebuffer-Bedarf ausgegeben.
- jc_board_bringup() liefert jetzt einen Status. Kommt das Panel nicht hoch,
  bleibt die Firmware ohne Anzeige lauffähig (UART + OTA), statt beim ersten
  LVGL-Zugriff erneut abzustürzen.
- ui.cpp: alle öffentlichen Funktionen prüfen, ob ui_init gelaufen ist.
- Fehlerbehebung: esp_lcd_touch_new_i2c_gt911 setzt im Fehlerfall einen bereits
  freigegebenen Zeiger. Das Handle wird vorbelegt und der Rückgabewert geprüft.

+Version 5.6.3:
+- Bug-Fix: Beim Aufwecken über das Touch-Display blieb die Auswahl „Espresso oder Cold Extraction"
+  manchmal aus, während sie über den Schalter kam. Ursache waren zwei unterschiedliche Bedingungen für
+  ein und dieselbe Sache: Das Display prüfte zum ANZEIGEN der Auswahl zusätzlich, ob der Modus gerade
+  scharfschaltbar ist (cxArmable) - zum UNTERDRÜCKEN der Rückfrage der S3 („wakeEspresso") aber nicht.
+  Fiel diese Bedingung weg, zeigte der Dialog nur noch „Aufwecken", schloss aber trotzdem das
+  Auswahlfenster der S3: Die Frage war auf beiden Seiten weg. Der Schalterweg hatte diese Lücke nie,
+  weil er allein an der S3 hängt. Behoben in der Display-Firmware 1.4.2.
+- Diagnose: /Cold-Extraction zeigt jetzt zusätzlich zum Live-Stand der Voraussetzungen auch das
+  LETZTE Aufwecken - über welchen Weg (Schalter/Timer/Web oder Display, dort mit getroffener Wahl)
+  und mit welchem Ergebnis (Fenster geöffnet, am Display bereits entschieden, Abfrage aus, kein
+  Display verbunden, Wartung/Reinigung/Tuning aktiv, nicht freigeschaltet). Hintergrund: Die
+  Live-Liste zeigt nur den jetzigen Stand - blieb die Frage aus, hatte sich die Lage bis zum
+  Nachsehen längst wieder geändert, und der Grund war nicht mehr zu ermitteln.
+- Die Entscheidung über das Auswahlfenster ist als Bedingungskette geschrieben, damit jeder Zweig
+  seinen Grund hinterlässt (vorher eine einzige verknüpfte Bedingung ohne Rückmeldung).
+
+Version 5.6.2:
+- Bug-Fix: Die Abfrage beim Aufwecken erschien nicht, sobald der Cold-Extraction-Modus noch aktiv war -
+  und da er persistent ist, war er das nach dem ersten kalten Bezug dauerhaft. Die Bedingung „Modus ist
+  aus" war falsch gedacht („sonst gibt es nichts zu fragen"): Die Auswahl muss in BEIDE Richtungen gehen,
+  also auch von kalt zurück auf Espresso. Ohne das hing man nach dem ersten kalten Bezug im kalten Modus
+  fest, ohne beim Aufwecken je wieder gefragt zu werden.
+- „Espresso" beendet jetzt einen laufenden Cold-Extraction-Modus, statt ihn nur nicht einzuschalten.
+  Sonst wäre die Auswahl eine Einbahnstraße gewesen.
+- Das Auswahlfenster bleibt bei aktivem Modus offen (bisher wurde es sofort geschlossen); die Frage
+  lautet dann „weiter kalt oder zurück auf Espresso?".
+- Die Diagnose auf /Cold-Extraction listet den Modus nicht mehr als Voraussetzung, sondern zeigt ihn
+  als Ist-Zustand an.
+
+Version 5.6.1:
+- Diagnose: Die Seite /Cold-Extraction zeigt jetzt live, welche Voraussetzungen der Abfrage beim
+  Aufwecken erfüllt sind (freigeschaltet, Abfrage eingeschaltet, Touch-Display verbunden, Modus
+  gerade aus, kein Wartungsmodus/Reinigung/Tuning) und ob das Auswahlfenster gerade offen ist.
+  Hintergrund: Die Abfrage hängt an fünf Bedingungen gleichzeitig - fehlt eine, passiert einfach
+  nichts, und es war von außen nicht erkennbar welche.
+- Die Abfrage kommt jetzt auch nach einem Kaltstart, nicht nur nach dem Standby. Wer die Maschine
+  am Netzschalter einschaltet, durchläuft nie einen Standby-Übergang; dieser Weg war deshalb bisher
+  nicht abgedeckt. Startet die Maschine in den Standby hinein, bleibt es beim Standby-Übergang.
+
+Version 5.6.0:
+- Die Abfrage „Espresso oder Cold Extraction" kommt jetzt bei JEDEM Weg aus dem Standby, also auch beim
+  Aufwecken über den Schalter. Bisher war sie eine reine Vorab-Abfrage des Touch-Displays und erschien nur
+  beim Antippen des Standby-Bildschirms - beim Schalter ist der Standby aber schon beendet, bevor das
+  Display überhaupt fragen könnte. Dieser Weg war damit nie abgedeckt.
+- Dafür hält die Steuerung nach dem Aufwecken ein Auswahlfenster offen (20 s): Der Wasserkreis heizt in
+  dieser Zeit nicht, das Display zeigt die Auswahl mit Countdown. Ohne Entscheidung wird anschließend
+  normal geheizt - es geht also nichts verloren, wenn niemand hinsieht.
+- Das Fenster öffnet nur mit angeschlossenem Touch-Display (ohne Display könnte niemand wählen), bei
+  freigeschalteter Funktion und aktivierter Einstellung „Abfrage beim Aufwecken", und nur wenn der
+  Cold-Extraction-Modus nicht ohnehin schon aktiv ist. Es schließt sofort bei einer Entscheidung, bei
+  Bezug/Spülen oder erneutem Standby.
+- Neue Aktion „wakeEspresso": beendet den Standby (falls noch aktiv) und schließt das Auswahlfenster.
+  Das Display sendet sie statt „deactivateStandby", sobald die Auswahl relevant ist - sonst würde nach
+  dem Aufwecken über den Dialog gleich nochmal gefragt.
+- Neue State-Felder „cxWakeChoice" (Fenster offen) und „cxWakeChoiceSec" (Restsekunden).
+
 Version 5.5.0:
 - Neu: Beim Aufwecken aus dem Standby fragt das Touch-Display, ob normal geheizt (Espresso) oder kalt
   extrahiert werden soll. Damit lässt sich das bei jedem Aufwecken neu entscheiden, ohne vorher die

-# JC4880P443C-I-W — Touch-Display-Firmware (ESP32-P4)
-
-Client-Firmware für das Guition-Smart-Display **JC4880P443C-I-W**, die als
-UART-Touch-Bedienung für die Dual-PID-Siebträgersteuerung dient.
-
-Die **Hauptplatine (ESP32-S3, `Dual_PID_FastHeatUp.ino`)** bleibt die Steuerzentrale
-inkl. WLAN/Webinterface. Dieses Display ist ein **reiner UART-Client**: es empfängt den
-Zustand und sendet Bedienkommandos. Protokoll: siehe
-[`../Doku/JC-Display_UART-Protokoll.md`](../Doku/JC-Display_UART-Protokoll.md).
-
-## Hardware (laut Vendor-Paket im Ordner `JC4880P443C_I_W/`)
-
-| Komponente | Bauteil / Pin |
-|---|---|
-| Haupt-MCU (UI) | ESP32-P4 |
-| WLAN/BT (hier ungenutzt) | ESP32-C6 |
-| Display | ST7701, 480×800 IPS, **MIPI-DSI** |
-| Touch | GT911, I²C **SDA=GPIO7 / SCL=GPIO8** |
-| Backlight | **GPIO23** (LEDC-PWM) · LCD-Reset **GPIO5** |
-| Freie Expansion-IO (JP1) | GPIO 52/51/50/49/35/34/33/32/31/30/29/28, ES_I2C, +3V3/+5V/GND |
-
-## Verkabelung zur Hauptplatine (UART, gekreuzt)
-
-Pins aus dem Expand-IO-Header **JP1** (Schaltplan `JC4880P443C_I_W/5-Schematic/4_USB&IO.png`):
-
-```
-  S3 GPIO43 (TX) ----> P4 GPIO31 (RX)     (DISPLAY_UART_RX_PIN)
-  S3 GPIO44 (RX) <---- P4 GPIO33 (TX)     (DISPLAY_UART_TX_PIN)
-  S3 GND        ------ P4 GND
-```
-> Die rechte JP1-Spalte (`C6_U01TXD`/`C6_I10RXD`/…) gehört zum **ESP32-C6** — nicht
-> verwenden. 3,3-V-Logik beidseitig → keine Pegelwandlung nötig.
-
-## Projektstruktur (eigener Code)
-
-| Datei | Zweck |
-|---|---|
-| `JC_Display_Firmware.ino` | setup()/loop(), verdrahtet die Module |
-| `config.h` | Pins, UART, Protokoll-Parameter |
-| `machine_state.h` | Spiegel des `state`-Objekts der S3 |
-| `protocol_client.h/.cpp` | UART-Protokoll: hello/state/ack/profiles/… + Heartbeat |
-| `ui.h/.cpp` | LVGL-Dashboard (hardwareunabhängig) |
-| `display_hal.h/.cpp` | LVGL-/UI-Verdrahtung + Lock-Wrapper |
-| `board_bringup.c` | esp_lcd-Hardware-Bringup (C; nur bei `JC_USE_REAL_PANEL=1`) |
-
-## Abhängigkeiten
-
-- **Arduino-ESP32** ≥ 3.1 (mit ESP32-P4-Support), Board: *ESP32P4 Dev Module*,
-  **PSRAM aktiviert**.
-- **LVGL** 9.x + `lv_conf.h`. Tipp: die `lv_conf.h` aus dem Vendor-Beispiel
-  (`JC4880P443C_I_W/1-Demo/arduino_examples/lvgl_v9_sw_rotation/lv_conf.h`) übernehmen
-  und `LV_FONT_MONTSERRAT_40` aktivieren (große Temperaturanzeige).
-- **ArduinoJson** 7.x.
-
-## Zwei Betriebsmodi (`JC_USE_REAL_PANEL` in `display_hal.h`)
-
-### `0` = Stub-Modus (Standard)
-Kompiliert **ohne** Display-Treiber (eigenes Minimal-LVGL, rendert ins Leere). Ideal, um
-**Protokoll/UART/Logik** am Schreibtisch zu testen (Debug über USB-CDC `Serial`). Läuft auf
-jedem ESP32 mit LVGL+ArduinoJson.
-
-### `1` = echte Hardware (Hersteller-BSP)
-`display_hal.cpp` baut auf der **erprobten Hersteller-Portierung** auf. Dazu folgende
-Dateien aus `JC4880P443C_I_W/1-Demo/arduino_examples/lvgl_v9_sw_rotation/` **in diesen
-Sketch-Ordner kopieren**:
-
-```
-pins_config.h
-lvgl_port_v9.h
-lvgl_port_v9.c
-src/lcd/      (komplett: esp_lcd_st7701*.c/.h, st7701_lcd.*)
-src/touch/    (komplett: esp_lcd_touch*.c/.h, gt911_touch.*)
-```
-
-Der Init-Ablauf (MIPI-DSI-PHY-LDO, ST7701, GT911, LEDC-Backlight, `lvgl_port_init`) ist
-1:1 aus dem Vendor-Beispiel `lvgl_sw_rotation.c` übernommen — nur der Demo-Aufruf
-(`lv_demo_widgets()`) wurde durch `ui_init()` ersetzt.
-
-**Wichtig:** Im realen Modus läuft LVGL in einem **eigenen FreeRTOS-Task**. UI-Zugriffe aus
-der Arduino-`loop()` (z. B. `ui_update` bei jedem state-Push) sind daher in
-`hal_lock()/hal_unlock()` (= `lvgl_port_lock/unlock`) gekapselt — ist in der `.ino`
-bereits umgesetzt.
-
-### Ausrichtung
-Das Vendor-Beispiel nutzt **90° (Querformat 800×480)**. Das hiesige Dashboard ist für
-**Hochformat 480×800** ausgelegt → in `pins_config.h`
-`EXAMPLE_LVGL_PORT_ROTATION_DEGREE_` auf **0** setzen (oder das UI-Layout in `ui.cpp` auf
-Querformat anpassen).
-
-## Status
-
-**Fertig & hardwareunabhängig:**
-- Vollständiger UART-Protokoll-Client (v2): hello-Handshake, state-Parsing, ack/error,
-  Profile, Heartbeat, Link-Timeout.
-- Dashboard: Live-Temperaturen Wasser/Dampf (ist/soll), Duty-Balken, Status-Banner
-  (Farbe nach `statusKey`), Verbindungs- & WLAN-Anzeige, Bezugs-Timer, Bedien-Buttons.
-- Senden für `setPid`, `startAutotune`/`stopAutotune`, `getProfileDetails` vorhanden.
-
-**Board-Bringup:** auf die konkreten JC-Pins/Treiber gesetzt (ST7701/GT911, Backlight,
-I²C) — sobald die BSP-Dateien kopiert und `JC_USE_REAL_PANEL=1` gesetzt ist, lauffähig.
-
-**Noch offen (UI-Ausbau):** weitere Screens — Einstellungen (Brew/Service/Sensor),
-Profil-Auswahl/-Editor, PID/AutoTune-Bedienung.
-
-## Inbetriebnahme / Fehlersuche (Lessons learned)
-
-- **Stromversorgung:** Jedes Board **eigene** Versorgung. Zwischen P4 und S3 nur
-  **GND + TX + RX** — **kein** 3V3/5V! Den S3 nicht über den 3V3-Header des Displays
-  speisen (reicht nicht / Regler-Rückspeisung).
-- **Pins nach Silkscreen:** Die UART-Pads am Board nach Aufdruck **`GPIO50`/`GPIO51`**
-  identifizieren, nicht nach Header-Pin-Nummern.
-- **S3-Seite:** muss mit `TOUCH_UART_ENABLED 1` geflasht sein und laufen. Da `Serial`
-  (Debug) und der Touch-UART beide auf GPIO43/44 liegen, ggf. **„USB CDC On Boot:
-  Enabled"** verwenden, damit der Debug-Port nicht die UART-Pins blockiert.
-
-### Diagnose-Schalter (in `config.h`)
-
-- `SHOW_DEBUG_OVERLAY 1` → blendet unten ein grünes Panel ein: gesendete `hello`,
-  empfangene Bytes/Zeilen, Parse-Fehler, letzte Rohzeile, Link-Status.
-- `UART_SELFTEST_INTERNAL_LOOPBACK 1` → legt TX chip-intern auf RX (ohne Draht/Pins).
-  Läuft „RX byte" hoch, sind Firmware+UART ok → Problem liegt an Pins/Verkabelung.
-  **Nach dem Test wieder auf 0!**

P4_Display_Firmware/Changelog.txt

@@ -1,3 +1,104 @@
+Version 1.6.2:
+- Kommt das Panel nicht hoch, stürzt der P4 nicht mehr wortlos ab. Die Bringup-Schritte
+  melden ihren Fehler jetzt im Klartext auf der seriellen Konsole (auch bei abgeschaltetem
+  Core-Debug-Level), zusammen mit PSRAM-Größe, freiem PSRAM und dem tatsächlich benötigten
+  Framebuffer-Bedarf. Vorher endete ein fehlgeschlagener Panel-Aufbau in einem
+  Speicherauszug, aus dem die Ursache nicht hervorging.
+- Schlägt der Panel-Aufbau fehl, läuft die Firmware ohne Anzeige weiter, statt ein zweites
+  Mal abzustürzen: UART-Verbindung und OTA bleiben offen, die S3 kann also neu flashen.
+  Alle Oberflächenfunktionen prüfen dafür, ob das Dashboard überhaupt aufgebaut wurde.
+- Fehlerbehebung: Findet der Touch-Controller nicht statt, lieferte der Hersteller-Treiber
+  einen bereits freigegebenen Zeiger zurück, der ungeprüft weiterverwendet wurde. Das
+  Display läuft in diesem Fall jetzt einfach ohne Bedienung weiter.
+
+Version 1.6.1:
+- Waveshare 7" (H): Bild und Touch lassen sich um 180 Grad drehen, wenn das Panel auf dem
+  Kopf eingebaut ist. Schalter WS7_ROTATE_180 in pins_config.h, Vorgabe ist gedreht.
+  Die Drehung übernimmt der PPA-Grafikbeschleuniger des ESP32-P4 - die Software-Rotation
+  des LVGL-Ports rechnet nur in RGB565 und wäre für dieses Panel unbrauchbar.
+- Der Touch dreht mit, sonst läge die Bedienung spiegelbildlich zum Bild.
+
+Version 1.6.0:
+- Neu: Dieselbe Firmware läuft jetzt auch auf einem Waveshare ESP32-P4-Pico mit dem
+  Waveshare 7inch DSI LCD (H) (1280x720). Umgeschaltet wird über „JC_PANEL_TYPE" in
+  config.h; WS_PANEL_7H ist ab dieser Version die Vorgabe, JC_PANEL_43 und JC_PANEL_70
+  bleiben unverändert verfügbar.
+- Das Waveshare-Panel hängt hinter einer Bridge, die ausschließlich RGB888 annimmt. LVGL
+  rechnet für dieses Panel deshalb mit 24 statt 16 Bit Farbtiefe. lv_conf.h liest dazu
+  JC_PANEL_TYPE aus config.h, damit Sketch und LVGL-Bibliothek garantiert dieselbe
+  Farbtiefe benutzen; display_hal.cpp bricht den Build ab, falls sie auseinanderlaufen.
+  Der Panelwechsel muss aus diesem Grund in config.h erfolgen und nicht per Compiler-Flag.
+- Bringup ohne Hersteller-Panel-Treiber: DSI-Bus, Kommandokanal und DPI-Panel werden direkt
+  angelegt. Entscheidend ist die Legacy-Referenztaktquelle PLL_F20M - mit der Standardquelle
+  bleibt der Bildschirm auf ESP32-P4 Rev. 1.3 / ECO2 schwarz. Die Zeitbasis (2 Lanes zu
+  1250 Mbit/s, 80 MHz DPI-Takt, Austastlücken 64/64/64, rund 60 Hz) steht als WS7_*-Werte
+  in pins_config.h und ist dort anpassbar, falls das Bild reißt.
+- Panel-Freigabe und Helligkeit laufen beim Waveshare nicht über einen PWM-Pin, sondern über
+  Register der Bridge auf I2C-Adresse 0x45. Die Hintergrundbeleuchtung wird bewusst erst
+  eingeschaltet, wenn die DSI-Ausgabe steht - sonst blitzt beim Start Bildrauschen auf.
+  Standby-Abdunklung und „Uhrzeit im Standby" funktionieren wie bei den JC-Panels.
+- Touch: Der GT9271 des Waveshare-Panels benutzt dieselbe Registerbelegung wie der GT911,
+  liegt aber auf I2C-Adresse 0x14 und meldet im Hochformat. X und Y werden deshalb getauscht
+  und auf die Bildfläche begrenzt; Ausreißer des Controllers landen nicht mehr als Klick am
+  Bildrand. Sollte die Bedienung spiegelverkehrt reagieren, lässt sich das mit
+  WS7_TOUCH_MIRROR_RAW_X / _Y in pins_config.h umdrehen.
+- Der Framebuffer wächst auf 3 x 2,8 MB (rund 8,3 MB PSRAM). Auf dem P4-Pico mit 32 MB
+  PSRAM ist das unkritisch.
+- Die UART-Pins zur Hauptplatine sind für das Waveshare-Board getrennt eingestellt, weil
+  dessen 40-poliger Header eine andere Belegung hat als die JC-Panels: TX = GPIO17,
+  RX = GPIO18 (JC-Panels unverändert TX = GPIO33, RX = GPIO31).
+
+Version 1.5.0:
+- Neu: Dieselbe Firmware unterstützt jetzt auch das 7-Zoll-Display Guition JC1060P470C-I-W
+  (JD9165, 1024x600) zusätzlich zum bisherigen 4,3-Zöller JC4880P443C-I-W (ST7701, 480x800).
+  Umgeschaltet wird über „JC_PANEL_TYPE" in config.h (JC_PANEL_43 / JC_PANEL_70) oder per
+  Compiler-Flag -DJC_PANEL_TYPE=70. Vorgabe bleibt das 4,3-Zoll-Panel, dessen Verhalten sich
+  nicht ändert.
+- Panel-Treiber esp_lcd_jd9165.c/.h aus dem Hersteller-Paket übernommen; board_bringup.c legt
+  je nach Panel den passenden DSI-Bus, die DPI-Zeitbasis und den Herstellertreiber an.
+- pins_config.h liefert Auflösung, LCD-Reset-Pin (4,3": GPIO5, 7,0": GPIO27) und Ausrichtung
+  panelabhängig. Das 7-Zoll-Panel ist nativ Querformat, deshalb entfällt dort die 270-Grad-
+  Rotation samt PPA-Beschleunigung.
+- Der GT911 des 7-Zöllers meldet Rohkoordinaten im Raster 800x480 statt 1024x600. Die
+  Umrechnung hängt am process_coordinates-Hook von esp_lcd_touch, damit die Herstellerdatei
+  esp_lcd_touch_gt911.c unverändert bleibt. Ohne sie wäre nur der linke obere Bildteil
+  bedienbar.
+- Die Oberfläche rechnet nicht mehr mit fest verdrahteten 480 Pixeln Höhe, sondern mit
+  DISP_VER_RES. Layout und Schriften bleiben sonst unverändert: Das Dashboard arbeitet fast
+  durchgehend mit Prozentmaßen, und die feineren Pixelabstände des 7-Zöllers (170 statt 213 dpi)
+  lassen dieselben Schriftgrößen physisch größer erscheinen.
+- Die UART-Verkabelung ist bei beiden Panels gleich (P4 GPIO33 = TX, GPIO31 = RX). Beim
+  7-Zöller liegen diese Pins allerdings auf der FPC-Buchse FPC4 (1,0 mm, 16-polig) statt auf
+  einer Stiftleiste - dort wird ein Adapterkabel gebraucht.
+
+Version 1.4.2:
+- Bug-Fix: Beim Aufwecken über Antippen erschien die Auswahl „Espresso oder Cold Extraction"
+  manchmal nicht. Der Dialog entschied nach einer anderen Bedingung, ob er die Auswahl ANZEIGT
+  (verlangte zusätzlich cxArmable), als er beim Absenden benutzte, um die Rückfrage der S3 zu
+  UNTERDRÜCKEN. In der Lücke dazwischen zeigte er nur „Aufwecken", sendete aber „wakeEspresso" -
+  und damit war die Frage auch auf der S3 erledigt. Beide Stellen benutzen jetzt dieselbe Funktion
+  wake_choice_offered().
+- Hat der Dialog die Auswahl nicht angeboten, sendet er wieder „deactivateStandby". Dann öffnet die
+  S3 ihr eigenes Auswahlfenster, und die Frage kommt trotzdem - derselbe Weg wie beim Aufwecken über
+  den Schalter. Die Auswahl kann damit nicht mehr ersatzlos entfallen.
+
+Version 1.4.1:
+- Passend zu S3 5.6.2: Die Auswahl beim Aufwecken erscheint auch dann, wenn der Cold-Extraction-Modus
+  bereits aktiv ist - sie geht in beide Richtungen. „Espresso" schaltet den Modus dann ab.
+- Der Cold-Extraction-Knopf zeigt den Ist-Zustand: Bei aktivem Modus ist er hervorgehoben und heißt
+  „Cold Extraction (aktiv lassen)", sonst „Cold Extraction (Wasser bleibt kalt)".
+
+Version 1.4.0:
+- Die Auswahl „Espresso oder Cold Extraction" erscheint jetzt auch beim Aufwecken über den Schalter
+  (braucht S3-Firmware ab 5.6.0). Meldet die S3 ein offenes Auswahlfenster (cxWakeChoice), blendet das
+  Display den Dialog von sich aus ein - ohne Antippen - und zeigt die verbleibende Bedenkzeit als
+  Countdown. „Abbrechen" entfällt in diesem Fall, weil es nichts abzubrechen gibt: Läuft die Zeit ab,
+  heizt die Maschine normal auf.
+- Der Espresso-Knopf sendet „wakeEspresso" statt „deactivateStandby", sobald die Auswahl relevant ist.
+  Damit wird die Entscheidung auf der S3 vermerkt und nicht direkt danach erneut gefragt.
+- Der Cold-Extraction-Knopf beendet den Standby nur noch, wenn er überhaupt aktiv ist - im Auswahlfenster
+  nach dem Aufwecken schaltet er nur den Modus.
+
 Version 1.3.0:
 - Der Aufweck-Dialog wird zur Auswahl: „Womit aufwecken?" mit den Knöpfen „Espresso" (heizt normal auf)
   und „Cold Extraction (Wasser bleibt kalt)". Braucht S3-Firmware ab 5.5.0.
