+# Hardware-Checkliste (EVK)
+
+Konsole: `tools/monitor.sh /dev/cu.<port>` (115200 8N1). Flashen: `tools/flash.sh evk <port>`.
+
+## Licht (Plan 1, Task 11)
+- [ ] Nach dem Boot blendet warmweiß 100 % in 0,5 s ein
+- [ ] `rgb 255 0 0` → nur Rot, `rgb 0 255 0` → nur Grün, `rgb 0 0 255` → nur Blau
+- [ ] `ct 2700` → nur Warmweiß, `ct 6500` → nur Kaltweiß, `ct 4000` → Mischung
+- [ ] `bri 1` sichtbar sehr dunkel, `bri 100` hell; `bri 1 3000` → gleichmäßig wirkender Fade
+- [ ] `off 2000` → blendet mit aktueller Farbe aus; `on 2000` → blendet ein
+- [ ] `rgb 255 0 0` dann `ct 3000 2000` → erst dunkel, dann weiß (Moduswechsel)
+- [ ] `blink 3` → 3× Blinken, danach alter Zustand; `pulse on` / `pulse off`
+- [ ] Kein sichtbares Flackern bei konstanten Werten (5 kHz)
+
+## Persistenz und Boot (Plan 1, Task 12)
+- [ ] `pob last`: Farbe setzen, 4 s warten, Strom aus/an → gleicher Zustand, mit Fade
+- [ ] `pob off`: Strom aus/an → bleibt aus; `on` → letzte Farbe
+- [ ] `pob on` bei ausgeschaltetem Licht: Strom aus/an → an
+- [ ] `fade 2000 2000` bleibt nach Reboot erhalten (`state`)
+- [ ] 5× Strom an/aus mit jeweils < 5 s Laufzeit → 3× Blinken, danach Defaults (`state`)
+- [ ] Normaler Boot nach > 5 s Laufzeit → kein Werksreset
+- [ ] Watchdog: `reboot` funktioniert; nach einem Hänger (nicht provozierbar) wäre Reset nach 20 s
+
+## Später (Lampen)
+- [ ] E27 Color (SM2135EH): RGB und WY getrennt, Ströme plausibel (nicht zu heiß)
+- [ ] E27 CW: Gegenphase CW sichtbar flackerfrei
+- [ ] G95: Pinbelegung WW=PB15/CW=PB13 prüfen
+- [ ] Farbtemperaturbereiche aller Varianten
