DETA Grid Connect Smart Switch (Single 6911HA / Double 6912HA / Triple 6903HA / Quad 6904HA): ESPHome

Стартовый конфиг ESPHome

Собран по распиновке выше. Ключи и пароль Wi-Fi берутся из secrets.yaml в ESPHome. Перед прошивкой сверьте пины со своей ревизией устройства: у одной модели бывают разные платы.

Как прошить

• Большинство устройств прошивают по UART: адаптер USB-TTL на 3,3 В к пинам RX, TX, GND и 3V3, при включении зажать GPIO0 на землю (для ESP8266/ESP32). Сетевое питание при этом отключено.
• Чипы Beken (BK72xx) и Realtek прошивают через ltchiptool или cloudcutter без вскрытия — если прошивка устройства это допускает.
• Подробности и фотографии платы — страница устройства в базе ESPHome.

Свой конфиг с нуля — генератор ESPHome. Какие пины безопасны — распиновка.
