📱 Управление чайником Xiaomi через Node-RED\n*Xiaomi Kettle Control via Node-RED*\n\n## 🔧 Настройка / Setup\n1. **Установите чайник на док-станцию**  \n   *Place the kettle on the docking station*\n\n2. **Укажите MAC-адрес и токен чайника в переменных окружения:**  \n   *Set kettle MAC address and token in environment variables:*\n   - `mac` - MAC-адрес чайника / *Kettle MAC address*\n   - `token` - Токен устройства / *Device token*\n\n## 🎮 Управление / Control\n\n### 🟢 Активация чайника / Kettle Activation\n- **Нажмите кнопку \"Warm\" на чайнике** - активирует режим управления  \n  *Press \"Warm\" button on kettle - activates control mode*\n\n### 🔥 Запуск нагрева / Start Heating\n**Способ 1:** Быстро дважды нажмите \"Warm\" на чайнике (в течение 2 сек)  \n*Method 1: Double-press \"Warm\" button on kettle quickly (within 2 sec)*\n\n**Способ 2:** Нажмите кнопку \"Heat Water\" в Node-RED  \n*Method 2: Press \"Heat Water\" button in Node-RED*\n\n➡️ Чайник нагреет воду до 80°C и будет поддерживать температуру  \n*Kettle will heat water to 80°C and maintain temperature*\n\n### ⏹️ Остановка нагрева / Stop Heating\n- **Нажмите \"Stop Heating\"** - снизит температуру до 40°C, но останется в активном режиме  \n  *Press \"Stop Heating\" - lowers temperature to 40°C but keeps active mode*\n\n### 🔴 Полное отключение / Complete Shutdown\n- **Поднимите чайник или отпустите кнопку \"Warm\"** - переведет в режим остывания  \n  *Lift kettle or release \"Warm\" button - switches to cooling mode*\n\n## 📊 Индикаторы состояния / Status Indicators\n\n| Статус | Описание | *Status* | *Description* |\n|--------|----------|-----------|---------------|\n| 🔵 Синий | Нагрев до целевой температуры | *Blue* | *Heating to target temperature* |\n| 🟢 Зеленый | Поддержание температуры | *Green* | *Maintaining temperature* |\n| 🟡 Желтый | Переключение режима | *Yellow* | *Switching mode* |\n| ⚪ Серый | Режим ожидания/остывания | *Gray* | *Standby/cooling mode* |\n| 🔴 Красный | Отключен/ошибка | *Red* | *Disconnected/error* |\n\n## ⚠️ Важно / Important\n- **Чайник должен быть на док-станции** для работы по Bluetooth  \n  *Kettle must be on docking station for Bluetooth operation*\n- **Кнопка \"Warm\" должна быть активна** для удаленного управления  \n  *\"Warm\" button must be active for remote control*\n- **Автоматическое переподключение** при потере связи каждые 30 секунд  \n  *Automatic reconnection on connection loss every 30 seconds*\n\n## 🔄 Логика работы / Operation Logic\n1. **Нагрев (heat_to_temperature)** - точный контроль температуры, НЕ кипятит  \n   *Heating (heat_to_temperature) - precise temperature control, does NOT boil*\n2. **Остывание (boil_and_cool_down)** - используется только при отключении  \n   *Cooling (boil_and_cool_down) - used only when kettle is off*","x":700,"y":40,"wires":[]},{"id":"e7713296f5f01d59","type":"xmihome-config","name":"ble","debug":true,"connectionType":"bluetooth"}]
