-# Home Automation Platform
+# Платформа домашней автоматизации
 
-A microservice-based home automation platform, built as a portfolio project
-demonstrating Go (concurrency, message queues, MQTT), PHP/Laravel (API,
-authorization), and polyglot persistence (PostgreSQL, ClickHouse, Redis).
+Pet-проект на микросервисной архитектуре для портфолио, демонстрирующий Go
+(конкурентность, очереди сообщений, MQTT), PHP/Laravel (API, авторизация)
+и работу с разными БД по назначению (PostgreSQL, ClickHouse, Redis).
 
-**This is not a "growbox project."** A growbox is the first implemented
-**zone** with a first set of **device types** (light, pump, fan, temperature
-sensor). The core system — device management, telemetry, automation rules,
-users, notifications — operates purely on the abstractions *zone*, *device*,
-*device type*, *sensor reading*, *command*, *rule*. Nothing growbox-specific
-is hardcoded in the core: adding a "living room" zone with a "smart plug"
-device type should require zero changes to service code, only new rows in
+**Это не «проект гроубокса».** Гроубокс — первая реализованная **зона**
+с первым набором **типов устройств** (свет, полив, вентиляция, датчик
+температуры). Ядро системы — управление устройствами, телеметрия, правила
+автоматизации, пользователи, уведомления — оперирует исключительно
+абстракциями *зона*, *устройство*, *тип устройства*, *показание датчика*,
+*команда*, *правило*. Ничего специфичного для гроубокса не зашито в ядре:
+добавление зоны «гостиная» с типом устройства «умная розетка» не должно
+требовать изменений в коде сервисов — только новые строки в
 `device_types` / `zones` / `devices`.

-## Build stages
+## Этапы разработки
 
-1. **Go services** — ingest, rule-engine, device-control, ESP32 emulator.
-2. **Laravel** — auth (Sanctum, owner/viewer), CRUD for zones/devices/rules,
-   Blade dashboard, manual device control. MVP is considered done here.
-3. *(optional, high value)* **Observability** — Prometheus metrics from the
-   Go services, a Grafana dashboard or two.
-4. **Extensions** (no rush) — Telegram notifications, Vue.js/Inertia
-   frontend, Flutter app, real ESP32 hardware.
+1. **Go-сервисы** — ingest, rule-engine, device-control, эмулятор ESP32.
+2. **Laravel** — авторизация (Sanctum, owner/viewer), CRUD для зон/устройств/
+   правил, Blade-дашборд, ручное управление устройствами. MVP считается
+   готовым на этом этапе.
+3. *(опционально, но сильно повышает ценность)* **Observability** — метрики
+   Prometheus с Go-сервисов, один-два дашборда в Grafana.
+4. **Расширения** (не спеша) — Telegram-уведомления, фронтенд на
+   Vue.js/Inertia, приложение на Flutter, подключение реального ESP32.

-as they're implemented):
+Пока только инфраструктура (сервисы добавляются в `docker-compose.yml` по
+мере реализации):
 
 ```bash
 cp .env.example .env
 docker compose up -d
 ```
 
-This brings up Mosquitto (`1883`), PostgreSQL (`5432`), ClickHouse (`8123`/`9000`),

-- Expose a gRPC API (see `proto/device_control.proto`) for issuing commands
-  to devices — called by Laravel (manual control) and rule-engine-service
-  (rule-triggered actions).
-- Publish the command to the device's MQTT topic (`devices/{device_id}/commands`)
-  and listen for acknowledgements (`devices/{device_id}/ack`).
-- Maintain the Device Shadow pattern in Redis: `desired_state` (what the user
-  wants) vs `reported_state` (what the device confirmed), plus `status` and
-  `last_seen`.
-- Owns the health-check loop (or delegates to health-check-service): a ticker

-  timeout, and emits an event for notification-service.
+Зона ответственности:
+- Предоставляет gRPC API (см. `proto/device_control.proto`) для отправки

+- Публикует команду в MQTT-топик устройства (`devices/{device_id}/commands`)
+  и слушает подтверждения (`devices/{device_id}/ack`).
+- Поддерживает паттерн Device Shadow в Redis: `desired_state` (чего хочет
+  пользователь) против `reported_state` (что подтвердило устройство), плюс
+  `status` и `last_seen`.
+- Владеет циклом health-check (либо делегирует его health-check-service):

-Not this service's job: interpreting what a sensor reading *means* (thresholds,
-actions) — that belongs to rule-engine-service. This service only ingests and
-stores.
-
-Note on `zone_id`: the telemetry payload carries `zone_id` directly (the
-publishing device/emulator is configured with its own zone), rather than
-ingest-service looking it up from PostgreSQL. This keeps ingest-service's
-dependencies limited to MQTT/ClickHouse/RabbitMQ, matching the architecture
-diagram in the root README. A real fleet where devices don't know their own
-zone would need a device-registry lookup (cached, like rule-engine caches
-rules) — that's a natural follow-up, not implemented yet.
-
-## Running
-
-```bash
-cd services/ingest-service
-go test ./...
-go build ./cmd/ingest-service
-```
-
-Configuration is env-var driven (see the ingest-service section of the
-repo-root `.env.example`). Via `docker compose up ingest-service` it talks to
-the `mosquitto`/`clickhouse`/`rabbitmq` containers directly; connect from a
-local `go run` by exporting `MQTT_HOST=localhost`, `CLICKHOUSE_HOST=localhost`, etc.
+Не входит в зону ответственности: интерпретация того, что *означает*

 # rule-engine-service (Go)
 
-Status: not implemented yet.
+Статус: пока не реализован.
 
-Responsibility:
-- Consume "new reading" events from RabbitMQ (async — delivery reliability
-  matters more than latency here).
-- Load active `automation_rules` for the relevant zone/device from PostgreSQL,
-  caching in memory/Redis to avoid a DB round-trip per event.
-- Evaluate rule conditions generically: `sensor_type X operator value` against
-  the reading — no hardcoded sensor/device names, everything comes from the
-  `automation_rules` row.
-- On match: call device-control-service over gRPC (needs a fast pass/fail
-  result) and publish an event to notification-service over RabbitMQ (not
-  latency-critical).
+Зона ответственности:
+- Потребляет события «новое показание» из RabbitMQ (асинхронно — здесь
+  надёжность доставки важнее задержки).
+- Загружает активные `automation_rules` для нужной зоны/устройства из
+  PostgreSQL, кэшируя в памяти/Redis, чтобы не ходить в БД на каждое событие.
+- Оценивает условия правил обобщённо: `sensor_type X operator value` против
+  показания — никаких зашитых названий датчиков/устройств, всё берётся из
+  строки `automation_rules`.
+- При срабатывании: вызывает device-control-service по gRPC (нужен быстрый
+  результат успех/неудача) и публикует событие в notification-service через
+  RabbitMQ (не критично к задержке).
 
-Not this service's job: talking to MQTT or Redis directly — device state
-changes always go through device-control-service's gRPC API.
+Не входит в зону ответственности: прямое взаимодействие с MQTT или Redis —
+изменения состояния устройства всегда идут через gRPC API device-control-service.
