-- [REST](https://github.com/dzurikmiroslav/esp32-evse/wiki/Rest) API
- - MQTT API
- - [Modbus](https://github.com/dzurikmiroslav/esp32-evse/wiki/Modbus) (RS485, TCP)
- - [Scripting](https://github.com/dzurikmiroslav/esp32-evse/wiki/Script)

-### Device definition method
+## Features
 
-_One firmware to rule them all._ Not really :-) one per device platform (ESP32, ESP32-S2...).
+### Core EVSE
 
-There is no need to compile the firmware for your EVSE design.
+- EVSE manager (`evse_manager`) coordinating:
-Source code ist not hardcoded to GPIOs or other hardware design features.
+  - Hardware layer (`evse_hardware`)
-All code is written in ESP-IDF without additional mapping layer like Arduino.
+  - State machine (`evse_state`)
+  - Error handling (`evse_error`)
+  - Energy metering (`evse_meter` / `meter_manager`)
+  - Session tracking (`evse_session`)
+- Runs a periodic tick (`evse_manager_tick()`) in its own FreeRTOS task.
+- Supports multiple auth modes (OPEN / RFID / OCPP), with scheduling and load-balancer aware logic.
 
-All configuration is written outside firmware in configuration file named _board.cfg_ on dedicated partition.
+### Networking & REST
-For example, on following scheme is minimal EVSE circuit with ESP32 devkit.
 
-![Minimal circuit](https://github.com/dzurikmiroslav/esp32-evse/wiki/images/minimal-circuit.png)
+- Wi-Fi:
+  - Station mode for normal operation.
+  - Access point mode for local configuration, enabled by a physical button.
+- REST server (`rest_main`) serving from `/data` SPIFFS mount:
+  - For configuration, status, logs, etc. (exact endpoints depend on your REST implementation).
 
-For this circuit there is _board.cfg_, for more information's see [Wiki](https://github.com/dzurikmiroslav/esp32-evse/wiki/Board-config).
+### Button & User Input
 
+- One physical button (configured via `board_config`):
+  - **Short press** → Starts Wi-Fi AP mode for configuration.
+  - **Long press (~30s)** → Erases NVS and reboots (factory-like reset).
+- Robust handling:
+  - ISR with software debounce and spinlock.
+  - Dedicated `user_input_task` that receives button press/release notifications via `xTaskNotify`.
 
-```bash

-PILOT_DOWN_THRESHOLD_3=1491
-PILOT_DOWN_THRESHOLD_N12=265
-#AC relay
-AC_RELAY_GPIO=32
-```
 
-### Web interface
+- SPIFFS used for:
+  - `/cfg` partition: persistent configuration.
+  - `/data` partition: web assets, runtime data, logs, etc.
+- Two separate mounts:
+  - `cfg_conf` → `/cfg` (label: `cfg`)
+  - `data_conf` → `/data` (label: `data`)
 
-Fully responsive web interface is accessible local network IP address on port 80.
+### LED Subsystem
 
-Dashboard page
+- RGB LED driven by LEDC:
+  - `ledc_driver` abstracts LEDC timer + channels.
+  - `led` module maps EVSE state & sessions to colors/patterns.
+- LED patterns per EVSE state:
+  - **IDLE** → Green solid.
+  - **WAITING** (vehicle plugged, not charging) → Blue slow blink.
+  - **CHARGING** → Blue “breathing” effect.
+  - **FAULT** → Red fast blink.
+- Session effects:
+  - Distinct visual patterns when a session starts/finishes.
+  - Uses a one-shot timer and a dedicated effect state machine.
 
-![Dashboard](https://github.com/dzurikmiroslav/esp32-evse/wiki/images/web-dashboard.png) 
+### Buzzer
 
-Settings page
+- Buzzer with multiple patterns (`buzzer` + `buzzer_events`):
+  - Plugged/unplugged, card read/denied, AP start, charging, fault, etc.
+- Supported modes:
+  - Active buzzer (ON/OFF).
+  - Passive buzzer with LEDC PWM (frequency & duty configurable).
+- Features:
+  - Central queue + dedicated `buzzer_task`.
+  - Quiet hours support (optionally suppress non-critical sounds at night).
+  - Anti-spam mechanism to avoid excessively frequent beeps.
+  - Integrated with:
+    - EVSE events (state changes & faults)
+    - Auth events (RFID card success/denied/added)
+    - Network events (AP/STA up)
 
-![Settings](https://github.com/dzurikmiroslav/esp32-evse/wiki/images/web-settings.png)
+### Load Balancer
 
-Mobile dashboard page
+- `loadbalancer` component:
+  - Monitors GRID meter and EVSE meter via `meter_events`.
+  - Supports one master + up to 255 slaves (connectors array).
+  - Fair distribution of current with:
+    - Headroom calculation based on grid limit and measured current.
+    - Min current guarantees (e.g. 6 A) using a “water-filling” algorithm.
+    - Session-age based priority (oldest sessions first).
+    - Per-connector hysteresis and LB suspension/resume flags.
+  - Publishes limits via `LOADBALANCER_EVENTS`:
+    - `LOADBALANCER_EVENT_MASTER_CURRENT_LIMIT`
+    - `LOADBALANCER_EVENT_SLAVE_CURRENT_LIMIT`
+- Fail-safe behavior:
+  - If GRID meter data times out, clamps connectors to minimum safe current instead of ramping up.
 
-![Dashboard mobile](https://github.com/dzurikmiroslav/esp32-evse/wiki/images/web-dashboard-mobile.png)
+### Scheduler
 
-## Hardware
+- Scheduler component (`scheduler`) emits `SCHED_EVENTS` with `allowed_now` flag:
+  - EVSE manager revokes authorization when the window closes.
+  - In OPEN mode, automatic re-authorization only happens when scheduler allows.
 
-### ESP32DevkitC
+### OCPP
 
-Dev board with basic functionality, single phase energy meter, RS485. One side pcb, for DIY makers easy to make at home conditions ;-)
+- `ocpp` module integration:
+  - Listens to OCPP events (`OCPP_EVENTS`).
+  - Handles:
+    - RemoteStart/Stop
+    - Authorization results
+    - ChangeAvailability (operative/inoperative) → mapped into local `enabled` config.
+  - EVSE manager mediates OCPP decisions with scheduler + load balancer.
 
-[EasyEDA project](https://oshwlab.com/dzurik.miroslav/esp32-devkit-evse)
+### Logger
 
-![ESP32DevkitC](https://github.com/dzurikmiroslav/esp32-evse/wiki/images/esp32devkitc.jpg)
+- `logger` + `output_buffer` components:
+  - Central log sink with ring buffer in RAM.
+  - Thread-safe via FreeRTOS mutex.
+  - Integrated with ESP log system via `esp_log_set_vprintf(logger_vprintf);`
+    - Optionally mirrors to UART (controlled via `CONFIG_ESP_CONSOLE_UART`).
+  - Simple reader API:
+    - Iterate entries using an index.
+    - Handy for exposing logs over REST/Web UI.
 
-### ESP32-S2 DIY ALPHA
+---
 
-ESP32-S2 based EVSE with advanced functionality, three phase energy meter, RS485, UART, 1WIRE, RCM, socket lock.

+// Correções aplicadas:
+// 1) Evitar TX dentro do callback RX (ACK deferido para task -> não bloqueia RX)
+// 2) Dedupe de ACK por slave (evita rajadas se RX vier em chunks / queue acumular)
+// 3) Log quando ACK queue enche (antes era silencioso)
+// 4) Proteção concorrente no s_presence (int64_t não é atómico no ESP32 32-bit)
+// 5) Comentário do poll corrigido + opção de jitter no ACK
+//
+// NOTA: Mantive o teu comportamento (POLL a cada 10s). Se quiseres, muda para 30s.

+// Correções aplicadas:
+// 1) Evitar TX dentro do callback RX: confirmação (heartbeat) é deferida via queue/task.
+// 2) Proteger safe_mode (e flags relacionadas) com mux (evita race entre RX e timer).
+// 3) Opção de política no fallback: por default faz PAUSE (mais seguro). Pode ser alterado por macro.
+// 4) Reduzir ruído de logs em caminho quente (RX frames em DEBUG).
+// 5) Manter semântica: só sai de safe_mode com comando explícito de potência (SET_CURRENT / RESUME).
+// 6) Mantém lógica de pause SET_CURRENT=0 e resume quando >0.
+//
