This repository contains two components:

## `custom_components/olimex_esp32_c6`
Home Assistant custom integration for the **Olimex ESP32-C6-EVB** board.

- 4 relay switches (controlled via HTTP POST to the board)
- 4 digital inputs (state pushed from board to HA via webhook)
- No polling — fully event-driven for inputs, command-driven for relays

### Installation
Copy `custom_components/olimex_esp32_c6` into your Home Assistant `config/custom_components/` directory and restart HA.

## `esp32_arduino`
Arduino sketch for the ESP32-C6-EVB board.

- Hosts a REST API on port 80
- Registers a callback URL with HA on startup
- POSTs input state changes to HA webhook in real time
