# Olimex ESP32-C6-EVB — Home Assistant Integration
|
||||
|
||||
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
|
||||
|
||||
### Arduino IDE Settings
|

/**
|
||||
* Olimex ESP32-C6-EVB — Board Functional Test
|
||||
* =================================================
|
||||
* Flash this sketch BEFORE deploying the main firmware.
|
||||
* It tests every hardware subsystem and reports PASS/FAIL
|
||||
* on the Serial Monitor AND on a simple web page.
|
||||
*
|
||||
* Board settings (Arduino IDE):
|
||||
* Board : ESP32C6 Dev Module
|
||||
* USB CDC On Boot : Enabled ← REQUIRED
|
||||
* Flash Size : 4MB
|
||||
* Upload Speed : 921600
|
||||
*
|
||||
* How to read results:
|
||||
* 1. Open Serial Monitor at 115200 baud after upload.
|
||||
* 2. Press RESET on the board — full report prints once.
|
||||
* 3. Connect a phone/PC to the same WiFi and open:
|
||||
* http://192.168.0.181/test (or whatever IP prints)
|
||||
*
|
||||
* Relay self-test: the test pulses each relay 200 ms ON then OFF.
|
||||
* You will see/hear the relays click twice each.
|
||||
*
|
||||
* NFC self-test: tries all baud rates (115200 / 9600 / 57600)
|
||||
* on both pin orientations. Module must be wired on UEXT1.

Olimex ESP32-C6-EVB — Remote Board Verification Script
|
||||
=========================================================
|
||||
Queries the board's REST API and verifies every subsystem.
|
||||
|
||||
Usage:
|
||||
python3 board_verify.py # uses default IP 192.168.0.181
|
||||
python3 board_verify.py 192.168.0.200 # custom IP
|
||||
python3 board_verify.py --json # machine-readable output
|
||||
|
||||
Requirements: pip install requests (already in location_managemet requirements)
|
||||
|
||||
What it tests:
|
||||
1. Board reachability (GET /api/status)
|
||||
2. All 4 relays (POST /relay/on, GET /relay/status, POST /relay/off)
|
||||
3. All 4 digital inputs (GET /input/status)
|
||||
4. LED (POST /led/on + /led/off)
|
||||
5. NFC reader (GET /nfc/status)
|
||||
6. NFC config API (GET /nfc/config)
|
||||
|
||||
NOTE: Relay tests cycle each relay ON→verify→OFF→verify.
|
||||
You should hear/see the relay click during the test.

# Olimex ESP32-C6-EVB Home Assistant Integration Setup Guide
|
||||
|
||||
## Overview
|
||||
|
||||
This Home Assistant integration automatically manages the Olimex ESP32-C6-EVB board configuration through the UI.
|
||||
|
||||
## Features
|
||||
|
||||
- **Binary Sensors** - Monitor 4 digital inputs (DIN1-DIN4)
|
||||
- **Template Switches** - Control 4 relays (REL1-REL4)
|
||||
- **Auto-discovery** - Configurable via config flow UI (no YAML required)
|
||||
- **Connection validation** - Verifies board is online before saving config
|
||||
|
||||
## Installation
|
||||
|
||||
### 1. Deploy Arduino Firmware
|
||||
|
||||
First, ensure your board is running the updated Arduino firmware with all 4 relays and inputs configured:
|
||||
|
||||
- Deploy: `/srv/homeassist/esp32_arduino/esp32_arduino.ino`
|
||||
- Board: Olimex ESP32-C6-EVB
|
||||
- Firmware includes:
|
||||
- Static IP: `192.168.0.181`
|
||||
- 4 Relays (GPIO 10, 11, 22, 23)
|
||||
- 4 Inputs (GPIO 1, 2, 3, 15) with pull-ups
|
||||
|
||||
### 2. Setup Integration via Home Assistant UI
|
||||
|
||||
1. Go to **Settings** → **Devices & Services**
|
||||
2. Click **Create Integration** (+ button)
|
||||
3. Search for **"Olimex"**
|
||||
4. Click **Olimex ESP32-C6-EVB**
|
||||
5. Enter configuration:
|
||||
- **Device IP Address**: `192.168.0.181` (default)
|
||||
- **Port**: `80` (default)
|
||||
- **Scan Interval**: `5` seconds (default)
|
||||
6. Click **Submit**
|
||||
|
||||
The integration will:
|
||||
- ✅ Verify connection to the board
|
||||
- ✅ Create 4 binary sensors for inputs
|
||||
- ✅ Set up the data coordinator for relay polling
|
||||
|
||||
### 3. Create Template Switches (Manual for now)
|
||||
|
||||
For now, you still need to add this to your `configuration.yaml`:
|
||||
|
||||
```yaml
|
||||
template:
|
||||
- switch:
|
||||
- name: "Relay 1"
|
||||
unique_id: "olimex_relay_1"
|
||||
state: "{{ state_attr('sensor.relay_1_status', 'state') | default('off') }}"
|
||||

|
||||
service: rest_command.relay_1_on
|
||||
turn_off:

|
||||
turn_off:

|
||||
|
||||
- name: "Relay 3"
|
||||
unique_id: "olimex_relay_3"
|
||||
state: "{{ state_attr('sensor.relay_3_status', 'state') | default('off') }}"
|
||||
turn_on:
|
||||
service: rest_command.relay_3_on
|
||||
turn_off:
|

|
||||
- `sensor.relay_4_status` - Relay 4 state polling
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Integration won't add
|
||||
- Check board IP is correct (default: `192.168.0.181`)
|
||||
- Verify board is online and connected to WiFi
|
||||
- Check Home Assistant logs: `Settings > System > Logs`
|
||||
|
||||
### Inputs not showing
|
||||
- Verify Arduino firmware is deployed
|
||||
- Check GPIO pin configuration matches board
|
||||
- Inputs show as binary_sensor entities after integration setup
|
||||
|
||||
### Relays not working
|
||||
- Ensure relay REST sensors are created in configuration.yaml
|
||||
- Verify REST commands point to correct IP/port
|
||||
- Check board serial output for API activity
|
||||
|
||||
### Slow response time
|
||||
- Increase scan interval (default is 5 seconds)
|
||||
- Can be changed in integration options
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
- [ ] Auto-create relay switches without YAML
|
||||
- [ ] Add sensor polling via coordinator
|
||||
- [ ] Support multiple boards
|
||||
- [ ] Device discovery (mDNS when available)
|
||||
- [ ] Web UI for board settings

---
|
||||
|
||||
## Step 1: Install Arduino IDE
|
||||
|
||||
1. Download from: https://www.arduino.cc/en/software
|
||||
2. Install and launch Arduino IDE 2.0 or later
|
||||
|
||||
---
|
||||
|
||||
## Step 2: Add ESP32 Board Support
|
||||
|
||||
### Windows/Mac/Linux (same process):
|
||||
|
||||
1. **Open Preferences**
|
||||
- File → Preferences (or Arduino IDE → Settings on Mac)
|
||||
|
||||
2. **Add Board URL**
|
||||
- Find "Additional Boards Manager URLs" field
|
||||
- Add this URL:
|
||||
```
|
||||
https://espressif.github.io/arduino-esp32/package_esp32_index.json
|
||||
```
|
||||
- Click OK
|
||||
|
||||
3. **Install ESP32 Board Package**
|
||||
- Tools → Board → Boards Manager
|
||||
- Search: "esp32"
|
||||
- Install "esp32 by Espressif Systems" (version 3.0.0+)
|
||||
- Wait for installation to complete
|
||||
|
||||
---
|
||||
|
||||
## Step 3: Configure Board Settings
|
||||
|
||||
After installation, configure these exact settings in Arduino IDE:
|
||||
|
||||
**Tools Menu Settings:**
|
||||
|
||||
| Setting | Value |
|
||||
|---------|-------|
|
||||
| Board | ESP32C6 Dev Module |
|
||||
| Upload Speed | 921600 |
|
||||
| USB CDC On Boot | **Enabled** ⚠️ CRITICAL |
|
||||
| Flash Size | 4MB |
|
||||
| Flash Mode | DIO |
|
||||
| Flash Frequency | 80MHz |
|
||||
| Partition Scheme | Default 4MB |
|
||||
|
||||
---
|
||||
|
||||
## Step 4: Update WiFi Credentials
|
||||
|
||||
**Before uploading**, edit the WiFi credentials in `esp32_arduino.ino`:
|
||||
|
||||
```cpp
|
||||
// Line 16-17 - CHANGE THESE:
|
||||
const char* ssid = "Your_WiFi_SSID_Here";
|
||||
const char* password = "Your_WiFi_Password_Here";
|
||||
```
|
||||
|
||||
Replace with your actual WiFi network name and password.
|
||||
|
||||
---
|
||||
|
||||
## Step 5: Connect Board & Find USB Port
|
||||
|
||||
### Linux/Mac:
|
||||
```bash
|
||||
# Check available ports
|
||||
ls -la /dev/ttyACM* /dev/ttyUSB*
|
||||
|
||||
# Should see something like: /dev/ttyACM0
|
||||
```
|
||||
|
||||
### Windows:
|
||||
- Device Manager → Ports (COM & LPT)
|
||||
- Look for "USB-UART Bridge" or similar
|
||||
|
||||
### Select Port in Arduino IDE:
|
||||
- Tools → Port → [Select your port]
|
||||
- Usually `/dev/ttyACM0` on Linux (not `/dev/ttyUSB0`)
|
||||
|
||||
---
|
||||
|
||||
## Step 6: Compile & Upload
|
||||
|
||||
1. **Verify Sketch** (check for errors before upload)
|
||||
- Sketch → Verify/Compile
|
||||
- OR press: Ctrl+R (Windows/Linux) or Cmd+R (Mac)
|
||||
|
||||
2. **Upload to Board**
|
||||
- Sketch → Upload
|
||||
- OR press: Ctrl+U (Windows/Linux) or Cmd+U (Mac)
|
||||
|
||||
3. **Watch Serial Monitor**
|
||||
- Tools → Serial Monitor (or Ctrl+Shift+M)
|
||||
- **Set baud rate to: 115200**
|
||||
- You should see the startup messages
|
||||
|
||||
4. **If No Output:**
|
||||
- Press the **RESET button** on the ESP32-C6 board
|
||||
- Check that "USB CDC On Boot" is set to **Enabled**
|
||||
- Verify Serial Monitor baud rate is 115200
|
||||
|
||||

|
||||
|
||||
## Step 7: Verify Deployment Success
|
||||
|
||||
