# NFC (PN532) Debugging Guide
|
||||||
|
|
||||||
|
## Current Status
|
||||||
|
- **Hardware**: GPIO26(TX) → PN532 RXD, GPIO25(RX) ← PN532 TXD (UEXT pins 3-4)
|
||||||
|
- **DIP Switches**: Both OFF (HSU mode) ✓
|
||||||
|
- **Power**: UEXT pin 1 = 3.3V (verified), Pin 2 = GND (verified)
|
||||||
|
- **Wiring**: Confirmed correct
|
||||||
|
- **Problem**: PN532 module not responding to auto-baud probe
|
||||||
|
|
||||||
|
## Why NFC Probe Fails
|
||||||
|
The firmware attempts to communicate with PN532 at various baud rates:
|
||||||
|
- 115200, 9600, 57600, 38400 baud
|
||||||
|
- Tries both GPIO26/GPIO25 and GPIO25/GPIO26 (swapped)
|
||||||
|
- At each combination: sends `getFirmwareVersion()` command
|
||||||
|
- **Issue**: No response from PN532 → returns 0x00
|
||||||
|
|
||||||
|
## Prerequisites for Debugging
|
||||||
|
### 1. Enable Serial Output
|
||||||
|
**Arduino IDE Settings (REQUIRED):**
|
||||||
|
```
|
||||||
|
Tools → USB CDC On Boot: ENABLED
|
||||||
|
Tools → Port: /dev/ttyACM0
|
||||||
|
```
|
||||||
|
|
||||||
|
**Rebuild and flash the firmware:**
|
||||||
|
```bash
|
||||||
|
cd ~/arduino/olimex_ESP32-C5-EVB/esp32_arduino
|
||||||
|
arduino --verify --board esp32:esp32:esp32c5 esp32_arduino.ino
|
||||||
|
esptool.py --chip esp32c5 --port /dev/ttyACM0 --baud 921600 erase-flash
|
||||||
|
esptool.py --chip esp32c5 --port /dev/ttyACM0 --baud 921600 write-flash 0x0 build_output/esp32_arduino.ino.merged.bin
|
||||||
|
```
|
||||||
|
|
||||||
|
**Open Serial Monitor:**
|
||||||
|
- Arduino IDE → Tools → Serial Monitor
|
||||||
|
- Baud rate: **115200**
|
||||||
|
- Wait for boot messages
|
||||||
|
|
||||||
|
## Diagnostic Steps
|
||||||
|
|
||||||
|
### Step 1: Verify Serial Output
|
||||||
|
Expected output during boot:
|
||||||
|
```
|
||||||
|
=================================
|
||||||
|
ESP32-C5 Home Assistant Device
|
||||||
|
Arduino Framework
|
||||||
|
=================================
|
||||||
|
...
|
||||||
|
--- NFC (PN532 HSU) Initialization with Debug ---
|
||||||
|
Hardware: GPIO26(TX)→PN532-RX, GPIO25(RX)←PN532-TX, DIP:HSU mode
|
||||||
|
[1/8] Baud=115200, RX=GPIO25, TX=GPIO26 ... ✗
|
||||||
|
[2/8] Baud=9600, RX=GPIO25, TX=GPIO26 ... ✗
|
||||||
|
...
|
||||||
|
```
|
||||||
|
|
||||||
|
**If you see:**
|
||||||
|
- ✓ All "✗" symbols → PN532 not responding at any baud rate
|
||||||
|
- Nothing after "Initialization" → Serial output not working (re-check USB CDC setting)
|
||||||
|
|
||||||
|
### Step 2: Physical Verification Checklist
|
||||||
|
```
|
||||||
|
□ PN532 powered: Measure 3.3V on VCC pin (should be 3.0-3.3V)
|
||||||
|
□ PN532 GND: Verify continuity to board GND with multimeter
|
||||||
|
□ UEXT Pin 1: Should be 3.3V (measure with multimeter)
|
||||||
|
□ UEXT Pin 2: Should be GND (continuity check)
|
||||||
|
□ UEXT Pin 3 (GPIO26): No continuity to Pin 4 (should be separate signals)
|
||||||
|
□ UEXT Pin 4 (GPIO25): No continuity to Pin 3 (should be separate signals)
|
||||||
|
□ PN532 Module: Try re-seating in connector or using different PN532 board
|
||||||
|
```
|
||||||
|
|
||||||
|
### Step 3: Signal Analysis (Advanced)
|
||||||
|
If serial output shows all "✗" but hardware checks pass:
|
||||||
|
|
||||||
|
**Option A: Oscilloscope Check**
|
||||||
|
```
|
||||||
|
Connect oscilloscope probe to GPIO26 (TX line)
|
||||||
|
- Should see UART signal transitions during probe
|
||||||
|
- If flat line: ESP32 not transmitting
|
||||||
|
- If signal present: PN532 not responding
|
||||||
|
```
|
||||||
|
|
||||||
|
**Option B: Loopback Test**
|
||||||
|
```
|
||||||
|
Connect GPIO26 (TX) directly to GPIO25 (RX) with a jumper wire
|
||||||
|
Rebuild with loopback test code (at end of this file)
|
||||||
|
If loopback works: GPIO pins OK, PN532 module is issue
|
||||||
|
If loopback fails: GPIO configuration issue
|
||||||
|
```
|
||||||
|
|
||||||
|
## Possible Issues & Solutions
|
||||||
|
|
||||||
|
### Issue 1: PN532 Module Defective
|
||||||
|
**Symptoms:** All baud rates fail, hardware verified correct
|
||||||
|
**Solution:**
|
||||||
|
- Try different PN532 board if available
|
||||||
|
- Test with I2C mode (different DIP setting) if supported
|
||||||
|
- Replace PN532 module
|
||||||
|
|
||||||
|
### Issue 2: UEXT Connector Loose
|
||||||
|
**Symptoms:** Intermittent detection or complete failure
|
||||||
|
**Solution:**
|
||||||
|
- Fully remove and re-seat PN532 in UEXT connector
|
||||||
|
- Ensure connector is fully inserted until it clicks
|
||||||
|
- Check for bent pins on UEXT connector
|
||||||
|
|
||||||
|
### Issue 3: Incorrect Pin Mapping
|
||||||
|
**Symptoms:** Detection works with swapped pins
|
||||||
|
**Solution:**
|
||||||
|
- Edit `esp32_arduino.ino`:
|
||||||
|
- Find: `#define NFC_TX_PIN 26` and `#define NFC_RX_PIN 25`
|
||||||
|
- If swapped RX/TX works: reverse these definitions
|
||||||
|
- Rebuild and test
|
||||||
|
|
||||||
|
### Issue 4: Baud Rate Mismatch
|
||||||
|
**Symptoms:** Serial output shows some attempts as "✓ FOUND!" but then fails to init
|
||||||
|
**Solution:**
|
||||||
|
- Firmware will re-init with confirmed baud rate
|
||||||
|
- If fails at SAMConfig() step: PN532 module may be in wrong mode
|
||||||
|
|
||||||
|
## Loopback Test Code
|
||||||
|
(If GPIO pins might be misconfigured):
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
// Add to setup() after WiFi init, BEFORE NFC init:
|
||||||
|
void setup() {
|
||||||
|
// ... existing code ...
|
||||||
|
|
||||||
|
// LOOPBACK TEST
|
||||||
|
Serial.println("--- GPIO Loopback Test ---");
|
||||||
|
Serial.println("Jumper GPIO26 to GPIO25 to test UART");
|
||||||
|
|
||||||
|
HardwareSerial testSerial(1); // UART1
|
||||||
|
testSerial.begin(115200, SERIAL_8N1, 25, 26); // RX=GPIO25, TX=GPIO26
|
||||||
|
|
||||||
|
delay(100);
|
||||||
|
testSerial.print("TEST_LOOPBACK");
|
||||||
|
delay(100);
|
||||||
|
|
||||||
|
String received = "";
|
||||||
|
while (testSerial.available()) {
|
||||||
|
received += (char)testSerial.read();
|
||||||
|
}
|
||||||
|
|
||||||
|
if (received.indexOf("TEST") >= 0) {
|
||||||
|
Serial.println("✓ GPIO26/GPIO25 loopback OK");
|
||||||
|
} else {
|
||||||
|
Serial.println("✗ GPIO loopback FAILED - pin configuration issue");
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Next Steps
|
||||||
|
1. **Enable Serial Output**: Change USB CDC On Boot to ENABLED
|
||||||
|
2. **Rebuild & Flash**: Use updated Arduino IDE settings
|
||||||
|
3. **Monitor Serial**: Watch boot output during NFC probe
|
||||||
|
4. **Share Output**: Post the serial output here for analysis
|
||||||
|
|
||||||
|
**Expected Timeline:**
|
||||||
|
- Checking serial output: ~5 minutes
|
||||||
|
- Physical verification: ~10 minutes
|
||||||
|
- Analyzing results: ~5 minutes
|
||||||
|
- **Total**: ~20 minutes to identify root cause

|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Board not reachable
|
||||||
|
1. Check WiFi SSID and password in code
|
||||||
|
2. Verify board IP with serial console output
|
||||||
|
3. Check firewall allows port 80
|
||||||
|
|
||||||
|
### Inputs not triggering
|
||||||
|
1. Verify wiring to opto-isolated inputs (GPIO4, GPIO5)
|
||||||
|
2. Use `/debug` endpoint to check input state
|
||||||
|
3. Ensure Home Assistant callback URL is registered
|
||||||
|
|
||||||
|
### NFC not detecting cards
|
||||||
|
1. Check PN532 wiring (TX=GPIO26, RX=GPIO25)
|
||||||
|
2. Set PN532 DIP switches to HSU mode (both = 0)
|
||||||
|
3. Check serial output for PN532 detection message
|
||||||
|
4. Try different baud rates (115200, 9600, 57600, 38400)
|
||||||

## Security Notes
|
||||||
|
|
||||||
|
- Default credentials: admin / admin
|
||||||
|
- Change WEB_PASSWORD in `secrets.h` before deployment
|
||||||
|
- Enable API_SECRET for HMAC-SHA256 request signing (optional)
|
||||||
|
- Only expose board on trusted local networks
|

# ESP32-C5 Arduino Deployment Guide
|
||||||
|
|
||||||
|
Complete guide to compile and deploy the firmware to your Olimex ESP32-C5-EVB board.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## ✓ Pre-Deployment Checklist
|
||||||
|
|
||||||
|
- [ ] Arduino IDE installed (version 2.0+)
|
||||||
|
- [ ] ESP32 board package installed (version 3.0.0+)
|
||||||
|
- [ ] Olimex ESP32-C5-EVB board connected via USB
|
||||||
|
- [ ] USB drivers installed for your OS
|
||||||
|
- [ ] WiFi credentials available
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Step 1: Install Arduino IDE
|
||||||
|
|
||||||
|
1. Download from: https://www.arduino.cc/en/software
|
||||||
|
2. Install and launch **Arduino IDE 2.0 or later**
|
||||||
|
|
||||||
|
**⚠️ Arduino IDE 1.x (including the system package `arduino` on Linux) will NOT work with ESP32 core 3.x.**
|
||||||
|
Core 3.x uses nested variable references in its build system that only Arduino IDE 2.x resolves correctly.
|
||||||
|
Installing `arduino` via `apt` gives you IDE 1.8.19 — download the AppImage/zip directly from arduino.cc instead.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 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 | **ESP32C5 Dev Module** |
|
||||||
|
| USB CDC On Boot | **Enabled** ⚠️ **REQUIRED for Serial Monitor** |
|
||||||
|
| Flash Size | **4MB** |
|
||||||
|
| Flash Frequency | **80 MHz** |
|
||||||
|
| Flash Mode | **QIO** (default for C5) |
|
||||||
|
| PSRAM | Disabled |
|
||||||
|
| CPU Frequency | 240 MHz (WiFi) |
|
||||||
|
| Core Debug Level | None |
|
||||||
|
| Partition Scheme | **No OTA (2MB APP/2MB SPIFFS)** |
|
||||||
|
| Port | `/dev/ttyACM0` (Linux) or `/dev/cu.usbserial-*` (Mac) |
|
||||||
|
|
||||||
|
> **Note:** The ESP32-C5 does not have a "USB Mode" menu. Its USB hardware is fixed (Hardware CDC).
|
||||||
|
> The correct partition scheme for 4 MB flash is **No OTA (2MB APP/2MB SPIFFS)** — this gives 2 MB app space vs 1 MB with `noota_3g`.
|
||||||
|
|
||||||
|
**⚠️ IMPORTANT:**
|
||||||
|
- **USB CDC On Boot MUST be ENABLED** for Serial output to work in Arduino IDE Serial Monitor
|
||||||
|
- The device will show 2 serial ports when USB CDC is enabled:
|
||||||
|
- First port: USB CDC (for Serial.print output)
|
||||||
|
- Second port: USB-UART (legacy, can be ignored)
|
||||||
|
|
||||||
|
**⚠️ Important:** USB CDC On Boot must be **Enabled** for serial output to work!
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Step 4: Install Required Libraries
|
||||||
|
|
||||||
|
The sketch uses these libraries. Install them via Sketch → Include Library → Manage Libraries:
|
||||||
|
|
||||||
|
1. **PN532** (by Elechouse)
|
||||||
|
- Search: "PN532"
|
||||||
|
- Install the official PN532 library by Elechouse
|
||||||
|
- Version: 1.32 or later
|
||||||
|
|
||||||
|
2. Other libraries (WiFi, WebServer, Preferences) are built-in to ESP32 core
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Step 5: Configure Secrets
|
||||||
|
|
||||||
|
1. Copy `secrets.h.example` to `secrets.h` in the same directory:
|
||||||
|
```bash
|
||||||
|
cp esp32_arduino/secrets.h.example esp32_arduino/secrets.h
|
||||||
|
```
|
||||||
|
|
||||||
|
2. Edit `secrets.h` with your credentials:
|
||||||
|
```cpp
|
||||||
|
const char* WEB_USER = "admin";
|
||||||
|
const char* WEB_PASSWORD = "admin"; // Change this!
|
||||||
|
const char* API_SECRET = ""; // Optional HMAC secret
|
||||||
|
```
|
||||||
|
|
||||||
|
3. Also update WiFi credentials in `esp32_arduino.ino` (around line 58):
|
||||||
|
```cpp
|
||||||
|
const char* ssid = "YOUR_SSID";
|
||||||
|
const char* password = "YOUR_PASSWORD";
|
||||||
|
```
|
||||||
|
|
||||||
|
**⚠️ Never commit `secrets.h` to Git!**
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Step 6: Flash the Board
|
||||||
|
|
||||||
|
### Connect the Board:
|
||||||
|
1. Plug the Olimex ESP32-C5-EVB into your computer via USB
|
||||||
|
2. Wait for USB drivers to load (Windows: ~30 seconds)
|
||||||
|
|
||||||
|
### In Arduino IDE:
|
||||||
|
1. Open `esp32_arduino.ino`
|
||||||
|
2. Tools → Port → Select your board's port
|
||||||
|
- **Linux:** `/dev/ttyUSB0`, `/dev/ttyUSB1`, or `/dev/ACM0`
|
||||||
|
- **macOS:** `/dev/cu.usbserial-*` or `/dev/cu.SLAB_USBtoUART`
|
||||||
|
- **Windows:** `COM3`, `COM4`, etc.
|
||||||
|
|
||||||
|
3. Sketch → Upload (or press Ctrl+U / Cmd+U)
|
||||||
|
|
||||||
|
4. Wait for compilation and flashing to complete (~30 seconds)
|
||||||
|
|
||||||

||||||
|
---
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Board doesn't show in Port menu:
|
||||||
|
- Install drivers: https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers
|
||||||
|
- Try different USB cable
|
||||||
|
- Check Device Manager (Windows) or System Report (Mac)
|
||||||
|
|
||||||
|
### Serial output garbled:
|
||||||
|
- Check baud rate is **115200** in Serial Monitor
|
||||||
|
- Try different baud rates (9600, 57600)
|
||||||
|
|
||||||
|
### WiFi connection fails:
|
||||||
|
- Verify SSID and password in `esp32_arduino.ino`
|
||||||
|
- Check 2.4 GHz WiFi is enabled (C5 may not support 5 GHz yet)
|
||||||
|
- Power cycle board and router
|
||||||
|
|
||||||
|
### NFC not detected:
|
||||||
|
- Check PN532 is soldered correctly to UEXT connector
|
||||||
|
- Verify TX=GPIO26, RX=GPIO25 wiring
|
||||||
|
- Set PN532 DIP switches to HSU mode (both = 0)
|
||||||
|
- Check serial output for baud detection attempts
|
||||||
|
|
||||||
|
### Can't reach board from Home Assistant:
|
||||||
|
- Verify board IP: check serial monitor output
|
||||||
|
- Ping from HA machine: `ping 192.168.0.240`
|
||||||
|
- Check firewall allows port 80
|
||||||
|
- Ensure HA and board are on same network
|
||||||

|
## Protecting Your Device
|
||||||
|
|
||||||
|
**Before deployment to production:**
|
||||||
|
|
||||||
|
1. Change default credentials in `secrets.h`:
|
||||||
|
```cpp
|
||||||
|
const char* WEB_USER = "secure_user";
|
||||||
|
const char* WEB_PASSWORD = "strong_password_123";
|
||||||
|
```
|
||||||
|
|
||||||
|
2. Set an API secret for request signing:
|
||||||
|
```cpp
|
||||||
|
const char* API_SECRET = "my_random_secret_key_xyz123";
|
||||||
|
```
|
||||||
|
|
||||||
|
3. Only expose board on trusted networks (private LAN)
|
||||||
|
|
||||||
|
4. Consider firewall rules to restrict access
|
||||||
|
|
||||||

# 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
|
||||||
|
|
||||||
|

/**
|
||||||
|
* 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.

## ESP32 Firmware Development
|
||||||
|
|
||||||
|
### Required API Endpoints
|
||||||
|
|
||||||
|
Your ESP32 firmware should implement these HTTP endpoints:
|
||||||
|
|
||||||
|
#### Status Endpoint
|
||||||
|
```
|
||||||
|
GET http://<IP>:<PORT>/api/status
|
||||||
|
Response: {
|
||||||
|
"temperature": 25.5,
|
||||||
|
"wifi_rssi": -45
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Relay Control
|
||||||
|
```
|
||||||
|
POST http://<IP>:<PORT>/api/relay/<relay_id>/on
|

# 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') }}"
|
||||||
|
turn_on:
|
||||||
|
service: rest_command.relay_1_on
|
||||||
|
turn_off:
|
||||||
|
service: rest_command.relay_1_off
|
||||||
|
|
||||||
|
- name: "Relay 2"
|
||||||
|
unique_id: "olimex_relay_2"
|
||||||
|
state: "{{ state_attr('sensor.relay_2_status', 'state') | default('off') }}"
|
||||||
|
turn_on:
|
||||||
|
service: rest_command.relay_2_on
|
||||||
|
turn_off:
|
||||||
|
service: rest_command.relay_2_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:
|
||||||
|
service: rest_command.relay_3_off
|
||||||
|
|
||||||
|
- name: "Relay 4"
|
||||||
|
unique_id: "olimex_relay_4"
|
||||||
|
state: "{{ state_attr('sensor.relay_4_status', 'state') | default('off') }}"
|
||||||
|
turn_on:
|
||||||
|
service: rest_command.relay_4_on
|
||||||
|
turn_off:
|
||||||
|

|
method: POST
|
||||||
|
relay_4_off:
|
||||||
|
url: "http://192.168.0.181/relay/off?relay=4"
|
||||||
|
method: POST
|
||||||
|
```
|
||||||
|
|
||||||
|
Then restart Home Assistant.
|
||||||
|
|
||||||
|
## API Endpoints
|
||||||
|
|
||||||
|
The board provides these REST API endpoints:
|
||||||
|
|
||||||
|
### Relay Control
|
||||||
|
- `POST /relay/on?relay=1-4` - Turn relay on
|
||||||
|
- `POST /relay/off?relay=1-4` - Turn relay off
|
||||||
|
- `GET /relay/status?relay=1-4` - Get relay state (returns `{"state": true/false}`)
|
||||||
|
|
||||||
|
### Input Reading
|
||||||
|
- `GET /input/status?input=1-4` - Read input state (returns `{"state": true/false}`)
|
||||||
|
|
||||||
|
### Device Status
|
||||||
|
- `GET /api/status` - Get overall device status
|
||||||
|
|
||||||
|
## Entities Created
|
||||||
|
|
||||||
|
### Binary Sensors (Inputs)
|
||||||
|
- `binary_sensor.input_1` - Digital Input 1 (GPIO 1)
|
||||||
|
- `binary_sensor.input_2` - Digital Input 2 (GPIO 2)
|
||||||
|
- `binary_sensor.input_3` - Digital Input 3 (GPIO 3)
|
||||||
|
- `binary_sensor.input_4` - Digital Input 4 (GPIO 15)
|
||||||
|
|
||||||
|
### Switches (Relays) - via template
|
||||||
|
- `switch.relay_1` - Relay 1 (GPIO 10)
|
||||||
|
- `switch.relay_2` - Relay 2 (GPIO 11)
|
||||||
|
- `switch.relay_3` - Relay 3 (GPIO 22)
|
||||||
|
- `switch.relay_4` - Relay 4 (GPIO 23)
|
||||||
|
|
||||||
|
### Sensors (Status)
|
||||||
|
- `sensor.relay_1_status` - Relay 1 state polling
|
||||||
|
- `sensor.relay_2_status` - Relay 2 state polling
|
||||||
|
- `sensor.relay_3_status` - Relay 3 state polling
|
||||||
|
- `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

||||||
|
After installation, configure these exact settings in Arduino IDE:
|
||||||
|
|
||||||
|
**Tools Menu Settings:**
|
||||||
|
|
||||||
|
| Setting | Value |
|
||||||
|

|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 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
|
||||||
|
|
||||||

|
||||||
|
✓ WiFi connected!
|
||||||
|
IP address: 192.168.1.xxx
|
||||||
|
RSSI: -45 dBm
|
||||||
|
MAC: AA:BB:CC:DD:EE:FF

```
|
||||||
|
|
||||||
|
### Test the Board
|
||||||
|
|
||||||
|
**From Linux terminal or browser:**
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Get board status
|
||||||
|
curl http://192.168.1.xxx/api/status

|
|
||||||
|
# Expected response:
|
||||||
|
# {"temperature":25.0,"wifi_rssi":-45,"chip":"ESP32-C6","free_heap":123456,"uptime":12,"ip":"192.168.1.xxx","relay1":false,"led":false}
|
||||||
|
|
||||||
|
# Turn relay ON
|
||||||
|
curl -X POST http://192.168.1.xxx/api/relay/relay_1/on
|
||||||
|
|
||||||
|
# Turn relay OFF
|
||||||
|
curl -X POST http://192.168.1.xxx/api/relay/relay_1/off
|
||||||
|
|
||||||
|
# Get relay status
|
||||||
|
curl http://192.168.1.xxx/api/relay/relay_1/status
|
||||||
|
|
||||||
|
# Turn LED ON
|
||||||
|
curl -X POST http://192.168.1.xxx/api/led/led/on
|
||||||
|
|
||||||
|
# Turn LED OFF
|
||||||
|
curl -X POST http://192.168.1.xxx/api/led/led/off
|
||||||
|
```
|
||||||
|
|
||||||
|
**Or open in browser:**
|
||||||
|
- `http://192.168.1.xxx/` - Web control panel
|
||||||
|
- `http://192.168.1.xxx/api/status` - JSON status
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Step 8: Add to Home Assistant
|
||||||
|
|
||||||
|

||||||
|
|
||||||
|
2. **In Home Assistant:**
|
||||||
|
- Settings → Devices & Services → Integrations
|
||||||
|
- Click "+ Create Integration"
|
||||||
|
- Search for "Olimex ESP32-C6-EVB"
|
||||||
|
- Enter IP address and port (80)
|
||||||
|
- Select which relays/LEDs to include
|
||||||
|
|
||||||
|
3. **You should now see:**
|
||||||
|
- Temperature sensor
|
||||||
|
- WiFi signal strength
|
||||||
|
- Relay switch
|
||||||
|
- LED switch
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### No Serial Output
|
||||||
|
- ✓ Verify "USB CDC On Boot" is **Enabled** in board settings
|
||||||
|
- ✓ Press RESET button on the board
|
||||||
|
- ✓ Check Serial Monitor baud rate (115200)
|
||||||
|
- ✓ Try different USB cable
|
||||||
|
- ✓ Try different USB port
|
||||||
|
|
||||||
|
### WiFi Connection Failed
|
||||||
|
- ✓ Verify SSID and password are correct (check for typos)
|
||||||
|
- ✓ Ensure board is within WiFi range
|
||||||
|
- ✓ Check if WiFi network requires WPA3 (ESP32-C6 may have issues with some WPA3 networks)
|
||||||
|
- ✓ Try 2.4GHz network (not 5GHz)
|
||||||
|
|
||||||
|
### Can't Find Board in Arduino IDE
|
||||||
|
- ✓ Check USB cable is connected
|

|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Board Not Found in Arduino IDE
|
||||||
|
- Make sure you installed ESP32 board support (minimum version 3.0.0)
|
||||||
|
- Restart Arduino IDE after installation
|
||||||
|
|
||||||
|
### Upload Fails
|
||||||
|
- Check USB cable connection
|
||||||
|
- Select correct port in Tools → Port
|
||||||
|
- Try pressing BOOT button during upload
|
||||||
|
- Reduce upload speed to 115200
|
||||||
|
|
||||||
|
### WiFi Connection Fails
|
||||||
|
- Verify SSID and password
|
||||||
|
- Check if WiFi is 2.4GHz (ESP32-C6 doesn't support 5GHz)
|
||||||
|
- Check Serial Monitor for connection messages
|
||||||
|
|
||||||
|
### Can't See Serial Output
|
||||||
|
- Set Serial Monitor baud rate to **115200**
|
||||||
|
- Enable "USB CDC On Boot" in board settings
|
||||||
|
- Some boards need GPIO 0 held LOW during boot to enter programming mode
|
||||||
|
|
||||||
|
