# Code Review: DD3 LoRa Bridge MultiSender
|
||||
**Date:** March 11, 2026
|
||||
**Reviewer:** Security Analysis
|
||||
**Focus:** Buffer overflows, memory issues, security risks, and bugs
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
The codebase is generally well-written with good defensive programming practices. Most critical vulnerabilities are mitigated through bounds checking and safe API usage. However, there are several issues ranging from minor to moderate severity that should be addressed.
|
||||
|
||||
---
|
||||
|
||||
## Critical Issues
|
||||
|
||||
### 1. ⚠️ **No HTTPS/TLS - Credentials transmitted in plaintext**
|
||||
**Severity:** CRITICAL
|
||||
**File:** [web_server.cpp](src/web_server.cpp)
|
||||
**Issue:** The web server runs on plain HTTP (port 80) without any encryption.
|
||||
- WiFi credentials, MQTT credentials, and API authentication are sent in plaintext
|
||||
- All data exchanges (history, configuration, status) are unencrypted
|
||||
- An attacker on the network can easily capture credentials and impersonate users
|
||||
- User login credentials transmitted via HTTP Basic Auth are also vulnerable
|
||||
|
||||
**Impact:** Complete loss of confidentiality for all sensitive data
|
||||
**Recommendation:**
|
||||
- Implement HTTPS/TLS support on the ESP32 web server
|
||||
- Consider at minimum disabling HTTP when HTTPS is available
|
||||
- Alternatively, restrict web access to local network only with firewall rules
|
||||
- Document this limitation prominently
|
||||
|
||||
**Code:** [web_server.cpp L580-620](src/web_server.cpp#L576) - All `server.send()` calls use HTTP
|
||||
|
||||
---
|
||||
|
||||
### 2. ⚠️ **Default weak credentials - "admin/admin"**
|
||||
**Severity:** HIGH
|
||||
**File:** [config.h](include/config.h#L83)
|
||||
**Issue:**
|
||||
```cpp
|
||||
constexpr const char *WEB_AUTH_DEFAULT_USER = "admin";
|
||||
constexpr const char *WEB_AUTH_DEFAULT_PASS = "admin";
|
||||
```
|
||||
|
||||
**Impact:** Default accounts are easily guessable; most users won't change them, especially in AP mode where `WEB_AUTH_REQUIRE_AP = false` (no auth required)
|
||||
**Recommendation:**
|
||||
- Force users to create strong credentials during initial setup
|
||||
- Generate random default credentials (or use MAC address-based credentials)
|
||||
- Never store credentials in plain-text constants
|
||||
- In AP mode, either enable auth or display a security warning
|
||||
|
||||
---
|
||||
|
||||
## High Priority Issues
|
||||
|
||||
### 3. ⚠️ **AP mode has no authentication**
|
||||
**Severity:** HIGH
|
||||
**File:** [config.h](include/config.h#L82), [web_server.cpp](src/web_server.cpp#L115)
|
||||
**Issue:**
|
||||
```cpp
|
||||
constexpr bool WEB_AUTH_REQUIRE_AP = false; // AP mode has NO authentication!
|
||||
```
|
||||
When device acts as an access point, all endpoints can be accessed without any authentication.
|
||||
|
||||
**Impact:** Any device that connects to the AP can access all functionality:
|
||||
- Download meter data and history
|
||||
- Change WiFi/MQTT configuration
|
||||
- Change web UI credentials
|
||||
- Affect system behavior
|
||||
|
||||
**Recommendation:**
|
||||
- Require authentication even in AP mode
|
||||
- Or implement a time-limited "setup mode" that requires initial password setup
|
||||
- Display a prominent warning on AP mode UI
|
||||
|
||||

|
||||
|
||||
### 4. ⚠️ **Integer overflow potential in history bin allocation**
|
||||
**Severity:** MEDIUM
|
||||
**File:** [web_server.cpp](src/web_server.cpp#L767)
|
||||
**Code:**
|
||||
```cpp
|
||||
uint32_t bins = (static_cast<uint32_t>(days) * 24UL * 60UL) / res_min;
|
||||
if (bins == 0 || bins > SD_HISTORY_MAX_BINS) {
|
||||
// error handling...
|
||||
return;
|
||||
}
|
||||
```
|
||||
|
||||
**Issue:** While bounds checks are in place, the multiplication `days * 24 * 60` uses 32-bit math after casting. Although mitigated by `SD_HISTORY_MAX_DAYS = 30` and `SD_HISTORY_MIN_RES_MIN = 1`, the order of operations could be unsafe with different constants.
|
||||
|
||||
**Current Safety:** The bounds check at [L776](src/web_server.cpp#L776) prevents allocation of more than 4000 bins. Max days (30) × 24 × 60 = 43,200 bins, but then divided by res_min (minimum 1), result is capped at 4000.
|
||||
|
||||
**Recommendation:**
|
||||
- Reorder the multiplication to avoid overflow: `((days * 24) * 60) / res_min` → safer to do: `(days / res_min_in_days) * minutes_per_day` to prevent intermediate overflow
|
||||
- Or explicitly check: `if (days > UINT32_MAX / (24 * 60)) { error; }`
|
||||
|
||||
---
|
||||
|
||||
### 5. ⚠️ **Potential memory leak in history processing on error**
|
||||
**Severity:** MEDIUM
|
||||
**File:** [web_server.cpp](src/web_server.cpp#L779)
|
||||
**Code:**
|
||||
```cpp
|
||||
g_history.bins = new (std::nothrow) HistoryBin[bins];
|
||||
if (!g_history.bins) {
|
||||
g_history.error = true;
|
||||
g_history.error_msg = "oom";
|
||||
server.send(200, "application/json", "{\"ok\":false,\"error\":\"oom\"}");
|
||||
return;
|
||||
}
|
||||
```
|
||||
|
||||
**Issue:** If a new history request is made while a previous request has error state with allocated `g_history.bins`, the `history_reset()` function properly cleans up. However, if the device loses power or crashes between allocation and cleanup, memory isn't freed (minor issue, but worth noting on embedded system).
|
||||
|
||||
**Mitigation:** The [history_reset()](src/web_server.cpp#L268) function properly cleans up on next use.
|
||||
|
||||
**Recommendation:**
|
||||
- Ensure `history_reset()` is always called before allocating new bins ✅ Already done at [L781](src/web_server.cpp#L781)
|
||||
|
||||
---
|
||||
|
||||
## Medium Priority Issues
|
||||
|
||||
### 6. ⚠️ **String buffer size assumptions in CSV line parsing**
|
||||
**Severity:** MEDIUM
|
||||
**File:** [web_server.cpp](src/web_server.cpp#L298)
|
||||
**Code:**
|
||||
```cpp
|
||||
char line[160];
|
||||
size_t n = g_history.file.readBytesUntil('\n', line, sizeof(line) - 1);
|
||||
line[n] = '\0';
|
||||
```
|
||||
|
||||
**Issue:** If SD card contains a line longer than 160 bytes (minus 1 for null terminator), the function will silently truncate data and re-attempt. The CSV data format is expected to be compact, but if corrupted files exist, this could cause parsing failures.
|
||||
|
||||
**Mitigation:** The function gracefully handles parse failures with `if (!history_parse_line(line, ts, p)) { continue; }` and returns false on oversized fields at [L323](src/web_server.cpp#L323).
|
||||
|
||||
**Recommendation:**
|
||||
- This is acceptable for the use case. Consider logging truncation warnings if SERIAL_DEBUG_MODE is enabled.
|
||||
|
||||
---
|
||||
|
||||
### 7. ⚠️ **CSV injection vulnerability in meter data logging**
|
||||
**Severity:** MEDIUM (Low practical risk)
|
||||
**File:** [sd_logger.cpp](src/sd_logger.cpp#L107)
|
||||
**Code:**
|
||||
```cpp
|
||||
f.print(data.total_power_w, 1); // Directly prints floating point
|
||||
f.print(data.energy_total_kwh, 3);
|
||||
```
|
||||
|
||||
**Issue:** If floating-point values could be controlled by attacker, they could potentially inject CSV/formula injection attacks (e.g., `=1+1` starts formula in Excel). The power_w values are calculated from meter readings, so this has LOW practical risk.
|
||||
|
||||
**Impact:** Low - values come from trusted LoRa devices, not user input
|
||||
**Recommendation:**
|
||||
- If you want to be extra safe, sanitize by checking first character: if value starts with `=`, `+`, `@`, or `-`, prefix with single quote or space
|
||||
- For now, this is acceptable given the trusted data source
|
||||
|
||||
---
|
||||
|
||||
## Low Priority Issues / Best Practice Recommendations
|
||||
|
||||
### 8. ℹ️ **Path construction could use better validation**
|
||||
**Severity:** LOW
|
||||
**File:** [web_server.cpp](src/web_server.cpp#L179)
|
||||
**Code:**
|
||||
```cpp
|
||||
static bool sanitize_sd_download_path(String &path, String &error) {
|
||||
// ... checks for "..", "\", "//" ...
|
||||
if (!path.startsWith("/dd3/")) {
|
||||
error = "prefix";
|
||||
return false;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Assessment:** ✅ **Path traversal protection is GOOD**
|
||||
- Checks for `..` (parent directory)
|
||||
- Checks for `\` (backslash)
|
||||
- Checks for `//` (double slashes)
|
||||
- Requires `/dd3/` prefix
|
||||
- Limits path length to 160 characters
|
||||
|
||||
The implementation is solid. No changes needed.
|
||||
|
||||
---
|
||||
|
||||
### 9. ℹ️ **HTML escaping is properly implemented**
|
||||
**Severity:** N/A
|
||||
**File:** [html_util.cpp](src/html_util.cpp)
|
||||
**Assessment:** ✅ **XSS protection is GOOD**
|
||||
```cpp
|
||||
case '&': out += "&"; break;
|
||||
case '<': out += "<"; break;
|
||||
case '>': out += ">"; break;
|
||||
case '"': out += """; break;
|
||||
case '\'': out += "'"; break;
|
||||
```
|
||||
|
||||
All unsafe HTML characters are properly escaped. Good defensive programming.
|
||||
|
||||
---
|
||||
|
||||
### 10. ℹ️ **Buffer overflow checks are generally sound**
|
||||
**Severity:** N/A
|
||||
**Files:** [meter_driver.cpp](src/meter_driver.cpp), [lora_transport.cpp](src/lora_transport.cpp)
|
||||
**Assessment:** ✅ **NO UNSAFE STRING FUNCTIONS FOUND**
|
||||
|
||||
- No `strcpy`, `strcat`, `sprintf`, `gets`, `scanf` used
|
||||
- All buffer writes check bounds before writing
|
||||
- Example from [meter_driver.cpp L50](src/meter_driver.cpp#L50):
|
||||
```cpp
|
||||
if (n + 1 < sizeof(num_buf)) { // Bounds check BEFORE write
|
||||
num_buf[n++] = c;
|
||||
}
|
||||
```
|
||||
|
||||
- Example from [lora_transport.cpp L119](src/lora_transport.cpp#L119):
|
||||
```cpp
|
||||
if (pkt.payload_len > LORA_MAX_PAYLOAD) {
|
||||
return false; // Reject oversized payloads
|
||||
}
|
||||
memcpy(&buffer[idx], pkt.payload, pkt.payload_len);
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 11. ℹ️ **Zigzag encoding is correct**
|
||||
**Severity:** N/A
|
||||
**File:** [payload_codec.cpp](src/payload_codec.cpp#L107)
|
||||
**Code:**
|
||||
```cpp
|
||||
uint32_t zigzag32(int32_t x) {
|
||||
return (static_cast<uint32_t>(x) << 1) ^ static_cast<uint32_t>(x >> 31);
|
||||
}
|
||||
```
|
||||
|
||||
**Assessment:** ✅ **CORRECT**
|
||||
- Proper cast to uint32_t before shift avoids UB
|
||||
- Standard protobuf zigzag encoding pattern
|
||||
- Correctly handles signed integers
|
||||
|
||||
---
|
||||
|
||||
### 12. ℹ️ **Payload encoding/decoding has solid bounds checking**
|
||||
**Severity:** N/A
|
||||
**File:** [payload_codec.cpp](src/payload_codec.cpp#L132-160)
|
||||
**Assessment:** ✅ **GOOD DEFENSIVE PROGRAMMING**
|
||||
|
||||
Examples of proper bounds checks:
|
||||
```cpp
|
||||
// Check maximum samples
|
||||
if (in.n > kMaxSamples) return false;
|
||||
|
||||
// Check feature mask validity
|
||||
if ((in.present_mask & ~kPresentMaskValidBits) != 0) return false;
|
||||
|
||||
// Check consistency
|
||||
if (bit_count32(in.present_mask) != in.n) return false;
|
||||
|
||||
// Check monotonically increasing energy
|
||||
if (in.energy_wh[i] < in.energy_wh[i - 1]) return false;
|
||||
|
||||
// Check for 32-bit overflow when adding deltas
|
||||
uint64_t sum = static_cast<uint64_t>(out->energy_wh[i-1]) + delta;
|
||||
if (sum > UINT32_MAX) return false;
|
||||
|
||||
// Check phase value ranges
|
||||
if (value < INT16_MIN || value > INT16_MAX) return false;
|
||||
```
|
||||
|
||||
Excellent work on defense-in-depth.
|
||||
|
||||
---
|
||||
|
||||
### 13. ℹ️ **LoRa frame validation is robust**
|
||||
**Severity:** N/A
|
||||
**File:** [lora_transport.cpp](src/lora_transport.cpp#L126-180)
|
||||
**Assessment:** ✅ **GOOD**
|
||||
|
||||
- Validates minimum packet size
|
||||
- Validates maximum packet size
|
||||
- CRC verification
|
||||
- Message kind validation
|
||||
- Signal strength logging
|
||||
|
||||
---
|
||||
|
||||
### 14. ⚠️ **Time-based security: Minimum epoch check**
|
||||
**Severity:** LOW
|
||||
**File:** [config.h](include/config.h#L81)
|
||||
**Code:**
|
||||
```cpp
|
||||
constexpr uint32_t MIN_ACCEPTED_EPOCH_UTC = 1769904000UL; // 2026-02-01 00:00:00 UTC
|
||||
```
|
||||
|
||||
**Issue:** This constant is a static minimum and won't be appropriate over time. In 2030, this will reject legitimate timestamps from 2026-2029.
|
||||
|
||||
**Recommendation:**
|
||||
- Calculate dynamically: `MIN_ACCEPTED_EPOCH = compile_time_epoch - 5_years`
|
||||
- Or use a configuration that can be updated via firmware
|
||||
- Or accept any reasonable recent timestamp (e.g., >= 2020-01-01)
|
||||
|
||||
---
|
||||
|
||||
### 15. ℹ️ **Floating point NaN handling is correct**
|
||||
**Assessment:** ✅ **GOOD**
|
||||
|
||||
The code properly uses `isnan()` throughout:
|
||||
- [json_codec.cpp L13](src/json_codec.cpp#L13)
|
||||
- [web_server.cpp L104](src/web_server.cpp#L104)
|
||||
- [sd_logger.cpp L131](src/sd_logger.cpp#L131)
|
||||
|
||||
No integer division by zero issues detected either (checks for zero before division).
|
||||
|
||||
---
|
||||
|
||||
### 16. ℹ️ **Integer casting for power calculations handles overflow**
|
||||
**Severity:** N/A
|
||||
**File:** [web_server.cpp](src/web_server.cpp#L97)
|
||||
**Code:**
|
||||
```cpp
|
||||
static int32_t round_power_w(float value) {
|
||||
if (isnan(value)) return 0;
|
||||
long rounded = lroundf(value);
|
||||
if (rounded > INT32_MAX) return INT32_MAX; // Overflow protection
|
||||
if (rounded < INT32_MIN) return INT32_MIN; // Underflow protection
|
||||
return static_cast<int32_t>(rounded);
|
||||
}
|
||||
```
|
||||
|
||||
**Assessment:** ✅ **EXCELLENT** - Defensive against both positive and negative overflows
|
||||
|
||||
---
|
||||
|
||||
## Summary Table
|
||||
|
||||
| ID | Issue | Severity | Category | Status |
|
||||
|---|---|---|---|---|
|
||||
| 1 | No HTTPS/TLS | CRITICAL | Security | ⚠️ Needs Fix |
|
||||
| 2 | Weak default credentials | HIGH | Security | ⚠️ Needs Fix |
|
||||
| 3 | AP mode no auth | HIGH | Security | ⚠️ Needs Fix |
|
||||
| 4 | Integer overflow in bins | MEDIUM | Memory | ⚠️ Needs Review |
|
||||
| 5 | Memory leak potential | MEDIUM | Memory | ✅ Mitigated |
|
||||
| 6 | CSV line truncation | MEDIUM | Data Handling | ✅ Safe |
|
||||
| 7 | CSV injection | MEDIUM | Security | ✅ Low Risk |
|
||||
| 8 | Path traversal | LOW | Security | ✅ Well Protected |
|
||||
| 9-16 | Best practices | N/A | Quality | ✅ GOOD |
|
||||
|
||||
---
|
||||
|
||||
## Recommendations for Fixes
|
||||
|
||||
### Immediate (Critical Path)
|
||||
1. **Enable HTTPS** - Implement TLS on ESP32 web server
|
||||
2. **Strengthen AP mode security** - Either enable auth or use time-limited setup mode
|
||||
3. **Improve default credentials** - Generate strong defaults or force user configuration
|
||||
|
||||
### Short-term (High Priority)
|
||||
4. **Fix integer overflow checks** - Add explicit overflow detection before bin allocation
|
||||
5. **Document security limitations** - Clearly state that HTTPS is not available
|
||||
|
||||
### Long-term (Nice to Have)
|
||||
6. **Add audit logging** - Log all configuration changes and data access
|
||||
7. **Implement certificate pinning** - Once HTTPS is added
|
||||
8. **Add device firmware signature verification** - Prevent unauthorized updates
|
||||
|
||||
---
|
||||
|
||||
## Testing Recommendations
|
||||
|
||||
```bash
|
||||
# Verify no plaintext credentials in traffic
|
||||
tcpdump -i <interface> port 80 or port 1883 | grep -i password
|
||||
|
||||
# Test path traversal protection
|
||||
curl "http://device/sd/download?path=/etc/passwd"
|
||||
curl "http://device/sd/download?path=/../../../"
|
||||
|
||||
# Test XSS protection
|
||||
curl "http://device/sender/<img%20src=x%20onerror=alert(1)>"
|
||||
|
||||
# Test OOM handling with large history requests
|
||||
curl "http://device/history/start?days=365&res=1"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Overall Assessment
|
||||
|
||||
**Grade: B+ (Good with areas for improvement)**
|
||||
|
||||
**Strengths:**
|
||||
- Solid use of safe APIs and standard library functions
|
||||
- Excellent bounds checking throughout
|
||||
- Good defensive programming practices
|
||||
- CRC validation and format validation
|
||||
|
||||
**Weaknesses:**
|
||||
- Lack of encryption (HTTPS)
|
||||
- Weak default security posture
|
||||
- No security in AP mode
|
||||
- Need better overflow protection in integer arithmetic
|
||||
|
||||
The codebase demonstrates good engineering practices and would be production-ready once the critical HTTPS and authentication issues are addressed.

|
||||
#### Manual Mode (Always Available)
|
||||
- Enter start and end dates/times
|
||||
- Example: Start `2026-03-01` at `00:00:00`, End `2026-03-05` at `23:59:59`
|
||||
- Useful when you know exactly what data is missing
|
||||
|
||||
#### Auto-Detect Mode (Requires InfluxDB)
|
||||
- Automatically finds gaps in your InfluxDB data
|
||||
- Connect to your InfluxDB instance
|
||||
- Script will identify the oldest missing data range
|
||||
- Republish that range automatically
|
||||
|
||||
### Progress Tab
|
||||
Real-time status during publishing:
|
||||
- **Progress Bar**: Visual indication of publishing status
|
||||
- **Statistics**: Count of published/skipped samples, current rate
|
||||
- **Log Output**: Detailed logging of all actions
|
||||
|
||||
## Step-by-step Example
|
||||
|
||||
1. **Prepare CSV File**
|
||||
- Extract CSV file from SD card
|
||||
- Example path: `D:\dd3-F19C\2026-03-09.csv`
|
||||
|
||||
2. **Launch GUI**
|
||||
```bash
|
||||
python republish_mqtt_gui.py
|
||||
```
|
||||
|
||||
3. **Settings Tab**
|
||||
- Click "Browse..." and select the CSV file
|
||||
- Enter Device ID: `dd3-F19C`
|
||||
- MQTT Broker: `192.168.1.100` (or your broker address)
|
||||
- Test connection to verify MQTT is working
|
||||
|
||||
4. **Time Range Tab**
|
||||
- **Manual Mode**: Enter dates you want to republish
|
||||
- Start: `2026-03-09` / `08:00:00`
|
||||
- End: `2026-03-09` / `18:00:00`
|
||||
- **Or Auto-Detect**: Fill InfluxDB settings if available
|
||||
|
||||
5. **Progress Tab**
|
||||
- View real-time publishing progress
|
||||
- Watch the log for detailed status
|
||||
|
||||
6. **Start**
|
||||
- Click "Start Publishing" button
|
||||
- Monitor progress in real-time
|
||||
- Success message when complete
|
||||
|
||||
## Tips
|
||||
|
||||
### CSV File Location
|
||||
On Windows with SD card reader:
|
||||
- Drive letter shows up (e.g., `D:\`)
|
||||
- Path is usually: `D:\dd3\[DEVICE-ID]\[DATE].csv`
|
||||
|
||||
On Linux with SD card:
|
||||
- Example: `/mnt/sd/dd3/dd3-F19C/2026-03-09.csv`
|
||||
|
||||
### Finding Device ID
|
||||
- Displayed on device's OLED screen
|
||||
- Also in CSV directory names on SD card
|
||||
- Format: `dd3-XXXX` where XXXX is hex device short ID
|
||||
|
||||
### Rate Limiting
|
||||
- **Conservative** (1-2 msg/sec): For unreliable networks or busy brokers
|
||||
- **Default** (5 msg/sec): Recommended, safe for most setups
|
||||
- **Fast** (10+ msg/sec): Only if you know your broker can handle it
|
||||
|
||||
### InfluxDB Auto-Detect
|
||||
Requires:
|
||||
- InfluxDB running and accessible
|
||||
- Valid API token
|
||||
- Correct organization and bucket names
|
||||
- Data already stored in InfluxDB bucket
|
||||
|
||||
If InfluxDB unavailable: Fall back to manual time selection
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### "Could not connect to MQTT broker"
|
||||
- Check broker address and port
|
||||
- Verify firewall allows connection
|
||||
- Check if broker is running
|
||||
- Try "Test Connection" button
|
||||
|
||||
### "CSV file not found"
|
||||
- Verify file path is correct
|
||||
- Try re-selecting file with Browse button
|
||||
- Ensure file is readable
|
||||
|
||||
### "0 samples published"
|
||||
- Time range may not match CSV data
|
||||
- Try wider time range
|
||||
- Check CSV file contains data
|
||||
- Verify timestamps are Unix format
|
||||
|
||||
### "InfluxDB connection error"
|
||||
- Check InfluxDB URL is running
|
||||
- Verify API token is valid
|
||||
- Check organization and bucket name
|
||||
- Try accessing InfluxDB web UI manually
|
||||
|
||||
### GUI is slow or unresponsive
|
||||
- This is normal during MQTT publishing
|
||||
- GUI updates in background
|
||||
- Wait for operation to complete
|
||||
- Check Progress tab for live updates
|
||||
|
||||
## Keyboard Shortcuts
|
||||
- Tab: Move to next field
|
||||
- Enter: Start publishing from most tabs
|
||||
- Ctrl+C: Exit (if launched from terminal)
|
||||
|
||||
## File Structure
|
||||
|
||||
```
|
||||
republish_mqtt.py → Command-line version
|
||||
republish_mqtt_gui.py → GUI version (this)
|
||||
requirements_republish.txt → Python dependencies
|
||||
REPUBLISH_README.md → Full documentation
|
||||
```
|
||||
|
||||
Use the **GUI** if you prefer point-and-click interface.
|
||||
Use the **CLI** if you want to automate or run in scripts.
|
||||
|
||||
## Platform Support
|
||||
|
||||
✓ **Windows 10/11** - Native support
|
||||
✓ **macOS** - Works with Python 3.7+
|
||||
✓ **Linux** (Ubuntu, Debian, Fedora) - Works with Python 3.7+
|
||||
|
||||
All platforms use tkinter (included with Python).
|
||||
|
||||
## Performance
|
||||
|
||||
Typical times on a standard PC:
|
||||
- 1 day of data (~2800 samples): ~9-10 minutes at 5 msg/sec
|
||||
- 1 week of data (~19,600 samples): ~65 minutes at 5 msg/sec
|
||||
|
||||
Time = (Number of Samples) / (Rate in msg/sec)

# DD3 MQTT Data Republisher
|
||||
|
||||
Standalone Python script to recover and republish lost meter data from SD card CSV files to MQTT.
|
||||
|
||||
## Features
|
||||
|
||||
- **Rate-limited publishing**: Sends 5 messages/second by default (configurable) to prevent MQTT broker overload
|
||||
- **Two modes of operation**:
|
||||
- **Auto-detect**: Connect to InfluxDB to find gaps in recorded data
|
||||
- **Manual selection**: User specifies start/end time range
|
||||
- **Cross-platform**: Works on Windows, macOS, and Linux
|
||||
- **CSV parsing**: Reads SD card CSV export format and converts to MQTT JSON
|
||||
- **Interactive mode**: Walks user through configuration step-by-step
|
||||
- **Command-line mode**: Scripting and automation friendly
|
||||
|
||||
## Installation
|
||||
|
||||
### Prerequisites
|
||||
- Python 3.7 or later
|
||||
|
||||
### Setup
|
||||
|
||||
```bash
|
||||
# Install dependencies
|
||||
pip install -r requirements_republish.txt
|
||||
```
|
||||
|
||||
### Optional: InfluxDB support
|
||||
To enable automatic gap detection via InfluxDB, `influxdb-client` will be automatically installed. If you want to use the fallback manual mode only, you can skip this (though it's included in requirements).
|
||||
|
||||
## Usage
|
||||
|
||||
### Interactive Mode (Recommended for first use)
|
||||
|
||||
```bash
|
||||
python republish_mqtt.py -i
|
||||
```
|
||||
|
||||
The script will prompt you for:
|
||||
1. CSV file location (with auto-discovery)
|
||||
2. Device ID
|
||||
3. MQTT broker settings
|
||||
4. Time range (manual or auto-detect from InfluxDB)
|
||||
|
||||
### Command Line Mode
|
||||
|
||||
#### Republish a specific time range:
|
||||
```bash
|
||||
python republish_mqtt.py \
|
||||
-f path/to/data.csv \
|
||||
-d dd3-F19C \
|
||||
--mqtt-broker 192.168.1.100 \
|
||||
--mqtt-user admin \
|
||||
--mqtt-pass password \
|
||||
--from-time "2026-03-01" \
|
||||
--to-time "2026-03-05"
|
||||
```
|
||||
|
||||
#### Auto-detect missing data with InfluxDB:
|
||||
```bash
|
||||
python republish_mqtt.py \
|
||||
-f path/to/data.csv \
|
||||
-d dd3-F19C \
|
||||
--mqtt-broker 192.168.1.100 \
|
||||
--influxdb-url http://localhost:8086 \
|
||||
--influxdb-token mytoken123 \
|
||||
--influxdb-org myorg \
|
||||
--influxdb-bucket smartmeter
|
||||
```
|
||||
|
||||
#### Different publish rate (slower for stability):
|
||||
```bash
|
||||
python republish_mqtt.py \
|
||||
-f data.csv \
|
||||
-d dd3-F19C \
|
||||
--mqtt-broker localhost \
|
||||
--rate 2 # 2 messages per second instead of 5
|
||||
```
|
||||
|
||||
## CSV Format
|
||||
|
||||
The script expects CSV files exported from the SD card with this header:
|
||||
```
|
||||
ts_utc,ts_hms_utc,p_w,p1_w,p2_w,p3_w,e_kwh,bat_v,bat_pct,rssi,snr,err_m,err_d,err_tx,err_last
|
||||
```
|
||||
|
||||
Each row is one meter sample. The script converts these to MQTT JSON format:
|
||||
```json
|
||||
{
|
||||
"id": "F19C",
|
||||
"ts": 1710076800,
|
||||
"e_kwh": "1234.56",
|
||||
"p_w": 5432,
|
||||
"p1_w": 1800,
|
||||
"p2_w": 1816,
|
||||
"p3_w": 1816,
|
||||
"bat_v": "4.15",
|
||||
"bat_pct": 95,
|
||||
"rssi": -95,
|
||||
"snr": 9.25
|
||||
}
|
||||
```
|
||||
|
||||
## How It Works
|
||||
|
||||
### Manual Mode (Fallback)
|
||||
1. User specifies a time range (start and end timestamps)
|
||||
2. Script reads CSV file
|
||||
3. Filters samples within the time range
|
||||
4. Publishes to MQTT topic: `smartmeter/{device_id}/state`
|
||||
5. Respects rate limiting (5 msg/sec by default)
|
||||
|
||||
### Auto-Detect Mode (with InfluxDB)
|
||||
1. Script connects to InfluxDB
|
||||
2. Queries for existing data in the specified bucket
|
||||
3. Identifies gaps (time ranges with no data)
|
||||
4. Shows gaps to user
|
||||
5. Republishes the first (oldest) gap from CSV file
|
||||
6. User can re-run to fill subsequent gaps
|
||||
|
||||
## Rate Limiting
|
||||
|
||||
By default, the script publishes 5 messages per second. This is:
|
||||
- **Safe for most MQTT brokers** (no risk of overload)
|
||||
- **Fast enough** (fills data in < 5 minute for typical daily data)
|
||||
- **Adjustable** with `--rate` parameter
|
||||
|
||||
Examples:
|
||||
- `--rate 1`: 1 msg/sec (very conservative)
|
||||
- `--rate 5`: 5 msg/sec (default, recommended)
|
||||
- `--rate 10`: 10 msg/sec (only if broker can handle it)
|
||||
|
||||
## Device ID
|
||||
|
||||
The device ID is used to determine the MQTT topic. It appears on the device display and in the CSV directory structure:
|
||||
- Example: `dd3-F19C`
|
||||
- Short ID (last 4 characters): `F19C`
|
||||
|
||||
You can use either form; the script extracts the short ID for the MQTT topic.
|
||||
|
||||
## Time Format
|
||||
|
||||
Dates can be specified in multiple formats:
|
||||
- `2026-03-01` (YYYY-MM-DD)
|
||||
- `2026-03-01 14:30:00` (YYYY-MM-DD HH:MM:SS)
|
||||
- `14:30:00` (HH:MM:SS - uses today's date)
|
||||
- `14:30` (HH:MM - uses today's date)
|
||||
|
||||
## Examples
|
||||
|
||||
### Scenario 1: Recover data from yesterday
|
||||
```bash
|
||||
python republish_mqtt.py -i
|
||||
# Select CSV file → dd3-F19C_2026-03-09.csv
|
||||
# Device ID → dd3-F19C
|
||||
# MQTT broker → 192.168.1.100
|
||||
# Choose manual time selection
|
||||
# From → 2026-03-09 00:00:00
|
||||
# To → 2026-03-10 00:00:00
|
||||
```
|
||||
|
||||
### Scenario 2: Find and fill gaps automatically
|
||||
```bash
|
||||
python republish_mqtt.py \
|
||||
-f path/to/csv/dd3-F19C/*.csv \
|
||||
-d dd3-F19C \
|
||||
--mqtt-broker mosquitto.example.com \
|
||||
--mqtt-user admin --mqtt-pass changeme \
|
||||
--influxdb-url http://influxdb:8086 \
|
||||
--influxdb-token mytoken \
|
||||
--influxdb-org myorg
|
||||
```
|
||||
|
||||
### Scenario 3: Slow publishing for unreliable connection
|
||||
```bash
|
||||
python republish_mqtt.py -i --rate 1
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### "Cannot connect to MQTT broker"
|
||||
- Check broker address and port
|
||||
- Verify firewall rules
|
||||
- Check username/password if required
|
||||
- Test connectivity: `ping broker_address`
|
||||
|
||||
### "No data in CSV file"
|
||||
- Verify CSV file path exists
|
||||
- Check that CSV has data rows (not just header)
|
||||
- Ensure device ID matches CSV directory name
|
||||
|
||||
### "InfluxDB query error"
|
||||
- Verify InfluxDB is running and accessible
|
||||
- Check API token validity
|
||||
- Verify organization name
|
||||
- Check bucket contains data
|
||||
|
||||
### "Published 0 samples"
|
||||
- CSV file may be empty
|
||||
- Time range may not match any data in CSV
|
||||
- Try a wider date range
|
||||
- Check that CSV timestamps are in Unix format
|
||||
|
||||
## Performance
|
||||
|
||||
Typical performance on a standard PC:
|
||||
- **CSV parsing**: ~10,000 rows/second
|
||||
- **MQTT publishing** (at 5 msg/sec): 1 day's worth of data (~2800 samples) takes ~9 minutes
|
||||
|
||||
For large files (multiple weeks of data), the script may take longer. This is expected and safe.
|
||||
|
||||
## Advanced: Scripting
|
||||
|
||||
For automation, you can use command-line mode with environment variables or config files:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Recover last 3 days of data
|
||||
|
||||
DEVICE_ID="dd3-F19C"
|
||||
CSV_DIR="/mnt/sd/dd3/$DEVICE_ID"
|
||||
FROM=$(date -d '3 days ago' '+%Y-%m-%d')
|
||||
TO=$(date '+%Y-%m-%d')
|
||||
|
||||
python republish_mqtt.py \
|
||||
-f "$(ls -t $CSV_DIR/*.csv | head -1)" \
|
||||
-d "$DEVICE_ID" \
|
||||
--mqtt-broker mqtt.example.com \
|
||||
--mqtt-user admin \
|
||||
--mqtt-pass changeme \
|
||||
--from-time "$FROM" \
|
||||
--to-time "$TO" \
|
||||
--rate 5
|
||||
```
