## Version 2.0.0 "Enhanced" (2025-12-20)
|
|
|
|
### 🎯 Overview
|
|
Enhanced version of the ESP32 Energy Meter project based on Giovanni Aggiustatutto's original work. This version adds significant improvements for reliability, user experience, and professional documentation.
|
|
|
|
### ✨ Major Enhancements
|
|
|
|
#### WiFi Connectivity Monitoring
|
|
- **Problem Solved**: Original `platform: status` caused false "disconnected" alerts
|
|
- **Solution**: Signal strength-based connection monitoring using `wifi_signal` sensor
|
|
- **Threshold**: -70 dBm connection threshold for accurate status
|
|
- **Benefits**: No more false positives, actual signal quality monitoring
|
|
|
|
#### OLED Burn-in Protection
|
|
- **Implementation**: Automatic screen clearing every 30 minutes
|
|
- **Method**: Time-based clearing using Home Assistant time synchronization
|
|
- **Safety**: Prevents permanent screen damage from static content
|
|
- **Configuration**: Easily customizable intervals
|
|
|
|
#### Professional Display Enhancement
|
|
- **Typography**: Google Fonts Baloo Bhaijaan 2 integration
|
|
- **Icons**: Material Symbols Outlined for WiFi status
|
|
- **Layout**: Optimized positioning for readability
|
|
- **Rotation**: 180° display rotation for optimal viewing
|
|
|
|
#### Performance Optimizations
|
|
- **Update Intervals**: Balanced 3-second sensor updates
|
|
- **Communication**: Optimized Modbus command throttling (50ms)
|
|

|
|
|
|
### 🔧 Technical Improvements
|
|
|
|
#### Enhanced WiFi Status Logic
|
|
```yaml
|
|
# OLD (caused false positives)
|
|
- platform: status
|
|
|
|
# NEW (accurate signal-based monitoring)
|
|
- platform: template
|
|
lambda: !lambda
|
|
return id(wifi_signal_strength).state > -70;
|
|
```
|
|
|
|
#### OLED Burn-in Protection
|
|
```yaml
|
|
# NEW: Automatic screen clearing
|
|
if (now % 1800 == 0) { // Every 30 minutes
|
|
it.clear();
|
|
return;
|
|
}
|
|
```
