+# KNX Temperature Monitor Web Interface
+
+This directory contains two versions of the web interface for different WebSocket implementations:
+
+## 1. WebSocket with /ws prefix (index-ws.html)
+- Uses the standard HTTP port with a `/ws` path prefix for WebSocket connections
+- Suitable for ESP32 using standard WebServer
+- Files:
+  - `index-ws.html`: Main HTML file
+  - `script-ws.js`: WebSocket client implementation
+
+## 2. WebSocket on Port 81 (index-port81.html)
+- Uses a dedicated WebSocket server on port 81
+- Suitable for ESP8266 or when using AsyncWebServer
+- Files:
+  - `index-port81.html`: Main HTML file
+  - `script-port81.js`: WebSocket client implementation
+
+## Usage
+1. Choose the appropriate HTML file based on your ESP device and web server implementation:
+   - For standard WebServer with `/ws` prefix: Use `index-ws.html`
+   - For dedicated WebSocket server on port 81: Use `index-port81.html`
+2. Upload the corresponding files to your device's filesystem
+3. Access the web interface through your device's IP address
+
+Both versions provide the same functionality:
+- Real-time temperature display
+- Connection status indication
+- Automatic reconnection attempts
+- JSON message parsing
