+## Alternative Messaging System
+
+Since Signal bridge requires phone access, an alternative messaging system has been implemented using Home Assistant Matrix integration:
+
+### Matrix Messaging Commands
+- **Send messages**: `python scripts/claude-messaging-system.py send "message"`
+- **Read messages**: `python scripts/claude-messaging-system.py read`
+- **Monitor messages**: `python scripts/claude-messaging-system.py monitor`
+- **Send notifications**: `python scripts/claude-messaging-system.py notify "message"`
+
+### Home Assistant Integration
+- **Room**: `!xZkScMybPseErYMJDz:matrix.klas.chat`
+- **Access**: Available through Home Assistant Matrix room
+- **Real-time**: Supports real-time communication without Signal app
+
