Just released AmbiSense v5.1, a major update to my open-source ESP32-based motion-reactive LED lighting system. This version brings in support for multi-sensor setups, enabling synchronized lighting across L-shaped and U-shaped staircases — a feature that’s been requested quite a bit!
What’s New in v5.1:
🔹 Multi-Sensor Support via ESP-NOW
A flexible master-slave architecture now lets you span long or multi-level staircases with radar sensors at multiple locations.
🔹 Zone-Based Input Switching
Decide which sensor takes control using these new modes:
- Most Recent Activity
- Slave Priority
- Master Priority
- Zone-Based Auto-Switching (recommended for complex layouts)
🔹 Upgraded Web Interface
- Automatically detects connected slave nodes.
- Configure zones directly in the browser.
- Real-time diagnostics and network topology view.
🔹 Improved Diagnostics
- View live sensor and connection stats.
- Monitor ESP-NOW packet success rate, RSSI, and memory usage.
🔹 Enhanced LED Features
- Directional Trails for more realistic motion effects.
- Background Mode for subtle ambient lighting.
- Center Shift logic & LED strip validation to prevent misalignment.
🔹 Web UI Overhaul
- Fully mobile-responsive.
- Supports live updates with built-in input validation.
If you're working on staircase lighting or multi-zone motion-triggered LED projects, this update should simplify things quite a bit. Happy to hear feedback or help if you’re building your own setup.
