System Overview
System Role: Wall-mounted smart gateway centralising scene scheduling, spectrum timing, and device automation. Bridges Bluetooth 5.0 SIG Mesh to Ethernet/Wi-Fi for cloud and remote access.
Protocol Stack: Bluetooth 5.0 SIG Mesh · Wi-Fi 2.4G+5G · Ethernet (RJ45) · IR emitter
Lighting Protocol Compatibility: Drives LTECH wireless modules supporting DMX, DALI/0-10V, and Triac interfaces — enabling full coverage from constant-voltage to constant-current drivers across any zone.
Scene & Automation Engine: Supports multi-zone scene creation, time-based scheduling, and event automation (sensor triggers, IR appliance control) directly from the 4-inch touchscreen or via mobile app.
Direct Load Control: 2 independent relay channels rated LED ≤ 200 W / general load ≤ 400 W each — no separate relay module required for luminaire on/off switching.
Installation Format: 86-type wall box mount; compatible with 400+ panel frame combinations.
Network Capacity: Up to 300 devices per Bluetooth Mesh network — sufficient for full multi-floor commercial installations without secondary hub multiplication.
NFC Batch Programming: Tap a pre-configured NFC card to each driver or module to push network credentials and scene presets instantly. Eliminates app-by-app commissioning; a 20-fixture zone can be addressed in under 2 minutes.
OTA Firmware Upgrade: Over-the-air updates delivered via the LTECH Smart Life cloud. All devices in the mesh update sequentially; no technician site visit required.
