System Overview
System Role: Wall-mounted 4-inch smart gateway panel with voice intercom. Centralises Bluetooth Mesh network, Wi-Fi 2.4G+5G cloud bridge, and 4-channel relay load control in a single 86-type wall module.
Protocol Stack: Bluetooth 5.0 SIG Mesh (device mesh) · Wi-Fi 2.4G+5G dual-band (gateway / cloud) · BLE 5.2 (direct Bluetooth LE)
Load Control: 4 independent relay channels. Routes DALI / DMX / 0-10V commands to Bluetooth Mesh-connected driver modules across all zones.
Scene & Scheduling: Local scene storage · Time-based circadian scheduling · Night mode auto-trigger · Voice command via built-in microphone array.
Installation: 86-type wall box mount; 172 × 86 mm panel format.
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.
