Alysh Smart Home BAS architecture integrates KNX automation, DALI lighting control, Samsung VRF HVAC, IP security cameras, and Zigbee smart locks across entry and rooms floors with centralized Home Assistant cloud control. Data flows from field devices (touch panels, thermostats, presence sensors) through KNX buses and line couplers to actuators (shutter controllers, relay boards, DALI gateways) and VRF gateways, with Ethernet backbone connecting security switches, media systems, and remote access. This multi-protocol design demonstrates enterprise-grade residential automation balancing reliability, scalability, and future expansion through prepared stub lines and modular gateway architecture. Fork this diagram on Diagrams.so to customize device counts, add additional floors, or adapt the control topology for your specific property layout and automation requirements. The UPS-backed network infrastructure and segregated switches (data, security, media) reflect best practices for resilient smart home systems requiring 24/7 availability.
