The Schneider Electric LSS100100 (Wiser for KNX, formerly homeLYnk) is a DIN-rail logic controller that visualises, controls, and manages KNX installations while bridging KNX, Modbus RTU/TCP, and BACnet. It acts as gateway, data logger, and event controller for residential and light-commercial smart buildings.

WEB SCADA pages run on PC, smartphone, and tablet — visualisations can be generated with EConfigure KNX Lite. The controller exposes up to 150 BACnet points (B-ASC certified), supports eight user logins, and connects via KNX TP, Ethernet, RS-485 (Modbus), RS-232, and USB 2.0. Power is 24 V DC (approx. 2 W). Size the KNX segment with MTN684064 or MTN6513-1202; for larger commercial sites consider LSS100200 SpaceLYnk.

Key Features — Multi-Protocol Logic Controller

Applications and KNX Integration

• Smart homes: Centralise KNX lighting, HVAC, and metering with mobile visualisation; extend lines with MTN6500-0101 couplers.
• Energy management: Log consumption from MTN6600-0603 meters and trigger load shedding via MTN6700 actuators.
• Modbus HVAC: Bridge boiler or chiller Modbus devices to KNX room controllers such as MTN6212.
• Remote commissioning: Pair with MTN6502-0105 IP interface or MTN6500-0103 IP router for ETS access over LAN.
• DALI lighting: Control DALI luminaires through KNX gateways such as MTN6725-0003.

Choosing Wiser vs SpaceLYnk

Use LSS100100 for residential and small commercial projects needing KNX visualisation, Modbus/BACnet bridging, and up to eight users. For larger BACnet capacity (500 points), DALI/SSL support, and up to 50 users, choose LSS100200 SpaceLYnk.
