The Inspinia INS4SQ is a 4″ square room controller for localized smart-home and building automation. Its 480 × 480 IPS touchscreen (400 cd/m², 5-point capacitive) provides in-room control of lighting, climate, and scenes while built-in temperature and humidity sensors feed automation logic.

Based on Linux 3.4 with the Inspinia application, the panel supports up to 1000 BMS points and 200 UI objects (200 BMS points on the initial license). Power is 24 V DC or PoE (802.3af) (max 5 W). One LAN port, one digital input, one 5 V digital output, and an add-on port accept optional KNX, Modbus, Zigbee, VRF, Bticino, or iNELS modules.

Key Features — Compact Room Interface

Applications and KNX Integration

• Hotel rooms and apartments: Per-room lighting, HVAC, and scene control with on-wall UI.
• KNX projects: Add the A-KNX module on the add-on port for KNX TP coupling to switches, actuators, and sensors.
• Larger UI elsewhere: Pair with INS8SQ 8″ or INS10SQ 10″ panels in common areas; use MNSRV Mini Server as DIN-rail logic head-end.
• Entry intercom: Integrate building entry via INS-SB24 or INS-K4A24 outdoor stations.

Choosing Inspinia SQ Touch Panels

The INS4SQ is the compact 4″ room controller when space and per-room licensing (200-point initial) are priorities. Step up to INS8SQ for an 8″ 1280 × 800 UI with more digital I/O and dual add-on ports (500-point initial license), or to INS10SQ for a 10″ panel with the same platform and 14 W PoE budget.
