Interface 4

The 4-inch Touch Control Panel is a wall-mounted smart home interface that doubles as a built-in Zigbee gateway. It fits a standard switch position — the same 86mm footprint — and provides an always-on touchscreen for controlling devices, triggering scenes, checking sensor states, and issuing voice commands. Unlike a phone, it never needs unlocking, never runs out of battery, and never leaves the room. The built-in Zigbee coordinator means this panel can serve as the primary hub for a small to mid-size installation. Devices pair directly to it, scenes are configured on its interface, and automations run locally without depending on cloud services or a separate hub device. For larger homes, it functions as a room-level control point connected to a central system. The touchscreen displays room status at a glance — which lights are on, what temperature the AC is set to, whether the front door sensor is open — and responds to taps for immediate control. Powered directly from mains voltage (100-240V AC) and connecting over Wi-Fi and Zigbee, the 4-inch panel is suited to bedrooms, kitchens, and hallways where a dedicated control surface eliminates the friction of phone-based smart home interaction. It integrates with the full TAC switch ecosystem and supports voice assistant functionality for hands-free operation.
