Research Notes
1. Overview
The BTicino (Legrand group) K4001C is a connected one-way switch from the Living Now European wiring line — a 1-module smart light switch that enables remote and voice-controlled lighting as part of the Living Now with Netatmo ("Home + Control") ecosystem, which uses Zigbee 3.0. It switches a 230 V load (≈2.2 A / up to ~500 W lighting), installs in a standard Italian/European wall box, and takes Living Now's interchangeable cover finishes (White, Black, Sand, and customizable). It integrates with the BTicino/Netatmo app, and — via the Netatmo gateway — Apple HomeKit, Amazon Alexa, and Google. (This is the European counterpart to Legrand's US adorne-with-Netatmo line; here Zigbee 3.0 is the correct protocol.)
2. User Sentiment
Living Now is praised for its modern, minimalist Italian design (the distinctive rectangular modules and premium finishes) and clean smart integration. As a "connected" module it adds app/voice/remote control and scenes to standard-looking switches. Considerations: it needs the Living Now with Netatmo gateway/ecosystem, it's a European wiring system (not US), and full smart features depend on that stack.
3. Real-World Applications
Smart one-way lighting control in European homes — local button plus app/voice/remote control, scheduling, and scenes within the Living Now with Netatmo system.
4. Technical Specifications

- Load: 230 V, ~2.2 A (≈ up to 500 W lighting)

5. Ordering & Compatibility
Requires the Living Now with Netatmo system (gateway/hub) for smart features; European wiring. Choose the matching Living Now cover finish/frame. The non-connected equivalent is K4001A (plain switch). Distinct from the US adorne/radiant with Netatmo line (different market/part numbers).
6. Known Issues
No notable reliability issues. Practical considerations: it needs the Living Now with Netatmo ecosystem/gateway, it's a European device, and voice/remote features depend on the Netatmo cloud/app stack.

Referência rápida de instalação
Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

Solução de problemas
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
