Smart light switch won't pair — Elche, Valencian Community

A smart light switch that refuses to pair with your hub or Wi-Fi network leaves you unable to control lights through voice commands or automations. The problem often comes down to the switch requiring a neutral wire that isn't present in the box, a Z-Wave or Zigbee frequency conflict, firmware stuck mid-update, or the switch being too far from the hub or router. A smart-home installer verifies the wiring, checks protocol compatibility, updates firmware, positions repeaters or extenders if needed, and completes the pairing so the switch responds reliably.
