Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Meet the Lutron XactSense Humidity Sensor 3 amps Single Pole Bathroom Exhaust Smart-Enabled Switch in white — a moisture-aware upgrade designed to modernize your bathroom ventilation. This smart-enabled switch automatically engages your exhaust fan as humidity rises, helping prevent mold, foggy mirrors, and damp walls without you lifting a finger.

Why this switch stands out

  • Automatic humidity sensing — built-in sensing automatically powers the bathroom exhaust when moisture levels spike and quiets when humidity normalizes, keeping your space comfortable and healthier.
  • 3-amp, single-pole design — a compact, efficient solution suitable for standard bathroom fan loads while staying easy to install in a typical single-gang box.
  • Smart-enabled operation — beyond a basic on/off switch, this model offers intelligent control that reduces manual switching and supports modern home automation scenarios.
  • UL/CSA listed — trusted safety and compliance for residential use, giving you peace of mind with every cycle.
  • White finish, wall plate not included — a clean, neutral look that blends with most decors, while letting you reuse your existing wall plate for a seamless install.

Who is it for?

Ideal for powder rooms, family bathrooms, and any space where humidity can linger after showers or baths. If you want fewer foggy mirrors, less lingering dampness, and a hands-free solution that takes the guesswork out of bathroom ventilation, this switch is a smart fit.

How it works in real homes

Install it as a standard single-pole switch on the bathroom circuit. The sensor continuously monitors ambient moisture and automatically runs the exhaust fan to vent humidity, then turns the fan off once the air dries. It’s particularly helpful in bathrooms with slower natural ventilation or rooms that see heavy use but inconsistent airflow.

Tips for best results

  • Pair with a well-sized exhaust fan to maximize moisture removal without overworking the circuit.
  • Check local electrical codes during installation and consider professional installation if you’re not comfortable wiring a smart switch.
  • If you’re upgrading an existing setup, reuse your current wall plate or choose a compatible plate that matches your décor for a sleek, finished look.
