Convenient. Fan turns on when to much moisture is

[This review was collected as part of a promotion.] I received this Lutron humidity sensor switch for my bathroom exhaust fan from Influenster. It took roughly 25 minutes for installation. Was pretty straight forward with the instructions provided. The switch is very convenient to reduce moisture and to prevent mold from growing. The switch comes with a moisture sensor level button you will want to set before attaching to cover back to the wall.

Convenient to use, easy to install!

[This review was collected as part of a promotion.] This XactSense Humidity Sensor Switch from Lutron has been a useful addition to our main bathroom. Our exhaust fan is on it's own switch, and this XactSense humidity sensor is able to automatically control the ventilation based on humidity levels, making for a convenient solution for keeping moisture under control. Installation the switch was straightforward, but I recommend hiring a professional if you are uncomfortable with electrical work. This switch does not require a neutral wire, which is nice for those without one available. The humidity sensor quickly responds to rising humidity levels to turn on the exhaust fan, and turns if off after a user-selectable timeout setting. You are able to easily adjust the timeout period as well as manually override operation to turn on your exhaust fan. I like how this switch automatically turns the exhaust fan on and off, without any user input. Overall, I recommend this humidity sensor switch for anyone wanting to simplify operation of their bathroom exhaust fan. It has been extremely convenient, and has even saved energy as we no longer need to remember to turn the exhaust vent off.

Easy install, great addition to our exhaust fans!

[This review was collected as part of a promotion.] This product was super easy to install and has provided good information in our bathroom! It was very compatible with the switch we already had. We have a small bathroom with not a lot of air flow and this helps us track the possibility of mold exposure.
