The Smart Alert Nightlight: How Many and Where?

November 20, 2014


One of the most common questions we’ve received from prospective Leeo users is a simple one: How many Smart Alert Nightlights should I buy? The answer is not so straightforward, because it depends on the layout of your home and the location of your smoke and carbon monoxide detectors. In this post, I’ll give a quick overview of things to consider when deciding where a Smart Alert Nightlight (or two, or three!) might fit into your home.


First, take a walk around your home and note the location of your smoke and carbon monoxide alarms. Since you don’t hear from them often, it’s easy to forget where they are. Then, take inventory of the available outlets near these alarms. The Smart Alert Nightlight is able to hear alarms sounding up to 75 feet away, but walls and closed doors can keep alarm sounds from reaching the nightlight and reduce its listening range. It’s also best to avoid placing the nightlight behind furniture or other large items, since the temperature and humidity sensor readings are most accurate with good airflow around the device. Many users choose to place the nightlight in a hallway, where it can detect alarms in several neighboring rooms — and also provide a little extra illumination in the middle of the night! An open, centrally located room is also a good place to consider.



For most homes, these guidelines mean that we recommend about one nightlight per floor of your home — unless your smoke and carbon monoxide alarms are all interconnected, in which case one nightlight will detect any alarm, regardless of where it originates. If you live in a cold climate and have a furnace or boiler in your basement, don’t forget about the carbon monoxide detector down there. It’s easy to miss an alarm if it’s sounding beneath your feet. The basement is also a good place to keep an eye out for high humidity, which can lead to mold growth and structural damage.


Quick tips for determining the amount of devices you'll need:


  • We recommend one nightlight per floor of your home.

  • However, if your alarms are interconnected, one nightlight will work for your entire home.

Quick tips for finding the best spot for your device: 

  • Locate your smoke and CO alarms, and then locate all of your available outlets. Pick an outlet that's between the two alarms. 

  • Avoid putting the nightlight behind furniture or any place that would cover it up.

  • Hallways and airy, central rooms are perfect locations.
