Track indoor climate conditions to help prevent mold, moisture damage, or discomfort — even in hard-to-reach places.

On Amazon Sidewalk, these devices stay connected for reliable protection day and night.1 Add more devices anytime to expand your coverage as your home security needs grow.

Protect your home from burst pipes with this SimpliSafe Temperature Sensor. It sounds an alarm if the temperature drops below 41 degrees F, and with a monitoring plan, you can receive a phone call, text or email notification of a potential freeze. Place this SimpliSafe Temperature sensor in any climate-controlled room to protect fine art and other temperature-sensitive items.

The First Alert® SMCO100 Battery-Operated 2-in1 Combination Smoke and Carbon Monoxide Alarm provides protection against both threats in a single alarm. Installation of the battery-operated detector is simple - no wiring is required. Add fire and CO protection throughout your home in minutes and help prevent unwanted removal of the battery or alarm using the optional locking features. Easily test the battery-operated combination detector using the single test/silence button to help ensure it is operating properly and silence false alarms. A low-battery warning will tell you when to replace the alarm battery. Detectors themselves should be replaced at least every 10 years. The end-of-life warning will help notify you when it's time to replace. See user's manual for information on how and when to test and replace detectors.
