There’s nothing more comforting for a parent than knowing that your family and home are safe and secure. Here are three cool smart home devices that offer peace of mind.

iHome iSB02 Wi-Fi Dual Leak Sensor

Water leaks can destroy a home. iHome offers a cool, affordable device that can detect a leak before it gets bad. The iHome iSB02 has two sensors that are placed to cover an area near a sump pump, hot water heater, or under a sink. If it detects water under the sensor, it sends an alert to your smartphone. The device runs on batteries and it uses Wi-Fi, so you don’t even need a smart home hub. $25

Google Nest Hub Max

The new Google Nest Hub Max is an awesome smart home hub with a giant 10-inch screen, a great speaker, and a built-in camera. It does everything you expect a Google smart home device to do, including video calls, music, and video streaming. What’s cool is that the camera also doubles as a Nest home security camera. Place the Hub Max in your kitchen or living room to keep an eye on your home while you’re away. A standard Nest camera costs about $200, but for just $30 more the Hub Max includes so much more functionality. $230

Airthings Wave Smart Radon Detector

Odorless radon is a danger in Colorado and many of us have high levels in our homes and don’t even know it. This is especially concerning in finished basements that are often play spaces for kids. The Airthings Wave Smart Radon Detector constantly monitors radon along with temperature and humidity and tracks those levels in the Airthings app. It looks like a smoke detector, attaches to the ceiling or wall, and works on batteries and bluetooth so no wiring is needed. You can use the app or do a quick check for radon levels by waving your hand in front of the unit. It’s a great way to keep constant tabs on radon in your home. $200
