Keyless/remote entry door locks

Have you ever left the house and worried that you left the front door unlocked? If your home is equipped with a keyless/remote entry door lock — available from multiple manufacturers — you can use an app on your smartphone to lock the door from wherever you are. Some manufacturers make versions that will also send a text or email to your phone when the door opens. Locks that can be programmed with multiple entry codes also allow you to see who comes and goes and when.

Smart lighting

From lighting automation that allows you to control lights remotely and wirelessly, to energy-efficient LED bulbs that can change color to match your mood and decor, lighting has come a long way. Some smart lights work in tandem with home automation systems to allow you to turn them on or off, or even dim them, from an app on a smartphone or tablet. Others require no communication hub and can be controlled directly from your mobile device. You can also put some smart bulbs on timers (using your wireless device), sync them with certain TV shows or movies, and integrate them with security cameras and thermostats.

DIY security systems

Don't want to sign a contract or deal with complex security systems? Install-it-yourself security systems are affordable and offer security features like cameras, sensors, motion detectors and alarms or sirens, without the need for a security service to monitor them.

Smart appliances

The Internet of Things (IoT) — everyday objects that have network connectivity — includes a growing list of smart appliances. Many manufacturers are offering washers, dryers, refrigerators and other home appliances that can communicate with you — and each other — wirelessly. Many can be controlled remotely from your smartphone — so if you leave the house and can't remember if you turned off the stove, you can check in and turn it off using your smartphone app.

While appliances aren't always included in a home sale, they do make for interesting features that keep your home top of mind to buyers.

Smart plugs

One of the easiest, most affordable smart home upgrades you can make is to add smart plugs to your home. These Wi-Fi-enabled plugs fit existing outlets and can be controlled from a smartphone app. Plug anything into a smart plug, like lights or a television, and you can turn it on or off remotely, track energy consumption, or even create an on-off schedule.

Temperature controls

Programmable thermostats were just the beginning; today's home temperature controls are even smarter. Like other smart home features, smart thermostats can be controlled remotely from your mobile device. You can program them to make automatic temperature adjustments and then use your smartphone to override the program like turning up the heat on a particularly cold day. Some smart thermostats learn from household behavior and adjust the temperature to meet your family's needs and save energy, while others adjust based on the number of people in a room. And several can now be operated via voice-controlled virtual assistants.
