Maybe you love displaying giant inflatable ghosts, strings of spooky lights, fog machines, or strobe lights at this time of year. But programming light timers to turn everything on and off each night? Not so much.
A smart plug can help. Plug one into an outlet, plug your lights into it, and program them from your smartphone so that they turn on at dusk and switch off at midnight—or dawn, if you want to keep the Halloween fun going all night long.
We’ve tested 15 smart plugs, including both indoor and outdoor models. The outdoor models in particular are very handy for Halloween light displays. Prices start at just $8 for indoor models and $18 for outdoor models, with options available from Amazon, GE Lighting, Leviton, TP-Link, Wemo, Wyze, and other brands.

How Connected Devices Can Make Life Easier Around the House
A smart plug is more convenient than manual light timers because many smart plugs can automatically turn things on or off at sunset and sunrise—and adjust those times based on where you live. For example, at CR’s headquarters in Yonkers, N.Y., the sun sets 73 minutes later at the beginning of November than on Dec. 31. A smart plug can shift those times on its own. Now, manual timers with light sensors can also turn on at dusk and off at dawn, but they require an outlet with plenty of sun exposure, and no nearby light fixtures to confuse them.
Some smart plugs can also use your phone’s location to turn lights off and on when you leave and return home. This feature is useful for making sure you don’t come home to a dark house, or to simply keep your ghosts and goblins off when no one’s home and save some energy. Finally, some smart plugs also offer energy-monitoring features, allowing you to see just how much electricity that inflatable witch is really costing you.
How to Use a Smart Plug as an Outdoor Light Timer
Here’s how to set up your smart plug as an outdoor light timer in three simple steps. Once you’ve set it up, you can keep the plug handy for your other outdoor holiday decorations. You can also use it anytime for controlling household items like fans, lamps, and heaters. (For more ideas on how to use smart devices to make your home more convenient, efficient, and fun, see our smart home toolkit.)
Step 1: Pick a Plug
If you’re using an indoor outlet in, say, a garage, any smart plug will do. Outdoor outlets require an outdoor smart plug. These tend to cost a bit more than indoor models and are becoming more widely available in stores. And if you need an extension cord, make sure it’s rated for outdoor use.
If you need to power a particularly elaborate light display, consider a multi-outlet outdoor smart plug with a yard stake. These plugs typically have three to six outlets and a 6-foot power cord. They aren’t as widely available, though, and are made only by a few lesser-known brands, such as Enbrighten, Feit Electric, and WiOn.
Whichever smart plug you get, make sure it has sunrise and sunset automation and uses WiFi. Models from Amazon, Feit Electric, GE Cync, Leviton, Meross, TP-Link, and Wemo have both. If you buy a plug that doesn’t use WiFi, you may have to buy an additional hub to connect it to the internet. For example, Lutron smart plugs require an $80 bridge, while Ring smart plugs require a $50 bridge. (Ring company offers the plug and bridge in a $50 bundle to get you started.)
If you buy a plug that lacks sunrise and sunset automation, your only other option is to connect it to a compatible smart home control app (Amazon Alexa, Apple Home/Siri, Google Home/Assistant, or Samsung SmartThings) and use the app’s sunrise/sunset automations.
Based on our lab tests of 15 smart plugs, we recommend going with the GE Cync Indoor Smart Plug CPLGSTDBL, $15, for indoors and the Amazon Basics Outdoor Smart Plug HPPA52CWBAMZ, $24, for outdoors. If you want to buy both indoor and outdoor smart plugs from the same brand, you could also consider the GE Cync Outdoor Smart Plug CPLGOD2BLG1, $30, so that you can control all of your plugs from the same app. For more options, see our review of the best smart plugs.

Step 2: Set Up the Smart Plug
Insert the smart plug into the outlet you want to use, download its smartphone app, and set up your account. Add the plug to your account and enter your WiFi credentials so that the plug can join your WiFi network.
The app may ask for your address or access to your smartphone’s location, which you’ll need to provide in order for the plug to look up your local sunrise and sunset times. If your plug offers two-factor authentication, be sure to enable it for added security against hackers. (For more digital security tips, see our guide to locking down smart home devices.)
Step 3: Program the Plug
Look for the Rules or Scheduling settings in the app. (It may also be called Routines, Automations, or something similar.) You can choose sunset as the time for the plug to turn on, if you want holiday decorations to come on when it gets dark. Next, set the plug to turn off at midnight, sunrise, or another time of your choosing.
Then sit back and bask in the glow of some low-maintenance Halloween fun!
