Update: For a limited time, you can grab the SmartThings Hub from Amazon for just $49.99.

SmartThings has a Lighting Kit on sale for $99. Once you add it to your cart, the site should discount $40 automatically. Shipping is free to anywhere in the U.S. It's a good deal because the lighting kit includes the Samsung SmartThings Hub, Motion Sensor and two Sylvania Lightify smart light bulbs. The Hub itself is $99 usually, so you're essentially getting the $36 Motion Sensor and $12 worth of light bulbs for free.

Hubs like this act as the "brain" of any smart home. As you start adding more smart features, like a thermostat or smart plugs, you want to be able to control all of them at once. The hub lets you connect everything to it and then control them from one single place. With this lighting kit, you can connect the motion sensor and the bulbs to the hub and use it to schedule the lights coming on or off, lighting when the motion sesnor activates, or any other number of things you can think of. The SmartThings Hub works with Wi-Fi networks, Bluetooth, and other wireless protocols like ZigBee.

The biggest negative against it is that the companion app is crazy complicated, which means it might be hard to get started with it but once you do you'll be able to do all sorts of things.

The Samsung SmartThings Hub is one of the best reviewed smart hubs out there. Tom's Guide called it the Best Smart Home Hub in 2017. PC Mag named it their Editor's Choice, gave it 4.5 stars out of 5, and called it "one of the most versatile home automation hubs around."

Add an extra bulb or motion sensor if you need to cover more rooms. You could also look at adding the SmartThings home monitoring kit for extra control over your smart home. It has been on sale a few times recently, so keep an eye open.

If you want to invest in a smart home hub but don't need all the accessories, you could always start with an Amazon Echo Dot. It can work as a hub for a lot cheaper, especially with Alexa-enabled smart devices.
