Meet Samsung's second-generation SmartThings Hub and sensors.
The standalone hub will set you back $99 (£100 in the UK).
And the individual sensors are available a la carte on the SmartThings site, although the brand plans to integrate bundled kits in the future.
Download the SmartThings app on your Android, iOS or Windows device to get started.
The new hub looks a lot like the old one.
It comes with a power adapter and an Ethernet cable and connects directly to your Wi-Fi router.
We tested out an assortment of SmartThings-brand sensors, as well as some third-party integrations.
This $30 (£30) Arrival sensor issues an alert when you come and go.
SmartThings' $40 (£30) Multipurpose sensor keeps track of a single door, window or cabinet, letting you know when it's opened or closed.
Stick the $40 (£30) Motion sensor anywhere you'd like to track movement -- and receive activity-based alerts.
