You should look out for supported protocols (i.e., Zigbee, Z-Wave, WiFi, LAN, etc.) while picking your smart hub. These are the protocols for communication between your smart devices and the smart hub. With that said, it’s worth mentioning that Zigbee and Z-Wave tend to be more reliable and responsive than WiFi when it comes to your smart home.
Smart hubs come from different vendors and in different flavours. Some smart hubs rely on the cloud, meaning you need to have an active internet connection to manage your smart home. This introduces some delay in your smart devices’ responsiveness. Also, some people have privacy concerns when it comes to their data on the cloud. Other smart hubs have both options; Local management & Cloud management, which in our opinion, is ideal.
You certainly don’t want to be stuck with a bulb that you don’t know how to pair with your Hub. Here comes the support’s role, although in our opinion, an active user community is way more important than traditional support. So, search to find out if the hub you’re after has a forum or an active blog.
One of the things you should carefully read before you buy a hub is the compatible devices list. A wide range of compatible devices will give you the freedom of choice. For example, you might want to install high-end smart lights, but budget on the smart plugs. A hub with a versatile compatibility list can certainly achieve that.
