hubThere are many different types of smart home hubs available. But what do they do? and do you need them?

Some of these hubs are required by the networking technology you are using or planning to use..e.g Zwave, Zigbee.- See home automation protocols and devices.

Other Hubs are add-ons and are used for making home automation easier.

Others connect networks of different type together e.g Zwave to TCP/IP.

Some Smart Hubs e.g. Samsung Smarthings do all of these .

Smart Hub Features

The main feature you need to look out for are:

  • Voice control
  • Work with Alexa, Google Home or Apple
  • Multiple protocol support-Wi-Fi, Zwave, Zigbee,Wi-Fi etc
  • Control via IOS, Android and Windows
  • Ability to use IFTTT rules (If This Then That)
  • MQTT support
  • IP support for connecting the cloud.
  • Security.

Important Things to Consider

  • Are my current devices e.g. locks,lights etc supported by the hub?

Common Questions and Answers

Q- Do I Need A Hub?

A- Whether or not you need a hub will depend on the networking technology that you are using or planning to use. Generally if you are using Z-Wave or Zigbee then you will need a hub.

Q- What is the difference between a hub and a gateway?

A- In networking terms a hub connects the devices of the same type together. For example a Wi-Fi hub connects wi-Fi devices together. Whereas a Gateway connects devices of different types together. For example you need a gateway to connect a wi-Fi network to a Z-wave network. However the terms are used very loosely and you often find hubs ( e.g Samsung smartthings hub) are hubs and gateways.
