Smart home hub
A smart home hub,[1] sometimes referred to as a "smart hub", "gateway'",[2] "bridge", "controller" or "coordinator", is a control center for a smart home, and enables the components of a smart home to communicate and respond to each other via communication through a central point.[3] The smart home hub can consist of dedicated hardware and/or software, and makes it possible to gather configuration, automation and monitoring of a smart house. A smart home can contain one, several, or even no smart home hubs. When using several smart home hubs it is sometimes possible to connect them to each other. Some smart home hubs support a wider selection of components, while others are more specialized for controlling products within certain product groups or using certain wireless technologies (e.g. Z-Wave).
A smart speaker with a virtual assistant can often be used for speech input to a smart home hub.
Open or closed source code
Smart home hubs can have software with open source code or use proprietary software with close source code, and independently of this the application programming interface can be public or closed. Some smart home hubs must run on proprietary hardware, while others (like for example Home Assistant) can be installed on generic hardware (like for example a laptop or single-board computer with Linux).
Examples of commercial smart home hubs
Some examples of smart home hubs with closed source code are:
- Logitech Harmony Hub[4]
- SmartThings Hub[5]
- Google Nest Hub[6][7]
- Apple HomePod
Some examples of smart home hubs with free and open-source software are:
Some examples of smart home hubs with closed source code, but an open application programming interface are:
Communication protocols
Various communication protocols can be used between smart home hubs and smart house components.[8] The protocols can be grouped into wired and wireless technologies.
Wireless protocols
Some examples of wireless protocols commonly used in smart home hubs are:
- RF 433 (433 Mhz, various protocols)
- 2,45 Ghz (WiFi, Bluetooth, Zigbee)
- RF 868 (868 Mhz, various protocols)
- Z-Wave (868 Mhz)
- Infrarødt lys (430 THz; 697 nm)
Wired protocols
Some examples of wired protocols commonly used in smart home hubs are:
- Bus systems
- DMX512
- KNX
- LONworks
- X10 (widespread in older home automation equipment in the USA)
- Automation solutions built directly into electric panels
