From A-Z


Also called Actions on Google. Custom interactions built into the Google Nest speakers with voice assistant by third party partners like HeadSpace or TrainLine. Say "Hey Google, add bananas to my shopping list", "Hey Google, turn off the TV", or "Hey Google, tell me a joke".

Alexa Skills are the equivalent for Amazon Echo.


Short for applications. Apps are software programmes you use on your smartphone, tablet or computer.


Or home automation. A feature of smart homes. It describes the capability to automate tasks, or a series of tasks, you used to do manually. Like turning off the lights, locking the front door and turning down the heating when you go to bed.

These automated routines are carried out by smart devices which are programmed or triggered by sensors or by other devices.


Connects a group of devices that share a common protocol to a single smart home controller.

An example is the Phillips Hue Bridge. Hue lights communicate with each other using the Zigbee protocol. The bridge connects up to 50 Philips Hue lights and links them with Google Nest speakers with voice assistant, Amazon Echo or, Apple HomeKit, integrating their control with the smart home system. Giving you smart lighting at a touch of a button.

The Cloud

Computing services delivered over the internet, not installed or stored on your device. These services include software and data storage.

Google Drive, Microsoft OneDrive, Apple iCloud and Dropbox are cloud services.

Smart home devices often use cloud services, so you can access them anywhere and data is backed up securely.

Connected devices

Another term for smart devices. Gadgets that are connected to and controlled via the internet.


A device which controls your smart home. Controllers include smart speakers, smart displays and hubs. You can have more than one controller. For example, you can have mini smart speakers in different rooms so your voice assistant can hear you all over the home.

A smart device can be almost any electronic device in the home. Plugs, security cameras, lighting – anything that can be connected to and controlled via the internet.

Also referred to as a smart product or connected device.

Ethernet port and cables

Connections for wired internet devices. Before Wi-Fi all devices used these! There are usually ethernet ports on the back of a router. You may need them for connecting a bridge or a hub.


A digital boundary you can set to trigger your smart devices. It could be around your home or workplace. For example, when your phone is detected (using geolocation) within your home geofence, you can pre-programme your outside lights to automatically switch on.


A feature of smartphones that shares your location with other services. It's how Google Maps knows where you are. You can use geolocation to trigger smart home devices or routines. This usually works with a geofence.


A central controller for all your smart home devices. A hub may be a dedicated device or integrated into a smart speaker or display.

IFTTT (If This, Then That)

IFTTT is a protocol that connects different apps and devices so they can do things they couldn't do on their own. It's a way of creating customised automation.

IoT (Internet of Things)

A collective term referring to smart devices that connect to the internet and each other.

Mesh network

A type of wireless network that gives whole-home coverage, supports higher network speeds and improves network strength and reliability. All ideal features for a smart home!

Instead of using a single device, like a router, at its centre, a mesh network uses multiple devices to create blanket network coverage. Not relying on a single central device makes mesh networks faster as well as stronger. Google home Wi-Fi connects through this system.

Z-Wave and ZigBee enabled smart devices use mesh networking, and mesh Wi-Fi setups are now widely available.

MU-MIMO (Multiple user, multiple input, multiple output)

The next generation of Wi-Fi, called Wi-Fi 6, will be faster in lots of ways. MU-MIMO is one of those ways. It allows multiple devices to connect to Wi-Fi at the same time.


The process of adding a device to your network. After pairing, your devices stay connected.

Protocol (internet protocol)

A language or set of rules used by devices to communicate with other devices. Bluetooth and Wi-Fi are examples of protocols. ZigBee and Z-Wave are protocols developed for smart home technology.


The box that connects devices to create your Wi-Fi network. Most home routers also contain a modem, which connects your home network to the internet.


A series of tasks carried out by smart home devices, routines are what home automation is all about.

You can create your own routines, for example, your bedtime routine might be turning off the lights, locking the front door and turning down the heating when you go to bed.

Your routine can then be triggered with a wake word, for example, "Hey Google. Goodnight" or "Alexa, it's bedtime".


Devices that detect change — movement, temperature, noise or light. Smart sensors trigger actions and devices. For example, a smart motion sensor could trigger a smart security camera and an alert to be sent to your phone.


Or Alexa Skills. Custom voice commands that ask Amazon Echo with Alexa, Amazon's voice assistant, to perform tasks. Say "Alexa, dim the lights", "Alexa, find my phone", or "Alexa, call me a taxi".

Google Actions are the equivalent for Google Nest speakers with voice assistant.


Describes a device that can connect to the internet and be controlled remotely by smartphone, tablet or computer. For example, smart speakers, smart lighting and smart cameras.

Smart displays

A voice assistant and smart speaker with a display, and usually a touch screen interface. These can act as a hub – a central controller for all your smart home devices, with the added advantage that you can view and tap as well as use voice control.

Smart home

A home with smart devices that can be connected to the internet and controlled by smartphone, tablet or computer.

Smart meter

A device installed by an energy supplier to send meter readings automatically. They're clever, but don't integrate with your smart home devices.

Smart plugs

A socket adapter that connects normal plug sockets with your smart home network. Paired with an app or smart speakers, smart plugs give you remote control over almost anything plugged-in.

Forgotten to unplug the TV? Turn it off remotely. Programme lamps and radios to give the impression you're home when you're not. Easily control hard to reach sockets. Smart plugs are incredibly useful and simple to install.

Smart speakers

These are often the central part of your smart home set-up and can help with daily tasks and controlling your smart home. They include a voice assistant, so you can control your smart home just by speaking to the smart speaker. They're also great for playing audio and having more than one gives you the possibility of a multi-room audio setup.


A way to watch or listen online without downloading a file. Services like Netflix, BBC iPlayer or Spotify are streaming services.

Voice assistant

Voice activated software that lets you control devices by talking to them. Voice assistants live on devices like smart speakers and displays, as well as on smart phones. Try Google Nest speakers with Home Assistant and Amazon Echo with Alexa.

Voice assistants are also sometimes known as virtual assistants, digital assistants, AI assistants, intelligent virtual assistants, voice user interfaces or voice control.

Wake word

A word or phrase that prompts your voice assistant to listen to your instructions. Some well-known wake words are:

Google Home: ‘Hey Google...’ or ‘OK Google...’ Amazon Echo: ‘Alexa...’ Apple: ‘Hey Siri...’


Wireless internet. At home, you usually have a router which wirelessly connects your devices to the internet.

Smart home don't necessarily need internet access. But some devices won't work without it, and those that do will have their capabilities limited. You would also miss out on features like remote access, for example checking your smart cameras.

Wi-Fi boosters and extenders

Argh! The dreaded dead zone. That spot where your Wi-Fi just won't reach. One solution is to add Wi-Fi boosters around the home, which rebroadcast your router's signal to reach those far flung corners.

An alternative solution is a mesh network, a system which creates dead zone free Wi-Fi coverage. It's a neat alternative to adding ad-hoc boosters, although more expensive (at the moment).

Wireless network

A group of electronic devices wirelessly connected to each other and the internet.

Works with

There's so many devices and technologies, it can be hard to know what works with what. To make choosing easier, we’ve organised our smart range so you always know what works with what.

And don’t forget, even if a device you're interested in doesn't work directly with your smart speaker, you could still control it separately using an app on your smartphone.

ZigBee and Z-Wave

Protocols used to create wireless networks of smart devices. Designed specifically for smart homes, these protocols suit the low power, low data needs of smart home devices. Wi-Fi, by comparison, is geared to bigger data and consumes more power.

Phillips Hue smart lighting uses Zigbee to communicate. To add a series of Hue lights to a smart home setup that isn't Zigbee compatible, you would need to use a bridge. Both ZigBee and Z-Wave are mesh networks.
