Enabling the Dyson skill

Using the Alexa App on your mobile device or the Amazon website, search for "Dyson Skill". Once it appears, select the Dyson Skill and enable it.

You will be prompted to log in to your Dyson account. You should use the account you connected your machine with via the Dyson Link app.

Once you have logged in, follow the on-screen instructions to link Alexa to your Dyson machines.

How does Alexa identify my machine?

Alexa identifies Dyson machines using their room name. The room name is set when you first connect your machine with the Dyson Link app and can be changed using the Link app as well. A list of preset room names are available in the Dyson Link app, such as 'Bedroom' or 'Kitchen'.

For convenience, you can also rename your machine using the Alexa app. However, this does not affect the room name in the Dyson Link app or how you control your machine with voice commands.

To control a specific Dyson machine using voice commands, you can either directly name the machine in your first command or wait for Alexa to ask which machine you are referring to.

If you ask "Alexa, enable auto mode on Bedroom.", Alexa will identify the 'Bedroom' machine and enable the auto mode for it.

If you ask "Alexa, enable auto mode.", Alexa will ask which machine you want to enable the auto mode for.

Disabling the Dyson Skill

You can disconnect Alexa from your Dyson account and machines by disabling the Dyson skill. You can disable the Dyson Skill using the Alexa app or Amazon website.

Please note that you will need to log in to your Dyson account again if you choose to re-enable the skill.

Check if Alexa heard you

If Alexa did not respond to your most recent request, what you said may not have been recognised as a question or command. To make sure Alexa recognises your request, speak clearly and ensure you are close enough to your Echo device for her to hear you.

To check if Alexa is able to hear you, ask "Alexa, did you hear me?".

Check your Echo device

If Alexa is still not responding, please check the following:

• Make sure you are using the power adaptor that was included with your Echo device.
• Make sure you have an active internet connection.
• Ensure your Echo device isn't muted. The indicator light will be red when the device is muted.
• Move your Echo device to another location away from walls, speakers and other sources of background noise.
• Unplug your Echo device and plug it back in.

If Alexa is able to hear you, your Echo device should light up with a blue ring after saying "Alexa" to indicate she is listening. If your device has a screen, this will be shown as a blue bar on the display.

Reset your password

If you are unable to log in and link your Dyson account, you may need to reset your password. Select the forgotten password link on the log in screen to be taken through the reset process.

If the password has recently been changed, a 30 minutes period will need to pass before you are able to log back into the Dyson Link app account.

Multiple failures logging into the account (4 or more) will result in the account becoming locked. The account will remain locked for a 30 minute period.

Check for device or setup issues

In order for Alexa to discover your Dyson machine, it must be connected via the Dyson Link app and the Dyson Skill needs to be enabled.

If your machine has not been connected with the Dyson Link app, select the connection journey option to go through these steps.

Your Dyson machine and your Echo device should both be connected to the same Wi-Fi network to allow for discovery.

Check your machine

Turn off your Dyson machine at the wall for 10 seconds. Then turn it back on.

Do the same with your Echo device.

Check that your machine is online by viewing it in the Dyson Link app.

Check the Dyson skill

In the Alexa app on your mobile device, disable and then re-enable the Dyson Skill.

You will need to log into your Dyson account again after re-enabling the the Dyson Skill.

Ask Alexa what she heard

Alexa may have misheard you or misinterpreted something you said as a request. To understand why Alexa just did something, say "Alexa, why did you do that?" or "Alexa, what did you do?".

You can also ask Alexa to read back your most recent request by saying "Alexa, what's the last thing you heard?" or "Alexa, what did you hear?".

You can also view Alexa's activity in the Alexa app on your mobile device. The activity log shows utterances that Alexa heard, responses she gave and actions she took.

Alexa learns the more it is used and is always improving its natural voice recognition. Ease of use will improve over time, however some utterances and commands may need to be in a specific format for Alexa to recognise them.

For example, instead of asking "Alexa, turn on oscillation mode.", try asking "Alexa, turn on oscillation.".

This approach can work with other commands as well. Instead of "Alexa, turn on heating mode.", you can ask "Alexa, turn heat on.".

What are some of the things I can do with Alexa?

There are different kinds of directives that users can use to interact with Alexa. Here are some examples:

Turn settings on and off

• "Alexa, turn on my purifier."
• "Alexa, turn on night mode."
• "Alexa, turn off humidification."

Control number settings

• "Alexa, set the bedroom fan speed to 7."
• "Alexa, turn up the bedroom fan speed."
• "Alexa, decrease the bedroom fan speed by 3."

Changing mode settings

• "Alexa, set oscillation to wide."

Temperature controls (for Dyson heaters)

• "Alexa, make it warmer in here."
• "Alexa, make it cooler in here."
• "Alexa, turn off the heat."

How does Google Assistant discover my machine?

When you first connect your Dyson machine to the Dyson Link app you'll give it a room name. You'll find a list of pre-set room names in the app, such as 'Bedroom' or 'Kitchen'. Google Assistant uses this room name to identify your machine.

Google Assistant uses this to name your machine in the Google Home app as well.

How do I control an individual Dyson machine?

To control an individual Dyson machine using voice commands, you can either directly name the machine in your command or say the room name the machine is assigned to in the Google Home app.

If you say "Hey Google, enable auto mode in the Bedroom", Google Assistant will identify the machine named 'Bedroom' or a machine in the bedroom and enable auto mode.

Saying "Hey Google, enable auto mode", will enable auto mode for any purifiers in your current room, if the room is set up in the Google Home app.

Disconnecting your machine from the Google Home app

• It will be unlinked from your Google Account
• Data associated with this device will be deleted. Note: Some basic device data may remain associated with the home.

Check Google Assistant can hear you

Google Assistant may not have heard you or recognised your question or command. Make sure you are close enough to your smart home device and speak clearly.

Check Google Assistant can hear you by asking "Hey Google, what did I just say?". Your smart home device should light up when you say "Hey Google ...". If your device has a screen, you'll see it respond.

Check your smart home device

First, make sure:

1. Your Google Nest or Google Home speaker or display is powered on and plugged into a wall outlet
2. The microphone isn't muted
   • For Google Home: on the back of the device, touch the microphone mute button. Your Assistant will say whether the microphone is muted.
   • For Google Nest Mini (2nd gen) and Google Home Mini (1st gen): on the side of the device, toggle the mic switch. Your Assistant will say whether the microphone is muted.
   • For Google Nest Audio: on the back of the device, next to the power cord, toggle the mic switch. Your Assistant will say whether the microphone is muted.
   • For Google Nest displays: on the back of your display, use the switch to turn on the microphone. Your Assistant will say whether the microphone is muted.
3. The LED dots on top of your speaker or display spins or blinks when you say “Ok Google” or "Hey Google."
4. If your Assistant answers other questions, try to ask the unanswered question in a different way.

General troubleshooting

If you've checked off all of the steps above and your Assistant still doesn't provide an answer, try one of the steps below and ask your question again. If you still don't get an answer, move to the next step.

Reboot your speaker or display

1. Disconnect the power cable from your device.
2. Reconnect the power cable.

Make sure your device recognizes the hotword

Say “Hey Google” to your speaker or display. Check if the LED dots on the top of your device spin or blink, indicating that it recognized the hotword.

Make sure your device recognised the question correctly

1. Ask your Assistant the question again.
2. Say "Hey Google, repeat the question" to make sure your Assistant understood you correctly.
3. If it's still not recognizing the question, try to speak slower or try another question.

Resetting your password

If you aren't able to log in to link your Dyson account to the Google Home app, you may need to reset your Dyson account password.

Select the forgotten password link on the log in screen and follow the instructions.

After changing the password on your Dyson account, you'll need to wait 30 minutes before logging back in.

If you enter the password incorrectly more than four times, your account will be locked. It will be automatically unlocked after 30 minutes.

Siri will need to be enabled in your device’s Settings, to use Siri Shortcuts with the Dyson Link app.

Open Settings on your phone or tablet, then select ‘Siri & Search’. Next, to enable Siri, switch on ‘Press home for Siri’.

Before you can use Siri Shortcuts, you must first add your connected machine to the Dyson Link app.

To create a Siri Shortcut, tap the cog on the top right-hand corner of your home screen and select ‘Voice control’ and then ‘Siri’. Then select ‘Add new shortcut’. Next, choose the required settings and press the ‘Add to Siri’ button.

So that Siri can tell the Dyson Link app to run your shortcut, a personalised phrase will need to be recorded. We suggest that each phrase is unique and it’s recognisable.

For example, if you’ve selected Cooling mode and Night mode, this could be named “Bed time” or a heating specific setting could be named “I’m cold”.

Please note, generic phrases already programmed into Siri can’t be used. An example of this is “Good Morning”.

A list of all personalised phrases will be stored on the ‘Your Siri Shortcuts’ screen for each machine.

To view this, simply tap the cog on the top right-hand corner of the relevant machine’s home screen and select ‘Voice control’ and then ‘Siri’.

Next, select the relevant Siri Shortcut. From here, you can re-record the phrase or deleted the shortcut.

With Siri Shortcuts, you can control your air treatment machine(s) using your voice. You can create, edit and delete your own personalised commands, which can be activated through your mobile or tablet.

Each Siri Shortcut is unique to the machine it was created on and cannot be applied across multiple machines.

You’ll need to create different Siri Shortcuts for each machine and a new personalised phrase will need to be recorded.

Should a personalised phrase be recorded across multiple machines, Siri will display these on your device as selectable options, along with a machine identifier.

If you have multiple machines using the Siri Shortcut feature, we recommend making each phrase unique. For example, if one machine is located in the kitchen and another is in the bedroom, include these locations in the phrase.

Siri Shortcuts can be used in any region where Apple supports Siri. To see if this is supported in your region, please visit the Apple website.

You can activate Siri Shortcuts on the Dyson Link app in one of two ways:

1. Simply say, “Hey Siri”, followed by the pre-recorded personalised phrase.*
2. By pressing your mobile or tablet’s ‘Home’ button to activate Siri, and then saying the pre-recorded personalised phrase when prompted.

Either way, you’ll need to be logged into the Dyson Link app.

*This option will needs Siri to be enabled in your phone or tablet’s Siri settings.

Siri Shortcuts is available on iOS 12 or later.

Plug the machine back in and retest.

Please ensure you have the most up to date software downloaded before beginning any checks. We strongly recommended enabling auto-updates in your Dyson Link app settings, to allow the most up to date software to be installed as soon as it is available.

The colour of the numbers and readings on the display are linked to the air quality of the respective category.

Green denotes a high air quality, with low pollutants, and red, low air quality with a high amount of pollutants.

Different categories can have different levels of pollutants at the same time, and will therefore display in different colours.

The interface is designed to stay on the screen you select. Please ensure the remote is not being accidentally pressed.

There may be times when the display is showing green but the fan speed is still high.

This is due to the machine always trying to maintain high air quality. For example, in a room with leaky windows, the machine has to work harder via a higher Fan speed to maintain a high air quality.

If you want the fan to be quieter, you can choose to change the airflow direction to face backwards, or turn the machine to manual mode and lower the airspeed.

Fault

Reset the machine.

Unplug the machine and leave it for 10 seconds.

Plug the machine back in and retest.

Night mode is not working

When in Night mode, your machine will automatically sense the ambient light level and adjust the resting screen brightness accordingly.

If the room is bright, (for example, the lights are on), the screen's display will be set to minimum brightness. If the room is dark (lights off) the screen is turned off.

In both scenarios, when the machine is interacted with, the screen brightness will uplift.

If your screen is not displaying correctly (incorrect reading, white screen etc), please ensure you have updated all the software to the latest version.

When setting up a product, we strongly recommend enabling auto-updates, to allow your machine to easily download the latest software.

To enable auto-updates, open the Dyson Link app and click the cog at the top right of the home screen.

Click 'Your Purifier's settings'.

Scroll down to 'Software' and enable Auto-update.

Restart the machine

Switch off and unplug the machine.

Ensure all outside doors and windows are closed.

Vacuum the two sensor slots to the left of the LCD screen with a Dyson brush attachment.

Plug in and test the machine.

Switch off and unplug the machine.

Move the machine to another room.

Plug in and test the machine.

The first time your purifier is turned on, the gas sensors will perform a self-calibration which takes one hour after which time they will work normally.

If the power cuts out within the hour, the initialisation period will continue from where it left off.

If your machine is new out the box and has not been turned on for over an hour, please allow a full hour to complete, with your purifier plugged into a secure power source.

Once the full hour has elapsed, turn the machine off and then on again, either with the main power button on the machine, or the remote control.

If your purifier has been plugged into a stable power source for over one hour, and the VOC and/or NO2 screens still do not show, please unplug your machine from the wall, leave for one minute, plug back in, and then turn on using either the main power button, or the button on the remote.
