Installing and setting-up Alexa

To get started with Amazon Echo, place the device in a central location (at least eight inches, or 20cm, from any walls and windows). Plug the power adapter into Amazon Echo and then into a power outlet. The light ring on Amazon Echo turns blue and then orange. When the light turns orange, Amazon Echo greets you.

Next, you'll need to downlaod the Alexa app. Go to the app store on your mobile device and search for 'Alexa app'. Then select and download the app. Launch the Alexa app and ensure the account details are filled out. In the Alexa app, open the top left menu. Select 'Settings', then 'Set up a new device'. On the top of your Echo, press and hold the 'Action' button for five seconds. The light ring turns orange and Echo will connect to your mobile device.

Back on the Alexa app, select home Wi-Fi network and enter your home Wi-Fi password. Select 'Connect'. A confirmation message will appear in the app.

Tip: If your Amazon Echo doesn't connect to your Wi-Fi network, unplug and then plug the device into a power outlet to restart it. If you still have trouble, reset your Amazon Echo to its factory settings and set it up again.

Try talking to Alexa. You'll find that you can now use your Amazon Echo device. To get started, say the 'wake word' (Alexa) and then speak naturally to Alexa. Once you've set-up the Dyson skill, remember to use the trigger word (Dyson), preempted by the command 'ask/tell'. For example, "Alexa, ask Dyson purifier to turn on".

Your Amazon Echo device is set to respond to the wake word "Alexa" by default, but you can use the Alexa app to change the wake word at any time. In the app, go to 'Settings', select your Amazon Echo device and then select 'Wake Word'.

Connecting for different product combinations:

If you have the Dyson Link app and Alexa app both installed, and your Dyson machine and Amazon Echo are both connected, but your Dyson skill is not enabled:

Ask Alexa to enable the Dyson skill, or search for Dyson in the skills section of the Alexa app. Then select the 'Enable skill' button. Allow the Alexa skill to access your Dyson Link app account. Enter your Dyson Link app account details and select 'Allow' on the confirmation screen.

If you have the Dyson Link app installed, your Dyson machine is connected but the Alexa app is not installed and your Amazon Echo is not connected:

First, check the Wi-Fi signal strength where your Amazon Echo is positioned, by using a device known to be working. Remember to place your Amazon Echo at least eight inches away from any walls or windows, in a central location. Ensure the power adapter is plugged in and switched on.

The light ring on the Amazon Echo will turn blue then orange. When the light turns orange, Alexa greets you. Next, download the Alexa app to set-up your Amazon Echo.

In the Alexa app, open the main menu and select 'Settings' and then 'Set up a new device'. Press and hold the 'Action' button on your Amazon Echo for five seconds. The light ring will turn orange and Echo will connect to your mobile device.

Next, select your Wi-Fi network and enter your Wi-Fi password. Then press 'Connect'. A confirmation message will display in the app.

Wi-Fi connection issues

It is important to ascertain if the issue is with Alexa/Echo, or with the Dyson product. Try asking Alexa a general question, such as 'Alexa, what is the weather for tomorrow?'

Operate your Dyson product manually-use the remote or controls to turn the purifier on, or press the power button on the robot.

Echo’s connectivity status is indicated by the power LED on the bottom rear of the device, with white meaning good and orange denoting no Wi-Fi connectivity. If you’re experiencing intermittent connectivity or non-existent Wi-Fi connectivity with your Amazon Echo, here's what to try.

First, reboot your router and turn your Echo off and on again, waiting at least 10 minutes to give time for them to reconnect. Whilst waiting, you can also try re-positioning your Echo away from devices that may be interfering with the signal.

You can also reduce the congestion on your Wi-Fi network by removing unused devices from the network.
If you have a dual-band modem, you may effectively have two networks set up. Try switching the device from the 2.4GHz frequency to the 5GHz frequency or vice-versa.

5GHz promises less interference, better speeds and a more stable connection and it is often less congested.

Alternatively, 2.4GHz can better for devices that may be further away from the router, especially if the signal has to pass through walls.

Move your Echo to higher ground, like a bookshelf, to avoid signal interference.

Controlling multiple machines

If you have more than one Alexa-controlled Dyson machine, your voice commands should make it clear which one you want to control. You can include a word like 'purifier', 'fan' or 'robot' in your command so Alexa knows which one you mean.

If you have two or more similar machines, like a purifier in your kitchen and another in your bedroom, you can assign location labels to differentiate your machines.

Navigate to your machine's settings by selecting the cog icon on your machine's status screen. From here, select 'Your machine's settings'. If you're using a purifier, select 'Room name' and choose the appropriate location. If you're using a robot, choose 'Robot name' and select a room from the predefined list.

Enable/Disable Dyson skill

If you own an Amazon Alexa-enabled device, you can control and monitor your Dyson connected machines using your voice. Simply enable the Dyson skill to do this.

To enable the Dyson skill, begin by saying the following: "Alexa, enable the Dyson skill." Alexa will respond: "OK, I've enabled the Dyson skill for you, but it requires you to link your Dyson account." Next, in the Alexa app, search for Dyson skill. Then select 'Enable' and follow the on-screen instructions to link your accounts.

To disable the Dyson skill, search for Dyson skill in the Alexa app and choose 'Disable skill'.

Continuous monitoring

The continuous monitoring option is used for air quality, temperature and humidity data to be relayed to the machine and app at all times, even when you have turned the purifier off. The sensors have small fans that maintain airflow for continuous monitoring, but this should not cause any audible noise interference.

There may be instances when the display shows green, indicating high air quality, but the fan speed is still high. This is due to the machine constantly seeking to maintain a good air quality, and in scenarios such as rooms with leaky windows, the machine must work harder to maintain a good air quality.

This will only happen when the machine is set on auto. To turn off auto mode, please select manual mode, either using the remote control or on the app.

Please check the following on the app:

Swipe up to reveal the setting tab and tap to open options.

Swipe down to find the continuous monitoring option and tap to open.

Turn off the 'collect data when in standby' option. (The icon will turn grey when turned off). Save the change by pressing 'Done' at the top right of the page.

Continuous monitoring can now also be turned on/off by pressing the the 'Auto' button on the remote control for five seconds.

Please ensure you have the most up to date software downloaded before begining 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 avaliable.

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.

My display is reading green but the fan is working at high speed

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.

My readings are showing in different colours

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 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 initialization period will continue from where it left off.

How long has your purifier been turned on for?

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.

Do the VOC and/or NO2 readings now show?
