have an account, tap Log In. To create a  
new account, tap Sign Up.  
Figure 3.1  
Note:  
The humidifier will not mist in Auto Mode if the  
humidity level is above 50%. If you want the  
humidifier to keep misting, change the mist  
setting, or change the Auto Mode settings in  
the VeSync app.  
Note: You must create your own VeSync account  
to use third-party services and products. These  
will not work with a guest account. With a VeSync  
account, you can also allow your family and  
friends to control your smart humidifier.  
For more information about Auto Mode, see  
3. Follow the in-app instructions to set up  
your smart humidifier.  
3. Rotate the nozzle to adjust the direction  
of the mist. [Figure 3.2]  
Note: You can use the VeSync app to connect  
your smart humidifier to Amazon Alexa or Google  
Assistant™. Follow the in-app instructions to  
connect VeSync to your voice assistant.  
4. Optionally, use the controls to activate  
Sleep Mode, turn the night light on/off,  
and more (see Controls, page 6).  
5. When your room has reached your  
preferred humidity level, turn the  
humidifier to a lower setting, or turn it  
off. A healthy humidity level is between  
40% and 50%. [Figure 3.3]  
Figure 3.2  
Note: You can also use Auto Mode to keep the  
humidity level between 40% and 50%.  
6. Press  
to turn your humidifier off.  
Note: If there is no water in the tank or the tank is  
removed, the humidifier will stop misting, will  
flash 10 times, and the humidifier will turn off. Refill  
the tank and properly place it on the base to use  
your humidifier.

Sleep Mode  
VeSync App Functions  
Important Tips  
Sleep Mode changes the humidifier’s mist  
setting to Auto Mode, turns off the display  
lights, and turns off the night light.  
The VeSync app allows you to access  
additional smart functions, including those  
listed below.  
Your humidifier must have the correct level of  
water in the base chamber to work properly. If  
there is too much water in the base chamber,  
the humidifier cannot create mist.  
When Sleep Mode is on, you can press  
to turn the night light on/off. The  
humidifier will stay in Sleep Mode.  
Remote Control  
Never pour water directly into the  
base chamber. [Figure 3.4] Only add  
water to the water tank. The humidifier  
will automatically release the correct  
amount of water into the base chamber.  
Turn the humidifier on/off from your phone.  
Cycle through mist levels and turn on/off  
Auto Mode and Sleep Mode from your  
phone.  
Auto Mode  
Figure 3.4  
Turn the display lights and night light  
on/off from your phone.  
Customise Auto Mode settings like target  
humidity and auto-off.  
Avoid moving or shaking the humidifier.  
[Figure 3.5] This may cause the water  
tank to release too much water into the  
base chamber.  
Auto Mode uses the humidifier’s sensor to  
automatically adjust the mist level (or turn it  
off) to maintain a comfortable and healthy  
level of humidity.  
Monitor Humidity Levels  
Before moving the humidifier, turn it off,  
unplug it, and remove the water tank.  
Auto Mode automatically adjusts the  
mist level to maintain 40–50% relative  
humidity. You can change the target  
humidity level in the VeSync app.  
Check current humidity levels in the  
humidifier’s environment.  
If your humidifier doesn’t produce mist  
correctly, check the max water line to  
see if there is too much water in the  
base chamber. Pour out extra water if  
water is over the max line. [Figure 3.6]  
Set Timers & Schedules  
By default, Auto Mode uses Automatic  
Stop. The humidifier will stop misting  
when the highest target humidity level is  
reached. If the humidity drops below the  
target humidity level, the humidifier will  
begin misting again.  
Program individual timers or create a  
schedule for your smart humidifier.  
Note: The max water line is only for this purpose.  
Do not pour water into the base chamber.  
Third-Party Voice Control  
Compatible with Amazon Alexa and  
Google Assistant for voice commands.  
Figure 3.5  
If Auto Mode is selected when the  
humidity is higher than the target  
humidity range, the humidifier will not  
start misting until the humidity lowers.  
Note: The VeSync app is continually updated and  
app features will expand.  
In the VeSync app, you can turn  
Automatic Stop on/off. If Automatic Stop  
is off, the humidifier will keep running on  
Low mist level when the highest target  
humidity level is reached.

Note:  
Use a tissue or cloth to clean the nozzle  
regularly.  
Do not add essential oils, water treatment  
liquids, or third-party water filters into the  
water tank or base chamber. Only add  
essential oils to the aroma pad.

Problem  
Possible Solution  
Plug in the humidifier and turn it on.  
Add purified or distilled water to the water tank.  
Humidifier doesn’t turn on,  
or turns off unexpectedly.  
Check to see if the humidifier is in Auto Mode. Depending on Auto Mode  
settings, the humidifier may automatically turn off when the humidity  
level is above the target level.  
Turn the mist level to a higher setting.  
Fill the water tank.  
There may be too much water in the base chamber. Empty the base  
chamber. Refill the water tank (not the base chamber) and place the  
water tank properly onto the base.

If the water tank or base was washed with detergent, rinse thoroughly  
with clean water to remove any detergent.  
Storing  
Follow the cleaning instructions (see page  
before storing. Store in a cool, dry location.  
The humidifier uses up water based on the environmental temperature  
and humidity. If your environment is cold and/or dry, the humidifier will  
run out of water faster.  
Humidifier uses water too  
quickly.  
If the humidifier is new, unplug and rinse all parts, then place in a cool,  
dry place for 12 hours.
