My smart air purifier isn't connecting to the VeSync app.
Make sure your phone has Bluetooth® turned on and is not currently connected to
•
another Bluetooth device.
During the setup process, you must be on a secure 2.4GHz Wi-Fi network. Confirm
•
that the network is working correctly.
Make sure the Wi-Fi password you entered is correct.
•
There should be no spaces at the beginning or end of the password.
◦
Test the password by connecting a different electronic device to the router.
◦
If you're manually typing in the SSID and password, double check that both are
◦
entered correctly.
Try moving your air purifier closer to the router. Your phone should be as close as
•
possible to your air purifier.
Your router may need to be at a higher location, away from obstructions.
•
• Make sure your air purifier and router are away from appliances (such as microwave
ovens, refrigerators, electronic devices, etc.) to avoid signal interference.
• If you're using a VPN, make sure it's turned off while setting up your air purifier.
• Disable portal authentication for your Wi-Fi network. If portal authentication is enabled,
the air purifier will not be able to access your Wi-Fi network, and setup will fail.
Note: Portal authentication means that you need to sign in to your Wi-Fi network through a
web page before you can use the Internet.
My air purifier is offline.
Make sure the air purifier is plugged in and has power, then refresh the VeSync menu by
•
swiping down on the screen.
Make sure your router is connected to the internet and your phone's network connection
•
is working.
Delete the offline air purifier from the VeSync app. Swipe left (iOS®) or press and hold
•
(Android™), then tap Delete.
Reconfigure the air purifier with the VeSync app.
•
Note: Power outages, internet outages, or changing Wi-Fi routers may cause the air purifier
to go offline.
