Please check if the Coway Airmega and your Google Home device are both connected to a stable network. If the problem persists after fixing the possible network issue, determine which device is not working properly by checking the Coway Airmega using the iOS/Android application and other (non-Airmega) commands.

If the Coway Airmega application is not working, it may be due to the following reasons:

1. The server may be down (notification will be sent for scheduled maintenance). If you receive a notification of “Server maintenance. Please try later,” it means that we’re working on the server and should be back up in few hours.
2. Check if the Coway Airmega is powered on. Coway Airmega will only recognize command(s) to power on when the device is off.
3. The device may not be plugged in.

If the problem persists, please contact us, we’re here to help!
