Ensure that your diffuser is plugged in and turned on. Often, this error can be resolved by simply powering the diffuser off for about 30 seconds using the button on the back, then powering the diffuser back on.
TIP: If you have just connected to the app, there may be some delay in communication between the app and your diffuser. Wait for up to an hour, and the message should resolve on its own.
If the diffuser is turned on and you've tried the above solves, this may be an issue with your Wi-Fi Network. Since the Aera Home Fragrance uses your home Wi-Fi, check that you can get online with another diffuser in your home. If you’re using a cell phone, make sure you don’t use cellular data to test your connection. You may need to move the Aera closer to the router to get an uninterrupted signal. If you can’t connect, try using a different device to double check. If you can’t connect with any diffuser, contact your internet service provider to check the service status in your area.
TIP: To make sure you’re not using cellular data, turn on Airplane mode and then turn on Wi-Fi.
