How do I connect my product using Bluetooth?

I cannot connect to a public/open Wi-Fi spot without a password. What is the problem?

I cannot connect to my home network. How can I check if my signal is strong enough?

Should the main network always be 2.4 GHz or only for connecting the product? 

I get a time-out message when trying to connect to the app.

My Whisper Flex (Ultimate) won't connect with the app. What can I do?

I want to create a schedule on the app so that my Beam, Beam Mini, Blizzard, Edge or North automatically turns on and off from 11:00 p.m. to 9:00 a.m., but I get the following message, "The power on time needs to be before the power off time." What can I do?
