Hi OON7,
If during setup the wifi logo is not blinking, you will need to reset the wifi by pressing auto and fan speed keys simultaneously until the wifi icon starts flashing. Looks like you had it figured out.
The AQI history will take some time to show up from the moment you turned on your device (about 1 dot per hour). The top half of the screen is showing you the outdoor pollutant concentrations for various common air pollutants. We do realize the explanation is lacking in this version and we will improve that in the next app update.
