If you are having trouble pairing the iota to your account, first try the following:
Turn the iota on while the phone is searching. Make sure to press very hard on the iota logo with your thumb.
You will hear a rising tone when the iota is turning on and a falling tone when the iota is powering off. The iota needs to be in the same room as your phone.
After a few seconds, you should see the app screen recognize your iota.
If the problem persists, please submit a support request.
