Product review (2 stars): Easy set up
Easy set up, but found that the alarm notification feature sends to e-mail only.  Disappointing. The app needs to have an alarm to set off on your phone app.  Also, only one  sensor at a time  can have a custom low temp alarm. Again, the alarm gets sent to an email. Worthless info in the middle of the night when temps fall below freezing and you really need to know.
