Product review (1 stars): Buyer beware
Gateway went into death mode after one week( flashing red / green).  After a lengthy factory reset, the gateway and sensors worked for about three hours before crashing again. Tech support will not answer phone or reply to voicemail.  Pretty much a waste of $100, you might even call it a scam given the amount of negative reviews I am now discovering.  Also sensors are off temp by about 10 degrees f. Please do not buy this you will be very disappointed.
