All of this is great...I have had the Freeze Alarm Intermediate for years....but when the power goes out, most also lose phone power and then the freeze alarm is totally useless. It only works as long as you have phone lines. With cable, most do not have backup power. You need to solve the phone problem before having any total confidence in the Freeze Alarm. i have yet to find a suitable solution. Even my security system does not function without phone power. We lost power last winter with the wind storm, but could not get any report from my alarm. Just assumed if i could not get a phone call through, then the power must be off.
