Based on 34 years of dealing with winter weather, power outages and furnace issues, I still think that the best bang for the buck is the Freeze Alarm. Yes, it does need a land line. We have never gone with cable provided phones since often when the power is out, the cable and cable phones are also out. Fairpoint land lines are often operating when the power and cable are out. An exception was last year’s wind storm, but the land lines were back up days before the cable was. We now have a whole house generator, but the Freeze Alarm will still provide notice of furnace or propane supply issue., or a generator failure.
