That Freeze Alarm has been working out great. You can call in from out of state and it tells you your house temperature.
Has a call out to your out of state phone, a friend, or neighbor's phone if the house drops below 50°.
Has a little 9 volt battery if the power goes out, it will still work.
Even calls out if the power goes out. Pretty handy deal to make sure house does not freeze up while away.
I always drain my water down, just as a saftey backup.
My internet service stays on with a computer and 3 web cams, then I can log in from out of state, see the inside temp, and look out the basement window to see how much snow is on the ground.
Since I got the Fiber Optics Internet Service, this remote access is working so much better, rock solid connection.
Technology is so Great . . .
