We have a home security system with freeze and flood sensors along with the usual door and window sensors. We leave the heat set at 50 degrees. The system uses the Verizon data network to notify us and the monitoring company of any issues.
The only notification email we got was for a one hour power outage.
When we got home a week ago the batteries in two of the three thermostats were dead.It appears that the units held the 50 degrees though since it got down to minus 19 or so and I don't think the one zone with good batteries would have heated the whole house.
I replaced all the batteries with new date codes before we left and they are supposed to be good for three years or so. They held up fine the winter before so I guess I got a bad lot of batteries.
