Is there a low temp monitor that uses a long running flashing light that could be seen by a neighbor? Would have to operate on battery in case low temp is because of power outage. Thanks Nick
This is not the one I bought which was adjustable but should work for you. FREEZEFREE
The ones I bought were Honeywell CW200A Winter Watchman units but I don't see them on the Ace site either. They did have to order them but they found them in their catalog.
