Simple solution to provide a freeze alert for remote sheds
We have a number of out-buildings for well pumps, DEF huts, etc. that aren't regularly occupied and do not have WiFi available in them. We use this to turn on a strobe light on the outside of the building if there is a heating issue. Works great for us.

Simple, Effective and Reasonably Priced
I simply plugged this into a wall outlet inside our pumphouse and plugged a red strobe light into it that is visible in the nearby office. I have it set to 45° F and am confident that will alert us in time if our heater fails in the pumphouse.

Minimum temp control not accurate
Set control to alert at 48*, it went off at 56*. It cannot be trusted.

Excellent product!
Alerts neighbours at cottage there's a problem with heating system. This product has saved us from frozen/busted pipes on a few occasions.
This product should be available in Canada! Excellent service, fast delivery!!
