Product review (4 stars): Great product but don't expect support if you have a problem
I have a number of remote properties where I have installed these to monitor key temperature areas against freeze up. For example I attach the probe to the heat water line and get an alert if the temperature drops to below 80. If it does I know I have a boiler problem and need to call the repair guys. This alert comes well in advance of the low temperature alarm service monitoring which requires the house to drop to 45. When they work they are great. However if you are having problem it is impossible to get support from La Crosse alerts either by phone or email.
