It is difficult to figure out how to set alerts for temperature. I did finally set an sheet and I never received a message that temp Has gone below the degree I set. Thankfully I check every day since this is a second home and the temps are below freezing so water pipes could freeze.
One of the best product I've ever purchased. I can be hours away from home, and still activate are deactivate my appliances through the phone app... Very much worth it...
