How it Works 

When temperatures spike, indoor air can become dangerous due to the mixture of high heat with sun. Couple that with the fact that heat also increases humidity and moisture issues, causing more risk via mold and allergens.

Conversely,when temperatures drop, pipes freeze and damaging water damage ensues. What do you own that’s worth protecting with a wireless temperature alarm?

Worked 2 days after installation. Saved my basement from flooding.

I had lamented for the last couple of years that there was no way of knowing the status of our sump pump, while we were away from home. Battery back up units just didn’t have the capacity to keep things dry. With the PumpAlarm I can know immediately when a problem begins and initiate a response before things get out of hand.
