An ideal spot monitor, the LTV-WL1 Spot Water Leak Sensor with Ambient Temperature is essential for your early-warning alert system. Place it under sinks, in laundry rooms, next to sump pumps, or even beneath that notoriously leaky houseplant you refuse to give up on. Its sensitive metal contacts detect pooling water right at the source, aiming to give you early alerts through the La Crosse View app* before minor issues escalate. It also monitors ambient temperature for potential freeze risks—offering another layer of awareness, making assurance claims far better than the alternative. 

*Bridge Gateway or Wi-Fi Weather Station required for remote alerts and monitoring.
