Aeotec DSB45 Z-Wave Water Sensor @ Bigbruin.com
 

The setup of the Aeotec DSB45 was extremely easy, and within just minutes I was able to use the Wink app to confirm just how fast the sensor would alert me to wet and dry conditions. I have placed the one DSB45 by my water heater and I am already feeling a bit of peace of mind from just the ability to receive alerts about the presence of water. I will soon add a Z-Wave controlled valve to have the water cut off if the DSB45 sensor ever detects water in that area.
