The main leakSMART system components are the shut-off valve, remote sensors, and hub. They all use the ZigBee protocol, which uses a mesh network for communication, but does require a hub for control. This review will be handled a little different than our typical reviews. First we will go over the components of the leakSMART system, and then we will go over system performance with their proprietary hub, Iris by Lowes hub, the Wink hub, and then the SmartThings hub.
