Seen separate threat for SmartThings Water Leak sensor sold by Samsung.com. BestBuy.com and Amazon.com.
However if you looking for 3 or more of those – shop at smartthings.com
they offer additional discounts on pack of three and on pack of five.
Use also coupon code WELCOME10 for additional 10% off.
Pack of five was for me $101.69 shipped and no tax to NJ.
Those best and zero isses for few years I have them.
Adding Zigbee repeater near by expands their battery life and reliability.
Enjoy.
