Review on SmartThings GP WOU019BBDWG Compatible Amazon Google by Xiaomeng Chang

I like this sensor. I bought 2 of these for less than $20. But my whole system of intelligent things keeps turning off for some reason. Sometimes it's just splitters and sometimes it's a hub. Between this issue and the fact that I just realized they cost $76, I now want to throw it all away and switch to another brand! They don't cost $76 at all!
