Saw these on Amazon for $11, advertised as Zigbee switch “works with SmartThings”. No reviews, good or bad, so I was leery but I figured I could return if they didn’t work as promised.
Bought 3 to replace some really old Wemo wifi switches that have been giving me issues. They are setup like an in-wall type of switch but are too bulky to fit in a single gang box. Very tight fit in a a double-gang box when the switch are in there. Stock pictures on Amazon show them used as in a in-line open air setup for lights.
No issues getting SmartThings to find the device, however they were recognized as simply a “Thing” so I needed to logon to the api and change the device type to “Zigbee Switch”.
Pros: Cost, They work.
Cons: Size, that about it unless you consider the “worry” about why are these so cheep?
