CMARS Smart Plug, ZigBee Switch Mini Smart Outlet Works with ST, Alexa, Echo (4th gen) Echo Plus (2nd) Google Home, Works as a Range Extender, Hub Required （2 Pack）

I bought a bunch of different versions that claimed to work with Samsung Smartthings. They either didnt work or required an additional intermediary app. These ones however, worked perfect with Smartthings.

A reliable well made product in a great form factor. Ive been using these for almost a year now with no issues whatsoever. Very easy to setup.

Works well with OpenHab. I would not put these anywhere a child might be able to reach them because the outer cover seems to only be held on by one tiny plastic tab which apparently breaks fairly easily when pulling the unit to remove it from an outlet. When the cover comes off the exposed copper is a very serious electrical shock hazard. Refer to attached pictures to see the one tiny broken tab and the exposed internals.

I have about 50 devices connected to ST hub, so I am not new to pairing devices. The instruction is app tells you to hold button until you see red flashing light. Well in my case this didnt happen for both plugs. It would reset /purple/blue and it goes to solid blue. Somehow i was able to pair it after several tries. Now it is working fine , but I wont order similar type of plugs again ( there are several of them here on Amazon under different brands)

The outlets would pair up but would show up as an unknown device and not able to be used, although it would show up under my smartthings account. This was with the new Smartthings app. The 2 outlets did show up using the old Smartthings app and were fully functional. To fix, I had to use the migration function within the old app, then they showed up on the new app. Apart from that, they seem to be working well controlling my xmas lights.

I bought these to complete my ZigBee Mesh Network that was not very strong for a light switch in the basement. Added one on the opposite side of the basement, and another at the top of the stairs and now I have no issues with the light switch. Going to add a couple more for the main and upper floor.

I connected these to SmartThings for some easy automation. I know the specs are posted and they are accurate but I was hoping these were a little more low profile than they actually are. So far, no issues with connectivity nor function. I would recommend these as a cheaper alternative to replacing an outlet and definitely for those that can’t wire a switch or outlet themselves.

I like zigbee products because it is a mesh network and it doesnt take up bandwidth from the wifi. As I build out my zigbee network it will become stronger and stronger. Soon my network will overtake my neighborhood and then the neighborhood coffeehouse. I will be the envy of this city.

They work wonderfully, paired effortlessly, and even show up as on-off lights in the hue app, so you can control them with the various automation features.

what can i say? it works. it repeats zigbee signals so my whole home has coverage aswell as acts as a smart switch. i do wish the formfactor was a little slimmer to allow for any plug to be plugged in on the other outlet. but it works well. the led is a little annoying if you have this in a bedroom, but that can be fixed with some black tape. so this is a good buy
