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）

Its hard to know if these devices were used before I got them, maybe something someone else returned, or if they were just packed poorly. They come in a fairly lightweight glossy-paper-board box, and that box was shipped by Amazon in an unpadded plastic envelope, the consistency of a decent garbage bag. The result is that the retail box was close to destroyed and the 2 devices had been banging around in the envelope. They work fine so far, and since they are plugged into outlets at near ground level, the scratches on them are not that obvious. It is not worth trying to return them, but I find it annoying that I pay for something new, but it looks poor when I get it. They paired almost instantly with my zigbee hub, and the built-in repeater function works well. Adding one between my hub and the front door has helped to make my zigbee lock more reliable.

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.

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’m a HomeSeer user and these modules are extremely dependent and well made. I replaced my Insteon modules with these and what a difference! No signal loss in my 3500 sq. ft. home. The Insteon modules became brittle over time and the cover easy separated from the backplate leaving the backplate still in the ac socket. Time will tell how these modules stand up, but I’m very impressed so far. Highly recommend!

Pairs instantly, the best smart things plug i have found,

Quick inclusion into Hubitat hub and very responsive. I have my hubs on the second floor and these plugs on the first, and they work with no issues. Highly recommend. Only thing to be desired would be power reporting. Take note of the devices you will be plugging in. I replaced WeMo plugs with these. The WeMo plugs could handle up to 15A, these plugs can only handle up to 10A.

I bought a bunch of these about a year ago and they worked fine. However, recently theyve started to fail. So far, three have failed. They no longer respond to commands and cant even be operated from the switch on the unit itself. These are not a good deal in the long run.

I set one of these guys up with the christmas tree and put it on a timer through alexa/smartthings. Works awesome. Setup was super easy and its been completely reliable.

They work really well with Alexa

The plugs all worked out of the box as described and were easily discovered by Alexa. Everything works perfectly!
