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）

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.

My whole house is quickly becoming automated with these smart devices, all centered around the SmartThings hub. I started by outfitting all of my light switches with ZWave specific devices. I have a number of other devices as well such as door sensors, locks, etc. I still had a few lamps around though that werent on switches, so I got these smart plugs to control those. These outlets and nice and small with a flat front. Perfect for hiding behind bookshelves. Its worth noting that these outlets use the Zigbee protocol as opposed to ZWave, but both are fully supported by SmartThings. I had no issue getting these to join my network. Simply plug it into the wall outlet, then in the SmartThings app, let it find any new devices. It came up almost instantly. If you are not a SmartThings user, supposedly you can just plug these in and have Alexa discover and control them. Ive not had a chance to try that. Once you add these to your hub, the possibilities are endless. Currently I have these lamps come on automatically at sunset each day. You could also automate turning these on when someone arrives home at night, etc. Great little devices. Not to mention the 12 months replacement/refund warranty on defective items. Would definitely purchase again when needed.

I got these to uses as repeaters on my ZigBee network. I am using home assistant (ZHA). The system found them quickly and joined the network. but it is not stable will only stay on the network 3-4 seconds before it drops, then it will come back and drop again. Completely unusable.

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.

Surprisingly good, especially for how little they cost. Paired quickly with Phillips Hue hub and integrates perfectly with all the other bulbs in the house. The compact size is great, much smaller than other smart plugs. And the status led, although somewhat bright at least stays steadily lit unlike the sonoff plugs that are constantly flashing. Very happy with these plugs. They allowed me to ditch the wifi plugs I had controlling string lights indoors and out that would regularly lose connection. Now my non-smart light strings are just as reliable as the ridiculously expensive hue stuff.

Because this is a zigbee smart switch, it is very easy to add to a smartthings hub without any additional app beyond the Smartthings app. It is the easiest Ive found. Just plug it in, open up the smartthings app, and scan for new devices. Much better than wifi plugs.

The plugs seem to work well so far - Im using them for a couple of small fans. Worked fine with Zigbee2MQTT - just set it to allow devices to join and plugged them in, then they joined instantly. They show up as eWeLink SA-003 in Zigbee2Mqtt and Home Assistant.

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!

I use these plugs with my Hubitat smart home hub, connected immediately, works perfectly to control a circulation fan i have setup in my bedroom, and strengthen my zigbee network.

Works with home Assistant. Easy to set up.
