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.

Good-looking product, but my Alexus hub isnt new enough to be able to recognize these plugs.

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.

I’m got these for use with a SmartThings hub and found that they were so easy to pair. Plug them into the outlet and they will immediately be discoverable in the SmartThjngs app where they can be setup with one click and you’re done. They work exactly as advertised and are much cheaper than competitors (often half the price). I’ve used several other brands and these paired easier than any including SmartThings own outlets and they are just as responsive when manually controlled from the app or as part of an automation. The only downside I see is the indicator light is fairly bright. I use one in a bedroom and it throws a bright glow in a darkened room. I used a bit of electrical tape to cover the light and problem solved. I highly recommend these and I’m looking for something else to automate so I have an excuse to buy more!

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 run OpenHAB on a Raspbery PI 3, with a HUSBZB-1 USB Hub as controller. I could connect the plugs with no issue.

Easy to operate/integrate with my Samsung smart thing hub and very reliable

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

This works reliably and well, but the max current makes it good for lights, no good for appliances and heaters. If you need a heater, get the Sylvania Zigbee smart plug instead (good to up to 15A/1800W)

The two CMARS Smart Plugs were exactly what was needed. I was pleasantly surprised how easily they paired with the Echo Studio I was using. I had expected a little more troubleshooting than I experienced. I use one to power my home entertainment system power strip so I do not need to turn off the light, TV, and system separately. I just use a voice command on my Echo Studio. Edit: One has since broken after owning them for about two months. When it works, its great. But having such a short lifespan is concerning. The one thing still outstanding is longevity. I plan to use one for more active use of on and off than another. In theory they should be last the same amount of time but I will update if the more used one faces issues sooner than later. Edit v2: Both are now non-functioning and useless. I admit that using them in conjunction with an extension cable may have been the issue but there were no warning that I noticed that spoke against it. Be warned they may die early.
