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）

My home is less than 2K sq ft, and most of my devices are Z-Wave. I know some people claim that these can be unstable on a Zigbee network, but they work great for me. I probably only have a dozen or two Zigbee devices though.

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.

Paired with ease with my Phillips Hue bridge, shows up on the Hue App once connected then they both auto showed up on my Google home app where I was able to place into a room and then set up the routine to work the plugs. 100% better than the awful GE smart plugs I bought last year. Buying two more of these right now.

These things have never failed so far and purchased 2 more a year later!

They work great, take a decent amount of wattage (I run a water distiller off one of them), and pair great with a Zigbee USB radio via Home Assistant. For day to day use on a timer, remote control, or something similar, theyre amazing especially foe the price. I have 4 of them. The only issue Ive noticed are they tend not to have a lot of range and they dont repeat the Zigbee signal very well. Luckily I had some other devices I could add in to maintain the mesh, but just be aware it may have issues if its AR a long distance / through some thick walls / off by itself.

I have this plug set up to integrate with my hue system for one of my lamps — it turns on every single morning just like the other lights on a timer but does not turn off like the other lights. So it does its job like, 60%.

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.

Great buy. They are easy to integrate with Home Assistant (ZHA - ConBee II) and they act as Zigbee repeaters. I am using them to replace the TPLink Kasa ones that require Wifi to work! Zigbee is so much better! They pair instantly, they switch on and off instantly (no internet lag) and they still work when internet is down. Plastic quality seems good but I still do not know about the life of this product. I will update the review after about a year. Also the do not report consumption, like the TPLink ones.

Ive purchased these smart plugs two times. They show up as model SA-003-Zigbee. The first set, the plugs announce themselves as device type 0x0009 (Mains Power Outlet). ZHA integration in Home Assistant put them under the switch domain. This is all well and good. The second set, the plugs announce themselves as device type 0x1000 (On/Off Light). ZHA integration in Home Assistant put them under the light domain. Not so good, because theyre not controlling lights. Generally speaking you can sort-of work around the difference in domains, but it would be MUCH better if they all had been device type 0x010a (On/off plug-in unit)

These cost-effective zigbee plugs worked as expected out of the box. Im using one to control a lamp in the house, and one to control a string of party lights on the patio.
