  • Works Well as Zigbee Router
Size: S40 Lite ZB Number of Items: 1
I recently started a Zigbee network in my house, using a Sonoff 3.0 USB dongle as my coordinator (Zigbee2MQTT on my QNAP NAS > Home Assistant). I wanted some repeaters/routers so my sensors on the other side of the house had a good signal. I tried purchasing both the S31 Lite and the S40 Lite, and both work very well with the latest version of Zigbee2MQTT (automatically recognized and paired, no need to edit your YAML file). They paired immediately as routers, then I reset my sensors and allowed joining specifically to these smart plugs. The signal strength isn't the greatest between these and my coordinator, but I have multiple walls between them (coordinator is in a cluttered closet). The repairing my sensors to the routers has increased my LQI on them. I was hesitant to get these at first, because there are a lot of inconsistent reviews on devices serving as Zigbee routers. But they were on sale, so I bought two S31 Lites and one S40 Lite, and all three work immediately. Very happy with the purchase considering the low cost, ease of pairing, and effectiveness as routers. Recommended for anyone looking to extend their Zigbee range using the same setup as me. ... show more

  • Great, but poor instructions
Size: S40 Lite ZB Number of Items: 4
These work great and I like that they are Zigbee, but wifi. Easy setup if you can figure it out. I didn't want to use their app because I have a Smart Things hub to control it. Ultimately just plugged it in and had Smart Things scan for new devices. Simple. Used one to turn my Christmas lights on and off on schedule via Smart Things app/hub. The QR code on the back of the plug didn't work for SmartThings setup. ... show more

  • Need some patience setting up with Smartthings
Size: S31 Lite ZB Number of Items: 4
I bought 5 of them, and 3 of them weren't immediately picked up by Smartthings. I found that you have to long press the button again and sometimes move the switch to another location (maybe due to weak signal). However, once set up, it works fine. Another issue is that the green LED indicator (connection status) is too bright and the red LED (power on status) is too dim. I thought maybe the red LED was broken but then all five units shows the same thing. ... show more

Got a pack of these to add to my zigbee network as repeaters, and they do the job great. Easy to control, reliable. Easy to pair with ZHA.
