MOESMini Smart Light Switch Zigbee Module, Requires Neutral Wire, Toggle Switch Flush Mounted, MOES APP Control, Compatible with Alexa and Google Home - 2 Gang 10A

I have used Meos products before, and they are pretty good. I have 3-way light switches, and I wanted to make two of them smart. At first, the wiring diagram was a bit confusing, but then I labelled the wire and started to draw on paper and replicated the same on the main sockets, and it worked like a charm. The attached diagram helps users pair two lights and switches with Meo's smart module.

I'm not sure about this one. It looks pretty decent, but I couldn't get the S1 input to work properly (it kept on clicking on and off when an otherwise dead wire was attached).This device has a beeper (buzzer) inside it - quite handy for when you're setting it up, but if that thing beeps when the device is hidden away behind a light switch it's going to get really annoying really fast.I do rather like that it has a sort of clip to hold it in place - if you need to attach it to something, it's a really neat way to do it. All in all, looks good enough, but it's not for me.
