merossSmart Light Switch Module, DIY Wall Switch Module, Wireless Relay Smart Switch works with Apple HomeKit, Alexa, Google, Remote and Voice Control, No Hub Required, 2.4GHz, 10A, 2 Pack

Got the Meross MSS185 thinking it would be another “smart” switch that only works when the moon is in Virgo and the WiFi is feeling cooperative. Shockingly, it just worked.Install? Pretty self explanatory, follow online link or simply look at the accompanying paperwork that show the correct way to wire. Make sure the main fuse board is off and test with voltage detector before touching anything. Will only fit back boxes that are over 3cm deep, minimum. If the device was thinner, I suppose more people would purchase it as you could fit it into more switches, this, probably its only downside. Switch is solidly built, looks simple.Setup? I scanned the Matter code, and bam, it showed up in my Alexa and Google Home faster than my cat shows up when I open a snack packet. No forced accounts, no app circus, no password resets from 2017. It’s like Meross actually respects my sanity. Setup the way its supposed to be, well done.I have other meross plugs and must say they have never failed on me yet. Numerous ones are more than 5 years old, so I trust Meross in building quality products meant to last. And so the price is justified, I'm confident it will last. You get what you pay.It turns my lights on and off instantly, doesn’t ghost off the network at 2 AM, and still lets me slap the switch physically when I walk by like a caveperson. Even my non-tech family can use it without calling me for tech support, which is a miracle in itself.Personally I installed it on the entrance light, and have set up a routine linked with my Blink door bell. When someone is detected, it will turn the light on. Works everytime. I have Amazon Echo that works flawlessly with it.(Also useful when im away, and set up a routine to make prying eyes think I'm home)Now the rest of my switches are looking at it, knowing they’re getting replaced. Sorry, fellas. Matter works, and Meross nailed it. A few of these and you have a 1930s smart home.

I purchased this device due to the fact I have patchy Wi-Fi connection at times which can make turning smart bulbs on take forever or just not work at all at times. I couldn't believe how much more reliable these are compared to a smart bulb.The package contains a small controller with the required wires, you just need a neutral wire and can be wired in in about 15 minutes after turning off the power to the switches first. They're simple to setup using the matter code and then the switches just simply work. They integrate well with my Alexa network and now not only do I have a much more reliable connection I don't have to worry about the limited lifetime a bulb can give, for around the same prices as a bulb.

The module requires a neutral connection, be aware that that wire may not be present behind many wall light switches. If that is the case it may be possible to position the module within or adjacent to the ceiling rose. Also be aware that a shallow 32mm pattress box does not have sufficient space within to accommodate the module as well as the mechanics of the light switch, use a deeper 47mm box. Unless the existing wiring layout is straightforward the installation of this module may well be beyond the capabilities of the average DIY'er, a qualified electrician however should have little difficulty. Ensure that the Wi-Fi signal at the proposed location of the module is strong before making any wiring changes. If your router supports both 2.4 GHz and 5 GHz Wifi, ensure that the 5 GHz network is temporarily switched off before attempting to connect the module to HomeKit. The configuration process itself is pretty seamless.In my experience this device works very well and can easily be incorporated within HomeKit automations. I can make no comment as to its long term reliability however - time will tell.

Really good product. Easy to use and comes with short connection wires to easily bridge the existing connections.It integrates easily with smart home controls

Horible Product, This product works but at minimalist as much as possible, The Meros App is also very minimalist as it can get, you can't create schedule, view on/off logs, set default status after coming on, these are base features in apps like SmartLife.The Meros app also logs off everytime and forces you to sign, unlike Smartlife or SmartThings by samsung, they never log you off, its in phone for god sake.I strongly advice to buy Shelly 1PM Gen3, its cheaper, strong brand and 100x beter features including Power monitoring
