Meross Smart 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

This is a pretty good product. Fairly well packaged with ok instructions. It would however be very helpful if the L & N terminals were labeled.I've used mine to control a set of down lights in our garage soffit. It's worth noting that all of the wiring is inside the garage, I assume this could be used outside only if it was stored in waterproof enclosure.Providing you're competent with wiring, this switch slotted in nicely between a fused spur and the set of lights.Connecting the switch to your WiFi with the Meross app is easy enough it even walks you through with connecting/linking to Alexa and Google Home.The Meross app features are minimal, but as Alexa treats the light as a switch, you're able to configure custom routines to control the switch however you like. The switch does not have a dimming function.

These switches are great for the price—easy to set up and simple to use. Anyone invested in the Apple ecosystem will truly appreciate how well they integrate and perform.

These were bought to replace some generic Chinese units from Amazon. They functioned ok, but wouldn’t connect to WiFi correctly without a separate access point.For the Meross units- I’ve bought 5 of these, 4 were ok, but on the 5th the connector where the power goes into basically just snapped off.The connectivity with HomeKit and Wireless (dedicated 2.4Ghz smart network) seems to be flawless and connectivity with Homeassistant also seems to be speedy.The replacement unit is on its way and we’ll see if the others live up to the test of time!

Great product very easy set up and wire can be used for a variety of items I use it to switch on underfloor heating pump Took all of 10 minutes to setup and wire added to app then apple home kit no problems

Work great, basically a smart 2Way switch.

The first one of these I bought connected quite fast and worked for a few hours, then it dropped out and needed to be reconnected, I did this and it again worked for an hour or so. Then it dropped out again and wouldn’t reconnect at all so I got Amazon to send a replacement, this one won’t do anything, HomeKit can’t find it, the terrible Meross app can’t find it, it just sits there with a light which is sometimes green, sometimes green/orange, sometimes flashing green. It’s going to be sent back and I will figure out something else to use that isn’t made by Meross.The physical connections on this are very flimsy as well and don’t seem to be attached to the circuit board very securely, maybe they don’t bother as nobody keeps them long enough for those to break?There are a number of people on forums suggesting lots of strange techniques for connecting these but none of them worked for me, the amount of people saying they can’t connect it and saying to stay away from Meross stuff should have also been a warning to me as well. Anyway, back if goes.

Like the many other Meross kit I already have, this just works perfectly straight out of the box. Simple to wire up and setup. I have a big home and my WiFi is not the greatest but all my Meross products work flawlessly all of the time.

TLDR; Thankfully HomeKit has automation, because this switch simply refuses to connect to the Meross app.I've got a couple of Meross products, and they work great in HomeKit but they're always a pain to get into the Meross app. This switch is even worse for that aspect.Eventually got HomeKit on, via HomeKit (and in future attempts, just adding straight via HomeKit was the easiest way forward). This left the device as unbound in app. Couldn’t add it, it said wait 1min but after several it was offline and broke HomeKit. Had to remove and repeat HomeKit setup.After several attempts, tried a tweak, which was set up HomeKit.,Then use a different iOS device to set up in meross app. Left that for about 15m which didn’t seem to do anything, but the first iOS device could now see it, and could do firmware update. But the firmware update was a 1-shot, I've never been able to get the switch to show up in the Meross app ever again.Crimp connectors are tiny, feel undersized for a 10am rating. Stickers covered the important wiring guide, so didn't know it had to be wired in a certain direction at first. The manual shows the in/out -> but when they're covered on the switch itself it looks like you can wire it up in any direction (which you can't).Firmware update takes way longer than their estimate but as mentioned I've never been able to get the switch into their app ever again to look for newer firmware updates.This will probably be my last Meross purchase because it's deeply frustrating setting them up.
