Solid switch that takes up less space
If you’re looking for a decent smart light switch, these work quite well and take up less space in the gang box than others smart switches I have tried. Installation is the same as any other switch except of course that these require the addition of a neutral wire. My house was built recently enough that this was no issue but if your home doesn’t have them, there is an option available from another brand that doesn’t require the neutral wire. I installed 25+ of these including some of the standard 3-way style as well as some of the single pole dimmer style switches. All of them worked and have had no connectivity issues to my network at all. I think that the industry in general just hasn’t figured out a decent solution to properly dimming LED fixtures. Having said that, the single pole dimmer switches work well enough but still leave a little to be desired. I do like how the dimmer gain level adjustment is done through the app on their single pole dimmer and not on the switch itself though. The 3 way dimmer switch uses a master and a companion switch and the dimmer gain level adjustment is on the back of the master requiring removal of the switch to adjust it. I was unable to get the 3 way dimmer or the replacement switch I was sent to ever dim my LED recessed lights and eventually replaced it with their standard 3 way smart switch and a manual dimmer on the other side. I am only using the app to control the switches and schedule things like the porch light to come on and off so I have no input about compatibility with Alexa or Google but their app works well and is simple enough to navigate. Overall, these work great and have never had any network connectivity issues which are the primary things a person would want in a smart switch so I gave them 5 stars. I will update my review if I have any early failure issues but so far so good on reliability.

Works as advertised
I now have 22 Meross 2-way smart switches installed and connected to Alexa. I chose them because they were less expensive than some other brands with the same features. Installation was fairly simple. The app contains all of the instructions, though the wires coming out the back of each device are well-labeled. I never used the instructions for wiring the switch. The 2-way switch has the power wire, ground wire, neutral, and a carrier (4 total). I have a home built in 2006, so every box has the neutral wire, making this easier. There are two problems that make installation more difficult: 1) the wires coming out of the switch are only about 3 inches long. In a 4-gang electrical box with all of the neutral wires tied together at one end, this means that it’s impossible to make the short neutral wire from the switch reach the house neutral without adding another extension wire; 2) the Meross switches take up a lot of space. If the electrical box is shallow, or if there are multiple switches in the box, then getting the Meross switches and all the wire connectors into the box can be tough. It is possible that all available smart switches have about the same footprint, so this may be a universal problem for smart switch installation.The Meross App working on an iPhone had very easy-to-follow directions for linking the switch to the app and giving it a unique name. Alexa doesn’t list Meross as an available company, but I simply chose “other” for company. And Alexa found all the Meross switches without any problem. Meross allows the switches to be grouped in “scenes,” such as “leaving the house.” With each scene, each device can be set to on or off. It is also possible to set up schedule for each device to either turn on/off according to date/time, or to automatically turn off after so many minutes being on. It is nice to look at the app when on the road to see that lights are turned out, or to turn lights on when coming home.So far, I have 28 Meross smart switches, four smart plugs, and a smart garage door opener all connected, and they have been performing flawlessly, either with the Meross App or with Alexa. They use some data, but it is not slowing my internet down at all. I recommend their smart products.
