tl;dr - Meross hardware easy to install, meross software is easy to use, Apple Home setup is more of a meh. Make sure you think about what electrical wires and space is available before buying these and while the Apple Home compatibility is good if you're already using it, it didn't add much value for an iPhone user who is using Amazon echos as my smart home hub / voice commandsAs a disclaimer, I've been adding smart switches to an old 1930's craftsman home that has probably had a couple of electrical jobs done before I bought the house, and not all that surprised that the previous owners had done some interesting solutions, but that has for better or worse, made it possible for me to work though some of these modern era upgrades, and even since I started adding smart plugs and smart switches to the house, I've been loving it. I have had some previous generation meross products (some of their smart plugs) and while everything eventually gets added to my echo commands, it is nice to stick to some same platform parts to bridge the gap between hardware installation though its network setup before the final connection to Alexa.So lets start with the hardware. It is straight forward and easy to connect. The instructions are fairly clear, the requirements for a neutral line is clear from the official posting, and while adding said neutral line probably isn't the easiest job, you might want to factor in the size of the gang box you're putting it in. I don't think I'd had any issues with replacing a single switch, but two smart switches in a 2 gang box with both the wires to the lights, the fan, a extra set of wires for the neutral line, plus all the wire nuts that come with the switches means that there's a lot to fit in a box and you are no longer able to use some of the tricks that you can with screw terminal switches. While I was able to get everything in there, it was a tight fit and I did have to open it up to fix a a wire nut that I think the wires got shifted around when getting it all into the box. Now again, the box I had problems with is a old work box, and it is the standard if not slightly smaller size, so if I was doing it again, I might have gotten a new box, but something future buyers might consider as a potential problem. Wire nuts provided are pretty universal. No problems connecting with 2 14 gauge wires, nor with 4 wires, but the size of everything does add up. Other little nit picky stuff is would sort of prefer more standard switch plates. While I like the idea of screw-less surfaces, I was putting these into 2 switch box and had to get a 2 switch switch plate for them. Not expensive, and not a surprise, but would have been nice to have plates I could use easily on other boxes or skip it outright and drop the cost another dollar or two for parts that I don't need.With all the wiring done, it's installation time. As noted, I've used other meross smart devices in the past, and the installation guide in the OS is nice, although repetitive when you're installing multiple devices. With the Apple Home feature, it was nice that my iPhone was detecting the newly install devices and instantly offered to help connect them, but honestly mixed bag. The code reader for the stickers on the devices never worked, but easy to figure out which switch was witch with the easily viewable home codes and MAC addresses. I did have a few attempts with Apple's Home system spitting out various issues while setting up the device, but I suspect it's more of an Apple thing than a Meross thing since once I did get them setup for my home network (and on my iPhone it HAD to be though Apple's Home app setup) it was just a couple quick commands to the Meross app before they got paired with my Alexa commands.
