I liked this but it has already quit on me. I’ve had it less than a year. It wasn’t used much but it was nice to have available.

Getting the setup sequence right is important - otherwise, it may appear that the device wont show up in the Meross iOS app. Even when it shows up in Homekit. Heres what I found (after some trial & error): First You must have a separately broadcast 2G network, the Meross only has 2G (and the instructions make note of the requirement for a 2G network) - a combined 2G/5G broadcast network wont work. Your iPhone has to be on the 2G network when you added the outdoor switch to your network/homekit/meross app. Second I have my IoT devices on a separate VLAN with firewall rules that prevent crossover from the IoT VLAN to my regular network (I do have firewall rules which allow my iPhone to connect to the IoT VLAN - one way only). Dont try to install and add the Meross app from the App Store - do this AFTER you have connected the Meross outdoor switch to Homekit. To connect to Homekit Connect your iPhone to your 2G network and turn on the Meross outdoor switch - you should see a green/orange light blinking (to reset the Meross, just hold down the power button until it resets). Under Settings, Wi-Fi, you should see the Meross_SW_XXXX setup new device -- click on that, you should see a dialog box with a request to add it to Homekit and WiFi. Once you click on allow/continue, next up will be Homekit. in Homekit, scan the QR code on the side of the outdoor switch or box. It takes a while to add it to Homekit. Once it it is added to Homekit, then download the Meross app from the iOS App Store and follow the app registration and installation instructions. The Meross MS620 outdoor switch should automatically be included in the available devices to setup in the Meross app. If you try to add the Meross app first and then add it to your network or Homekit, well, that didnt work for me. Only adding to Homekit first, then installing and adding to the Meross App worked. Why should I care if it is in the Meross App vs. Homekit? Unless I open some more ports (more firewall rules) to allow the Meross outdoor switch to send data back/forth across my IoT VLAN and regular network, Homekit automation wont work (e.g., turn Holiday lights on at dusk and turn off at dawn). You will be able to turn the switch on/off within Homekit (manually, just not via automation). The Meross app, with its own Routines (e.g., on at dusk, off at dawn) is able to send automation to the switch when it is on the regular network (i.e., non IoT VLAN) - provided you have the firewall rules setup to allow one way access from your regular network to your IoT VLAN.

Usually, HomeKit devices are trivial to set up. This one was just weird. But once I got it working, it has been bulletproof. A good device at a great price, as long as you’re willing to fiddle a bit to begin with.

I have two to control Christmas driveway lights and outdoor Christmas tree lights.

I first tried Meross when I bought a couple of their Apple Homekit compatible controllers to automate some old style garage door openers. I was impressed with how easy they were to install and how reliable they were. I bought this weatherproof outdoor outlet so I can integrate my Christmas lights with Apple Home. The controller was easy to pair and competitively priced.

We had a failure on this switch for unclear reasons. Contacted customer support and warranty replacement was shipped in days. Great warranty replacement process.

I bought this to schedule lights we have on our deck to go on and off with home automations in HomeKit. The setup was very simple and what you would expect from any HomeKit enabled product. I simply plugged it in, opened the Home app, scanned the HomeKit sticker on the side of the plug, waited a few seconds, and then assigned the room and names for the outlets. I’d say it only took two minutes to set it all up. For those reviews saying it does not work with HomeKit, they clearly don’t know how to do it. After setup, I was able to add to my automations and control the lights on and off my network, as I have multiple Apple TV’s and HomePods that act as hubs. I’ve only had it running a couple of days, but will update on how well it holds up to damp conditions and rain. At this point that’s the only thing I’m worried about based on other reviews, but happy so far.

It works as advertised, not issues.

I now have several of these devices in my HomeKit network. I am slowly replacing other outdoor switches as they are much less reliable, requiring periodic unplugging and replugging to get them to respond again. These Meross outdoor switches stay connected and work as advertised. I dont think I have had a single disconnection with them yet! Once or twice I have had to struggle a bit to set them up initially, but in those situations a second try always worked.

These plugs were the easiest to setup, configure and operate.
