    Setup is confusing - for IoT on a separate VLAN (w/firewall rules) AND/OR combined 2G/5G network

    Getting the setup sequence right is important – otherwise, it may appear that the device won’t show up in the Meross iOS app. Even when it shows up in Homekit.
    Here’s what I found (after some trial & error):
    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 won’t work. Your iPhone has to be on the 2G network when you added the outdoor switch to your network/homekit/meross app.
    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).
    Don’t 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 didn’t 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 won’t 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.

    Repeat purchase- good smart plug!

    This is the second one I have gotten- easy to install and connect in minutes! There is an app but I have mine through Alexa and also HomeKit for voice control.
    This is on the back deck to control lights automatically in evenings. No issues, good quality. This is our second purchase, I liked the first so much we added another to a different area.

    Easy to install/Worked partially. Mine was defective-

    So i bought this (not sure if i bought used or brand new) but it was SUPER easy to setup. Yes you can use the Meross App on your phone to set it up, but if any Apple Homekit has that little rectangular QR code sticker… you can instantly add that to Homekit. Thats what that QR is for.
    This product DOES NOT need the Meross app, will setup straight into your Homekit app.
    3/5 stars because only 1/2 plugs worked, and you can hear the audible click noise when the Surge protection clicks on and off. It would do this constantly. Im returning this defective product and ordering the same exact product, because it was super easy to setup and works easy. Also went through 2 separate Oklahoma heavy T-Storms… So i assume its weatherproofed quite well.
    Tip: When setting up in Homekit, make sure to label each outlet as ‘Outlet 1, Outlet 2, or LED lights, etc) otherwise you will forget which one is which.

    Great HomeKit Outdoor Smart Plug

    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.
