I helped set up some Meross smartplugs that were being used to automate home functions. What follows is how I was ultimately able to connect them to an Eero 6 Pro router.

The Problem

When opening the Home application on an iPhone or iPad, and scanning the QR code that was on the smartplug, I received errors that the process could not be completed. I tried resetting the phone, letting the Apple iOS devices linger for up to 5 minutes to complete the connection, and resetting the home hub to see if that would help. In no case were these measures successful.

The Solution

I connected the smartplugs to the Eero 6 Pro network (and Apple Home app) by modifying some of the router’s settings as well as not using the QR code to set up the device.

Specifically I:

1. Opened the Eero app and temporarily disabled the 5Ghz radio and turned off the WPA3 experimental feature.
2. Activated airplane mode on the iOS device I was using to connect the Meross plugs to the Home app.
3. Performed a hard reset on the Meross plugs (this involved holding the power button for 15 seconds. I heard a ‘click’ sound when it reset). I checked to ensure that that the LEDs were blinking between amber and green colours.
4. Reconnected the iOS device to the Eero 6 Pro router. This ensured that it would establish a 2.4Ghz connection.
5. Opened the Home app on the iOS device. I then selected ‘Add Accessory’ and, then, the ‘More options…’ link.
6. In the new options, I saw one that read as a smart plug, and another that had Meross in its name. I choose the one with Meross and then entered in the 8 digit code above the QR code on the smartplug when prompted. I did not connect using the QR code/camera.

The Meross smartplug subsequently connected to the network. As a note, I had to wait up to 30 seconds before it finished its setup.

Meross Smartplug Firmware Update

With the Meross smartplugs connected to the network I updated their firmware. To do so, I:

1. Downloaded the Meross app and create an account.
2. Linked the plugs to the account by tapping the ‘ ’ icon in the Home panel in the Meross app, granted the application permission to scan your local network, and then added the switches.
3. Once they were added, I navigated to the ‘Account’ panel and selected ‘Firmware update’ under ‘System’. I then followed the on-screen instructions to update the plugs.

By the conclusion of this I managed to join the Meross smartplugs to the Eero 6 Pro network, as well as updated their firmware. Hope that this helps to solve any problems you’re encountering with them!
