If you are receiving an error stating that "Home couldn't connect to this accessory" please follow the steps below.
This article only applies to WIFIPLUG HOME on iOS.
Cause of error
Most of the time this error is caused by having the Apple Home app open at the same time as the WIFIPLUG app during the setup of your HOME plug. This error message can appear under different circumstances though.
Close both the WIFIPLUG app and the Apple Home app and begin setup again. Please fully close both apps and reset your WIFIPLUG. Once reset, only open the app you wish to use for setup and continue with the setup process again.

Make sure that your mobile device is connecting to the correct instance of the plug. When you are prompted to select which nearby device you would like to setup (this is the step immediately after scanning the code on iOS 11+ or the step immediately before scanning the code on iOS 10 and below) you must select the correct instance of your plug. If you can see multiple instances of the same plug you must select the rightmost option.
You must also select the instance coloured orange and not grey. Orange indicates that the device is nearby and ready to be setup.
To remove duplicate or incorrect instances simply restart your iOS device.
Make sure that you are connected to a compatible Wi-Fi network before setting up your HOME plug. The network you are connected to prior to setting up your plug is the network your plug will be told to join. If this network is incompatible with HOME then you may receive this error message during setup.
Your network must emit the 2.4 GHz frequency and cannot use WEP encryption.
Disable mobile data. In some cases, mobile data can interfere with the setup process resulting in this error message. Please disable mobile data before setup and try again.
Make sure that both your mobile device and router are within range of your WIFIPLUG.
Make sure that your mobile device is running the latest iOS version available.
Check if your plug is still setup in the WIFIPLUG app or Home app. If your plug is still visible in either the WIFIPLUG app or Home app, please delete all visible instances of it.
Power cycle your hardware. Please disconnect your router and plug from mains power for a short while (up to 30 seconds) then reconnect them. Once your router comes back online any barriers that may have been blocking the connection of your plug will have been removed. You will then be able to attempt setup again.
