Power plug H2 UK can’t add to Alexa app

I received two Aqara power plugs H2 UK yesterday.

I removed my previous plugs first from the Aqara app, their own app and Apple home. And the Alexa app.

I then added these two new plugs to the Aqara app and Apple home, all working fine, but I cannot add them to the Alexa app, it cannot find any new devices, i tried removing one plug and adding it again but I get the same issue.

Any ideas why I can’t add them to the Alexa app please.

Just to add the plugs are in Zigbee mode which is the mode I want to use.

Also did a factory reset on one of the plugs but still no joy with Alexa still.

hi there, please keep an eye on your inbox, our support will reach out to you shortly.

I got the email thanks, but after spending the weekend troubleshooting I ended up resetting them and putting my previous plugs back in place.

So they are going back for a refund.

Hi, before resetting, you disabled the “prohibit device removal” option on the Aqara gateway. This may be the main problem for you

I have no idea where this option is so can only assume it is disabled by default.

No, it is almost always on. What Aqara gateway do you have?
