Hello, @stephen.murrell . . . I have moved your post to this thread since it is all related to the issues everyone was having.
I am sorry the smart lights are not responding to voice commands.
Since you have tried the trouble shooting method and it is still not working, I would suggest making a video of what you are attempting with reconnecting and EMO not responding to the commands, then post a link here so that maybe we can try to help you troubleshoot.
Let us know. Thank you.
