I have a smart plug in my dining room into which I plug in a light. This works fine using vocal command to turn on and off.

I have bought a 2nd smart plug for the dining room to control the other light. I have set this up on the app and created a group for both devices.

Using the app on my phone I can power on and off both lights. However, I cannot get the vocal command to turn both plugs on and off.

Am I asking it to do something that is not possible or have I not set it up correctly?
