Mpg, Have you played around with Alexa groups at all? They were pretty basic at first but work “ok” now. If you put the Alexa for the room in the group I know the “Alexa lights on” works well generically in multiple rooms. The same is claimed & may be true with other devices. If you go into the app there is help for groups that is much much better than when it first came out. You can even nest groups now.

Of course the specific answer to your question is above. I’m curious to ask why are you using a different account for each Alexa. I have 8 units in my house using the same Alexa skill -> portal -> ISY. Is there a security or control issue you are concerned about? Interested; one of us may learn something here, likely me.

Besides organization does anyone know any feature differences between scenes and devices on the Alexa?

Can verify the same workaround. Change to light/device from scene. (remember to 'forget' the old scene and 'discover' on the Alexa app or website). Only risk I can see here is now you could tell Alexa to set a scene to a percent on. Not a big deal.
