Setting my location in the house with a variable / passing variables / alexa awareness

I have haasa setup and i want to be able to launch a scene by simply saying “turn on plex” and not “turn on plex in the living room” or turn on plex in the bedroom" and creating multiple scripts and routines for multiple rooms.

Ultimately i would love for home assistant know which alex i am talking to and automatically assume i want the job done in the room i am sitting in.

I dont know of a way to “capture” any device address and utilize that information to pass to a script inside home assistant. If someone does, please let me know.

As a work around, i was thinking thinking of creating a script that sets the variable.

For example, “alexa, i am in the living room” and then a home assistant scripts set my location variable and then i can simply launch my special scripts like “alexa, launch plex” and then it would launch my home assistant script to launch plex on my roku in the living room"

Any ideas? Capture a device address from which alexa is talking? and Set variable with a script that can be called from another script later on?

Thanks y’all. Any help or direction would be appreciated.

Thanks In Advance
