Greetings all. I have done quite a bit of research and I can't figure out how to fix my problem with Homekit. Does anyone have a suggestion for me?

I originally set up a homekit home for my daughter in her attached apartment. Worked great. Set up lots of scenes and automations. Now that I am setting up a homekit home for my main house, I can't get Siri to know which home I want to control.

Each home has it's own Homekit hub and it's own Caseta hub but we have a shared network and physical location. I have tried selecting the correct home in the home app but that has no effect. Everything keeps defaulting to

I'm trying to avoid having to specify the "home" with every command through Siri which is necessary when each home has common room names (kitchen, dining, etc.)

Thanks.
