To Many Siri's All in one place at the same time?

I have multiple devices on or near me all day long, watch, TV, pod, iPad, iPhone etc. the problem is when you say Siri to ask it to do something or give info Siri does not know which one to use, or how to complete the task. I have this problem as I am single dad with an autistic son who is 15 and also has devices. I know I could turn them off and on but that would be a HUGE HUGE hassle, much less forget to turn it back on, etc. Then I have had to close my laptop because it wants to turn a light on for me, when asked usually to the iPhone etc. That all said I can't figure out what to do, even my watch , and I need these to help me daily for him and me. I can't figure out how to fix this bad situation as to many want to be the "Super Siri" for me. Did I explain it ok? Thank you
