Yes. I regularly ask Siri to add items to my shopping list, to set a timer, what the weather is, to turn on and off lights, to play music, to find a location and get directions. I say “Hey Siri, Good Morning” and my office light goes on and my computer wakes up. I say, “Hey Siri, Good Night” and all the lights, televisions, and computers that are on, turn off (or go to sleep). I like the convenience and try to remember to ask it to do more.
