Jokes aside, I have been using siri to control my smart home and set my alarm for nearly ten years now. I haven't really had problems with basic stuff like this.
>Siri turn off the main light in children's bedroom
100% of the time turns of all the lights in children's bedroom. Alexa has no problem with this.
Disappointing to say the least. Completely useless, I was going to get an Android this year on upgrade cycle. Will check this out first.
Not in the same request. I often want to turn off 2 lights and the other on, I have to build scenes to do this
"Siri, lights out everywhere" - "okay, which room".
"Siri, start a stopwatch" - runs the App "Stopwatch" without starting it
Such errors happen maybe 50% of the time. You can never just ask something without double-checking afterwards.
