"Hey Google, turn off the den light switch in 30 minutes"
"Sorry, for safety reasons we cannot...."
It's a light. Because it heard "switch" it thinks there might be some power tool connected to it and won't let me set delayed actions. I want to be intelligent with it like "Hey Google, turn turn the lights on when the sun comes up everday" but no one has gone to that next step.
Or how about "Hey Google, turn off the tone played when you say Hey Google". These settings aren't accessible from the voice interface itself.
Can't wait for Alexa to fail so my SmartTV will stop nagging me to use integrations I will never use. Anti-competitive but whatevs.
