A simple but really annoying example why Siri and/or iOS get my nerve is HomeKit: “Turn my living room heather 1 degree up/hotter” Siri can’t do it. Why such a simple task is not possible?
Siri should look into my home devices find the heater, read the temperature and should turn it hotter.
Another example: play song x in my living room/AppleTV. Song starts playing on the device I asked Siri from and not on my Apple TV.
