Alexa is the same and used to work fine. My favorite is “Alexa, turn on the fan” turns on the fan in my mother’s room but “Alexa, turn off the fan”correctly turns off the fan in my bedroom. I ended up getting a HomePod and using home assistant to add all my devices to HomeKit. Shit on Siri all you want but at least she can turn the right devices on and off and on first try.
