I had this happen in Seoul, the host messages me and asked me to not leave the AC on when I went out (it was a 10-minute walk down to the corner store) - I was a little confused how they knew I'd left it on, so I purposefully left it on and went out, sure enough I got a message as soon as I left. I messaged back and said it wasn't on, and they said they had a camera and could see it's on. I contacted Airbnb and they moved me to a hotel that day, but I wasn't super stoked.
