Believe it or not: This man let AI ensure him a good night’s sleep

Too hot? Too cold? This Bengaluru man has found the perfect balance. Fed up with manually switching his ceiling fan on and off, the X user @the2ndfloorguy built an AI roommate to handle it for him — literally. Using a smart sensor setup, the AI tracks his sleep stages and automatically adjusts the fan so he stays cool without lifting a finger. The image showing a demo of the algorithm went viral, and the internet promptly applauded the creativity.

Let AI take care of it
In the tweet shared on X, the DIY stock image setup shows the smart toggling action points: as the man’s sleep deepens or shallow, the fan’s speed shifts accordingly. The AI’s logic, sensors and voice prompts were cobbled together with off-the-shelf gear and coding know-how — transforming a bedroom climate into an algorithmic butler.

Finally, a real AI friend
Netizens were delighted over this experiment. Comments ranged from “This is the AI roommate we needed,” to “Next upgrade: AI to switch off my alarm & make chai.” Others joked that India has officially outsmarted sleep itself.
