Is the author reads this, how does the system cope with multiple rooms in the same house, maybe a two or three storeys house?
Yes, you’re both correct:
You need one sensor for each area you want to monitor independently. With devices more capable than the ESP32‑S3, the coverage would likely be greater.
The ESP32‑C6, in particular, offers significantly better performance. Check out this comparison video from Espressif: https://www.youtube.com/watch?v=JjdpzM6zVJ8
