I had to buy another one of these for my main floor after seeing how it worked in my basement.
I'm very impressed with the accuracy and ability of this presence sensor. I have each of my main living spaces split up into about 7 zones each with their own automations (lights turning on, etc) using HomeAssistant. It's not perfect with accuracy, but it's very close, and better than I've gotten with PIR sensors and ESPHome mmwave sensors. Those sensors only detect presence, but this Aqara sensor gives a highly accurate (again not perfect, but VERY good) 2-dimensional (x,y) representation of where the "presence" is in the room. Accuracy is highest with only one person in the room, and it maxes out at about 5 people as far as telling where they are. However, even with that, it still does a great job with general presence.
For setup, this WILL take a bit of time. No, it's not complicated. But yes, it takes a decent amount of configuration. I love playing with home automation projects, so it wasn't a chore for me, though some people who want things to "just work" may not enjoy the setup. It takes a bit of configuring, because it's extremely versatile.
For my setup, I had to install the Aqara app and configure it through there first. I then calibrated the sensor, setup the zones with names, etc. After that was done, I added it to HomeAssistant, which does not see the x/y map but instead a list of binary sensors for each zone I configured and if presence is detected in them or not. It also exposes a binary sensor that reflects if any of the zones show presence or not. Lastly, it provides a light (lux) sensor which seems pretty accurate.
I haven't tried the other features light sleep monitoring, etc. My main need is presence detection by zone, and I'm very happy so far!
