I wasn't expecting much, but still it managed to disappoint me.- Installation method is unclear, the app does not do a good job guiding you through installation.- The app is poorly made, a very low quality and obviously Chinese app- It detects random moving stuff that don't exist, for example I was the only one in the living room but the app was detecting 6 people so none of the zones were getting proper presence detection.- When it works, it's too sensitive. I was making food in the kitchen and wasn't moving, and the device was turning the presence sensor on and off constantly and that was turning the kitchen lights on and off. Had to disable the whole automation.

The Aqara PF2 presence sensor is a promising device, but it falls short in a few key areas. The main problems I've experienced are unresponsiveness and false-positives. The sensor sometimes takes a while to detect presence, and it has even detected people in the room when there are none.I've tried everything to troubleshoot these issues, including changing the sensitivity level, calibrating the sensor, updating the firmware, and configuring the entry/exit zones correctly. Unfortunately, nothing has worked. I've even had to set up the device twice, because after the first week it unpaired from the Aqara app and showed a popup with Chinese characters. It still worked in Home Assistant, but I was no longer able to configure anything it in the Aqara app.Despite ... MoreThe Aqara PF2 presence sensor is a promising device, but it falls short in a few key areas.

When it does work, it's a great way to automate your smart home devices. For example, you can use it to turn on the lights when you enter a room, or to turn off the TV when you leave.Overall, I'm disappointed with the Aqara PF2. It's a promising device, but it's too unreliable to recommend. If you're looking for a presence sensor, I would suggest looking elsewhere.
