AqaraPresence Sensor FP2 Bracket Set, mmWave Radar Wired Motion Sensor, Zone Positioning, Multi-Person & Fall Detection, Supports HomeKit, Alexa, and Home Assistant, 2.4 GHz Wi-Fi Required

OK, so far I am very pleased with this. I purchased this to test it for two reasons. My wife suffers from a couple of debilitating neurological disorders. So far I have been using it for home automation. With some "if this then that" I am using it to turn on the bathroom lights and fan for my wife if she enters the bathroom during the day, and only one of the lights dim at night. It has been working great and reliably. No I want to order another one soon and try it for the fall detection. If that works as well I will order several for throughout the house. I will post updates as we progress.

Setting this up with the app for person detection in my living room was straightforward. First experiment was to pipe the sensors into Home Assistant and create an automation that pauses the TV when it detects two people watching and one gets up. This impressed my wife enough that she stopped giving me grief about the weird sensor on the shelf.Unless something has changed since I set it up, it's essentially a requirement to set it up in the proprietary app first, but it then exposes A LOT of sensors to Home Assistant for playing with. I think you can also wire it into HomeKit.The stated 430 sq ft room size seems about right. Our living room is about 21x20, but then is fully open to the kitchen, and detection beyond that //kind of// works, but I wouldn't rely on it for something you expect to work all the time. It's a bit tricky to find a good mounting spot that gives you the best performance without it being somewhere obvious near eye-level.Ceiling mounting seems to only be for Fall Detection.Seems to struggle a bit with more than a couple people in the room for my applications. The cat confuses it.

It takes patience to get it to connect to 2.4 if you have a dual band router that you can not switch off bands....my cable company has dual band router however no way to turn one off. Once you get it to connect to your 2.4 band it works great...! I had 1 that just wouldn't connect, I exchanged it and opened the new one plugged it in and was instantly connected....I really can't explain it ...however once I got the new one it has been working great...!

The intended functionality of this sensor is great; however, it does not function as intended. A major issue I experienced is that it interferes with other Aqara devices. When the sensor detects a room is unoccupied and turns off the light via Aqara light switch, the other Aqara light in the other room turns on. I checked the automation setup in the Aqara app and there were interactions between the sensor and light switch in one room and the light switch in the other, so the problem was not with the automation setup. I switched to the FP1E sensor and did not experience this problem anymore.

I gotta say after having 2 of these units for a few months now, I wouldn't ever get a wifi presence sensor again. It's just not reliable enough. After comparing the Fp1e that is zigbee based, it's 100x faster and more reliable. The fp2 is not quick to trigger, nor is it reliable at all.This could be due to my network or interference with other devices, but that still just points to not using wifi for automations. I really only went with this because of its capabilities to have zones, but in reality I don't think I need that. I am using smartthings for these, but have recently got a home assistant hub that I can try and use instead to see if it's any better, but I'm not going to hold my breath.If I had to do it all over again, I'd get all fp1e. I'm really disappointed in having spent $160 on two of these devices and now I can't return them. I'd honestly stay away.

Really cool in Home Assistant. The setup is a bit if a pain.1. Be sure when you use their app to install be on the WIFI network you want it to connect to.* Being a WIFI network that uses WPAx-Enterprise will fail the install. Use WPAx-personal on your IoT WIFI network2. Be sure the WIFI network has internet access* You'll get error codes with vague resolutions3. You need a solid connection during the setup4. Configure you zones through the phone app.* Each zone will show up as an entity.5. You need to 8 digit code next to the barcode on the device to connect it to HA6. The phone app setup connects to Apple or Google. You'll need to remove the device from that app before HA will see it.

Fácil instalación en la pared y un muy buen funcionamiento, el único inconveniente que le veo es que es complicado determinar el área de cobertura; además dicen que no pero si es sensible a mascotas entonces la luz se pasa encendiendo y apagando si tus mascotas andan por allí.

Setup is a pain. Reading the failure fine print helped. I turned off my router. I set up another router which allowed me to run 2.4GHz only. The FP2 connected. I switched back to the good router and it worked. Aqara should include that instruction in the manual.I have several 2.4GHz only devices and not one has ever required turning off 5GHz in order to connect. Aqara should correct the firmware.Aqara claims that the FP2 works with Alexa. This is only partially true. The presence sensor shows up in the Alexa app as a motion sensor. Hence the bad revues on Redit and elsewhere. In fact, it does work as a presence sensor in the Alexa app. Aqara needs to correct the Alexa skill verbiage. Note the light sensor does not work in the Alexa app.Smart home reviewers claim the FP2 setup and routines are so powerful, yet none are available without the Aqara hob and other Aqara devices. This is misleading advice. Aqara has supplied the devices to these reviewers and so has some control over content. Aqara needs to correct these errors.I have read that the FP2 will be Matter certified. I hope this is true and that I can look forward to improved operation without Alexa adding inconsistent delays as a go between. Direct local operation between the FP2 and Homey Pro controller is my dream. I hope Aqara will make it a reality. In the meantime, the FP2 is useful enough I now have 2.
