Aqara Presence Sensor FP2, mmWave Radar Wired Smart Motion Sensor, Zone Positioning, Multi-Person & Fall Detection, Supports HomeKit, Alexa, Google Home, and Home Assistant, 2.4 GHz Wi-Fi Required

This product is absolutely amazing. I love having the ability to set multiple zones and each having different routines/automations. It is very easy to use and not having to worry about batteries is a major plus. If it's this good now, I can't wait to see the company's future products. Well worth the price! Update, still works very well. Once in awhile it has detection issues where one person won't be detected. I would like to see a microwave sensor that would really add functionality. With this one sensor I was able to remove 4 motion sensors. I can't wait to see the next version of this amazing sensor. No batteries required+++

I've been incredibly excited for this to come out. I was able to purchase an FP1 model from Alibaba a few months back, which was never sold in the US, and it had promise but the motion detection capabilities were very lacking. I had to pair it with an Aqara motion sensor to get the best results. So when they talked about this version I was excited to see the updates made. Overall I really like this product but be warned, it's not perfect and definitely needs to be tweaked, hopefully future software updates will fix some of the things I ran into when setting it up. You really need to set up your zones in the Aqara app before you start messing with it in Homekit. I was able to purchase 2 of these, one for my kitchen/living room and the other in my master bathroom to replace the FP1 and Aqara motion sensor. For the kitchen one I've set up 4 total zones to control my Homekit devices, the main one being in the kitchen where I have 2 NanoLeaf lightstrips under my cabinets. When you walk into the kitchen the lights will turn on and when you walk out they'll turn off. Took a bit of time to get the zones worked out correctly but after messing with it I was able to get a good result. It's not perfect as it sometimes doesn't register that you've entered the kitchen or left but I'd say since tweaking everything in the beginning it works 90-95% of the time as I'd expect. In the master bathroom I set up 4 zones with 2 primarily being used to control devices. The bathroom area turns on the main lights from my Meross dimmer switch and the shower area turns on the shower light and shower fan with both regular Meross switches. Initial placement didn't work out very well as the bathroom mirror seems to mess with the sensor so I moved it to be over the mirror to get it out of the sensor's view and that seems to have fixed a lot of the initial issues I was having. The glass shower door seems to mess with it a little bit but overall like the kitchen one it's working 90-95% of the time as I would hope. I think after some more software updates this will be even better over time. The motion sensing actually works really well when it's functioning properly. It's incredibly fast, even faster than the regular Aqara motion sensors. The design of the FP2 is better than the FP1 as it's flatter and you can remove the cord from the sensor itself which uses USB C. The mount is very smart in my opinion as it is magnetic. So you get an adhesive sticker that you put the included metal disk on and your sensor sticks to the magnet which makes it so much more convenient to take off if needed. All in all I'm happy with the purchase but I will say it's a bit overpriced. I was hoping for this to cost around $50 so when I saw $82.99 I was in shock, thankfully at launch they did have a 15% coupon that helped a bit but I'd say if you can wait I'd wait for the price to drop a bit.

Got this to use for presence detection in my bedroom. Unfortunately it has far too many problems to be useful. Minimal annoyance, this comes with a short USB cord but does not come with a power supply so you'll have to buy that separately. That's probably the nicest thing I can say about the product though. First, the setup is quite annoying as it requires an app with an account to set up the sensor, even if you only want to use it local with Homekit connectivity. There are also many confusing, contradictory, and vague labels and descriptions in the app that I'm guessing are related to badly translated words or unknown differences between parts of the world and no good descriptions such as which sensitivity is for what size room in quantifiable units. It is also very vague and confusing how you set up the detection zones/squares and then attempting to use the guided/automatic setup generates errors saying something can't overlap but doesn't really explain what is overlapping or wrong to guess how to fix it. Worth noting, Homekit integration (at least with Home Assistant) only shows a true/false indication of presence in a zone, not the count of how many people are in a zone like the Aqara app reports. So don't plan to use this to do something like tell if you have 1 vs multiple people in an area. Assuming you get it set up, it doesn't seem to work well. I tried having it in the middle of a wall as suggested, as well as in different corners of the room. All of these had massive mis-detections with numerous false-positive and false-negative results. I tried running the "AI learning" mode, however it didn't seem to help much. If I ran "learning" with my ceiling fan off, it would work decently until I turned the fan on or the blades were moved. If I ran "AI learning" with the ceiling fan on it would work slightly better on false-positives but frequently failed to detect people actually in the room. I'd also tried the "ignore pets" mode (which warns it will miss children) but it didn't actually seem to do anything for reducing false-positives from either of our dogs. Even more confusingly it seemed like it more-frequently would "lose track of" our bigger dog (around 50lb) and more frequently thought our smaller dog (around 40lb) was a person. The other very annoying thing I found was it seemed to have false-detection on stuff that can move around - for example the pillows on my bed being piled differently seemed to be detected as another person and/or it would get confused if I was laying on my side holding a pillow then got out of bed without putting the pillow back up at the headboard would think I was still in the bed after I left the room, or would think 2+ people were suddenly in the room. A similar thing happened when I did laundry and put the laundry bag on a chair until I got to folding the clothes it thought there was a person randomly in the chair. And again with a suitcase that I put down after a weekend trip when I didn't have time to unload and store it immediately. I also briefly tried this in our livingroom but it had many issues there too. It frequently "lost track of" where I was if I sat on the sofa behind a table in the middle of our room for a couple minutes but then getting up would think I was a 2nd person. Do that a couple times and it thinks there are 4 people sitting on the sofa when I'm the only one in the room and would not "clear" the ghost-people until I forced a re-learning or power-cycled the unit (and then that wouldn't fix the problem, just cleared it until I sat down again). It seems this product is aimed at only people who have a perfectly clean room with nothing in the middle and nothing that ever gets set down or moved, and does not have any ceiling fans. I guess maybe an office building or schoolroom might work acceptably but it sure is not suitable for a residence where you have personal belongings that can be picked up or set down on different furniture or might not put everything away instantly upon returning home. It also seems unsuitable if you have pets. I can't recommend this unit, especially given its quite expensive and requires constant power. I'm going to stick with inexpensive PIR sensors.

Got the products next day. Able to set up the system with few minutes. Aqara pressed Sensor FO2 able identify fall accurately. Hope there is a system to call a phone number when it detect a fall or movement in a room. After installing it, I came to learn this is not at all effective system for any thing. This never generate alarm to check for anything. Not able use as monitoring to identify a fall because the system do not have provision for alerting. Who need system where you have observe 24 hrs to identify a fall. If you are going to install on ceiling where you get your power source? If you don’t have a power source in the ceiling you need to spend lot money to install a power plug to power it.

This thing detects everything, but just people. Fans are people. Electronics are people. Even just air are people. And those things move around like ghosts. I have to keep using the app to remove new imaginary people. The set up is ok unless you need it for home assistant. The webkit only integration is garbage. It will just stop working and then you have to reset the whole thing, set up your zones, and start over. It would be nice if they had matter or anything other than homekit. You can't rediscover this device once lost. It does work locally after setup. The app is not great since i have to manual search for the device each time. It's a hassle and not worth the price.

I've watched a lot of YouTube reviews on this sensor. Being on a tight budget made me hold off and try less expensive options. They all failed so I cut back on a few things and ordered this one. MIND BLOWN! This thing is amazing! Most of my house is automated and run by voice via the excessive number of Alexa devices, plugs, and bulbs I have. I was so excited when this arrived that I just plugged it in and balanced it on my TV so I could play around. I haven't even gone through the proper setup for it yet and it's crazy good. I created a few zones and it's truly blown my mind. After dark, when I pass from the livingroom zone to the kitchen zone, a light automatically turns on at a dim level so I don't get blinded in the dark. I return to the livingroom and the light goes off. I'm fortunate to have an open floor plan so the sensor covers a fair amount of my living space. It seems very good at presence detection. When someone else is in the house I pull up the app and you see the other person. I walk away and within a second or two I can see that I've moved away from the other person and we started walking around and the sensor kept updating our location. I can't wait to actually put it in a permanent location and go through the proper setup. I love home automation and will probably make a video about this thing. I haven't tried the ceiling mount for fall detection yet, but I will test that because I've got an elderly father who is a high fall risk and it would bring great piece of mind knowing if he falls, yet again. Especially if he were unable to call for help or he was home alone. If other Aqara devices are as good as this sensor, this will be my new go-to. As finances allow, I'll be adding additional sensors and devices to my nerd ecosystem. I gave it 5 stars for value because you get so much functionality and integrations are simple. Time is money and you could spend far more than the price of this sensor trying, like I did, to find something less expensive only to realize how much money you've spent and how many frustrated hours you've spent trying to get different cheap thing to work or properly integrate.

It works, sort of. This presence sensor was very frustrating to set up and not user-friendly at all. The corner mounting instructions were unclear, and there is no proper mount included, so you basically need a separate or 3D-printed piece. Detection was inconsistent depending on placement, and I had trouble getting reliable results. The biggest issue is the Aqara app and hub. The initial room boundary setup works once, but if you need to reposition or redo it, the process is confusing and nearly impossible to restart. I tried factory resets, unpairing, and reinstalling, and still couldn’t get back to the original setup. While motion detection works and Alexa integration is decent, cheaper sensors perform just as well with far less hassle. Overall, not worth the money. I would not recommend it.

Ok first, earlier reviews that talk about the shortcomings of the app and installation were on point at the time of their writing, however, with updates to the app and device, that is no longer the case. The app is much more intuitive and I’ve had no issues with detection and clearing. So much so, I now have three. I have one in the master bathroom, one in the kitchen, and another in the garage. These are all places where we might be for a while, moving too little for a traditional PIR motion sensor to pick up that we’re still present and so cut off the lights on us. This sensor is double the price of other motion sensors out there, but then there is a Great Deal more going on under the hood with this sensor. Also, the device is not battery powered, which I love. One less to keep up with and given all that it’s doing, you would be constantly changing the batteries anyway. Now if you want to add this device to Home Assistant as I did (it was useless to me otherwise), that too is an absolute breeze as an Apple iOS user, as long as you know how to do it - Apologies , I cannot speak for the Android path. There’s only one video out there describing it. It’s important that you know that this device DOES NOT require the Aqara hub as their customer service will tell you. In fact, it’s actually incompatible with it. The hub is used to add Zigbee based devices and the FP2 is WiFi based. It does not use Matter for the connection either. When adding the FP2 via the Aqara Home app in iOS, the app will automatically add the device to the Apple Home app. Once the entire set up m/config process is complete, you just need to open the Apple Home app, use the ellipsis in the upper-right to navigate to the room you selected for the device and remove either the luminosity or presence sensor from the app. Now open Home Assistant, navigate to Settings —> Devices and look for an as yet configured HomeKit integration with “FP2” in the name. Click configure and it will ask you for the 8 digit PIN code that is just above the QR code located on the swing arm on the back of the FP2 sensor. Once entered, the device is now available for automations and you done. Again, while this process is a cinch to execute, it is anything but intuitive so the process could either use some work or at the least they should make that process clear in the instructions or that the sensor ties itself to Apple Homekit. I also think they should make it clear in both the instructions and on the item page in Amazon that the FP2 cannot be added to the Aqara hub rendering the hub irrelevant for the FP2. Other than that, this sensor hits all the marks and is Exactly what we needed.
