AqaraPresence 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 now own and use two different Presence Detectors. I bought the FP2 Detector because, unlike my first unit, it supports multiple detection zones. Being able to designate detection zones works much better for me. I am glad I made this purchase.The FP2 actually has three modes of operation – Fall Detection, Sleep Monitoring, and Zone Detection. I only use Zone Detection, and have set up 6 out of a maximum of 30 detection zones. The unit’s coverage area is divided into 320 checkerboard squares, and you can configure which of those squares compose each zone that you wish to create.My house has an open concept floor plan, and I have located my FP2 such that it can detect presence in my Kitchen, Dining Room, and Living Room. I have setup zones for controlling the ceiling lights in each of those these rooms, along with several individual lamps in various locations.The competitor’s Presence Detector I purchased earlier detected anything and everything within a 120° angle in front of it that was within a certain distance based on a ballpark sensitivity setting. It failed to detect some areas I wanted included, and detected other areas I didn’t wanted included. The FP2, with its zone detection, resolves that issue. For example, I have a small 2 square zone that encompasses our piano bench, which I use to turn ON the piano music light when and only when someone is sitting there.I noticed this product has some poor reviews. I suspect this is because some users had difficulty getting it setup and configured. I personally was a bit challenged getting mine setup and working, despite already having done lots of automations using dozens of smart devices. For this reason I have deducted one star. However, now that I am familiar with this unit and its capabilities, I would not hesitate to order another one – and I would not consider an alternate cheaper unit as I did for my first presence sensor.The instructions are sparse. I ended up setting it up three times before I got it working like I wanted. I discovered it helps to configure the Edge Zones along the perimeter of the detection area, as well as Entrance & Exit Areas to minimize unwanted detections. I also discovered it helps to be slightly generous on most Detection Zones because the exact location a person is in becomes less precise the further you are located from the sensor, or when a person is near a reflective surface such as a refrigerator.The Aqara App only controls Aqara devices. Thus, out of the box I couldn’t use it to perform any automation! Fortunately, it links to Alexa, and once I linked Aqara to Amazon’s Alexa, I could start controlling the lights and lamps in my house. The Aqara App claims to also link to Home Assistant, Google Home, and IFTTT. I don’t use IFTTT and was unable to get it to link to Home Assistant. For my more complex automations, I use Smartthings since Alexa routines are limited to a single Trigger. Thus, I ended up creating Virtual Switches in Smartthings and used Alexa to flip those switches based on Presence in each of the zones I created. Later, I got a Smartthings Hub which would recognize the FP2, which allowed me to use Smartthings without going through the overhead of Alexa. Smartthings and its ability to use virtual switches allowed me to create more complex routines, such as turning off the lamp between my recliner and couch when some leaves the couch zone and no one is in the recliner zone – but if someone is still using the recliner, only turn Off the far couch lamp (multiple ‘IF’ triggers required).The FP2 has a Luminance meter, but getting that to control whether automated lights are turned On or not when Presence is detected was a big challenge for me. The workaround I initially came up with was to create a dummy zone in Aqara and use Aqara automation to control Home & Away status in that zone based on the Lux level. I then used an Alexa routine that would flip a Smartthings virtual switch based on the Aqara ‘Simple Security System’ device value of Home or Away. Why that functionality couldn’t have been made much more straight forward is beyond me. However, after I got my Smartthings Hub to recognize the FP2, I was able to add conditional triggers in my Smartthings automations that were tied to luminance levels, making FP2 luminance levels easier to include in automations and also make Lux thresholds flexible.The bottom line is that the FP2 is a very capable device. But more capabilities equates to more complexity. Thus, don’t expect to have lots of automation configured and working an hour after unpacking the unit. And unless you have other Aqara devices or a hub that recognizes the FP2, don’t expect to perform to automations until you link it to another App such as Alexa. Note that once you link Aqara to Alexa, you can pretty much do any automation that you would normally do in Alexa. It’s only when your automations get too complex for Alexa that automation understandably becomes a bit more involved, and has to jump through hoops involving products/apps from multiple manufacturers.

Tldr: not that you have a choice since this is backordered, but don't buy this yet.Update 2: after the new firmware update I was excited to see what would happen. It's garbage. Plain and simple. They made the tracking distance 1 meter, which means when someone is walking next to you they steal the tracking. This thing is useless if you live with anyone....including plants, pets, people, TV's, fans, shiny countertops, tile, windows, or doors that open and close. All cause horrible interference, and you cannot simply mark out those places on the map. Aqara is already removing promised features from their website. Don't buy from companies that push products before they are even close to ready...it's embarrassing.Update as this might save someone days of their life: it might work in the future but currently if you tilt this device at all the results aren't good. My best results are 6 feet off the ground and completely horizontal. If you have one of these play with the placement as much as you can before you automate around it. Some places worked initially but degraded over a few days. Increased one star now that I have found a good placement. Will update more as errors get resolved with ota.I've played with the fp2 for 4 days now almost continuously. It's not ready, not even close.The app is horrible. It is slow and locks up all of the time. It's not only not updating my location in the app, sometimes if it is detecting me at all I just fall off of the radar standing 6 feet in front of it. I check in home assistant and I'm not in the zone I'm standing in. Clear view of sight, 6 feet away. This isn't ok.Setting up the devices was also a nightmare. I'm on an Samsung phone (s23) so maybe that had something to do with it but it took over 3 hours to set up both devices (the first time). Constant errors, even though everything was correct. The solution was the just keep trying...tried about 20 times in a row. Also, Bluetooth isnt showing up as a binding option 99% of the time, which is a shame because it works instantly when it comes up.Which brings me to another point...if you remove this device from home assistant, it never resends the homekit info. You have to remove the device from aqara and the readd it. Again...another headache getting everything reconnected.I bought these for the zone detection, which works great when it works and is abysmal other times. I could have achieved my goals quite well with cheaper sensors but the posture detection was an added benefit that I was looking forward to. If aqara launched it like this I don't have much hope.And that brings me to the most frustrating part of this...it was working flawlessly 2 days ago and not skipping a beat. And over the course of two days it started putting me in the wrong locations and only detecting me randomly. At the time of writing this it isn't detecting anything at all and there are 3 of us and a large dog in the room. No the sensor hasn't moved. Hasn't drifted or anything like that. Nothing has changed.There are so many other things that I've found that should have never made it past production. Most of this is bad programming. No clue if the hardware is to blame.

Okay, so let’s talk about this product. It works well but it isn’t without its flaws. I still give it a 5-star review because it’s really better than every motion sensor out there.- Responsive and fast, powered motion and light sensors are the way to go, even with HomeKit automations. You can walk in rooms and zones and it feels fast without lag. I’d grade it a half second to a second.- The app is rough. There’s a ton of settings and they’re kind of all misplaced. Once you’ve got it going, you’ll be in good shape.- Use big zones, granular is not the way to go. The instant this thing moves out of place, zones are all different.- Ghosts appear from time to time but I think it self improves and knows what is what. You can use the reset feature to really help improve it.This sensor is honestly first of its kind. I split my apartment’s kitchen/living room with this and it works flawlessly. Not to mention a wired luminosity sensor really helps with light-based automations.
