It seems the page where the firmware updates used to be no longer exists.
https://www.aqara.com/us/version/presence-sensor-fp2
Also, Amazon currently has an $8 coupon, bringing the cost down to $74.99.
Hopefully these two changes aren’t correlated.
@ellchester, exactly my thoughts. I bought it because of the quick reaction. But its almost slower then my aqara motion detector…

Hey, I just get my aqara FP2, I have 40+ zigbee sensors and Im working with Home Assitant, I read can I connect the FP2 without any aqara hub to my Home Assistant, I tried to connect the fp2 and I got error when trying to bind, the device cant bind, I have 4 Wifi networks and Firewall and I tried to change WIFI and of course I tried 2.4GHZ but its not working, maybe I need to open ports or something? I sent message to the seller and he said I need a hub so I get aqara hub and tried to connect to aqara app and same problem, I have home kit and maybe this making some problems, if I try to connect to home kit It success to add it to my home kit dashboard but no responding , maybe someone can help me please??
thanks!!
this is the error code message
You don’t need a Aquara hub.
- Download the Aquara app on you mobile phone
- Connect your mobile phone to the same Wi-Fi network as the FP2
- Reset FP2 to factory default
- Search and add the FP2 sensor to your WiFi netwerk/Aquara app
- Homekit controller integration in Home Assistant will automatically find the FP2 sensor.
You don’t need open ports. My sensor is completely blocked from the internet. I only open communications to update the sensor.
You are saying: I’m user homekit…Is this a seperated app on your phone or do you mean the home kit integration from Home Assistant.
If it is a seperated app > Delete the device from that app if added, otherwise Home Assistant can’t find it.
when I adding its fails in bind progress, I have homekit integration and I have IOS so I have “my home kit”
Delete the FP2 device in the my home kit, from your Eaten apple device environment 
Add it to the aquara app. When added to the aquara app it is possible you have to delete the FP2 from your “my home kit” again.
Is this a 2.4 Ghz ONLY network? It should be.
Try another Wi-Fi channel > 1, 6 or 11

Same problem, other device
This is exactly how I added my FP2s to HA. But, mine weren’t auto-discovered by the Homekit Controller until I powered them down and powered them back, up again. After that, they were discovered and work flawlessly. Just be sure to set them up fully in the app ie edges, detection zones etc
Hi everyone, hoping you can help me
I have the FP2 in a certain position but wasn’t working properly (I had it on HA already with 6 zones) so I changed position and is working better, but I had to change the zones (now 5) but HA does not seems to be updated
Is there anything I can do to update zones in HA?
Looking for inspiration! I just got my first FP2 and set it up in a combined living room/dining room, and have set up automations to control lights depending on where there is presence. It works great so far. So I am considering buying one for other locations in the house, and I am looking for inspiration on what other types of automation people have done? Blinds, alarms, fans, AC, car charging or whatever creative idea anyone has had that is controlled by the FP2. Inspire me 
I have some combination of all those.
- I have fans in each room that come on only if the room is occupied and the temperature is above a certain threshold.
- In my dining area I have a light that comes on when you come into the area if the light level is below a certain threshold.
- In the main bedroom I have the blinds tilt 85% if it’s after a defined bedtime and the room becomes occupied for 2 minutes. Related to that, in the morning after the room is unoccupied for a couple minutes, the blinds open back up.
- In the living room I have some decorative lighting in a cabinet that comes on if the light level is below a certain threshold and the room is occupied.
I’ve avoided doing the “main” lights in my rooms because the FP2s still don’t properly detect presence/absence all the time. I’m OK with a fan or decorative light turning on/off at a strange moment, but not the main lights.

I use the FP2 for a few months now on the mainlights of the livingroom and kitchen and do not detect such problems.
I think it is related to a positioning of the FP2, or environmental variable that causes issues.

The performance of the FP2 is very much dependent on how well it is set up in the Aqara app. You need to be quite meticulous in creating edges, interference zones, exits and entrances and any detection zones. I spent quite a bit of time just sitting in the room and watching what happened as people moved in and out and around the room, also watching for false positives from things like curtains and large plants moving. Once I was happy that everything was being tracked accurately, including occupation and vacation of a room, I left it at that. I’m sure I read somewhere that one of the key aspects of ensuring good performance was getting the room vacation ie non-occupation sorted. How quickly does the sensor change from detected to clear when everyone has left the room.

Did you guys figure out how to retrieve the number of persons inside each zone ?
Detected or Not Detected is fine, but I would like to get the number of persons detected.

I don’t think that is available through HomeKit, and thus isn’t exposed to HA when you add it as a HomeKit device. Someone would probably have to reverse engineer the entire API and then do a man in the middle thing to get all the data the FP2 is sending back to Aqara and use it locally instead of in the app.

Just an FYI as this seems to be the most active FP2 topic, this chart posted on reddit may be useful for determining your FP2 sensitivity settings:

Hey guys, will Matter 1.2 receive support to presence sensor, like Aqara FP2?
Im findign have two of these sensors to be the worst thing I have buy seems worse than having Vista as a OS no matter how I set it up or how I try its got a terrible performance.
Id also like to disipoint you on cost of Hue Bulbs being do expentive for a bulb rather it go to more important things on me to keep me alive than a bulb bit anyway I figured ways around now like I always do to save on costs and can do the same on my setup as a HUe bulb can do took me a while but like anything once figured it becomes easier!
I have smart switches on stairs with smart bulbs now colour and working great but as for these sensors in a different setup different rooms find trash and would not or be bothered with them any more thay caused me more issues than anything I have ever bought even a Christmas trees easier to put up
I’m very disappointed with tthem. Lights and things seem to blink when I tell it to turm them on if motion is detected and they also never seem to find the walls or myself correctly even though I tried at different position on the walls in corners too at different heights as made no differences. Im still using normal sensors now.
I cannot help you on this sorry but maybe you can help me get my normal Aqara sensors into Homekit on my ipad if you can help? I m also unable to do anything with thees FP2 sensors seem more trouble than what they are!
But would also be interesting to know if they can just be added into HA which will make it less confusing but there is oither things in there software by the looks of it that I dont think
