Hey thanks for the instructions 
quick question how do you find aqara fp2? Does it give false signals or not detect people in the zones? Is it worth buying one?
I also am not on Apple ecosystem and all I did was firstly, add it to my home network using Android Aqara app
Then when I go to my HA - within the integration, it automatically picked it up as a new discovered device.
So I basically only had to click on configure, put the PIN in, then submit.
I’ve been finding them scary accurate even the movement tracking is pretty much on point in the Aqara app.

This is my first time using any kind of motion sensor. It’s definitely a very good device, and the ability to do zones is the reason I got it (I have a great room where I really need automations to happen in the dining area but not the rest of the room). It seems very quick to recognize someone when they come into the room, but I have to be really careful not to get anything between my belly and the sensor or it doesn’t realize I’m still breathing and in the room. In the bedroom it definitely can’t tell I’m still there when sleeping even though all the reviews claim to will do that. I guess I sleep too peacefully. I’m still struggling to get the kitchen one to be reliable. About half the space is now labeled as an interference zone, so I think this weekend I’m going to try a different position and see if that helps.
Overall I like them, but they are not reliable enough in my space for me to build automations that control the main lights. I’m hoping a combination of fine tuning and perhaps some additional firmware updates will help.

Just power cycle/unplug the Fp2 Also make sure to get the HomeKit code off the back of the Fp2
I’ve read a couple of places that putting these high up in a corner but it seems to me with the way its mounted and the way the app shows the device this was not the intended mounting position, are they supposed to go high up on a straight wall at an angle perhaps?
Just wondering what successes people have had with what position with the understanding that each room is different and one successes doesn’t mean success for all?
Even in the same room, I’ve had to try it on different walls and at different locations to get it working right. But once I found the sweet spot it was great.
I’m having trouble finding the sweet spot, and haven’t quite figured out the best installation method, or location.
What worked best for you?
I had to set the sensitivity too high & far to be able to pickup anything under 150 lbs. Most likely because the FP2 is 8’ high. Had to use 2 Fp2’s in a couple of larger rooms. The fp2’s pick me up fine no mater the sensitivity, I’m around 220 Lbs. No clue why they say low is good for large complicated rooms. I have live plants and ceiling fans all I did was set those areas to interference and all works well.
It’s best to just use common sense. Choose a spot which adheres to two conditions:
a) the sensor can see humans in all relevant places in the room. This usually indicates a higher position (a lower position could block its line of sight because of furniture)
b) the sensor cannot see moving non-human materials (curtains, fans, plants, etc). This usually means to avoid the walls of the room (where those curtains and plants are often located), and to aim it downwards (to avoid ceiling fans).
Since meeting those conditions is very specific for the room at hand, it makes no sense to copy-paste the location from someone else. I hope this helps.

Got mine Sunday 23rd April, worked great till today. 
Detection/No detection got very sluggish. Tried a factory rest, failed auto calibration every time when re-paired to the app and would no longer detect anything(lux was ok).
Being returned to Amazon but zero stock.
I was just going to see if anyone else had this issue. Exact same issue for me, was working fine yesterday. Configuration fails each time now. Will see if there is any new update in next few days before trying to return it.
Have you tried a different power supply? Not sure where you’re located, but in the USA, the device ships without a power supply. Make sure you’re using a decent 5V and at least 1AMP power supply to see if that might make any difference.
Thanks for the suggestion but unfortunately makes no difference. I have another FP2 that’s fine and it’s power supply makes no difference. Just strange how it was working fine. Don’t know if it overheated or memory is full etc.
Edit: Dug out an old ipad and set up seems to work ok, so looks there is an issue with the android app.

I’ve noticed some weirdness/slowness with the Android and iOS Aqara app. Home assistant zones seem to always be fast and accurate. Even if the Aqara app is acting weird. I’m not too concerned with following a little blue dot around. I actually uninstall the Aqara app when I’m done configuring.
The iOS app on an iPhone is basically garbage from what I can tell. For me it only works for about 4 minutes at a time before it stops updating anything unless I refresh the page, restart the app, and sometimes restart the phone. I also finally pulled an iPad out tonight, and it seems more responsive.

Maybe more of a automation question, but how are people finding the responsiveness of the zones when grouped? It seems like if you move from one zone to another, there is a moment where both zones are considered unoccupied.
So for sensor groups, there is a moment where occupancy is lost, whereas normally with two sensors grouped, the total occupancy would remain as you move around the combined area.
There integration adds one combined sensor for the entire area, but that would restrict how many combined rooms I could track.
Anyone having an issue when there is more than one person in the room? It works great when its just me but when my wife walks in the room it stops detecting presence in the area I’m in and only follows her.
Available to order from Amazon UK, delivery in ~2 weeks
I’m not grouping my sensors using a helper (which I think is what you’re doing), but I do have a few template sensors that take the reading from a few different zones to define another sensor that I use in automations (i.e. the kitchen zone and living room zone are combined in a template to give me a great room sensor). I’m not seeing any more lag with that template sensor than I am with each individual sensor. There can still be a small lag for the FP2s to sense anything, but not a big one.
I see that from time to time. I can’t tell if it’s an issue with the sensor or the app though. And since HA only exposes presence and not body count, there’s no good way to know.
I’m going way back to this question again, because I think my answer is different now. I have one FP2 in my living area and one in my kitchen area. It’s open concept, and the two sensors were facing each other (but not directly in line with each other). I was having a really hard time with false positives, so I changed the orientation of the one in the kitchen so it’s turned away from the living room one. There is still a little overlap in the zones, but now they only overlap at the edge (previously one each sensor had the other in it’s overlap. With that change all my false positives went away. I think shooting mmwaves at a sensor is Not A Good Thing (which makes sense if I think about it).
