Well I mean it’s true. They just worked correctly, the aqara did not. But yeah I guess network spam could become a problem at some point if you don’t patch them
BTW I opened my Aqara FP1E to find out which sensor chip it uses. The sensor chip itself was impossible to identify as there’s no info on it. But googling some of the other chips that did have info on them, I ended up here: Aqara FP1 Human Presence Sensor Review - SmartHomeScene
Where they state that it has an “Infineon XENSIV BGT60TR13C” sensor. So that’s definitely a very different chip than for example the Wenzhi’s use.
And then googling that chip, I found this link: Aqara FP2 Human Presence Sensor Review - SmartHomeScene Where they state that the FP2 uses the “Texas instruments IWR6843” sensor.
I didn’t even know there were that many companies releasing those sensor chips, very interesting to see that!
That’s quite an interesting website BTW as they review sensors and always seem to open them up to find out what’s inside. For example I’ve read quite a few positive reviews about the Apollo MSR2 and they state it has a LD2410B inside which of course has the S3KM111L.
In fact people always seem to rave about the sensors based on that S3KM111L chip: Apollo MSR2 is popular, the people who use the LD2410B alone are also raving and people seem to like the Wenzhi sensors, which also have that sensor chip (although the disadvantage of course is that spamming)
The Aqara FP2 finding does renew my interest in it BTW, that TI chip seems quite nice. Last time I tried it I was mainly disappointed by the stuck ghosting. Not sure if they resolved that? I might look into that again.
Edit
Like I said I tinkered today a while with the fp1e and fp2 and came to the same conclusion as before: I like the fp1e better than the fp2 but the wenzhi beats them both (if the spam is no deal breaker)
Sorry for my late reply, but isn’t that device sensing rather than human sensing? So whilst you may wear a smartwatch with BT, others may not?
Indeed, it is a different technology, with (slightly) different applications (but some commonality, as well).
Yes, this is one of the main problems with it.
OTOH, you can do cool things like having the HA app on your phone open automatically to the relevant controls for the room you are in.
But all of this is a bit off topic for this thread. I suppose I was just trying to express that I’ve kind of lost interest in continuing to test these mmWave sensors, especially Zigbee based ones.
My current focus is on DIY ESP32 devices (via ESPHome) because they are inexpensive and very flexible (giving you exactly what you need for that location, depending on what sensors you include). You can create quite nice multi-sensors, with mmWave, light level, and other (Bermuda presence and general BLE monitoring), all for just a few dollars. And they are totally configurable on the ESP32 node (update frequency, etc.), and updatable OTA (after initial flashing). Currently I’m finding the combination of all those attributes quite hard to beat.
I guess if there is a downside, it would be the learning curve. ESPHome does make it very easy, but you do need to be at least a bit technically inclined. Well worth the time investment though, IMO, considering all you get in return.
Everyone else is free to continue discussing mmWave sensors, of course. 
For the kind of (bare) sensors I’m using now (with ESPHome), much has already been written, so I won’t get into those here, either.

Perhaps of note to this topic, Athom has released the esp32-based version of their presence/motion/light sensor, which uses the ld2450 and ships with esphome config that includes the ability to set three custom zone coordinates. Now with the Bluetooth proxy feature, it is more comparable to the Everything Presence One, lacking only the temperature and humidity which if you really need you can get separately for only a few dollars more.

FWIW, The Athom seem to me like the most bang for the buck in the “commercial devices made using ESPHome” segment. Injection molded cases, all accessories included, etc.
But they don’t have big social media presence in the HA scene (YouTube and Reddit) like some of their competitors, so you don’t hear them mentioned as often.
To put it less charitably, I quite frankly find their competitors over-hyped and quite over priced (for what they are).

I like a lot the fact that it’s PoE. I’m building a small countryside home and I designed several extra CAT6 cables on the roof to power sensors without the need to route AC and have power bricks everywhere. The idea was to use PoE ports on the switch feeding PoE splitters with USB-C outputs, but if the sensor has PoE already, this is the best option by far. I watched the YouTube video and it seems very cool.
Has anyone tested this PoE version in real life? How does it perform?

Unfortunately that Athom unit is not POE. I’ve got a couple of their earlier units, and was pretty favorably impressed, but I should revisit them, now that config process appears much more streamlined (with GUI tool, instead of a zillion different settings).
BTW, I would highly recommend also looking at a different unit, albeit somewhat higher priced. The Apollo Automation “R Pro-1” has a LOT of capabilities – LD2450 radar & optional LD2412 (for both multi-zone motion & still presence sensing). Temp & humidity sensors; optional CO2 sensor. Has options for desk or in-wall (switchplate) or in-ceiling mounting. And it is definitely POE (or can be powered by USB-C). https://apolloautomation.com/products/r-pro-1
