Not necessarily, looking around Ali Express there are 2 human presence sensors. One of them is “enhanced infrared” and the other very clearly says it uses radar.

Can these differentiate between pets and humans?
I’ve always wondered why there isn’t an off the shelf sensor for detecting room presesnsce by monitoring objects passing through a door way. Like a laser line being broken and then height eliminates pets from being detected.

It is now available on Aliexpress, but the price is quite steep at approx 100 EUR.
Thanks for the heads up, bought one to test but at this price will be hard to have a lot around the house 
already gone! 8 hours!!! dang
Ahhhh, also want one.
Any hints where we can buy them? (I am from austria)
Can’t find them anywhere on AliExpress
Thx
I have looked daily at aliexpress, once to twice a week they appear. Got one already at home and 2 more are on the way. But nearly 100€, they are really expensive.
Also looking at aliexpress daily.
But sadly not got a single one 
For Germany i can see three offers at the moment. Maybe it is different for austria?
Sadly nothing available at present on aliexpress…

You are my hero!!!
I have waited for this very long, since the sensor was announced at the beginning of this year.
With your help i could finally order two pieces.
I have looked at aliexpress multiple times a day, also today but did not found it.
So thanks a lot!
And does the device deliver what it promises?
Yes, for me it does. It recognizes me even if i am sitting still and only breathing, so this little movement is enough. I am using it for about 2 weeks and it does it’s job for 100%, i had not even one failure.
There is only one disadvantage, it takes about 5 seconds until it shows somebodys there. But since i have a PIR at the door this is not a huge problem, both of them together will deliver what we want.

Nice to hear that. Also some youtube videos shows the same experience like you said.
Do you using them with deconz?
No, i switched to Zigbee2MQTT for it. I was using ZHA before but they are a little bit slower for new devices as Z2M.
ok, thx. There is already an thread in the deconz github: Aqara Presence Sensor FP1 (RTCZCGQ11LM) · Issue #5928 · dresden-elektronik/deconz-rest-plugin · GitHub
Hope an release with the implementation is comming soon.
You can easily find it in Taobao. Only catch is that the portal is entirely in Chinese and even so, the process can be pretty daunting. I’ve just order 3 for a total of US$190 and they even threw in a free xiaomi music box(??). Fingers cross that the delivery indeed comes through!
I got one of these Tuya ones and so of course I took it apart. I haven’t had much time to play with it yet. It has a WBR3 and so can’t be flashed with ESPHOME.
I might start another thread for these…
link to thread if you do. That WBR3 looks very easy to replace with an ESP chip though

Thanks for mentioning Taobao. I had never heard of that site.
Thankfully the owners of my local bar are Chinese so I’ll get them to help me out with this.
