I’d like to add some “real” presence detection sensors into some of my rooms. Not only motion sensors, but presence detectors, which also detect if someone isn’t moving (like sitting on a table working/reading, …).
presently available tech stacks are:
I’m open to others also, if they’re reasonable with some kinda hardware hubs or stuff.
Are there some good ones available on the market, which aren’t over-the-top expensive! 
Besides the usual motion sensors there are things like room-asssistant which could be run on a Pi Zero.
I might wait though for the new Xiaomi device announced as this seems to be finally (?) a real solution for in room presence detection. Not cheap though.
There are some radar based presence sensors for up to 200€/$, and around 60€/$ for the FP1 doesn’t seem expensive here - if it really meets the expectation.
…but the room-assistant thingy brings me to an idea: my usecase is to track human presence in specific rooms for heating regulation - and in 99,99% of all time, my family wears their smartphones like a part of their body… so, simple Bluetooth tracking from an Pi (I’ve got some lying around here) or even a ESP8266/EP32 would be another (bridging) solution. Thanks for the hint!
Compared to those yes, compared to the normal motion sensors its a lot.
But agreed, this is comparing apples and oranges kind of.
I am looking forward testing the FP1 once available.
I do have a room-assistant instance running as testing since about 1 year and it surprisingly works well.
From an ESP point of view, there is also this post here, maybe of interest as it uses the same functionality.
is Aqara FP1 supported by xiaomi binding?
Here is a interesting video about this new type of sensor.
Here is a review about a cheap Tuya device with this sensor:
Like Andreas says in the video, there might be cheap and good devices in the near future on the market.
I will stay tuned for this. 
Anyone tried one of these in DIY? I’m still looking, btw!
This looks absolutly great:
But can we add it to openhab 3 as well?
as it’s running on ESP32 - ESPHome, you can configure, what’s on your mind. I’d bet it already has some MQTT-based communication already ootb.
Then use MQTT to integrate it.
Problem: seems all waves already sold out, but you could check for the components and put them together yourself.
Are you still looking for presence sensors? I just bought a couple of Sonoff SZNB-06P sensors that are promising.
Since this topic is kind of old and outdated.. I’m wondering if anyone has a promising presence sensor which can be connected to Openhab.
I was trying to figure out which one to buy, but lost in the sea..
I have a ton of Zwave and Wifi devices (Shell), and a Tuya garage door opener. No Zigbee yet.
What I’ve seen is some of the Wenzhi devices sold from china.. they come as Zigbee or Wifi devies as well.. not much info if those are compatible with OH or not.
Aquara FP2 seems to be not working properly with Openhab according to several topics..unless u have some homekit solution (although it seems FP2 has the best config and presence sensing capabilites).
If you can share some examples (not trying to filer based on wired or battery powered devices) which device are you using and is working well with OH, I’d appreciate!
In general:
FYI, when a thread is this old, it’s often better to just start a fresh one and link to the old one for reference. That way, your post will appear as ‘new’ and get more visibility.
I also waited far too long to jump on the ZigBee train - and now I love it!
Most devices are inexpensive and offer local integration without the need for a (perhaps soon-to-shutdown) cloud.
My presence detectors are those:
If you can place them correctly they do work quite impressive and detect you sitting on your desk and even if you’re sleeping most of the time.
plus they work as a so-called router: meaning the relay information between ZigBee devices, kinda like a access point in WiFi-terms.
you’ll need a “coordinator”, which could be an inexpensive USB-dongle and either install zigbee2mqtt on a dedicated host (RaspberryPi) or in parallel to your openHAB - there’s also a zigbee2mqtt setup within openHABian.
and you can browse here as Russ pointed out to search for any and all supported devices for other use cases:
Thanks guys, I’ll check the supported device list and also will check the SNZB-06P.
It will be my 1st Zigbee device, but luckily there are plenty of tutorials and treads in the forum so i’m confident 
Maybe not the best topic to continue the discussion but as you guys said that u are using the SONOFF SNZB-06P I’d like to have a question.
I’m about to order a few Zigbee devices from Aliexpress to play with them a little bit.
The SNZB-06P is one of them, but I found this at the specification of the device in Ali..
”(Note: The SNZB-06P needs to be connected to a Sonoff Zigbee gateway.)”
Just as the Whenzy ceiling presence detector, it says:
“Tuya ZigBee gateway is required for this ZigBee human presence sensor,performing as the center bridge for all Tuya ZigBee smart devices with extremely stable signal and a really good necessity for whole-house intelligence.(note:Tuya ZigBee hub is highly recommended for its wider compatibility than other hubs)”
I’m a little bit confused as the Zigbee2MQTT.IO page says these devices can be used via MQTT.
I’ve already ordered a SMLIGHT SLZB-06M Zigbee Ethernet, PoE, USB, Wi-Fi adapter, to work with OH.
Beside that coordinator/adapter will I need anything else, or setting up the Mosquito in Openhabian using this zigbee stick, will I be able to add these devices locally without any cloud thingy?
No / yes
With a zigbee-coordinator and software to coordinate(z2m) you should be good to go.
Please read through the zigbee2mqtt.io website. All your answers are there.
In short you need:
I’m using a bunch of SNZB-06P with Sonoff Zigbee 3.0 USB Dongle Plus (EFR32MG21). There’s no need for an additional gateway.

(please know, a MQTT server is a completely different kind of “transportation” for information. It’s not a internal component/plugin/binding/whatever of zigbee2mqtt or even openHAB. It’s just a way of transporting information. It’s even stateful, if you define the mqtt-messages as “retain”. Please read https://mqtt.org/ for an introduction of what MQTT is.
Does yours ever stop working? Mine works very well for 1 to 3 months, then gets ‘stuck’ - either on or off. Then I power cycle it and it works again very well for 1 to 3 months.
Never encountered this behaviour. Have them running since… November I think.
I’ve had this happen a handful of times, but as far as I know they only get stuck in an on state.
I seem to think that changing the sensitivity will get it going again, but I could be wrong about that. It’s been awhile.
