Had my eye on this presence sensor for some time for my home automation kit.
Believe this is lowest yet $125.10 from Bing Lee on eBay.
I like supporting Bing Lee and not always Amazon.
Was almost $200 on Amazon and Office works yesterday. Looks like everyone marked it down at the moment but the best deal is on ebay.
(and here is me bagging ebay shitty ebay deals yesterday but this seems like best price ever)
use cashrwards to get a few more cents back.
This is the way.
Which did you go for? I've had a DFRobot one delivered im excited to start playing with.
I have few of them running with esphome. Bought everything from Ali as it was the cheapest for me. Printed some 3d cases and works like a charm.
Lots of diy guides on online. It's very easy using esphome once you get hang of it.
Few helpful links

2. Esp32 + LD2450
3. Apollo Automation github
nice, I have LD2450 arriving this week.
I only found out about the ESP32 super mini c3, so going to get a few of those in.
@impoze: LD2450 are good for moving targets. They are not perfectly reliable for still targets like sitting on couch, chair it might miss if sitting for long time. LD2410 has been almost 99.9% reliable for both moving & still targets. So based on your scenario choose the sensor.
I am using ld2450 for multi target detection in hallway so that I can have different zones using just one sensor. As there would hardly be a still target in that area, I find it reliable. But I tried it in dining room and sometimes it will miss the target sitting.
@ace310: thanks, I've just looked up the differences between the different sensors
Did you also get predesigned enclosures to 3d print?
@impoze: No. Used this one as the design base and update it for my needs.

@ace310: thanks, do I need to get the ESP32-C3 with the 4mb flash?
have you made any combo mmWave with PIR?
@impoze: Used 2410b, the skinny version with connector.

I think in terms of usage both b & c version are the same. So you can pick either. Skinny version was better for me to put it in the case.
@ace310: thanks, we don't need to order the kits with the USB drive right? it just connects direct to the ESP32 which is flashed with ESPhome
@ace310: would you share your esp32-C3 case designs?
The main ones I find are the ESP32 devkits with micro-USB
@impoze: @ace310
***Waaay OT, ur chat was off, so I went out on a limb and took the chance… ***
Regarding a post you made approximately one year ago, one which is due to happen again no doubt.
Now, I'm literally updating as we speak to Unleashed from Plus for only $19. I can handle that for what it gives me. Now I guess I'm Unleashed for 12mths, deb enough time for 7.1 to get solid, but if I don't renew Unleashed - do I revert to Plus or no updates?
I stopped using Windows when it became a subscription. It's a sore spot for me.
So my question is, do you know what impact the discounts have on upgrading to LIFETIME? I would suppose I'm Unleashed for the next 12mths now, so technically it's the 2nd closest financial tier to Lifetime… I'd just like to know what's going to happen if you may.
Really sorry for jumping up on you like that. I'd hoped I might save some money in the near future, and saving money excites me alot!
@parad0x: Sorry, I am not following. What is this about? 1 year is a long time to remember something, even can't recall what you are talking about. Guessing is it unraid server?
@ace310: thanks, that's the one I was going to start tinkering with.
Your design link is broken.
I'm really enjoying the mmWave sensors though, I have one set with a very small zone so it only activates when I step in front of my desk.
@impoze: Is there a guide on how to calibrate it properly? I have it working fine in living room, but somehow it is not able to pickup my 4 yr old.
Care to share your gates settings.
By the way, I also added bme680 to it along with light sensor. Now have got humidity, temp as well.
@ace310: nice, thanks.
in HA, you should have sliders for the still & move thresholds.
But, you can can also do the calibration via engineering mode.
Optimizing LD2410 Presence Detection
I have the AHT20+BMP280 & a BH1750 on the way too.
@impoze: Yes, have been playing those in HA using engineering mode. But can't get the settings right. Either it detects too much to not at all.
@ace310: ah ok,
At the moment, I've just got one running and have just turned all the gates off except 0 & 1 to give me a small zone.
Strange it doesn't pick up your 4yo though, as mine is detecting my cat
As an alternative, I've had good experiences with the Athom presence sensor (runs Esphome) (pricing is USD: https://www.athom.tech/blank-1/human-presence-sensor)
Anyone using these directly in Home Assistant? Via ZHA? Is it supported?
Its Wifi, so you connect into Home Assistant via the Homekit. Works great in Home Assistant
Yes, I set it up with HomeKit integration to make it work.
Thanks folks.
Is it just a binary_sensor in HA?
I suspect you still need the Aqara app to tweak finer details? Can the Aqara app still configure it without an Aqara bridge?
Can the Aqara app still configure it without an Aqara bridge?
Yes, the process is.
1. Set up in Aqara app. Which integrates with HomeKit
2. Add to HA with HomeKit integration, which gives you the lux sensor, presence binary_sensor and if you have zone detection set up in the aqara app you get multiple presence binary_sensors.
@NigelTufnel: Thank you. Can you go back to the Aqara app after step 2 if you needed to make changes?
@jaydisc: Yes, you can still make changes on your Aqara app, but I'm not sure if it will reflect on your HA immediately without going through the process outlined by @NigelTufnel again.
Add apple home kit integration to Hass and it shows up and can be added as device to Hass.
Honestly not seeing the use case for me just yet for this device. Will spend some .ore time with it.
Ive been pondering trying these mmwave sensors, but for the price i think im happy sticking with the Xiaomi/Aqara PIR sensors
This opens up alot more then just is someone in the room, its more like:
- is someone at the couch (Turn on TV)
- is someone at office Desk (Turn on Lightbar and Monitor, Bring Laptop out of Sleep)
- Is someone not in Kitchen (Turn off Kitchen Lights)
Also no need to wave hand to say i'm still in the room like you do with a PIR
I take you need one sensor in each room?
If it's open planned you can usually get away with a single one. But yea one per area
True. Once they go a little cheaper i will give them a try
Correct, I use one with an Athom tasmota IR blaster to pause and unpause the TV/fetch/foxtel when people walk in/out of room :)
These can also be ceiling mounted for Fall Detection for Older residents
if (fall detected) then (disco lights):ON
You can buy ten tuya versions of this for that price.
Where is the tuya ones
Are you talking about the same thing? Presence vs PIR sensors.
Yes mmwave presence etc
Link please
@asa79: https://vi.aliexpress.com/item/1005004961301451.html These are the ones I'm using with zigbee2mqtt. Also has a rudimentary lux sensor inside.
@Xistn: I'm sure you can add air quality sensors into the mix and have brown lights come on when you've had too many beans
@bdl: I have couple of tuya based zigbee mmwave sensors not the same but similar. They work great and haven't missed a bit for almost 6 months now, but remember they flood messages every second to your zigbee network. So if you have few of them, it will bring the zigbee network down. So won't recommend them if you plan on installing more than 2/3 in the house.
@ace310: I've got five or six running per property at two properties (ZY-M100-L and ZY-M100-S_2) … and my Zigbee network stability is fine. Running z2m with a Sonoff ZBDongle-P at each.
You may want to check your coordinator if your zb network is falling over frequently. When you check your coordinator logs, can you see what messages are being spammed?
@bdl: I have a similar AliExpress mmwave radar in my thunderbox and it indeed spams the network, in my case it's reporting: "LQI: 127!" reporting it's signal strength every few seconds for some reason. Definitely a bug in the firmware but it hasn't broken my network
@Ezekiel2320: you need to get the new one is better with regards to spam, the one mentioned here https://smarthomescene.com/reviews/new-tuya-24ghz-zigbee-pre…
@RaihaX: Interesting. Might get the new one for my kitchen. I use this mains powered one with the relay to control the exhaust fan, saved on a 2nd smart device https://smarthomescene.com/reviews/zigbee-presence-sensor-wi…
@Ezekiel2320: Does z2m have a way you can filter/suppress the extraneous messages? I've never dived that deep into it…
@bdl: Probably, I just disabled a few entities in HA that I'm not planning on using anyway, Lux meter etc. I haven't had any issues
@bdl: My zigbee network is fine. Never said about stability issues. But I can see the full message with all values every second from it. So definitely flooding it. It is well documented and lots info on reddit about it. So it's not just me.
My coordinator is perfectly fine and running strong for almost 5 years now.
@ace310: Wow, was just trying to help. Just checked my z2m logs and no spamming for the models I listed above so you may want to give them a try. They don't have a relay like the model you're using, though.
@ace310: If you haven't seen them yet, check out the d1 mini's on aliexpress, too - nice and mini (although they don't have bluetooth).
Once you start adding sensors to the boards it does get addictive, doesn't it :) My letterbox monitoring (using a lux sensor) ESP turned into a frankensensor with a garage beam , temp, humidity and pressure sensor somehow by accident :)
@bdl: Yeh, I skipped on d1 mini as wanted to add bluetooth proxy along with other things where I feel I need them. Though haven't used the proxy part yet, but plan to do something with it once I have time. I like this bermuda triangulation and want to try it out
Anyone can share experience in how the Tuya or SmartLife would integrate with SmartThings: do they connect at all out of box with some available driver, how are the zones managed in SmartThings?
@MerlinKlendatu: I don't have a Smarthings hub but from memory the ST hub will be able to see the Tuya zb devices but can't do anything with them. You're better off going generic zigbee coordinator/hub so you're not locking yourself into a single ecosystem of sensors.
is the same as just making your own with esp32 + ld2410/sensor of your choice but I do think the FP2 is great with regards to its area segregation and multi tracking capability. I use one for my open space as I find it works well.
The rest of the house uses the cheaper diy alternative.
ld2450 has multi tracking & zoning similar to FP2.
Yep that is true - the FP2 I guess put it in a user friendlier package.
Anyone have a FP1? what is the advantage of the FP2?
Anyone can share experience in how the Aqara FP2 integrates with SmartThings (eg connect, zones)?
I don't think it does… You can connect the aqara to Google/Amazon, but not to Smart things (Samsung). You need Home Assistant to bring those ecosystems together.
Damn sold out already, these are good
I have homeassistant. When do i need to get a hub eg. tapo hub or aqara hub?
For example tapo temperature & humity or tapo contact sensor says hub. So even though I have HA do i now need to buy another hub??
Sometimes these listings say hub required?
I really don't get it. Help!!! I'm new to HA.
Home Assistant is the bridge. If you want to integrate with zigbee devices, you will need a zigbee dongle attached to home assistant.
Depends on the device too.
Was reading about Aqara ZigBee locks - they won't talk to anything other than own Aqara ZigBee bridge.
any recommendations?
I have HA but then end up with multiple hubs and bridges.
Tapo Hub and Zigbee bridge?
This is not what I had in mind when starting out with HA…
Still can get it here at $129 with code JULSNS directly from aqara https://www.ebay.com.au/itm/385703342402
Screek experience anyone?
I returned my aqara.

Neat!
I'm waiting for my mmWave sensors to arrive and build one with ESPhome.
